According to Bloomberg's David Ingles in Hong Kong, this is the best one-day move for the stock since 1983.

Pokémon Go is a new app from Niantic Inc., which Nintendo has invested in, that uses your phone's GPS to create an augmented-reality world you traverse to catch Pokémon.

This has led to weird things happening to people in the real world trying to catch characters in a fake one.

Also possibly illegal things.
