Yes, someone is buying, and I suspect that it is many people, including some who are posting here.
It's not just hpq that people are buying, but nearly everything else, as well. The DOW is at an all time high, and the S&P 500 is within about 10 points of a new high. But, hpq appears to be one of the stocks leading the rush up, probably because it's starting from such a recent low. And with a clearly improving economy, everyone wins, at least all those who get on the Wall Street boat, or who still own their home. And there's still a lot of cash around, including a lot in government bonds that are paying about zero. I suspect that more and more people are now deciding to get back into the stock markets.
Do you still own those housing shares that you bough a few years ago near the bottom? Maybe even they are doing well by now. ;)
Yeah I was lazy enough to hold on to most of the homebuilder sharesI bought and now, finally, I'm in the black. If you calculated my ROI on this stuff, it's probably still negative, but at least I don't have a loss.
