Tokyo Stocks fell Tuesday morning as a lackluster performance of US and European shares prompted investors to lock in gains following the previous day’s surge. The 225-issue Nikkei Stock Average shed 50.16 points, or 0.35%, from Monday to 14,425.14. The broader Topix index of all First Section issues on the Tokyo Stock Exchange was up 0.59 point, or 0.05%, to 1,163.63, according to Japan’s (Kyodo) News Agency. Tokyo shares got off to a weak start after US and European shares fell overnight following the release of disappointing Chinese economic data.
