题目
The market portfolio in Capital Market Theory is determined by:
选项
A.a line tangent to the efficient frontier, drawn from any point on the expected return axis.
B.a straight line drawn to any efficient portfolio.
C.a line tangent to the efficient frontier, drawn from the risk-free rate of return.
D.the intersection of the efficient frontier and the investor's highest utility curve.
答案
C
解析
The Capital Market Line is a straight line drawn from the risk-free rate of return (on the Y axis) through the market portfolio. The market portfolio is determined as where that straight line is exactly tangent to the efficient frontier.资本市场线是从无风险收益率（Y轴）到市场投资组合的直线。 市场投资组合被确定为该直线与有效边界正好相切的位置。
