HP shares surged by more than 7 percent, or $1.69, today to $25.10, mainly on a positive report on the state of its personal computer business from the market research firms Gartner and IDC.

As I noted yesterday, HP saw its share of the global market grow fractionally, according to the reckoning of Gartner, at the expense of Dell, Acer and Asus, while China-based rival Lenovo grew even more. IDC saw similar results, and both research houses were surprised to see the overall market grow in the first quarter of the year where a market decline had been expected.
