Both brokerage accounts and cash management accounts (CMAs) are offered by brokerage firms and both have the potential to earn returns on your money. However, these accounts serve different purposes and work in different ways: Brokerage accounts are for investing in the market, while CMAs focus on managing cash with easy access and the ability to earn interest on your balance.

Here’s a closer look at brokerage accounts vs. cash management accounts to help you decide if you need one or the other, or both.

What Is a Cash Management Account?

A cash management account (CMA) is a type of cash account offered by brokerage firms that offers some of the same features as checking accounts and savings accounts. CMAs allow you to deposit money and earn interest. Most provide access to your money via debit cards, in addition to checks.

What Is a Brokerage Account?

A brokerage account allows customers to deposit money which can then be used to buy and sell investments such as stocks, bonds, mutual funds, exchange-traded funds (ETFs), and other securities.

There are three main types of brokerage firms.

•   A full-service brokerage firm usually provides a range of financial services including financial advice and automated investing.

•   A discount brokerage offers lower fees in exchange for fewer financial planning services.

•   Online brokerages allow you to trade via the internet and often charge the lowest fees.

Similarities Between a Cash Management Account and Brokerage Account

Although brokerage and CMA accounts work in different ways, there are some similarities.

Both Offered by Brokerages

Both types of accounts are offered by brokerage firms. When you open a brokerage account and link it to a CMA at the same firm, it can provide a convenient way to transfer assets from one account to another when you buy and sell securities.

The Potential to Earn Returns

When considering a brokerage account vs. a cash management, remember that they both offer customers the potential to earn money on investments or deposits, respectively.

In a brokerage account, you have the potential to earn returns from your investments, although you also face the risk of loss that comes with investing in stocks, bonds, and other securities.

A cash management account is generally a safer place to keep your money and you’ll earn interest on your deposits. But those rates are generally lower than the gains you might see from other investments.

Brokerage Account vs Cash Management: What Are the Differences?

Cash management accounts and brokerage accounts work in different ways. CMAs mirror traditional savings and checking accounts and brokerage accounts are strictly for investments. Here are the details:

Earnings Come From Different Places

In a brokerage account, potential earnings come from the gains you might see when investing in stocks, bonds, and other investments. Investing in securities also comes with the risk of losses.

Earnings in cash management accounts come from the interest rate paid on your balance. Usually, these rates are similar to the rates paid in traditional savings accounts.

CMAs also act like checking accounts because you can use checks or a debit card for purchases. But traditional checking accounts don’t usually pay interest, or if they do the rate is often lower than a CMA.

Earnings on Brokerage Accounts Are Potentially Higher Over Time

Over the long term, investing has historically provided higher returns than savings accounts. With those potential earnings comes market risk, meaning you may experience losses too, especially in the short-term.

To manage a brokerage account or work with a broker, you need to take into account your tolerance for market risk and what combination of stocks and bonds is right for your financial goals.

Insurance Is Provided by Different Sources

When you open a new bank account, up to $250,000 of your cash deposits are typically covered by the Federal Deposit Insurance Corporation (FDIC) in the unlikely event of bank failure. The $250,000 limit is per depositor, per insured bank, for each account ownership category.

Most brokerage accounts, however, are insured by the Securities Investor Protection Corporation (SIPC) in the event of theft, fraud, or if the brokerage fails. The SIPC offers up to $500,000 of coverage total, per person, if such a loss were to occur. The SIPC does not cover investment losses.

Cash management accounts have so-called sweep accounts, which are insured by the FDIC. Here’s how it works: CMAs sweep funds into a variety of FDIC-insured banks. If you make a $200,000 deposit, for example, your money may be split into four $50,000 deposits in four different bank accounts. (The CMA provider manages this process — you only see your total CMA balance.)

Before your money is moved into the different accounts, your deposit is protected by SIPC insurance if the brokerage is an SIPC member.

What Money in These Accounts Can Be Used for

Because CMA accounts typically offer checks and/or debit cards, you can use that money for purchases or bill paying or ATM withdrawals.

Money kept in a brokerage account is strictly used for trading securities. But by linking a CMA to your brokerage account, you can easily transfer cash from one to the other, for investing purposes.

The Takeaway

When considering a brokerage account vs. cash management, it helps to know what makes these accounts different, and how they can work together. While a brokerage account is for trading securities, and comes with the risks associated with investing in securities, a cash management account (CMA) is similar to a traditional checking or savings account. There’s almost no risk of losing money, and your deposits can earn interest. Because both are offered at brokerage firms, you can have both, and use your cash management account as a place to keep funds you don’t wish to invest.

Or, as an alternative to a cash management account, you might consider keeping your extra cash in a high-yield savings account. This is a type of federally insured savings product offered by banks and credit unions that typically earns a much higher rate than a regular savings account.

FAQ

Are brokerage accounts and cash management accounts the same?

No. Brokerage accounts are used to buy and sell securities. Cash management accounts act more like traditional bank savings and checking accounts, but are provided by brokerage and other non-bank financial institutions. Sometimes the accounts may be linked. However, the accounts earn money from different sources.

Can you keep cash in a brokerage account?

Yes, you can deposit and keep cash in a brokerage account. However, money in a brokerage account is strictly for investing in stocks, bonds, funds and other securities. If you’re just looking to store cash and earn interest, you’re likely better off with a cash management account, money market account, or high-yield savings account.

Do cash management accounts and brokerage accounts work together?

Generally, yes. If you have a cash management account (CMA) and a brokerage account at the same brokerage firm and the accounts are linked, you can use your CMA to move cash into your brokerage account in order to execute trades. You can also transfer the money from sales of securities into your CMA for safekeeping. The combination gives you the ability to purchase stocks, bonds, mutual funds and other securities, but also offers the flexibility, liquidity, and interest earnings of traditional bank accounts.

SOBNK-Q125-057

Options are derivative financial instruments that give buyers the right (but not the obligation) to buy or sell an underlying security, such as a stock, at a predetermined price (the strike price) within a set time frame. The price of an option, known as the premium, is determined by factors like the underlying asset’s market price, intrinsic value, time until expiration, and volatility.

Understanding how options are priced can help investors decide when to enter or exit a trade, manage risk, or evaluate potential returns.

How Is an Option Price Determined?

There are two main types of options: call options and put options. An investor who buys a call option acquires the right to buy the underlying asset at the strike price price, while, conversely, an investor who buys a put option acquires the right to sell the option’s underlying asset at the strike price.

Options traders analysts take many factors into account to determine the price, or premium, of call options and put options. The most widely known method for determining the value of an option is the Black-Scholes model. But other models — such as the binomial and trinomial options pricing models — are more commonly used to determine stock option prices.

All of those options pricing models are complex, but they all draw on a few primary factors that drive the investment value of an options contract:

• The market price of the stock that underlies the option

• The current intrinsic value of the option

• The time until the option expires

• Volatility

Market Price and Intrinsic Value

Market price first is easy to understand — it’s the price at which the underlying stock is trading. The second factor — the intrinsic value of the option — is the value of the option would be worth if sold at that moment. This only applies if the price of the underlying stock has moved to where the option is “in the money,” meaning the owner of the option would make a profit by exercising it.

Time Value

The time until expiration is more complex. This so-called time value reflects the amount of time before expiration of a contract in options trading. It represents the possibility that an out-of-the-money option could eventually become profitable.

It’s the one part of an option’s value that only goes down — and which goes at an increasingly rapid rate as the options contract approaches expiration. As the expiration date approaches, larger price movements in the underlying stock are required to create significant changes in the option’s price.

Volatility

Time value reflects the potential for price movement from the underlying asset, influenced by factors such as volatility and market expectations of future price fluctuations. As a general rule, stocks with a history of high volatility underlie options with a higher likelihood to be in-the-money at the time of their expiration.

Volatility, in many pricing models, is represented by a measure of price fluctuations of the underlying asset. Beta, on the other hand, measures the asset’s volatility versus the volatility of the overall market. Options on stocks with higher historic or expected volatility typically cost more than options contracts on stocks that have little reputation for dramatic price swings.

What Are the Different Option Pricing Models?

There are several models that investors and day traders consider when figuring out how to price an option. Here’s a look at a few of the most common:

The Black-Scholes Merton (BSM) Model

The best-known options pricing method is the Black-Scholes model. The model consists of a mathematical formula that can be daunting for people without a math background. That’s why both institutional and retail investors employ online options calculators and analysis tools.

The economists who created the formula published their findings in 1973, and won the 1997 Nobel Prize in economics for this new method for arriving at the value of financial derivatives.

Also known as the Black-Scholes Merton (BSM) model, the Black-Scholes equation takes the following into account:

• The underlying stock’s price

• The option’s strike price

• Current interest rates

• The option’s time to expiration

• The underlying stock’s volatility

In its pure form, the Black-Scholes model only works for European options, which investors can not exercise until their expiration date. The model doesn’t work for U.S. options, because U.S. options can be exercised before their expiration date.

The Binomial Option Pricing Model

The binomial option pricing model is less well-known outside of financial circles, but it’s more widely used. One reason it’s more popular than the Black-Scholes Model is that it can work for U.S. options. Invented in 1979, the binomial is based on the assumption that, in any pricing scenario, an underlying asset’s price will move either up or down. As a method for calculating an option’s value, the binomial pricing model uses the same basic data inputs, such as the underlying asset’s price, strike price, time to expiration, the interest rate, and volatility, and its equation may be updated as new information emerges.

In comparison with other models, the binomial option pricing model is very simple at first, but it becomes more complex as investors take multiple time periods into account. For a U.S. option, which the owner can exercise at any point before it expires, traders often use the binomial model to decide when to exercise the option.

By using the binomial option pricing model with multiple periods of time, the trader has the advantage of being able to better visualize the change in the price of the underlying asset over time, and then evaluate the option at each point in time. It also allows the trader to update those multi-period equations based on each day’s price movements and emerging market news.

The Trinomial Option Pricing Model

The trinomial option pricing model is similar to the binomial model but it allows for three possible outcomes for an option’s underlying asset within a given period. Its value can go up, go down, or stay the same. As they do with the binomial model, traders recalculate the trinomial pricing model over the course of an option’s life, as the factors that drive the option’s price change, and as new information comes to light.

Its simplicity and acknowledgement of a static price possibility makes it more widely used than the binomial option pricing model. When pricing exotic options, or any complex option with features that make it harder to calculate than the common calls and puts on an exchange, many investors favor the trinomial model as a more stable and accurate way of understanding what the price of the option should be.

The Takeaway

Options pricing isn’t just about a single number — it’s the result of multiple factors, from market price and volatility to the passage of time. Investors rely on models like Black-Scholes, binomial, and trinomial pricing to estimate an option’s value, each offering different insights depending on the type of contract.

Although these calculations can seem complex, the core idea remains the same: an option’s price reflects both current conditions and future possibilities. Understanding these mechanics can help traders make more informed decisions, whether they’re managing risk or seeking new opportunities in the market.
