Japanese shares plunged on Wednesday as the majority of stocks were traded ex-dividend. Depressing the Japan's stocks further, global growth concerns escalated on protests in Spain over fresh austerity measures and disappointing comments from the Fed official. Moreover, analysts expect the BoJ Tankan report to indicate that business confidence deteriorated for the fourth quarter in a row in Q3. The report is due on October 1. The Nikkei 225 Index slid 2.03% to close at 8,906.70. All sectors within the index posted losses. The worst-performers were technology and basic materials. Canon, Alps Electric and Konica Minolta Holdings tumbled 4.47%, 4.10% and 1.69%, respectively. Asahi Kasei Corp and Kobe Steel plunged 1.92% and 3.03%. On the downside were also banks, with Bank of Yokohama and Chiba Bank slid 1.05% and 0.54%.
