Strong earnings results this week from IBM and Intel have tech stocks in the midst of a nice rally.
Industrial bellwether International Business Machines and chipmaker Intel both posted profit ahead of analyst expectations, allaying fears that poor results last week from CNBC.com-parent General Electric might have been the harbinger of earnings disaster to come.
The Nasdaq index, the stock market's chief barometer of technology stocks, gained 2.7 percent in fairly heavy trading Wednesday and is up 7.7 percent from its 2008 low closing on March 10.
