2021年CFA考试偏向CFA定性考试题，但是CFA考试中还是有定量考试题的，那什么是定量考试题呢？小编给你说是CFA计算题，那你的计算题做的如何呢？

1.Based on historical returns, a portfolio has a Sharpe ratio of 2.0. If the mean return to the portfolio is 20%, and the mean return to a risk-free asset is 4%, the standard deviation of return on the portfolio is closest to:

A．12%.

B．8%.

C．10%.

【答案】B

【解析】

The Sharpe ratio for a portfolio p, based on historical returns, is defined as Where is the mean return to the portfolio is the mean return to a risk-free asset, and sp is the stancard deviation of return on the portfolio In this instance, 2= (20%-4%)/sp Solving for sp: sp = (20%- 4%)/2 = 8%

2.A consumer has a budget of $30 per month to spend on two types of fruit, priced as follows:

·Apples: $2.50 perpound.

·Bananas: $2.00 perpound.

Assuming the quantity of apples is measured on the verticalaxis and bananas on the horizontal axis, the slope of the budget constraint is closest to:

A．1.25.

B．-0.80.

C．-1.25.


【答案】B

【解析】

The budget constraint is given by the formula: 2.5 QA+ 2.0 QB = 30, where QA and QB are quantities of applesand bananas purchased, respectively. With the quantity of apples measured on the vertical axis, the slope is equal to -(PB/PA) =-(2.00/2.50) = - 0.8, where PA and PB are prices of apples and bananas, respectively.
