What Is a Decentralized Exchange (DEX)?

By Matthew Warholak | Growing Wealth, invest, Investing | Comments Off

A decentralized exchange (DEX) is a digital currency exchange that allows users to buy crypto through direct, peer-to-peer cryptocurrency transactions, all over a online platform without an intermediary. It differs from a traditional centralized exchange, where a typical transaction involves a third-party entity (e.g. bank, trading platform, government institution, etc.) that takes custody of user funds, and oversees the security and transfer of assets between two parties.

Decentralization is a fundamental philosophy of blockchain technology and the crypto space. It redistributes authority from a central power, and places it in the hands of users. And the concept of decentralization is reengineering how many conventional financial services operate.

Decentralized exchanges have also grown in popularity over the past couple of years, with spot trading volume slowly shifting away from centralized exchanges, up until early 2022, when “crypto winter” set in.

How a Decentralized Exchange (DEX) Works

Decentralized exchanges provide a decentralized platform that allows users to exchange assets without having to trust their funds with another entity.

With a decentralized exchange, a blockchain, or distributed ledger, takes the place of the third party. By moving critical operations onto a blockchain, the underlying technology may help to eliminate single points of failure, allowing users to have greater control of their assets, and support safer and more transparent trading.

DEXs use smart contracts to execute market transactions by allocating transactions’ operations to autonomous code, but there are multiple variations of order fulfillment with differing degrees of decentralization.

Like digital currencies, decentralized exchanges were created in response to flawed and archaic financial systems that passed along risks of a centralized system to its users. Those risks often include insufficient security, technical issues, and a lack of transparency.

Different Types of Decentralized Exchanges

Full decentralization is more of a philosophy than a rule of thumb, as it’s not very practical based on first-layer blockchain scalability limits. As a result, most decentralized exchanges are actually semi-decentralized, using their own servers and off-chain order books to store data and external programs or entities for the exchange of user assets.

Due to this reliance on centralized components, semi-decentralized exchanges’ operations may be subject to government oversight. However, and perhaps most importantly, users still maintain control of the private keys to their funds.

Although DEXs continue to evolve and operate cross-chain with other DApps, DEXs typically operate a single blockchain. One thing all decentralized exchanges have in common is that they execute orders on chains with smart contracts, and at no point do they take custody of users’ funds.

The Different Types of DEXs
Type	Features
On-Chain Order Books	Processes transactions on a blockchain network, without the inclusion of a third-party
Off-Chain Order Books	Utilizes an off-chain, centralized entity to process transactions and govern the order book
Automated Market Makers	Uses algorithms to automatically price asset pairs in real-time
DEX Aggregators	Compile data from numerous DEXs to increase options and liquidity for traders

On-Chain Order Books

For some decentralized exchanges, transactions are processed on-chain, including modifying and canceling orders. Philosophically, this is the most decentralized and transparent process, because it circumvents the need to trust a third party to handle any orders at any time. However, this approach is not very practical in execution.

By placing all stages of an order onto the blockchain, DEXs go through a time-consuming process of asking every node on the network to permanently store the order via miners, as well as pay a fee.

Some criticize the decentralized crypto exchange model because its slow transaction times allow for front-running, which is when an investor watches the price of an asset closely, waiting at the last minute to buy or sell right before they anticipate the price rising or falling. (Note that this type of “front-running” is different from stock front-running, where an investor purchases a security based on insider information, such as a future event that will impact stock price.)

Others counter that since all orders are published on a public ledger, there is no exclusive opportunity for any select individual to front-run from a traditional perspective. However, it has been questioned whether a miner can front-run by noticing an order before it’s confirmed and force their own order to get added to the blockchain first.

Off-Chain Order Books

DEXs with off-chain order books are still decentralized to some degree, but are somewhat more centralized than their on-chain counterparts. As opposed to orders being stored on the blockchain, off-chain orders are posted elsewhere, such as a centralized entity that governs the order book. Such an entity could exploit access to the order books to front-run or misrepresent orders, however, users’ funds would still be protected from the DEXs non-custodial model.

Some ERC-20 tokens on the Ethereum blockchain provide a DEX that operates similarly. Though some degree of decentralization is sacrificed, a DEX can provide a framework for parties to manage off-chain order books through smart contracts. Hosts can then access a larger liquidity pool and relay orders between traders. Once the parties are matched, the trade can be executed on-chain.

These models can be more advantageous for users than relying on slower on-chain order books. With less congestion and quicker confirmation times caused by primitive blockchain iterations, off-chain order books can provide faster speeds.

Automated Market Makers (AMM)

An automated market maker (AMM) reinvents order books with pricing algorithms that automatically price any asset pairing in real-time (e.g. Bitcoin-U.S. dollar).

Unlike traditional market-making, whereby firms provide an accurate price and a tight spread on an order book, AMMs decentralize this process and allow users to create a market on a blockchain. No counterparty is needed to make a trade, as the AMM simply interacts with a blockchain to “create” a market. Instead of transacting directly with another person, exchange, or market-maker, users trade with smart contracts and provide liquidity. Unfortunately, there are no order types on an AMM because prices are algorithmically determined, resulting in a sort of market order.

As with other DEX models, an on-chain transaction must occur to settle any trade. As opposed to some DEXs, AMMs tend to be relatively user-friendly and integrate with popular cryptocurrency wallets.

DEX Aggregators

DEX aggregators are precisely what they sound like: aggregators that compile various trading pools. Their main advantage is that they can increase liquidity for traders, particularly for those who are looking to expand their options or trade smaller tokens.

How these aggregators work is similar to a search engine, in that they compile and accumulate information and data from different exchanges to give users more options.

Tips for Using Decentralized Exchanges

Using a DEX has its advantages and risks. While you’re likely using a DEX for its advantages, it’s important to keep those risks in mind. Perhaps most importantly, remember that decentralized exchanges are, for all intents and purposes, operating off the radar and outside of regulatory authorities.

Also remember that as the popularity of DeFi as a whole grows, so too will the use of DEXs, and their features and functions. These are changing platforms and technologies, so do some research to make sure you know what you’re doing, and that you’re keeping your keys, phrases, and assets safe.

Pros of Decentralized Exchanges

There are many reasons fans and followers of crypto have embraced decentralized exchanges. These are some of the pros of decentralized exchanges:

No KYC/AML or ID Verification

DEXs are trustless, meaning users’ funds, privacy, and limited personal data are well preserved. Decentralized exchange users can easily and securely access a DEX without needing to create an on-exchange account, undergo identity verification, or provide personal information.

No Counterparty Risk

Because users don’t have to transfer their assets to an exchange (or third party), decentralized exchanges can reduce risks of theft and loss of funds due to hacks. DEXs can also prevent price manipulation or fake trading volume, and allow users to maintain a degree of anonymity due to a lack of Know Your Customer (KYC) cryptocurrency rules and regulations.

All Tokens Can be Traded

With a DEX, users can trade new and obscure cryptocurrencies that may be difficult to exchange elsewhere. Typically, centralized exchanges only support a dozen or so projects, and most only support the most popular cryptocurrencies, making smaller and less popular tokens more difficult to trade, especially as those exchanges restrict users from other countries.

Reduced Security Risks

As mentioned, decentralized exchanges may be more secure than their centralized counterparts. That’s because no single entity is in charge of assets, and instead, smart contracts and decentralized applications (dApps) automate transactions. It’s all handled by users, in other words, making it very difficult for a hacker or bad actor to infiltrate a centralized pile of assets and steal them.

That said, a bad or poorly developed smart contract could cause issues, which is something to be aware of.

Utility in the Developing World

Many parts of the world lack basic financial services, nevermind access to the crypto markets. That’s another pro for DEXs, which can be used by individuals anywhere in the world regardless of financial infrastructure.

In fact, DEXs may be the most beneficial to users in the developing world, giving businesses a way to transact assets without the need for a third party, where those parties may not be available or willing to operate.

Cons of a Decentralized Exchange

While decentralized exchanges offer some groundbreaking benefits, they also come with a few drawbacks.

Specific Knowledge Is Required

There’s no getting around it: You’ll need to know what you’re doing, at least to a degree, to use a decentralized exchange. Centralized exchanges exist for a reason: They’re relatively easy to use, and handle most of the complicated stuff for users. But when using a DEX, it’s all on the user. There’s no hand-holding, and as such, you’ll want to be confident that you know the ropes before using a DEX.

Smart Contract Vulnerabilities

Another thing we previously mentioned is the fact that smart contracts may be poorly constructed, leading to problems on a DEX. A smart contract is only as smart as the person or entity that created it, and there’s no guarantee that it will work as hoped all of the time.

Smart contracts themselves are similar to bits of code or commands that automate a process, and if there’s an error in the smart contract, it could produce unanticipated results.

No Recovery Ability

Unlike centralized exchanges run by private companies with employees, DEXs fundamentally have no recovery ability for lost, stolen, or misplaced funds. Due to a lack of a KYC process or ability to cancel a transaction in the event of a compromised account or loss of private key, users are unable to recover data or be returned their assets.

As discussed, there is no support team or help hotline to notify of missing funds or a lost private key, as users themselves are in control of the process. Because all transactions are processed and stored in smart contracts on the blockchain without any owners or overseers, refunds are incompatible with the network’s model and users are generally unable to regain access to their assets.

Unvetted Token Listings

The crypto space is rife with scams and junk tokens, and given that there’s no central authority in a DEX, it’s relatively easy for some of those junk tokens or coins to find themselves in the listings. Put another way: There is little or no vetting process for what’s listed on a DEX (though it may differ from exchange to exchange). Making sure you’re not falling for a scam coin, then, is on the user.

Low Liquidity

Many traders prefer centralized services with a greater liquidity pool, choice of instruments, currency pairs, and order types. Decentralized exchanges usually have lower liquidity than centralized platforms because they are newer and smaller, with a smaller potential client base (since DEXs are more difficult to use than CEXs). Yet, paradoxically, they must also attract new users to generate more liquidity.

Limited Speed

Transactions take time to be checked and validated on a blockchain network, and the processing speed depends on the network’s miners or validators, not the exchange itself.

Limited Trading Functionality

Decentralized exchanges tend to focus on executing simple buy and sell orders. As such, users may find advanced trading functions such as stop losses, margin trading, and lending are unavailable on most DEXs.

Scalability Issues

DEXs have suffered from the same network congestion issues relating to scalability issues as their underlying blockchain networks like Ethereum. Ethereum’s first network iteration, like other blockchains, was built to function securely at a smaller scale before scaling solutions were later implemented. Though a transformative network upgrade designed with massive scalability solutions has been in development since 2018, DEXs remain subject to first-layer network transaction ceilings.

Challenges to DEX Adoption

With sophisticated technology, potentially fewer blockchain security risks, and the ability to self-custody funds, further adoption of decentralized exchanges seems likely. But DEXs, for the most part, remain out of the mainstream. Despite the launch and rise in popularity of numerous DEXs within the past few years, some factors may slow down adoption.

Many investors may lack awareness surrounding:

• The security risks of centralized exchanges

• Self-custody as a security option

• How to securely self-custody funds (managing private keys)

• The existence of decentralized exchanges

• The advantages of decentralized exchanges

DEXs also present a few technical barriers to entry:

• Not user-friendly enough

• Network congestion during periods of high volume

• Transactions on current network iterations take time to be validated on blockchains

• High transactions fees during periods of high volume

• Users will only join a DEX with high liquidity

• Cross-chain interoperability must exist for DeFi platforms to interact with each other

• The need for fiat on-ramps and less volatile token prices

The Takeaway

Decentralized exchanges are a trustless solution that allows users to buy and sell cryptocurrency without roping in a third party. Though full decentralization is not yet a reality, different types of DEXs provide varying levels of security, privacy, and efficiency from which crypto traders can choose.

As DEXs continue to develop, evolve, and become more practical for users, user adoption may become a focal point as DEXs look to offer greater liquidity. The good news is that DEXs present only one of numerous ways to get involved in the crypto space.

FAQ

How do DEX fees work?

A DEX facilitates peer-to-peer trading, and levies network fees in order to facilitate those transactions. While fees from DEX to DEX may vary, they differ from centralized exchanges, which may charge trading fees or commissions for executing transactions.

What’s the difference between a decentralized exchange (DEX) and a centralized exchange (CEX)?

A decentralized exchange allows individual users to connect and transact assets without a third party. A centralized exchange, conversely, acts as a third party and takes custody of funds or assets during the transaction. The key difference is that a CEX acts as a central authority.

Are decentralized exchanges legal?

Yes, DEXs are legal, though they do operate in something of a gray area (like most of the crypto space) in that they’re unregulated by a central government authority. Some exchanges may be illegal in certain jurisdictions, too. That may change in the future, though, as regulators outline plans and potential rules for the crypto space.

How can I create a decentralized exchange?

If you want to create your own DEX, you’ll need a lot of background knowledge involving blockchain architecture and more. You would need to know how to code, identify key features that your DEX would have, and much, much more. You’re likely better off using an existing DEX, rather than creating one from scratch.

What Is Gamma in Options Trading?

By Laurel Tincher | Growing Wealth, invest, Investing, Terminology | Comments Off

Gamma is one of the indicators that comprise the Greeks, a model for pricing options contracts and discerning their risks. Traders, analysts, portfolio managers, and other investment professionals use gamma — along with delta, theta, and vega — to quantify various factors in options markets. Gamma expresses the rate of change of an option’s delta, based on a $1 price movement — or, one-point movement — of the option’s underlying security. You might think of delta as an option’s speed, and gamma as its acceleration rate.

Understanding Gamma

In the Greeks, gamma is an important metric for pricing options contracts. Gamma can show traders how much the delta — another Greeks metric — will change concurrent with price changes in an option’s underlying security. An option’s delta is relevant for short amounts of time only. An option’s gamma offers a clearer picture of where the contract is headed going forward.

Expressed as a percentage, gamma measures an option’s, or another derivative’s, value relative to its underlying asset. As an options contract approaches its expiration date, the gamma of an at-the-money option increases; but the gamma of an in-the-money or out-of-the-money option decreases. Gamma can help traders gauge the rate of an option’s price movement relative to how close the underlying security’s price is to the option’s strike price. Put another way, when the price of the underlying asset is closest to the option’s strike price, then gamma is at its highest rate. The further out-of-the-money a security goes, the lower the gamma rate is — sometimes nearly to zero. As gamma decreases, alpha also decreases. Gamma is always changing, in concert with the price changes of an option’s underlying asset.

Gamma is the first derivative of delta and the second derivative of an option contract’s price. Some professional investors want even more precise calculations of options price movements, so they use a third-order derivative called “color” to measure gamma’s rate of change.

Calculating Gamma

Calculating gamma precisely is complex and requires sophisticated spreadsheets or financial software. Analysts usually calculate gamma and the other Greeks in real-time and publish the results to traders at brokerage firms. Below is an example of how to calculate the approximate value of gamma. The equation is the difference in delta divided by the change in the underlying security’s price.

Gamma Formula

Gamma = Difference in delta / change in underlying security’s price

Gamma = (D1 – D2) / (P1 – P2)

Where D1 is the first delta, D2 is the second delta, P1 is the first price of the underlying security, and P2 is the second price of the security.

Example of Gamma

For example, suppose there is an options contract with a delta of 0.5 and a gamma of 0.1, or 10%. The underlying stock associated with the option is currently trading at $10 per share. If the stock increases to $11, the delta would increase to 0.6; and if the stock price decreases to $9, then the delta would decrease to 0.4. In other words, for every 10% that the stock moves up or down, the delta changes by 10%. If the delta is 0.5 and the stock price increases by $1, the option’s value would rise by $0.50. As the value of delta changes, analysts use the difference between two delta values to calculate the value of gamma.

Using Gamma in Options Trading

Gamma is a key risk-management tool. By figuring out the stability of delta, traders can use gamma to gauge the risk in trading options. Gamma can help investors discern what will happen to the value of delta as the underlying security’s price changes. Based on gamma’s calculated value, investors can see any potential risk involved in their current options holdings; then decide how they want to invest in options contracts. If gamma is positive when the underlying security increases in value in a long call, then delta will become more positive. When the security decreases in value, then delta will become less positive. In a long put, delta will decrease if the security decreases in value; and delta will increase if the security increases in value.

Traders use a delta hedge strategy to maintain a hedge over a wider security price range with a lower gamma.

Gamma as an Options Hedging Strategy

Hedging strategies can help professional investors reduce the risk of an asset’s adverse price movements. Gamma can help traders discern which securities to purchase by revealing the options with the most potential to offset loses in their existing portfolio. In gamma hedging, the goal is to keep delta constant throughout an investor’s entire portfolio of stocks and options. If any of their assets are at risk of making strong negative moves, investors could purchase other options to hedge against that risk, especially when close to options’ expiration dates.

In gamma hedging, investors generally purchase options that oppose the ones they already own in order to create a balanced portfolio. For example, if an investor already holds many call options, they might purchase some put options to hedge against the risk of price drops. Or, an investor might sell some call options at a strike price that’s different from that of their existing options.

Benefits of Gamma for Long Options

Gamma in options Greeks is popular among investors in long options. All long options, both calls and puts, have a positive gamma that is usually between 0 and 1, and all short options have a negative gamma between 0 and -1. A higher gamma value shows that delta might change significantly even if the underlying security only changes a small amount. Higher gamma means the option is sensitive to movements in the underlying security’s price. For every $1 that the underlying asset increases, the gamma rate increases profits. With every $1 that the asset increases, the investor’s returns increase more efficiently.

When delta is 0 at the contract’s expiration, gamma is also 0 because the option is worthless if the current market price is better than the option’s strike price. If delta is 1 or -1 then the strike price is better than the market price, so the option is valuable.

Risks of Gamma for Short Options

While gamma can potentially benefit long options buyers, for short options sellers it can potentially pose risks. The gamma rate can accelerate losses for options sellers just as it accelerates gains for options buyers.

Another risk of gamma for option sellers is expiration risk. The closer an option gets to its expiration date, the less probable it is that the underlying asset will reach a strike price that is very much in-the-money — or out-of-the-money for option sellers. This probability curve becomes narrower, as does the delta distribution. The more gamma increases, the more theta — the cost of owning an options contract over time — decreases. Theta is a Greek that shows an option’s predicted rate of decline in value over time, until its expiration date.

For options buyers, this can mean greater returns, but for options sellers it can mean greater losses. The closer the expiration date, the more gamma increases for at-the-money options; and the more gamma decreases for options that are in- or out-of-the-money.

How Does Volatility Affect Gamma?

When a security has low volatility, options that are at-the-money have a high gamma and in- or out-of-the-money options have a very low gamma. This is because the options with low volatility have a low time value; their time value increases significantly when the underlying stock price gets closer to the strike price.

If a security has high volatility, gamma is generally similar and stable for all options, because the time value of the options is high. If the options get closer to the strike price, their time value doesn’t change very much, so gamma is low and stable.

What Is a Naked Call Options Strategy?

By Mike Zaccardi, CMT, CFA | Growing Wealth, invest, Investing | Comments Off

A naked call, or uncovered call, is an aggressive, high-risk option strategy. It occurs when an investor sells or writes call options for which they don’t own the underlying security. The seller is betting that the underlying stock price will not increase before the call’s expiration date.

It is safer for traders to sell calls on a stock they already own. This way, if the stock price increases sharply, the trader’s net position is hedged. A hedged position, in this example, means that as the stock value rises, the long-stock position grows while the short-call option position loses. This situation describes a “covered call” position, which is a much lower risk strategy.

Naked calls, on the other hand, are speculative trades. You keep the premium if the underlying asset is at or in the money at expiration, but you also have the potential for unlimited losses. Read on for more about what naked calls are, how they work, their risks and rewards, and more.

Understanding Naked Calls

When a trader sells or writes a call option, they are selling someone else the right to purchase shares in the underlying asset at the strike price. In exchange, they receive the option premium. While this immediately creates income for the option seller, it also opens them up to the risk that they will need to deliver shares in the underlying stock, should the option buyer decide to exercise.

For this reason, it is significantly less risky to use a “covered call strategy” or sell an option on an underlying asset that you own. In the case of stocks, a single option generally represents 100 shares, so the trader would want to own 100 shares for each option sold.

Trading naked calls, on the other hand, is among the more speculative options strategies. The term “naked” refers to a trade in which the option writer does not own the underlying asset. This is a neutral to bearish strategy in that the seller is betting the underlying stock price will not materially increase before the call option’s expiration date.

In both the naked and the covered scenarios, the option seller gets to collect the premium as income. However, selling a naked call requires a much lower capital commitment, since the seller is not also buying or owning the corresponding number of shares in the underlying stock. While this increases the potential return profile of the strategy, it opens the seller up to potentially unlimited losses on the downside.

How Do Naked Calls Work?

The maximum profit potential on a naked is equal to the premium for the option, but potential losses are limitless. In a scenario where the stock price has gone well above the strike price, and the buyer of the option chooses to exercise, the seller would need to purchase shares at the market price and sell them at the strike price. Hypothetically, a stock price has no upper limit, so these losses could become great. When writing a naked call, the “breakeven price” is the strike price plus the premium collected; a profit is made when the stock price is below the breakeven price.

Investing in naked calls requires discipline and a firm grasp on common options trading strategies.

Writing a Naked Call

While there are significant risks, the process of naked call writing is relatively easy. An individual enters an order to trade a call option, but instead of buying they enter a sell-to-open order. Once sold, the trader hopes the underlying stock moves sideways or declines in value.

So long as the shares do not rise quickly, and ultimately remain below the strike price at expiration, the naked call writer will keep the premium collected (also known as the credit). Unexpected good news or simply positive price momentum can send the stock price upward, leading to higher call option values.

On the most common stocks and exchange-traded funds (ETFs), there are dozens of option strike prices at various expiration dates. For this reason, a trader must make both a directional bet on the underlying stock price and a time-wager based on the expiration date. Keeping a close eye on implied volatility is important, too.

Closing Out a Naked Call

When the trader wants to exit the trade, they punch in a buy-to-close order on the short calls. Alternatively, a trader can buy shares of the underlying asset to offset the short call position.

Finally, user-friendly options trading is here.^*

Naked Call Example

Let’s say a trader wants to sell a naked call option on shares of XYZ. Let’s also assume the stock trades at $100 per share.

For our example, we will assume the trader sells a call option at the $110 strike price expiring three months from today. This option might have a premium, or cost, of $5. The call option is said to be “out of the money” since the strike price is above the underlying stock’s current price.

Thus, the option only has extrinsic value (also known as time value). This naked call example seeks to benefit from the option’s time decay, also known as its theta. At initiation, the trader sells to open, then collects the $5 premium per share.

The trade’s breakeven price is $115 ($110 strike price plus $5 premium). Jump ahead a month, and shares of XYZ have rallied to $110. The value of the $110 strike call option, now expiring in just 60 days, is worth $9 since the share price rose $10.

On the other hand, the option’s time value dropped modestly since the expiration date drew closer. After pocketing the $5 premium at the trade’s initiation, the trader effectively owes $9 back, resulting in a net loss on paper.

Fast-forward to the week of expiration: XYZ’s stock price has fallen to $100. The $110 call option with just a few days left until expiration – Friday, is worth just $0.50 of time value with no intrinsic value. The trader chooses to close the trade with a buy-to-close order to lock in that $0.50 price.

In summary, the trader collected the $5 premium at the onset of the trade, experienced paper losses when XYZ’s stock price rose, but then ended on the winning side of the ledger by expiration when the position closed. The traders realized a profit of $4.50 considering the $5 sell and $0.50 buy-back. The trader could have also allowed the option to potentially expire worthless, which could have netted a $5 profit.

Using Naked Calls

Trading naked calls sometimes appeals to new traders who do not fully grasp risk and return probabilities. The notion that you can make money simply if a stock price or ETF does not go up in value sounds great. The problem arises when the underlying security appreciates quickly.

A naked call writer might not have enough cash to close the position. For this reason, brokers often have margin requirements on traders seeking to sell naked calls. When an account’s margin depletes too far, the broker can issue a margin call requiring the trader to deposit more cash or assets.

In general, naked calls make the most sense for experienced traders who have a risk management strategy in place before engaging in this type of trade.

Risks and Rewards

The potential for unlimited losses makes naked call writing a risky strategy. The reward is straightforward — keeping the premium received at the onset of the trade. Here are the pros and cons of naked call option trading:

Pros	Cons
Potential profits from a flat or declining stock price	Unlimited loss potential
Allows theta to work in your favor	Reward limited to the premium collected
Generates income	Margin calls when the underlying appreciates

Naked Call Alternatives

A common alternative to selling a naked call is to simply own the stock then sell calls against that position. This technique is known as “covered call writing”. This is a safer alternative to risky naked calls, but the trader must have enough cash to purchase the necessary shares.

One options contract covers 100 shares, so purchasing 100 shares of XYZ at $100 per share requires $10,000 of capital, unless the investor makes use of margin trading.

Other complex options strategies can achieve results similar to naked call writing. Covered puts, covered calls, and bear call spreads are common alternatives to naked calls. Experienced options traders have strategies to manage their risk, but even sophisticated traders can become overconfident and make mistakes.

Selling naked puts is another alternative that takes a neutral to bullish outlook on the underlying. When selling naked puts, the trader’s loss potential is limited to the strike price (minus the premium collected) since the stock can only go to $0.

The Takeaway

A naked call strategy is a high-risk technique in which a trader seeks to profit from a declining or flat stock price. The maximum gain is the premium received while the risk is unlimited potential losses. As with all option trading strategies, traders need to understand the risks and benefits of selling naked calls.

What is Ripple XRP? Everything to Know for 2022

By SoFi Editors | Growing Wealth, invest, Investing, Terminology | Comments Off

Cryptocurrency is a fast-moving space with new technologies and names arising on a daily basis. One of the largest and more polarizing subjects in the space is Ripple XRP, a private-company-founded platform and cryptocurrency launched in 2012. It has gained notoriety for its unique founding, structure, and operations.

Ardent supporters back its real-world adoption and growth potential. Dissenters contend that because of many of these same factors, it’s philosophically misaligned with cryptocurrency ideals and fundamentals.

Despite these contentions, Ripple XRP has grown to become a household name in cryptocurrency. Here’s everything you need to know about this cryptocurrency, and how to invest in it.

What Is Ripple?

Ripple is both a currency-exchange system designed to allow fast and low-cost transactions, and a cryptocurrency in its own right. Ripple’s primary goal is to connect financial institutions, payment providers, and digital asset exchanges to provide faster and cheaper global payments.

Created in 2012 by Jed McCaleb and Chris Larsen, Ripple is perhaps better known for its open-source, peer-to-peer decentralized platform, RippleNet, which enables money to be transferred globally in any fiat or cryptocurrency denomination between financial institutions.

Ripple makes some improvements on common shortfalls associated with traditional banks. Transactions on the Ripple Network are settled in seconds even under the regular stress of millions of transactions. Compare this to banks’ wire transfers which typically can take days to weeks to complete and can cost anywhere from $15 to $30 or more if sending or receiving internationally. Fees on Ripple vary based on the transaction size but overall are minimal, with the minimum cost for a standard transaction at 0.00001 XRP.

Whereas top cryptocurrencies like Bitcoin, Ethereum, and Litecoin are designed to be used primarily by individuals, Ripple’s system is designed to be adopted by banks, funds, and institutions.

What Is XRP?

XRP is the currency issued and managed by Ripple (though users can also create their own currency on the platform). Ripple began selling XRP in 2012 to fund company operations, allowing its users to buy cryptocurrency, though it has taken a backseat to the company’s primary objective of developing RippleNet.

Throughout Ripple’s lifespan, leadership has reframed how XRP fits into the company’s business model, originally proclaiming it as the fuel on which its borderless payments technology runs, and later as a more efficient medium of exchange than Bitcoin.

XRP tokens represent the transfer of value across the Ripple network and can be traded on the open cryptocurrency market by anyone. Unlike Bitcoin’s popular store-of-value narrative use-case, XRP is primarily used for payments and borderless currency exchange. While Ripple’s centralized infrastructure concerns some in the cryptocurrency space, its fast transaction speeds, low transaction costs, and low energy usage provide superior performance as a medium of exchange compared to many blockchain-based cryptocurrencies.

What is the XRP Price?

At the time of reporting, the XRP price is $0.474494. It’s all-time high was $3.8419 in January 2018. It went as low as $.0041 in November 2015.

How Does Ripple Work?

There are two main technologies to be aware of when it comes to Ripple and XRP. Specifically, the XRP ledger (XRPL) and the Ripple Protocol Consensus Algorithm (RPCA). Here’s how they work.

XRP Ledger (XRPL)

RippleNet is built on top of its own blockchain-like distributed ledger database, XRP Ledger (XRPL), which stores accounting information of network participants and matches exchanges among multiple currency pairs. The transaction ledger is maintained by a committee of validators who act like miners and full-node operators to reach consensus in three to five seconds—versus Bitcoin’s 10 minutes. Because there are no miners competing to confirm transactions for block rewards, validators verify transactions for no monetary reward.

Anyone can become an XRP validator, but in order to gain trust and be used by others on the network, validators must make Ripple’s unique node list (UNL), deeming them a trusted Ripple validator. These centralized validators are critical to prevent double-spending and censorship of transactions. There are only 35 active XRP validators; six are run by Ripple.

Ripple Protocol Consensus Algorithm (RPCA)

XRP’s design is predicated on speed and cost, as opposed to decentralization. Unlike different types of cryptocurrency like Bitcoin and Ethereum, which are built on the blockchain and validated by miners through the Proof of Work consensus mechanism, Ripple confirms transactions through its own consensus mechanism, the Ripple Protocol Consensus Algorithm (RPCA).

By avoiding Proof of Work’s energy-intensive mining, Ripple transactions require less energy than Bitcoin or Ethereum, are confirmed faster, and cost less. However, this speed is ultimately achieved because of XRP’s centralized infrastructure, which some argue makes the network less secure, censorship-resistant, and permissionless than open-source blockchain networks.

Ripple Cryptocurrency Token Supply

Unlike many other cryptocurrencies, XRP is not mined. The token’s entire supply was created when the network first launched in 2012 and Ripple executives intermittently tap into an escrow to release segments of the supply to sell on the open market.

In other words, unlike Bitcoin’s decentralized economy, XRP’s supply and issuance is centralized and governed by a few authorities. Because the total supply already exists, no more will be created into existence, thus making XRP fixed in quantity and not inflationary.

As of January 2021, only 45 billion XRP tokens are in circulation, out of the maximum total 100 billion. Due to the vast circulating supply, XRP has had one of the largest market caps of any cryptocurrency, even briefly eclipsing that of Ethereum’s second-largest cap late in the 2017-2018 bull market.

Ripple Crypto and Regulatory Trouble

In late 2020, Ripple became the target of an SEC investigation . The regulatory body determined that Ripple Labs Inc. and two of its executives, Co-Founder Chris Larsen and CEO Bradley Garlinghouse, had raised over $1.3 billion through an “unregistered, ongoing digital asset securities offering” to finance the company’s operations. Consistent with recent cryptocurrency rules set by the SEC, Ripple’s leaders were charged with unlawful issuance of securities in the form of sales of its XRP token, raising questions about compliance with cryptocurrency taxes.

The XRP price crashed amid the fallout, from over $0.60 to under $0.30, as prominent crypto exchanges began delisting the token and Ripple executives, including Founder Jed McCaleb, sold off personal XRP holdings worth millions.

Is Ripple a Good Investment?

Though XRP has been impacted by Ripple’s legal blow, XRP is an independent token that can and does function somewhat outside of Ripple’s business model. The crash in price and soured fundamental outlook may not paint a bright picture of XRP as an investment to some. Whether XRP recovers and continues to evolve with the rest of the crypto herd remains to be seen, but as investors look for value in undervalued assets, it doesn’t hurt to do further research and form an educated conclusion.

Pros and Cons of Ripple XRP

Because Ripple is different in some ways from other cryptocurrencies, it makes sense to review its perceived pros and cons before making any investing decisions.

Pros of Ripple XRP

•  Fast speeds
•  Low fees
•  Interest/tentative adoption by financial institutions

Cons of Ripple XRP

•  Centralized infrastructure, governance, issuance
•  Corruptible validators
•  Unsupported by many exchanges

How to Invest in XRP

To start investing in Ripple, you first need to join a crypto exchange. Signing up for an account could include different verification processes, depending on the exchange. Once you’re signed up, you’re ready to trade or buy Ripple XRP. You can trade any current crypto you own, or you can buy a major cryptocurrency like Bitcoin or Ethereum and then use that to buy Ripple XRP.

The Takeaway

Ripple XRP is a global digital payments system that sacrifices decentralization for performance. The network and technology is owned and at least partly run by Ripple, the private company, which controls the underlying infrastructure, supply, and some of the limited network validators. While Ripple strays from the conventional decentralization model adopted by leading cryptos Bitcoin and Ethereum, it conforms to some degree through its own specially — designed infrastructure.

Although Ripple’s primary goal is providing a borderless payments and currency exchange gateway for financial institutions, its native cryptocurrency XRP has taken on a life of its own and is actively traded and analyzed by investors. With high-ranking metrics such as fast and inexpensive transactions, some investors argue XRP is a strong competitor to large cryptocurrency blockchains such as Bitcoin and Ethereum. Conversely, Ripple XRP’s centralization has been a major philosophical and security concern for others — including US regulatory bodies.

Guide to Options Spreads: Definition & Types

By Samuel Becker | Growing Wealth, invest, Investing | Comments Off

Options spreads are multi-legged trading strategies used to limit risk while also capturing the potential for profits. Traders using an option spread simultaneously buy multiple options with the same underlying asset with different strike prices, different expiration dates, or both.

Understanding options spreads can help you decide whether these strategies will work for your portfolio, and which one to use in a given situation.

Credit and Debit Spreads

The difference between credit spread options and debit spreads is that an options trader sells one (credit), and buys the other (debit). When a trader sells an option, they receive a premium (a credit) to their account. Conversely, when they buy an option, they pay a premium to open the position, resulting in a debit to their account.

Recommended: What Investors Should Know About Spread

3 Common Option Spread Strategies

In options spread strategies, the trader buys and sells multiple options pegged to the same underlying asset or security. The type of options that the trader buys and sells are all of the same type (i.e., they’re all call options or put options), and they either have different strike prices or expiration dates.

There are several different types of option spreads. Here’s a look at a few common ones:

1. Vertical Spread Options

A vertical spread is an options strategy in which the options have the same expiration date but different strike prices. There are four types of vertical spread options that investors use depending on whether they are bullish or bearish and whether the spread is a debit or credit.

Bull Call Spreads

A bull call spread strategy involves buying a call option, and then also selling another call at a higher strike price. The call spread options have the same underlying asset and expiration date.

Investors using this bull spread options strategy anticipate an increase in the value of the underlying asset. With this strategy, a trader caps their potential losses to the net premium they paid for the options (essentially hedging their risk). Their maximum gain is capped at the differences in strike prices, minus the net premium paid.

For example, a trader buys a call option on Stock X at a strike price of $10, for a premium of $2. They also sell a call option with an identical expiration date at a strike price of $12, receiving a premium of $1. This is referred to as a “debit” spread, as the trader pays a net premium (of $1 in this case) to buy into their position.

Bear Call Spreads

The opposite of a bull call spread, a bear call spread benefits when the underlying asset’s value decreases. If we stick with Stock X from our previous example, a trader using a bear call spread would anticipate that Stock X’s value is going to decrease.

As such, the trader sets up the spread by selling a call option, and buying another call option at a higher strike price—the inverse of the bull call spread method. This is a “credit” spread,, so the trader can not gain more than the net premium the trader received for the position. Their potential loss is capped at the differences in strike prices.

Example: A trader sells a call option on Stock X at a strike price of $10, and buys another call at a strike price of $12.

Bull Put Spreads

A bull put spread is similar to a bull call spread, but it involves puts rather than calls. Using a bull put spread, a trader anticipates an increase in the underlying asset’s value. In our example, the trader would sell a put option at a strike price of $10, and simultaneously buy another at a lower strike price, say, $8.

The trader can not lose more than the difference between the strike prices or gain more than the premium received.

Bear Put Spreads

A bear put spread is the inverse of a bull put spread. In our example, the trader would buy one put option at a $10 strike price, and simultaneously sell another put at a lower strike price, like $8.

The trader can not lose more than the net premium the trader paid to take the position (again, because this is a “debit” spread) or gain more than the difference in strike prices.

2. Horizontal Spreads

Horizontal spreads (also called “calendar spread options”) involve options with the same underlying asset, the same strike prices, but different expiration dates. The main goal of this strategy is to generate income from the time decay effects, or volatility of the two options.

There are also two main types of horizontal spreads.

Call Horizontal Spreads

A call horizontal spread is a strategy which a trader would employ if they believe that the underlying asset’s price would hold steady. In this case, the trader would buy a call with an expiration date on January 15th, for example, and sell another call with a different expiration date, like January 30th.

The trader can also reverse these positions, by selling a call option that expires on January 15th, and selling another that expires on January 30th. The two positions with differing expiration dates act as buffers, reigning in potential losses (the premium paid) and gains.

Put Horizontal Spreads

Put horizontal spreads similar to call horizontal spreads, except that traders utilize puts instead of calls.

3. Diagonal Spreads

Finally, we have diagonal spreads, which incorporate elements from both vertical and horizontal spread strategies. That is, diagonal spreads involve the same option types and underlying asset (the same as before), but with differing strike prices and differing expiration dates.

Diagonal spreads—with different strike prices and expiration dates—allow for numerous combinations of options, making them a fairly advanced strategy. They can be bearish, and bullish for example, while also using calls or puts, with different time horizons (long or short).

Other Options Spreads

While we’ve covered the main types of options spread strategies, there are a few more you may run into.

Butterfly Spread Options

A butterfly spread incorporates multiple strike prices, and can utilize either calls or puts. It also combines a bull and bear spread across four different options.

An example would be a trader buying a call at a certain strike price, selling two more calls at a higher strike price, and then buying another call at yet an even higher strike price—of equal “distance,” or value, from the two central calls. This results in a cap on losses and gains, with the trader realizing gains depending on volatility levels of the underlying asset.

Box Spread Options

A box spread option strategy involves a bear put and a bull call with identical strike prices and expiration dates. Under very specific circumstances, traders can use the strategy to create profitable arbitrage opportunities.

The Takeaway

There are several different options spreads strategies that traders use to limit their losses and achieve potential gains based on their projections about the price of a specific asset. Options strategies can get complicated, but you don’t need to invest in derivatives in order to build a portfolio.
