Beta coefficient

It is a measurement of the relative volatility in stock prices, ie it shows how "mobile" the price of a particular stock is in relation to everything else on the market. Incidentally, the basic codes (e.g., S & P500) have the reference "beta", which equals unity. Accordingly, a stock with a "beta" that is more than 1 is more volatile (see), and when a "beta" is less than 1, it's less volatile.
