1. An investor sells 200 shares short at $50. The sale requires a margin deposit equal to 60 percent of the proceeds of the short sale. The company paid a cash dividend of $1.50 per share. If the investor covered the position at $45, what was the percentage earned or lost on the investment? (1 point) 2. Suppose that you opened a margin account (margin requirement = 50%) with your brokerage rm and invested in 100 shares of Mercer Inc. stocks at $80 per share two years ago. While you held the stocks (2 years = 8 quarters), the rm paid out $1.00 dividend per share each quarter. If you sell the stocks at $90 per share today, what is the percentage return for your investment? Assume that the commission rate is 5 percent of the purchase and sale price, and you need to pay 10% annual interest on the borrowed fund every year. (1 point) 3. Worker A annually invests $1,000 in an IRA pension account for ten years (ages 26 through 35) and never makes another contribution. Worker B annually invests $1,200 in an IRA account for thirty years (ages 36 through 65). Which worker will have more in his or her account when he or she retires (at the age of 65) if they both earn 8 percent on their investments? Provide detailed calculation. (1 point)
