Beta helps investors understand the systematic risk of a stock and its potential reaction to market changes. If the beta score exceeds 1, it implies a higher level of volatility, whereas a beta ...
It refers to an asset's non-diversifiable risk, systematic risk, or market risk. Beta is not a measure of idiosyncratic risk. Beta is the hedge ratio of an investment with respect to the stock market. For example, to hedge out the market-risk of a stock with a market beta of 2.0, an investor would short $2,000 in the stock market for every ...
For example, if the market is making a big move 20% higher, a stock with a beta of 1.5 will tend to trade up 30%. In this way, an investor can maximize gains in a bullish market by picking up ...

Betas exceeding one signify more than average "riskiness" in the sense of the asset's contribution to overall portfolio risk; betas below one indicate a lower than average risk contribution.

The SCL is plotted on a graph where the Y-axis is the excess return on a security over the risk-free return and the X-axis is the excess return of the market in general.
