The fund sells A-category shares with a front-end load of 6% and B-category stocks with 12b-1, fees of 0.5% annually, and back-end load fees that start at 5% and fall by 1% for each full year the investor holds the portfolio (until the fifth year). Assume the portfolio rate of return net of operating expenses is 10% annually. Which stock category is a better choice for you for a fund life of 4 years? What if you plan to sell after 15 years?
