Final answer:
Beta measures the volatility of a security relative to the market. A beta of 1.0 indicates a security whose price moves with the market, while a 0.0 beta implies no correlation and represents the measure for risk-free assets like treasury bills.
Step-by-step explanation:
A beta of 1.0 is the beta of the market portfolio, while a beta of 0.0 is the measure for a risk-free asset.
Beta is a indicator of volatility, or systematic risk, of a security in comparison to the market.
A security with a beta greater than 1.0 is expected to be more volatile than the market, whereas a security with a beta of less than 1.0 is expected to be less volatile.
On the other hand, a beta of 0.0 implies that the security is uncorrelated with the market and is considered to possess no systemic risk, which is typically attributed to risk-free assets like government treasury bills.
