PS4 gives Sony stock a boost

The PlayStaton 4 reveal has renewed investor confidence in Sony.

Stocks had fallen 1.23 percent today in what some blogs called a "nose dive" before the presentation at 6:00 PM eastern, but after hours trading lifted prices up by 2.42 percent.

This 35 cent gain brought Sony’s value up to $14.82 per share – a significant rise from its low of $9.57 in December.

The enthusiasm for next generation consoles is apparently contagious, and it wasn’t just Sony that climbed the ticker.

Activision stocks, already climbing after the announcement of Destiny, rose another 2.74 per cent after the PS4 presentation.
