Accounting the annualized standard deviation of daily change in price leads to evaluation of volatility in share market. In simple terms, if the price of astock moves up and down rapidly over short time periods, it has high volatility in share market. If the price almost never changes, it has low volatility.
Many Investors feel that when volatility in share market is high, it is time to buy but when it is low you should not step into market. On the contrary, a number of studies have also shown that when volatility in share market rises, there is a greater chance that the stock market is experiencing losses. Basically, when the stock market is climbing, volatility tends to decline. On the other hand when the stock market falls, volatility in share market tends to rise. So if you go by above said theory you should be more conscious of the volatility in the market as you make buy and sell decisions.
Volatility in share market is calculated by a simple mathematical term called beta that shows how volatile the security is compared to the market. Beta measures U.S listed stocks and funds. A beta greater than 1 means the stock or fund you are looking at is more volatile than the broader market. Beta measures this volatility risk for securities trading in the market, where information about securities is integrated into prices.
