Which of the following statements is FALSE?
A. When an investor chooses her optimal portfolio, she will do so by finding the tangent line using the risk-free rate that corresponds to her investment horizon.
B. Even though different investors may research different stocks, their information will not impact the market portfolio since there is no way to share this information with other investors.
C. In the real world, borrowers pay higher interest rates than savers receive.
D. If the market portfolio is not efficient, savvy investors who recognize that the market portfolio is not optimal will push prices and expected returns back into balance.
Answer - Even though different investors may research different stocks, their information will not impact the market portfolio since there is no way to share this information with other investors.
Reason - Market portfolio means a portfolio comprised in such a way that it contains shares of all sectors in same proportion as it is in market itself, which makes it move up and down in the same proportion as in market.
Market portfolio provides same return as market, so it can be said that in any given situation of market this portfolio will provide highest possible return at any given risk.
Now, different investors research different stocks and the information is shared in the market.
For example if a company is about to merge with other company and it is probable that the merger will be profitable, the news and research of few investors will reach other investors in market by various means of formal and informal communication like television, social media or spread of word and the demand for share will increase which will inturn increase the price of the share in market.
So it is false that the research of investors doesn't effect market portfolio.
