TOKYO -- The Tokyo Stock Exchange overhauled its grouping of shares for the first time in six decades on Monday, seeking to attract overseas investors by offering a top tier of 1,839 blue chips that clear tougher hurdles for corporate governance than the old first section.
Tokyo stocks drifted around a flat line for most of the day but managed to close higher after a three-day fall. The Nikkei Stock Average finished up 70.49, or 0.25%, at 27,736.47. In the Prime market, the exchange's top-tier section, 67% of the issues closed higher.
