Last year you sold short 400 shares of stock selling at ​$90.00 per share. Six months later the stock had fallen to ​$45.00 per
a_sh-v [17]

Answer:

The selling of the stocks gave a profit of $16,675.

Step-by-step explanation:

The initial capital was 400 shares, that were valuated at $90.00. This is $36,000.

Six months after, the price drop to $45.00 per share. The stocks that you sold would be valuated a total of $18,000.

That is a relative profit of $18,000.

Then, we have to substract the dividends that you didn't get and the cost of transaction.

The dividends are two payments of $1.50 per share each. The total amount is 400*1.50*2=$ 1,200.

The cost of transaction is $125.

Then, the net profit from selling is:

P = $18,000 - $1,200 -$125= $16,675
