An investor sells 100 shares short at $43. The sale requires a margin deposit equal to 60 percent of the proceeds of the sale. If the investor closes the position at $49, what was the percentage earned or lost on the investment? If the position had been closed when the price of the stock was $27, what would have been the percent earned or lost on the position? (ignore any dividends, interest or commissions that would normally apply in a short sale)
