The fund may invest in emerging market securities. Members of the portfolio management team believe that behavioral biases of investors contribute to market inefficiencies. Their quantitative investment process begins with a proprietary investment-return forecasting model which combines behavioral factors (which seek to capitalize on human behavioral biases (i.e., systematic tendencies) from financial analysts, company management and investors), with intrinsic and valuation factors (which are expected to provide tangible measures of a companys true worth). The portfolio managers integrate this multi-factor approach with a proprietary risk model to form the basis of portfolio construction, with constraints at the individual security, country and industry levels to manage exposures relative to the benchmark. Additionally, all investment recommendations are thoroughly vetted on an individual company level to confirm the investment rationale and suitability before a purchase or sale. In addition to common stocks and other equity securities (such as preferred stocks, convertible securities and warrants), the fund may invest in securities issued in initial public offerings (IPOs), real estate investment trusts (REITs) and may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. The fund typically does not engage in active hedging of currency but retains flexibility to do so depending on market performance. Although the fund did not invest significantly in derivative instruments as of the most recent fiscal year end, it may do so at any time. Show less
