  6. While variance captures the dispersion of returns around the mean of an asset in general, volatility is a measure of that variance bounded by a specific period of time.

The statistical concept of a standard deviation allows you to see how much something differs from an average value. When a stock is described as ‘volatile’, it means its price can change dramatically over a short period, either up or down. High volatility often characterizes markets with rapid and significant price fluctuations, whereas low volatility indicates steadier and less dramatic changes in stock prices. On the other hand, “implied volatility” is the market’s perception of how much a stock—or the market itself—will move, and is reflected in the price of its options. Think of implied volatility as the options market’s best guess at future volatility.

The Bottom Line on Market Volatility

If majority of the portfolio is held in equity or stocks and the investor is not patient enough to buy and hold then volatility will have an impact on the strategy. “Particularly in stocks that have been strong over the past few years, periods of volatility actually give us a chance to purchase these stocks at discounted prices,” Garcia says. As an investor, you should plan on seeing volatility of about 15% from average returns during a given year. Standard deviations are important because not only do they tell you how much a value may change, but they also provide a framework for the odds it will happen.

More specifically, you can calculate volatility by looking at how much an asset’s price varies from its average price. Standard deviation is the statistical measure commonly used to represent volatility. Most of the time, the stock market is fairly calm, interspersed with briefer periods of above-average market volatility. Stock prices aren’t generally bouncing around constantly—there are long periods of not much excitement, followed by short periods with big moves up or down. These moments skew average volatility higher than it actually would be most days. For example, let’s say our theoretical company Tiger, Inc. is trading at $100 per share and it has an implied volatility of 35%.

The VIX is often called the fear gauge because fear drives market volatility higher. Sometimes stocks may have low historical volatility and high implied volatility. For one reason or another, traders in the options market expect it to make a big move in the future.

Market volatility is defined as a statistical measure of a stock’s (or other asset’s) deviations from a set benchmark or its own average performance. Loosely translated, that means how likely there is to be a sudden swing or big change in the price of a stock or other financial asset. Some financial instruments are fundamentally tied to volatility, such as stock options. The more volatile the stock, the more the option is valued, since the owner of the option has the option and not the obligation to purchase stocks at a given price. Options are not for the casual investor since options have leverage which will amplify positive and negative returns.

Wrapping Up Our Guide on How to Find Volatile Stocks

Volatility is a key variable in options pricing models, estimating the extent to which the return of the underlying asset will fluctuate between now and the option’s expiration. Volatility, as expressed as a percentage coefficient within option-pricing formulas, arises from daily trading activities. How volatility is measured will affect the value of the coefficient used. When there is a rise in historical volatility, a security’s price will also move more than normal.

When comparing securities, understand the underlying prices as dollar maximum drawdowns may not be a fair comparable base. Because most traders are most interested in losses, downside deviation is often used that only looks at the bottom half of the standard deviation. Because the variance is the product of squares, it is no longer in the original unit of measure.

By the end of the year, your investment would have been up about 65% from its low and 14% from the beginning of the year. Historically, the normal levels of VIX are in the low 20s, meaning the S&P 500 will differ from its average growth rate by no more than 20% most of the time. While heightened volatility can be a sign of trouble, it’s all but inevitable in long-term investing—and it may actually be one of the keys to investing success.

Volatility often refers to the amount of uncertainty or risk related to the size of changes in a security’s value. A higher volatility means that a security’s value can potentially be spread out over a larger range of values. This means that the price of the security can change dramatically over a short time period in either direction. A lower volatility means that a security’s value does not fluctuate dramatically, and tends to be more steady.
