Tokyo, Sept. 7 (BridgeNews) - Japanese shares ended the morning session broadly lower as steep overnight falls on Wall Street overcame the impact of the nation's April-June GDP data, which was slightly better than expected. Downward momentum was limited, however, as firmer Asia Globex Nasdaq futures suggested a better performance in the U.S. later in the day, traders said. The Nikkei 225 Stock Average fell 222.74 points, or 2.1%, to 10,427.59.
