DUHP utilizes the issuer's expertise in combining research, portfolio design, portfolio management, and trading to generate long-term returns. From the broad US large-cap stock universe, the fund selects companies that are considered to have high profitability. A company is considered to have high profitability based on cash flows, earnings, or profits from operations in relation to its book value or assets. Stocks selected for the portfolio are weighted based on their market capitalization, relative price, and/or profitability characteristics. Buy and sell decisions can be based on short-term criteria such as stock momentum, market liquidity, and transaction costs. The fund may use derivatives to leverage exposure or manage cash. Lending of portfolio securities is permitted to generate additional income.
