Answer:(d) A numeric value that measures the fluctuations of a stock to changes in the overall stock market.
Explanation:
Beta is a measure of a stock's sensitivity to market movements. It quantifies the relationship between the price movement of an individual stock and the overall market. A stock with a beta greater than 1 is expected to be more volatile than the market, while a stock with a beta less than 1 is expected to be less volatile.
Beta is used by investors and analysts to assess the risk associated with a particular stock or portfolio. It helps in understanding how much a stock's price is likely to move in relation to the broader market. A high beta indicates a higher level of risk, as the stock tends to fluctuate more in response to market movements. On the other hand, a low beta suggests lower volatility and potentially less risk.
