practical tips for trading in volatile markets
Calculated by prices in options, a higher VIX reading signals higher stock market volatility, while low readings mark periods of lower volatility. In simple terms — when the VIX rises, the S&P 500 will fall which means it should be a good time to buy stocks. Many investors have experienced abnormal levels of investment performance volatility during various periods of the market cycle.
Most typically, extreme movements do not appear ‘out of nowhere’; they are presaged by larger movements than usual or by known uncertainty in specific future events. Whether such large movements have the same direction, or the opposite, is more difficult to say. And an increase in volatility does not always presage a further increase—the volatility may simply go back down again.
Volatility Defined
Smooth trending markets or rangebound markets can also be interrupted by sharp shocks and unwanted volatility. Unfortunately, there are three main reasons why investment performance data may not be normally distributed. First, investment performance is typically skewed, which means that return distributions are typically asymmetrical.
What is the approximate value of your cash savings and other investments?
It is calculated as the standard deviation multiplied by the square root of the number of time periods, T. In finance, it represents this dispersion of market prices, on an annualized basis. Investors can find periods of high volatility to be distressing, as prices can swing wildly or fall suddenly. Long-term investors are best advised to ignore periods of short-term volatility and stay the course. Meanwhile, emotions like fear and greed—which can become amplified in volatile markets—can undermine your long-term strategy. The R-squared of a fund shows investors if the beta of a mutual fund is measured against an appropriate benchmark.

Risk involves the chances of experiencing a loss, while volatility describes how much and quickly prices move.
