Just moments ago, Nintendo executive Shigeru Miyamoto made the surprise announcement that Mario is coming to iPhone. This holiday season, Nintendo will release an auto-running Mario game for iOS called Super Mario Run. This is the kind of Nintendo mobile news that investors have been waiting to hear, and that's obvious from the resulting stock hike Nintendo saw. Within minutes of the announcement, Nintendo's stock jumped nearly 30%. That number has tapered off since then, but Nintendo is still up by around 24% on the day, as of 2:00 PM Eastern.
