Investment Strategy

The firm's 'Concentrated Value' strategy focuses on a high-conviction, opportunistic selection of approximately 20 large- and mid-cap U.S. stocks believed to be fundamentally strong but temporarily out of favor. For fixed income, M.D. Sass manages portfolios dominated by high-credit-quality U.S. government and agency securities (including MBS and CMOs), using rigorous analysis to control prepayment, extension, and credit risk. The firm emphasizes intellectual honesty, long-term investment horizons, and thorough fundamental and quantitative analysis across all strategies. M.D. Sass also offers a Portable Alpha Fund blending systematic equity index exposure with excess returns sought from fixed income positions, always prioritizing risk control.
