Volatility in the stock market: what it means and how to manage it

Here鈥檚 how you can make market volatility work for you.

Article published: August 22, 2023

The stock market is in constant flux with different indexes experiencing gains and losses each trading day. More recently, even during relatively calm periods, the S&P 500 will still go up and down by less than 1%.1 While these changes aren鈥檛 always dramatic, there are times when the stock market will take you on a roller coaster of highs and lows 鈥 a phenomenon known as 鈥渧olatility.鈥

Of course, the pandemic was a prime example of high volatility, but more recently, we saw a week of price swings following the closures of Silicon Valley Bank and Signature Bank.2 Volatile market events can be rattling for any investor 鈥 especially when there鈥檚 a bear market. But they are also inevitable.

So, how can you develop an investment strategy that can not only weather these storms but potentially take advantage of rapid stock price changes?


Before we dive into strategy, it鈥檚 important to understand what stock market volatility really means. 鈥淒ramatic gains and losses鈥 is a decent descriptor, but volatility is also a measure of the frequency and scale of stock price swings. For instance, high volatility is when stock values continue to fluctuate by greater than 1% per day for a prolonged time.3 On the other hand, a period of low volatility may be characterized by infrequent and insubstantial changes.

Generally, greater volatility carries more risk to the investor; but 鈥 unless you want to divest all your wealth into CDs, cash or money market funds 鈥 managing it isn鈥檛 about avoidance. Instead, it鈥檚 about choosing an investment strategy with the right level of volatility that can help:

Historical volatility

Historical volatility uses the standard deviation in price swings over time to determine the likelihood of a stock drifting away from the average price. Calculations are usually based on changes between each closing price, but they can also include fluctuations that occur during the trading day. Generally, they gauge volatility on time scales ranging from a week to a year

When historical volatility is high, the stock price is expected to fluctuate more significantly and with greater frequency. In contrast, when this metric is low, it implies the company has mitigated uncertainty and is returning to a stable period.4

How is market volatility measured?

Stock market volatility is often measured using the standard deviation of stock market index price changes over time. Portfolios with a higher standard deviation tend to be more volatile and may have greater movement up or down.

What drives high volatility?

As a reflection of the way investors currently feel about the market, volatility represents uncertainty, not necessarily pessimism. While you can鈥檛 be inside the head of each investor, you still need to understand how economic and political changes and events might impact sentiment. For instance, during times of rising interest rates or political instability, you may see increased volatility in the financial market.

Sometimes there can be excessive volatility in the same day. If stock in a company jumps say 20% in a single day, you might not be worried. However, when markets become especially turbulent, the exchanges might step in to put a trading curb in place. This stops market participants from trading for a given period of time 鈥 up to a day in some cases 鈥 allowing things to cool off and stabilize. But what might cause volatility to get that high?

Individual company factors

Starting off small, business performance can be a key driver of volatility in stocks. When a company outperforms expectations, investors often want to buy in, which may increase the stock price. On the other hand, if a business experiences a significant problem 鈥 either with its products, services or people 鈥 it can worry shareholders, causing them to sell off en masse. In the case of large enterprises, these fluctuations can have far-reaching effects on much broader markets.

Industry-specific factors

On a broader scale, events within a specific market, like supply chain disruption, can have huge effects on volatility. For example, when the pandemic led to a global chip shortage, auto manufacturers were unable to meet demands and the industry experienced a period of high volatility that actually bumped chipmakers鈥 stock prices up eventually.5 In general, incidents like supply disruptions, natural disasters, bankruptcies and government regulations can cause market volatility for impacted industries.

Economic factors

Zooming out further, the economy plays a big role in market volatility. When the economy is doing particularly well, investors might even see a bull market where prices continue to rise. Conversely, factors like GDP, consumer spending or inflation can cause a sharp decline in the market. In either case, the economy experiences volatility with both positive and negative effects.

Political factors

Finally, governments making decisions around policies, trade agreements and regulations can have some of the largest impacts on the financial market. But it鈥檚 not just legislation that can cause volatility. Investor behavior can change from anything, including speeches and elections 鈥 as we saw in 2020. On the extreme end, we can look at the Russian invasion of Ukraine, which caused the price of commodities like grain to rise dramatically. The war has also caused a boost in defense stocks with more countries already increasing or expected to grow their military spending for the foreseeable future 鈥 another example of politically driven volatility.6

Volatility vs. Risk

While volatility and risk are closely related, they aren鈥檛 interchangeable terms.

Whereas volatility measures the frequency and magnitude of price swings, risk represents a wide variety of factors that can be measured in many ways. Of course, all investments have risk 鈥 some more than others. High volatility often coincides with increased risk, but this isn鈥檛 always a drawback. And it may be the case that stock markets aren鈥檛 experiencing significant price volatility, but that doesn鈥檛 mean there鈥檚 no risk of unforeseen swings when economic or political news arrives.

High volatility doesn鈥檛 always equal high risk. Similarly, a volatile period doesn鈥檛 necessarily equate to downside risk. Downside risk refers to the potential for negative or unfavorable outcomes in a market, but upside risk measures the uncertain possibility of potential gains.

Is volatility a bad thing?

Just as risk isn鈥檛 necessarily a bad thing, neither is volatility. In fact, it can open the door to plenty of new investing opportunities. For example, a bear market can offer you the chance to purchase additional stocks at a lower price for companies you believe will outperform in the long run. During a bull market, you can do the opposite, selling off high-performing stocks to reinvest in other areas. It all depends on the type of investor you are and your tolerance for risk.

How to manage volatility in your portfolio

Ultimately, how you react to and manage volatility in your portfolio will depend on a number of personal factors that guide your investment strategy. But trying to make adjustments to your portfolio to outguess or time market volatility isn鈥檛 a good investment tactic.

Even experts like mutual fund managers and other financial professionals can鈥檛 successfully do this on a consistent basis. Remember that downturns will come and go in investing, and past performance won鈥檛 guarantee future results, but both stocks and bonds have historically performed well over the long run.

Next time volatility in the stock market has you questioning your investment strategy, try one of these tips:

Build a rainy day fund

The first step to quell fears around volatility is to ensure you and your family are protected with an emergency fund. If an incident occurs and you suddenly need access to cash, you don鈥檛 want to have to sell all your invested assets to sustain your income. Developing a safety net of cash you can dip into for living expenses can give you peace of mind while keeping your portfolio on track. This is especially true for those nearing retirement, who should have a much bigger pool of assets that aren鈥檛 at risk of market volatility.

Rebalance your portfolio

Whether the market experiences a sudden surge or staggering fall, you鈥檒l want to review your current asset allocation as it might have drifted from your initial weighting. Take the time to consider rebalancing your portfolio by selling off more of your high-performing asset classes and diverting those funds to ones that may have shrunk recently.

View volatility as opportunity

If you take one thing away from this article, it should be that volatility is not your enemy. Instead of avoiding it, try thinking about fluctuations as an opportunity. If the market is spiraling downward, it might be a good time to assess your portfolio and reallocate funds toward underweighted asset classes. On the other hand, when the market is on the rise, selling off high-performing assets and reinvesting those returns may help you rebalance your portfolio.

An index is a portfolio of specific securities (such as the S&P 500, Dow Jones Industrial Average and Nasdaq composite), the performance of which is often used as a benchmark in judging the relative performance of certain asset classes. Indexes are unmanaged portfolios and investors cannot invest directly in an index. Past performance does not guarantee future results.

Investing strategies, such as asset allocation, diversification or rebalancing, do not ensure or guarantee better performance and cannot eliminate the risk of investment losses. All investments have inherent risks, including loss of principal. There are no guarantees that a portfolio employing these or any other strategy will outperform a portfolio that does not engage in such strategies. Past performance does not guarantee future results.
