Why Volatility is Important for Investors
But for long-term goals, volatility is part of the ride to significant growth. The volatility of stock prices is thought to be mean-reverting, meaning that periods of high volatility often moderate and periods of low volatility pick up, fluctuating around some long-term mean. This is a measure of risk and shows how values are spread out around the average price.
Whether volatility is a good or bad thing depends on what kind of trader you are and what your risk appetite is. For long-term investors, volatility can spell trouble, but for day traders and options traders, volatility often equals trading opportunities. If prices are randomly sampled from a normal distribution, then about 68% of all data values will fall within one standard deviation. Ninety-five percent of data values will fall within two standard deviations (2 x 2.87 in our example), and 99.7% of all values will fall within three standard deviations (3 x 2.87). While volatility refers to the frequency and magnitude of price fluctuations in an asset, risk pertains to the probability of not achieving expected returns or losing one’s investment. Remember, because volatility is only one indicator of the risk affecting a security, a stable past performance of a fund is not necessarily a guarantee of future stability.

The recent history of market crashes often points to unexpected triggers that were external to the regular economic and financial indicators. Central banks around the world use interest rates as a tool to either stimulate economic growth or curb inflation.

Volatility is the result of supply and demand forces on any specific stock, ETF, or other type of security. Those forces do not produce equal reactions in the price of all securities. Some securities are more leveraged or have more uncertainty in their businesses than others, causing volatility to differ among them. And there’s always the potential for unpredictable volatility events like the 1987 stock market crash, when the Dow Jones Industrial Average plummeted by 22.6% in a single day.
Since unforeseen market factors can influence the volatility, a fund with a standard deviation close or equal to zero this year may behave differently the following year. A fund with a consistent four-year return of 3%, for example, would have a mean, or average, of 3%. The standard deviation for this fund would then be zero because the fund’s return in any given year does not differ from its four-year mean of 3%. On the other hand, a fund that in each of the last four years returned -5%, 17%, 2%, and 30% would have a mean return of 11%. This fund would also exhibit a high standard deviation because each year, the return of the fund differs from the mean return. This fund is, therefore, riskier because it fluctuates widely between negative and positive returns within a short period.
