Anyone researching ams AG (VTX:AMS) might want to consider the historical volatility of the share price. 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 are more sensitive to general market forces than others. Beta can be a useful tool to understand how much a stock is influenced by market risk (volatility). However, Warren Buffett said 'volatility is far from synonymous with risk' in his 2014 letter to investors. So, while useful, beta is not the only metric to consider. To use beta as an investor, you must first understand that the overall market has a beta of 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.
