Nikkei falls in choppy trade as investors lock in profits after 4-day gain

TOKYO, July 31 (Reuters) - Japan's Nikkei share average fell on Thursday in choppy trade, breaking a four-day winning streak when profit-taking erased all the gains posted in bouyant morning trade that was supported by solid U.S. growth figures. Nintendo Co dived 6.5 percent after the video game maker posted a worse-than-expected operating loss in the April-June quarter. The Nikkei ended 0.2 percent lower at 15,620.77 after rising to as high as 15,759.66, the highest since Jan. 23.
