Other commodities traded broadly lower for a second straight session, with rice futures retreating from a record and crude oil, copper and silver also falling.

The dollar gained against the euro for a second day after a report showed a surprise drop in the number of Americans seeking jobless claims. Claims for unemployment benefits fell by 33,000 last week to 342,000, the Labor Department said. That contrasted with expectations from economists, who had predicted claims would rise by 3,000.

The euro bought $1.5684 Thursday, down from the $1.5896 it bought late Wednesday. On Tuesday, the dollar fell to a record low $1.6018 against the 15-nation currency.
