Square Enix saw its Tokyo stock rating upgraded by Cosmo Securities, to "neutral plus" from the "neutral" rating it has maintained since November 26.
The shares rose 1.9 per cent, to close at JPY 3210 (USD 30.7) on the Tokyo Stock Exchange and much of the improvement is being put down to the performance of the company's Dragon Quest IX DS title, which sold 5 million units.
