Hedge funds cut bets on a commodity rally to a fouryear low on signs of surplus supply in everything from coffee to zinc before Goldman Sachs said prices had fallen too far and investors should buy. Speculators reduced net-long positions across 18 US futures and options in the week ended March 5 by 9.2% to 405,885 contracts, the lowest since March 2009, US Commodity Futures Trading Commission data show. They are the most bearish on copper in four years, and are also betting on declines for coffee, hogs, sugar, soyabean oil, wheat and natural gas.
