Tokyo stocks lose ground on firm yen, U.S. economy concerns

TOKYO, May 15 (Xinhua) -- Tokyo stocks retreated Monday morning with a comparatively firm yen against the U.S. dollar after weak U.S. economic data driving exporters lower in particular.

The 225-issue Nikkei Stock Average lost 41.75 points, or 0.21 percent, from Friday to 19,842.15.

The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, fell 3.83 points, or 0.24 percent, to 1,576.88.

Mining, iron and steel, and nonferrous metal-linked stocks comprised those that declined the most by the morning break.
