Yesterday, Nintendo's stock closed at its highest level in the last two years, and this sudden surge has been largely attributed to the successful sales of Animal Crossing: New Leaf. It's further suggested that the numerous sales of this game has also increased sales of the 3DS itself.
Bloomberg analysts also believe that this jump is partially due to China lifting its console ban, which can only help Nintendo's hardware sales.
When the stock market closed yesterday, Nintendo's stock had spiked four percent in Tokyo trading, the highest it has been since July 2011.
