题目
For an investor to move further up the Capital Market Line than the market portfolio, the investor must:
选项
A.reduce the portfolio's risk below that of the market.
B.continue to invest only in common stocks.
C.borrow and invest in the market portfolio.
D.diversify the portfolio even more.
答案
C
解析
Portfolios that lie to the right of the market portfolio on the capital market line ("up" the capital market line) are created by borrowing funds to own more than 100% of the market portfolio (M). The statement, "diversify the portfolio even more" is incorrect because the market portfolio is fully diversified.通过借入资金以拥有超过100％的市场投资组合（M）的方式，在资本市场组合（位于资本市场线上方）上位于市场投资组合右侧的投资组合。 因为市场投资组合已经完全多样化，所以“使投资组合更加多样化”的说法是错误的。
