A snack maker suddenly tumbled the most in more than a year in Hong Kong, with traders speculating someone may have mistakenly sold the stock.

Want Want China Holdings Ltd. lost as much 7.8% just as the pre-market session opened, with some 101,000 shares changing hands at the intraday low of HK$5.65, according to data compiled by Bloomberg. Want Want, a member of the Hang Seng Index, quickly erased the losses within minutes after regular trading started. It added 1.1% at the close to be the best performer on the index, which fell 0.8%.
