Answer:
Beta of 1.0 is the beta of the market, while a beta of 0.0 is the measure for a risk-free security.
Step-by-step explanation:
Beta is the measure of the volatility of returns. It measures the systematic or market risk associated to a stock for any changes that affect the market as a whole. The market beta is always considered to be 1.0 and any stock having a beta higher than the market is more riskier than the market and any stock having a beta less than that of market's is less riskier than the market.
A risk free asset or rate is the rate that remains constant and has no volatility in returns. A risk free rate is usually assigned to short term government securities like T bills. As the risk free rate remains constant and no does not change with changes in market returns, beta of the risk free asset or security is always 0.0
