About us

Gagnon Securities is a privately held Registered Investment Advisor and Broker-Dealer based in New York.

Since our founding in 2000, we focus on equity investing and manage money for clients in discretionary accounts on both a long only and a hedged basis. We believe that our approach to investing is different, leading us to opportunities our industry peers might not uncover. Diverse in business experience and perspective, we take a research-intensive, generalist approach to evaluating investments for individuals and institutions that produces long-term success.
