Dual fund shares allow individuals to satisfy their divergent preferences for the ordinary income and the capital gains components of return. Institutional restrictions on short selling are shown to permit discounts on dual funds to fluctuate within wide bounds. However, these fluctuations are shown to be consistent with informational efficiency. The average discount is shown to have a contemporaneous association with net redemptions of diversified open-end funds. It is shown that the high turnover of dual fund portfolios is not warranted by their portfolio performance and causes redistributions of wealth between income and capital shareholders.
