Tokyo stocks extended their losing streak to the fourth straight trading day Wednesday, with the Nikkei Stock Average falling 122.19 points, or 1.44%, to end the day at 8,365.90. It was the benchmark index\'s lowest close since June 4, when it fell to a 2012 low of 8,295. The Nikkei average has shed 429 points, or 4.9%, over four days, according to (Nikkei) website. Overseas stocks closed lower overnight in response to concerns about Spain\'s banks and disappointing earnings at US firms. After Apple Inc. announced weaker-than-expected earnings for the quarter through June overnight, related high-tech issues in Japan and other Asian countries were aggressively sold off. The euro\'s fall against the yen also prompted investors to sell stocks of companies that generate much of their sales in Europe. (QNA)
