If you own shares in NetScout Systems, Inc. (NASDAQ:NTCT) then it's worth thinking about how it contributes to the volatility of your portfolio, overall. In finance, Beta is a measure of volatility. Modern finance theory considers volatility to be a measure of risk, and there are two main types of price volatility. First, we have company specific volatility, which is the price gyrations of an individual stock. Holding at least 8 stocks can reduce this kind of risk across a portfolio. The second type is the broader market volatility, which you cannot diversify away, since it arises from macroeconomic factors which directly affects all the stocks on the market.
Some stocks are more sensitive to general market forces than others. Beta is a widely used metric to measure a stock's exposure to market risk (volatility). Before we go on, it's worth noting that Warren Buffett pointed out in his 2014 letter to shareholders that 'volatility is far from synonymous with risk.' Having said that, beta can still be rather useful. The first thing to understand about beta is that the beta of the overall market is one. Any stock with a beta of greater than one is considered more volatile than the market, while those with a beta below one are either less volatile or poorly correlated with the market.
What we can learn from NTCT's beta value
Zooming in on NetScout Systems, we see it has a five year beta of 1.36. This is above 1, so historically its share price has been influenced by the broader volatility of the stock market.

Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall.
