Nintendo has not had a good few years- the launch of the 3DS was a failure, and while the system recovered, it represented a huge decline over the original DS. The Wii U, on the other hand, was a catastrophic failure, leading to Nintendo suffering huge losses the last few years.
Nintendo’s stock fell from an all time high in 2009 to some really low levels. The stock started recovering last year as, between its mobile offerings, the Pokemon GO mania, and the hype around the upcoming Nintendo Switch, Nintendo started to show signs of recovery. However, now, on the back of the launch of the Switch, and record breaking sales for its games and hardware, Nintendo’s stock is apparently steadily climbing- in fact, it is right now the highest it has been in the last seven years, higher than at the peak of Pokemon GO mania (as spotted by NeoGAF).
This shows that investors have some confidence in what Nintendo is doing- now Nintendo has to come out swinging at E3 this year, and announce some great games. That crazy Rabbids crossover RPG that was leaked yesterday would be good start!
