Suppose that you sell short 300 shares of CYSCO (CY), currently selling for $90 per share, and give your broker $20,000 to establish your margin account.

1. If you earn no interest on the funds in your margin account, what will be your rate of

   return after one year if CY stock is selling at $98? Assume that CY pays no dividends.

2. If the minimum margin is 30 percent, how high can CYs price rise before you get a margin

   call?

3. Redo part (a) and (b), now assuming that CYs dividend (paid at year-end) is $3 per share.
