Tokyo stocks extended their losing streak to the sixth straight session Tuesday, with the Nikkei Stock Average closing down 8.24 points, or 0.09%, at 9,538.02. It was the first six-day fall since July 2009. The index traded higher in the morning, but investors began selling exporters aggressively in response to the yen\'s weakening to the lower-81 level against the dollar after the Bank of Japan said that it will not take further monetary-easing measures, according to (Nikkei) website. Concerns about a Chinese economic slowdown triggered by weaker-than-expected import data also prompted selling. The Nikkei average briefly rose by more than 100 points in the morning, as investors expected stocks to rebound on a near-term basis and speculated that the BOJ would implement additional easing measures.
