The Funds investment strategy is based on an assumption that stock prices over time follow earnings and companies that can sustain above average growth in earnings will out-perform the growth indices and, long-term, the market overall. However, markets often overreact to near term events and extrapolate recent experience into the current stock price. In this context, successful growth investing requires in-depth fundamental research in order to differentiate sustainable growth from short-lived events. This fundamental research is then coupled with a valuation assessment to evaluate the upside potential for investing in a company. Using a unique valuation measure in each industry, the Sub-Adviser ranks each stock based on its estimated upside return potential relative to its downside risk. The Sub-Adviser typically purchases companies that rank in the top third based on this measure and sells the stocks when they fall below the median. Show less
