Stock win?

If you were wondering why would Esol Co Ltd put out a press release for this… that’s because companies that had some involvement in Nintendo hardware use this as a trick to try increasing their stock prices. Unfortunately for Esol, the stock was down by 0.14% when the Tokyo stock exchange closed.
