At the end of one year, you buy 100 shares of Charlotte at $45 to close out your position and are charged a commission of $145 and 8 percent interest on the money borrowed. What is your rate of return on the investment? 5. You own 200 shares of Shamrock Enterprises that you bought at $25 a share. The stock is now selling for $45 a share. a.

If the stock eventually declines in price to $30 a share, what would be your rate of return with and without the stop loss order? 6. Two years ago, you bought 300 shares of Kayleigh Milk Co. for $30 a share with a margin of 60 percent. Currently, the Kayleigh stock is selling for $45 a share. Assuming no dividends and ignoring commissions, compute (a) the annualized rate of return on this investment if you had paid cash, and (b) your rate of return with the margin purchase. 7. The stock of the Madison Travel Co. is selling for $28 a share. You put in a limit buy order at $24 for one month. During the month the stock price declines to $20, then jumps to $36. Ignoring commissions, what would have been your rate of return on this investment? What would be your rate of return if you had put in a market order? What if your limit order was at $18?
