What is "motherrock"

MotherRock was an energy sector hedge fund, one of the biggest traders of natural gas derivatives in New York, with assets of around $430 million at one point. It closed in August 2006 due to the high volatility in natural gas valuations in the commodities market. While the high volatility took its toll on MotherRock, its leveraged positions exacerbated the situation and eventually led to a loss of around $230 million in June and July 2006.

The fund was started by J. Robert Collins, with Conrad Goerl and ex-NYMEX vice president John D'Agostino in early 2005.
