Shaun bought 300 shares of Dental Equipment, Inc. several years ago for $10,000. Currently the stock is worth $8,000. Shauns marginal tax rate this year is 24 percent, and he has no other capital gains or losses. Shaun expects to have a marginal rate of 32 percent next year, but also expects to have a long-term capital gain of $10,000. To minimize taxes, should Shaun sell the stock on December 31 of this year or January 1 of next year (ignore the time value of money)?
