Our Philosophy

Granahan Investment Management (GIM) believes that earnings drive stock prices, and that small dynamic companies with exceptional growth prospects provide the greatest potential for superior long-term performance. Over time, active management of the smaller cap sector has outperformed a passive approach. GIM believes this is because the smaller cap area of the market is not as well followed by the investment banking community; therefore, opportunities to “discover” companies when they are not fully valued are more abundant. A bottom-up, fundamental approach to research is the only method that can both uncover and appropriately value stocks in the small cap arena.

At GIM, every research candidate is placed into one of three investment categories: Core Growth, Pioneer and Special Situation. In addition to strong earnings growth, the common thread among these categories is a leadership position in the specific company’s marketplace. We consciously diversify our clients’ portfolios across the three investment categories to reflect our belief that growth stocks outperform over time, and to ensure that we capitalize on both dynamic emerging growth stocks and those that provide stability in the portfolio as undervalued stocks with bright earnings growth prospects.
