问题如下:

Daisy shorts 1800 shares of KIY company's stock on a 30% initial margin and the broker's lending rate is 2.5%. The current price is $65 per share. The broker charges a commission of $0.02 per share on sales but purchases for free. KIY stock pays an annual dividend of $1 per share. One year later, Daisy buys the 1800 shares at a price of $58 per share and close the position.Which of the following is closest to Daisy's rate of return?

选项:

A.

24.98%.

B.

24.81%

C.

32.55%.

解释:

B is correct.

Initial principal = 1800*65*0.3= 35100. The commission on sale( calculating as a part of initial cost)=1800*0.02=36

Remaining principal=1800*65*0.7=81900 ,so the first expense---lending interest=81900*2.5%=2047.5

The second expense---dividend payment=1*1800=1800, and there is no purchase commission.

The return on this investment=1800*65-1800*58-36-2047.5-1800=8716.5

Yield=8716.5/(35100+36)=24.81%

请老师解释一下这题的做法 和演示一下公式

这种题型大原则就是用 【赚或者亏】/初始投资成本;

其次本题是short sales,

那么【卖空-买入-借款利息-红利(红利是属于broker)-佣金】/【本金30%+佣金】
