Regardless of who’s doing the buying — hedge funds, institutional buyers, BUFFET (just kidding) — obviously there’s a bullish outlook for the stock.

I think the feeling is that the Hollywood video purchase last year could turn profitable, both from cost-cutting and as a possible takeover. Considering this stock clearly bottomed out in March and has made such a strong upturn, I’d bet someone knows something that most of us don’t.

Remember, buy on the rumor…
