Sony’s stock closed today at 22.91 points, nearly two points higher than it was eight hours before. That’s good for a 9.25 percent jump in Sony’s market price, an outrageous jump that many companies would kill for. Then again, with such a low market valuation, such jumps aren’t unheard of for companies in Sony’s position.

Microsoft's stock closed down 0.66 percent, seemingly unaffected one way or another by Xbox One.Your first instinct might be that this has to do with Xbox One’s reveal, which was light on games and heavy on entertainment. That might be part of it, but as Bloomberg reports, the stock jump seems to have been driven primarily by a rumor we first reported on last week: Sony may be spinning off its entertainment division.Bloomberg notes that the jump correlated directly with a report from massive Japanese newspaper Nikkei that the company is indeed “leaning toward spinning off its entertainment division,” which is primarily comprised of Sony Pictures Entertainment and Sony Music Entertainment. Such a move was first publically suggested by Daniel S. Loeb, a hedge fund manager who happens to own 6.5 percent of Sony.The article also notes that “Sony executives are holding their regular corporate strategy meeting in Tokyo tomorrow. The company has relied on profit from its entertainment division to offset losses from its flagship consumer electronics business.”What Sony’s actual strategy is remains to be seen, but between this fresh Nikkei rumor and, presumably, Xbox One’s reveal, Sony’s stock is surging.
