Stocks jumped on Thursday as expectations of reassuring quarterly results from bellwethers including Google lifted technology shares, while JPMorgan's better-than-expected profit added to bank stabilization hopes.

Google is scheduled to post quarterly results after the bell, and its stock was up 3 percent at $391.03. Hewlett-Packard , up nearly 5 percent, was the Dow's second top boost, behind IBM , up 1.7 percent to $100.49.

Also boosting sentiment were stronger-than-expected quarterly results from Harley-Davidson Inc that pointed to some stabilization in consumer spending. The motorcycle maker's shares rose 8 percent to $18.51.

The Dow Jones industrial average <.DJI> rose 61.72 points, or 0.77 percent, to 8,091.34. The Standard & Poor's 500 Index <.SPX> climbed 10.92 points, or 1.28 percent, to 862.98. The Nasdaq Composite Index <.IXIC> gained 35.60 points, or 2.19 percent, to 1,662.40.
