Peconic Partners is a registered investment advisor managing proprietary and client capital through long/short equity hedge fund strategies.

Our investment objective remains constant: producing long-term positive results, regardless of market conditions. We navigate with an awareness of short-term economic trends while maintaining a long-term perspective, allowing us to maximize earnings and minimize risk. We believe that our long-term track record, history of capital generation, and past ability to generate alpha are all testaments to the vision, insight, and patience deriving from our experience.

The Peconic Partners investment strategy has 20+ years history, beginning with our predecessor firm, which was managed by Peconic founder William Harnisch from the late 1970s until 1997, when the long-only business was sold to a privately-held financial services firm seeking to expand its asset management business. Mr. Harnisch and his partners continued to retain exclusive ownership of the hedge business, and in December 2004, he and the current Peconic team separated to form Peconic Partners, as a dedicated continuation of the successful and disciplined hedge fund strategy that has been practiced since the late 1970s.


Peconic’s leadership provides the experience and infrastructure to support a team of industry specialists, who work synergistically across sectors for idea generation and are versed in fundamental, quantitative, and technical analyses.
