In his annual letter to investors, Pershing Square (NYSE:SQ) hedge fund head Bill Ackman said Tuesday that his firm has permanently stopped engaging in activist short-selling and its quieter constructive endeavors don’t raise as much of a fuss as the fight against Herbalife, Business Insider writes.

Known for its “crusade” several years ago against dietary supplement maker Herbalife, Ackman said Pershing Square Capital Management refuses to make such bets in the future.

“Despite our limited involvement in this investment strategy, it has generated a tremendous amount of media attention for Pershing Square. In addition to a huge number of publications 2 our short activist investments have inspired a book and a movie. Fortunately for all of us and, importantly, for our reputation as a benevolent and constructive foundation, we have permanently withdrawn from this work.”

Eckman made this statement to bring clarity to the situation, as some of the investors have repeatedly asked over the past year whether Pershing’s approach has changed as the firm has become a “more relaxed” investor after 5 years since it last participated in the proxy contest.
