A short-selling contract specifies that an investor needs to have 35 percent initial equity and will be charged a 5.65 percent annual interest rate. The brokerage commission on buying and selling will be charged at 0.13 percent. The contract was for three months and during this contract period, you short-sold 300 shares of investment X at $ 1375 per share in January 2020 and bought 700 shares of investment Yon the same day. In March, a stop-loss order was executed for investment Y when it depreciated by 9 percent, and on the same day you bought investment X after it depreciated by 13%. During this holding period of three months, Investment X paid a dividend twice, each time $ 1.35 per share, and investment Y paid a dividend three times, each time $ 1.79 per share. 

Furthermore, during this holding period the benchmark market index opened in January at 11,539 and closed in March after an appreciation of 14%.
