Global Advisors, a commodity hedge fund manager, said Wednesday it would close two of its three funds due to "poor performance" that prompted investor redemptions, the latest commodity funds to belly up.

London-based Global Advisors, which previously managed about $140 million, said it would close the $60 million Global Advisors Commodity Investment fund and the $5 million Global Commodity Index Plus fund and return money to investors by Sept. 30.
