true or false the beta for the portfolio after the stocks have been added is the weighted average of the beta before the stocks were added and the beta of the new stocks that are being added (weighted as a percentage of the total funds invested
Aparna S.
The beta of a firm's stock indicates the degree to which changes in stock price track changes in the stock market as a whole and is interpreted as the market risk of the portfolio. A beta of 1.0 indicates that, on average, the stock rises (or falls) the same percentage as does the market. A beta of 2.0 indicates a stock that rises or falls at twice the percentage of the market. The beta of a stock portiolio is the weighted average of the betas of the individual stock securities, weighted by the current market values (market value is share price times number of shares). Consider the following portfolio: 100 shares Speculative Computer at $$\$ 35$$ per share, beta $=2.4$ 200 shares Conservative Industries at $$\$ 88$$ per share, beta $=0.6$ 150 shares Dependable Conglomerate at $$\$ 53$$ per share, beta $=1.2$ a. Find the beta of this portfolio. b. To decrease the risk of the portfolio, you have decided to sell all shares of Speculative Computer and use the money to buy as many shares of Dependable Conglomerate as you can. ${ }^{16}$ Describe the new portfolio, find its beta, and verify that the market risk has indeed decreased.
A portfolio's beta is... Group of answer choices the weighted average of the individual stocks' betas, where the weights are determined by the market capitalizations of each stock. is close to zero if the portfolio is large. the same as the highest beta of all the stocks in the portfolio. the square root of the weighted average of the squares of the individual stocks' betas.
