DFAS, previously a mutual fund, was converted into an ETF with the aims of lowering expenses for its shareholders and delivering long-term capital appreciation. The fund invests in US small-cap companies, which are categorized as the bottom 10% of the total market. DFAS does not have any sector biases, and will invest across a broad range of sectors, assuming these securities meet the funds criteria. Although the fund is generally market-cap-weighted, its active strategy means that the advisor may increase or decrease (or exclude) a companys exposure after considering factors like free float, momentum, trading strategies, liquidity, relative price, profitability, investment characteristics, and other factors that the funds advisor determines to be appropriate.
