Imagine that you are holding 5,000 shares of stock, currently selling at $40
per share. You are ready to sell the shares but would prefer to put off the
sale until next year due to tax reasons. If you continue to hold the shares
until January, however, you face the risk that the stock will drop in value
before year-end. You decide to use a collar to limit downside risk without
laying out a good deal of additional funds. January call options with a strike
price of $45 are selling at $2, and January puts with a strike price of $35
are selling at $3. What will be the value of your portfolio in January (net of
the proceeds from the options) if the stock price ends up at (a) $30? (b) $40?
(c) $50? Compare these proceeds to what you would realize if you simply
continued to hold the shares.
