Well, this isn't surprising: following a somewhat underwhelming presentation from Microsoft after unveiling the Xbox One (where are the games?), Sony's stock jumped up.
Here's a comparison, with Sony's graph up top. Mind that the conference started at 1pm eastern.
...err. Just a few days ago, Business Insider reported that Microsoft's stock was at a five year high.
Edit: while this stock jump is mostly being pointed out because the timing is funny (the wording is "following" the reveal, not "because of" the reveal), the actual reason that Sony's stock jumped up is because of possible changes to its entertainment division.
