Consider three investors who need to partially liquidate investments to raise cash. In this case all investments have been held for 3 or more years. Investor A waited for a $1,500 qualified dividend distribution from her mutual fund, and investor B received $1,500 in interest income from a CD. However, because Investor C could not wait for a distribution, he decided to sell $1,500 of appreciated stock shares. Assuming no commissions, sales charges, or state income tax, and a 25-percent federal marginal tax bracket, which investment will provide the greatest after tax amount? Would your answer change if all investors were in the 15 percent tax bracket?
