Before You Buy Mistras Group, Inc. (NYSE:MG), Consider Its Volatility

If you're interested in Mistras Group, Inc. (NYSE:MG), then you might want to consider its beta (a measure of share price volatility) in order to understand how the stock could impact your portfolio. Modern finance theory considers volatility to be a measure of risk, and there are two main types of price volatility. The first category is company specific volatility. This can be dealt with by limiting your exposure to any particular stock. The other type, which cannot be diversified away, is the volatility of the entire market. Every stock in the market is exposed to this volatility, which is linked to the fact that stocks prices are correlated in an efficient market.

Some stocks mimic the volatility of the market quite closely, while others demonstrate muted, exagerrated or uncorrelated price movements. Some investors use beta as a measure of how much a certain stock is impacted by market risk (volatility). While we should keep in mind that Warren Buffett has cautioned that 'Volatility is far from synonymous with risk', beta is still a useful factor to consider. To make good use of it you must first know that the beta of the overall market is one. A stock with a beta greater than one is more sensitive to broader market movements than a stock with a beta of less than one.
