Darlene owns 500 shares of Sandmayor, Inc., common stock that she purchased several years ago for $20,000. During the current year, the Sandmayor stock declines in value. Darlene decides to sell the stock to realize the tax loss. On December 17, she sells the 500 shares for $12,000. Her investment adviser tells her she thinks the Sandmayor stock probably will begin to increase in value next year. On this advice, Darlene purchases 600 shares of Sandmayor common stock on January 10 of the next year for $15,000. The adviser turns out to be right --- Darlene sells the 600 shares in May for $22,000. What are the effects of the sales on Darlene's taxable income in each year? Explain.
