Shares of Simplex Investments Advisors Inc soared 10.8 per cent to 144,000 yen on the Tokyo exchange's Mothers section for start-ups.

The broader TOPIX index inched lower by 0.08 per cent or 1.33 points to 1,654.27.
Casio Computer tumbled 19.1 per cent to 1,272 yen after the company cut its operating profit forecast for the current business year by 30 per cent due to sluggish mobile phone sales, missing market expectations.

Shares of KDDI climbed 3 per cent to 870,000 yen after Goldman Sachs lifted a rating on Japan's No. 2 mobile phone operator to ''buy'' from ''neutral,'' saying no ''domino'' price cuts are expected.
