exchange rules that proceeds from a short sale must be kept on account with
the broker.
(cash $5600)

short-seller also are required to post margin (cash or collateral) with the
broker to cover losses should the stock price rise during the short sale.
(margin 5600*45%=$2520)

所以investor沒有借現金,因此不用負擔利息
(但利息的確是你的機會成本)

although large or institutional invsetors typically will receive some
income from the proceeds of a short sale being held with the broker.
(一般來說,account中的interest是broker賺走,但這個情況下,interest就是加項了)

※ 引述《sonia888 (sonia)》之銘言:
: 放空(sell short)是借券出售。
: 你借100股,並以@$56出售,共得到$5,600。
: 保證金(margin requirement)是45%,所以你須繳交$5,600×0.45=$2,520的保證金。
: 為了保證將來有足夠的錢可以買回股票來還券,除了繳交的保證金以外,你還須借總售股
: 金額($5,600)扣除保證金($2,520)後的餘額($5,600-$2,520=$3,080),也就是
: $5,600×0.55=$3,080的部分。
: 既然這$3,080的部分是借款,你當然要在回補之後,計算應繳的利息,也就是$5,600×
: 0.55×0.08=$246.40。
: 所以計算投資報酬率時,須把此利息算為成本,作為減項。
: 你之所以把此減項誤作為加項,是因為你誤把放空賣掉的股票收入,視為你的錢,所以誤
: 以為有利息收入。

: : cash is not borrowed and so interest is not charged
: : profit = 5600-4500-250-300 = 550
