Well, If you hold your expectations too high you are certain to fall. And stock value doubling doesn't near mean Nintendo really is more valuable than Sony as a whole (since Sony gaming part at some points were more valuable than the whole group).
If you think like this then you would have to say Pokemon Go values just as much as Nintendo as a whole (with all the buildings, HW developed, IP owned, etc).
