Helen holds 1,000 shares of Fizbo Incorporated stock that she purchased 11 months ago. The stock has done very well and has appreciated $20/share since Helen bought the stock. When sold, the stock will be taxed at capital gains rates (the long-term rate is 15 percent and the short-term rate is the taxpayer's marginal tax rate). Ignore the time value of money.

Required:

1. If Helen's marginal tax rate is 35 percent, how much would she save by holding the stock an additional month before selling?
2. What might prevent Helen from waiting to sell?
