Xbox One Announced And Sony's Stock Price Explodes
In the time between Microsoft's announcement and the close of trading in New York Sony's shares posted a remarkable 9% increase.
Clearly the Xbox One launch was a good advert for Sony's PS4, in the battle for the living room.
I'm not sure what it could be, but there's a lot of people who saw today's Microsoft announcement as a reason to grab large numbers of Sony stock.
Someone should be worrying right now.
