This screen is based on the momentum-focused approach of Richard Driehaus, a mutual fund guru who was named to Barron’s “All-Century” team of the 25 most influential and powerful mutual fund managers in 2000. It focuses on companies with momentum in earnings and prices, particularly small- to mid-cap companies with strong, sustained earnings growth that have had “significant” earnings surprises. At the core of his strategy are earnings surprises. Companies with positive earnings surprises are buys and negatives are sells. It also values surprises in which the range or standard deviation of estimates is tighter, which has a more significant impact on subsequent returns. This strategy looks for companies with positive price momentum over the last four weeks and also considers how stocks do on a relative basis versus the S&P 500. Driehaus prefer small to mid cap stocks. The investor may also wish to monitor liquidity in terms of trading volume. more »
