Momentum trading is a type of short-term, high-risk trading strategy that requires a lot of skill and practice. While momentum trades can be held for longer periods when trends continue, the term generally refers to trades that are held for a day or several days, on average.

Momentum traders strive to chase the market by identifying the trend in price action of a specific security and extract profit by predicting its near-term future movement.

Looking for a good entry point when prices fall and then determining a profitable exit point when prices become overbought is the method to momentum trading madness. Momentum trading can also involve using various short strategies to profit from market downturns.

In a sense, this kind of trading is that simple. But of course, things can be much more difficult in practice. If it were easy, then everyone would do it.

The fact of the matter is this—the vast majority of individuals who attempt short-term trading strategies like this are not successful.

History of Momentum Trading

Momentum trading is a relatively new phenomenon. This kind of trading style has been made much more readily accessible with modern technology that makes trading easier in general.

An investor named Richard Driehaus has sometimes been referred to as “the father of momentum trading.” His strategy was at odds with the old stock market mantra of “buy low, sell high.”

Driehaus theorized that more money could be made by buying high and then selling at even higher prices. This idea aligns with the overarching theme of following a trend.

During the late 2000s as computers got faster, many different varieties of this type of trading began to spring up. Some of them were driven by computer models, sometimes trading on very small timeframes.

High-frequency trading algorithms, for example, can execute hundreds of trades per second. With this type of trading, humans don’t actually do anything beyond managing the system. It’s believed that about 90% of all trades that occur on Wall Street today are executed by high-frequency trading bots.

Momentum trading has become more popular in recent years with the advent of digital brokerage accounts. There have also been a number of new investment vehicles created that are well-suited to this style of trading, such as certain exchange-traded funds (ETFs).

Ever since the widespread elimination of many commission fees back in Q4 2019, it’s possible that even more retail investors might be inclined to try their hand at momentum trading. Transaction costs and brokerage fees were also a very big disadvantage for short-term traders, as the fees could reduce profits by a wide margin.

Why are some people interested in this kind of trading? The answer is simple.

While the risks are high, so are the potential rewards.

How Momentum Trading Works

In essence, momentum trading involves picking a security (such as a stock or ETF), identifying a trend, and then executing a plan to capitalize on the trend based on the assumption that it will continue in the near-term.

There are many things that can be taken into consideration to this end. Among these are factors like volatility, volume, time, and technical indicators.

Volatility

Volatility refers to the size and frequency of price changes in a particular asset. Short-term traders tend to like volatility because wild market swings can create opportunities for large profits in short amounts of time. Of course, volatility also increases risk. In fact, one of the biggest indications that an asset has high risk is often that it has high volatility.

Volume

Volume represents the quantity of units of a particular asset being sold and bought during a certain period (e.g., the number of shares of a stock or ETF). Traders need assets with adequate volume to keep their trades profitable. Without enough volume, traders can fall victim to something known as slippage.

Slippage occurs when there aren’t enough shares being sold at a trader’s price point to fulfill the order all at once. A trade then winds up being executed across multiple orders, each of them being slightly lower than the last, resulting in a smaller profit overall. When volume is high enough, this won’t happen, as most orders can be filled all at once at a single price point.

Time Frame

Having a plan is part of what separates successful traders from unsuccessful ones. As discussed, momentum trading usually takes place on a short time-frame, although not always as short as some day trading strategies. While day traders might hold a position for hours or even minutes, momentum traders might hold positions for a day, several days, or longer.

Technical Indicators

Technical analysis is the art of trying to predict future price movements by analyzing charts. Charting software provides traders with a long list of tools that use different mathematical formulas to indicate how the price of an asset has performed in a specific timeframe. These tools are referred to as technical indicators.

Based on one or more of these indicators, traders try to infer what the near future holds for a security. This process is far from perfect, and technical analysis might best be described as only slightly predictive. Still, it’s an important part of a short-term trader’s arsenal. What do these indicators look like?

One of the simplest technical indicators is called the Relative Strength Index (RSI). This indicator is supposed to chart the recent strength of a stock based on closing prices during a given period.

The RSI provides a simple numerical value on a scale from 0–100. The higher the value, the more overbought a security might be, while a lower value indicates a security might be oversold. In other words, a low RSI can be a buy signal, while a high RSI can be a sell signal.

The topic of technical analysis goes far beyond the scope of what can be covered here in this article. For a more detailed look at the subject, take a look at this SoFi resource.

Advantages of Momentum Trading

The main advantage of momentum trading is that it can be profitable in a relatively short amount of time when executed correctly and consistently.

Whereas buy-and-hold investors tend to wait months, years, or even decades before seeing significant profits, successful momentum traders have the potential to turn out profits on a weekly or daily basis.

While investing for the long-term requires a good understanding of the fundamental factors that go into each investment, momentum trading tends to be focused around technical analysis of charts.

While this method of trying to predict price movements is by no means infallible, it does keep things simple. Traders are focused through a single lens rather than trying to comprehend the bigger picture.

In this sense, momentum trading may be simpler. But compared to long-term investing, short-term trading involves a lot more buying and selling, and that creates additional opportunities to make mistakes.

Disadvantages of Momentum Trading

As mentioned, there are a lot of risks involved in momentum trading. Momentum traders try to make inferences about future price movement based on the recent actions of other market participants. This can work, but it can also be thrown off balance completely by a single press release or fundamental development.

For example, imagine a momentum trader identifies a strong upward trend in a stock of a telecommunications company we will call Company A.

This imaginary trader develops a plan and begins executing it, placing a buy order at a select price point when the stock dips. The plan is to sell once the stock reaches a long-term resistance level that was established months ago, let’s say.

Our hypothetical trader has done this same trade before many times and made a nice profit each time, so she thinks this time will be no different.

But then something unexpected happens. The next trading day, when profits were to be booked on a continued rising price trend, a rival telecommunications company, Company B, issues a press release.

Company B has pulled ahead of Company A, implementing a new technology that will benefit customers greatly. As a result, investors begin selling stock in company A, expecting them to lose customers to competitors like Company B.

In this imaginary case, any trends that might have been identified using technical analysis would have been invalidated quickly. Hypothetical scenarios like this play out every day in the real markets.

Tax Implications to Know

Those interested in momentum trading or other short-term trading strategies may want to review the tax implications associated with this style of trading. It can be worth reviewing how taxes will impact an investor, since they could take a chunk of an investor’s profits.

Know that the IRS makes a distinction between traders and investors, for tax purposes, and it’s important to understand where you fall. A trader is someone considered by law to be in the investment business while an investor is someone buying and selling securities for personal gain.

The IRS also differentiations between short-term and long-term investments when evaluating capital gains and losses. In general, long-term investments are those held for a year or more, while those held for less than a year are considered short-term investments. Long-term investments may benefit from a lower tax rate, while short-term capital gains are taxed at the same rate as ordinary income.

Another rule worth understanding is the wash sale rule . While some capital losses can be taken as a tax deduction, there are certain regulations in place to stop investors from taking advantage of this benefit. The wash sale rule restricts investors from benefiting from selling a security at a loss and then buying a substantially identical security within 30 days. A wash sale occurs if you sell a security and then your spouse or a corporation under our control buys a similar security within the 30 day period following the sale.

Fractional shares are a useful way to allow new investors to get their feet wet by investing small amounts of money into parts of a share of stock. For some investors, fractional shares are worth it because it means they can own a part of a stock from a company they are interested in, without committing to buying a whole share.

While fractional shares have much in common with whole shares, they don’t trade on the open market as a standalone product. Because of that, fractional shares must be sold through a major brokerage.

What Does It Mean to Buy Fractional Shares?

A fractional share is less than one whole equity share (e.g. 0.34 shares). Fractional shares appreciate or depreciate at the same rate as whole shares, and distribute dividends at the same yield proportionate to the fractional amount.

Fractional shares were previously only available to institutional investors at one-sixteenth intervals, but have recently become widely available to retail investors at exact decimals (in order to increase market pricing precision and lower trading costs).

This new capability offers another layer of financial inclusion to casual investors by lowering minimum investing requirements to thousands of stocks and assets and making them available in smaller quantities. According to Gallup, 45% of all Americans have no stock investments—but fractional shares provide an increasingly lower barrier to investing than in previous generations.

Why Fractional Shares Are Worth Buying

For some investors, these positives make buying fractional shares worth it.

Access to Unaffordable Stocks

Fractional shares can help build a portfolio made of select stocks, some of which may be too expensive for some investors to afford one whole share. With fractional shares, an investor can choose stocks based on more than just price per share.

Previously, new investors would face price discrimination for not having enough funds to buy one whole share. But with fractional shares, an investor with $1,000 to spend who wants to buy a stock that costs $2,000 per share, can buy 0.5 shares of that stock.

Fractional shares make it easier to spread a modest investment amount across a variety of stocks. Over time, it may be possible to buy more of each stock to total one or more whole shares. In the meantime, buying a fractional share allows an investor to immediately benefit from a stock’s gain, begin the countdown to qualify for long-term capital gains (if applicable), and receive dividends.

A Doorway to Investing

History has shown that the stock market typically outperforms fixed-income assets and interest-bearing savings accounts by a wide margin. If equities continue to provide returns comparable to the long-term average of 7%, even a small investment can outperform money market savings accounts, which typically yield 1-2%. (Though as always, it’s important to remember that past performance does not guarantee future success.)

By utilizing fractional shares, beginners can make small investments in the stock market with significantly more growth potential even with average market returns versus savings accounts that typically don’t even match inflation.

Maximized Dollar-Cost Averaging

Fractional shares help maximize dollar-cost averaging, in which investors invest a fixed amount of money at regular intervals.

Because stock shares trade at precise amounts down to the second decimal, it’s rare for flat investment amounts to buy perfectly-even amounts of shares. With fractional shares, the full investment amount can be invested down to the last cent.

For example, if an investor contributes $500 monthly to a mutual fund with shares each worth $30, they would receive 16.66 shares. This process then repeats next month and the same investment amount is used to purchase the maximum number of shares, with both new and old fractional shares pooled together to form a whole share whenever possible.

Maximized Dividend Reinvestment Plans

This same scenario applies to dividend reinvestment plans (also known as DRIP investing). In smaller dividend investment accounts, initial dividends received may be too small to afford one whole share. With fractional shares, the marginal dividend amount can be reinvested no matter how small the amount.

Fractional shares can be an important component in a dividend reinvestment strategy because of the power of compounding interest. If an investor automatically invests $500 per month at $30 per share but can’t buy fractional shares, only $480 of $500 can be invested that month, forfeiting the opportunity to buy 0.66 shares. While this doesn’t seem like much, not investing that extra $20 every month can diminish both investment gains and dividends over time.

Stock Splits

Stock splits occur when a company reduces its stock price by proportionately issuing more shares to shareholders at a reduced price. This process doesn’t affect the total value of an investment in the stock, but rather how the value is calculated.

For some investors, a stock split may cause a split of existing shares resulting in fractional shares. For example, if an investor owns 11 shares of a company stock worth $30 and that company undergoes a two-for-three stock split, the 15 shares would increase to 22.5 but each share’s price would decrease from $30 to $20. In this scenario, the stock split results in the same total of $450 but generated a fractional share.

Mergers or Acquisitions

If two (or more) companies merge, they often combine stocks using a predetermined ratio that may produce fractional shares. This ratio can be imprecise and generate fractional shares depending on how many shares a shareholder owns. Alternatively, shareholders are sometimes given the option of receiving cash in lieu of fractional shares following an impending stock split, merger, or acquisition.

Disadvantages of Buying Fractional Shares

Fractional shares can be a useful asset if permitted, but depending on where you buy them could have major implications on their value.

Order Type Limitations

Full stock shares are typically enabled for a variety of order types to accommodate different types of trading requests. However, depending on the brokerage, fractional shares can be limited to basic order types such as market buys and sells. This prevents an investor from setting limit orders to trigger at certain price conditions and from executing trades outside of regular market hours.

Transferability

Not all brokerages allow fractional shares to be transferred in or out, making it difficult to consolidate investment accounts without losing the principal investment or market gains from fractional shares. This can also force an investor to hold a position they no longer desire, or sell at an undesirable price to consolidate funds.

Liquidity

If the selling stock doesn’t have much demand in the market, selling fractional shares might take longer than hoped or come at a less advantageous price due to a wider spread. It may also be possible to come across a stock with full shares that are liquid but fractional shares that are not, providing difficulty in executing trades let alone at close to market price.

Commissions

Brokerages that charge trading commissions may charge a flat fee per trade, regardless of share price or quantity of shares traded. This can be disadvantageous for someone who can only afford to buy fractional shares, as they’re being charged the same fee as someone who can buy whole or even multiple shares. Over time, these trading fees can add up and siphon limited capital that could otherwise be used to buy additional fractional shares.

Higher transaction fees

Worse yet, some brokerages may even charge higher transaction fees for processing fractional shares, further increasing investor overhead despite investing smaller amounts.

What Happens to Fractional Shares When You Sell?

As with most brokerages that allow fractional shares, fractional shares can either be sold individually or with other shares of the same asset. Capital gains or losses are then calculated based on the buy and sell prices proportionate to the fractional share.

The Takeaway

Fractional shares are an innovative market concept recently made available to investors. They allow investors of all experience and income levels access to the broader stock market—making it worth buying fractional shares for many investors.

Fractional shares have many other benefits as well—including the potential to maximize both DRIP and dollar-cost averaging. Still, as always, it makes sense to pay attention to downsides as well, such as fees disproportionate to the investment, and order limitations.
