Beta

How much a share price has tended to move compared with the overall market.

How it’s calculated

A statistical measure of past price movements relative to a market index. 1.0 means the share has moved in line with the market.

How to read it

A beta of 1.5 means the share has historically moved about 50% more than the market in either direction; 0.5 means about half as much. It describes past volatility, not quality.

It is calculated from past prices and can change.
