Nintendo Shares Skyrocket After Smartphone News

In the wake of Nintendo's two major announcements today, one of which involved the Japanese game giant signing a deal with DeNA to make mobile games, the company's shares are skyrocketing. At press time, stock value is up by more than 30 percent on the Tokyo Stock Exchange.

Investors had long called for Nintendo to move into the smartphone and tablet gaming market, so it's not too surprising to learn that share value is rising fast as a result of the news.

Nintendo's stock value has reached a new high for 2015. But as you can see in the graph below, share value is still well below what it was during the 2007/2008 Nintendo Wii days.

Nintendo is not planning to simply port its games to smartphones and tablets, instead electing to create all-new experiences based on its catalog of popular IP for those devices. The first of these games will be released this fall. Further details about the Nintendo-DeNA deal, however, are being kept under wraps for now.

The other piece of news Nintendo announced today was that it had started work on what president Satoru Iwata called a "dedicated game platform with a brand-new concept." Unfortunately, no further details on the system--codenamed NX--are available. Iwata said additional details about this new platform will be announced in 2016.
