Technology stocks rose for the third straight session Friday as investors welcomed revenue increases at Microsoft (MSFT) and Xerox (XRX), but jitters about higher interest rates kept the Dow and the broad Standard & Poor's 500 indexes flat.

The technology-focused Nasdaq Composite Index (search) rose 16.86 points, or 0.83 percent, to 2,049.77.

Declining issues had a 2-to-1 lead over advancers on the New York Stock Exchange as a surge in durable goods orders renewed worries that rates would head higher.

Blue chip stocks were lower for much of the day Friday as a report of strong durable goods orders in March fanned fears that the economy may be bouncing back fast enough for the Federal Reserve (search) to begin raising rates from 45-year lows.

The Commerce Department (search) said orders for manufactured goods rose by a robust 3.4 percent last month. The increase followed an even better 3.8 percent rise in February and surpassed the 0.7 percent rise expected by economists.

"We're in a transition phase with this market," said Stuart Freeman, chief equity strategist for A.G. Edwards & Sons. "For the first year of recovery, good news has been nothing but good news because investors weren't worried about the Fed raising rates. But when we get news like today ... it causes worry about when the Fed will come in to raise rates and by how much."

Investors have been skittish about higher rates for the past two weeks, particularly after Federal Reserve Chairman Alan Greenspan (search) gave two days of testimony in Congress this week that markets took to be a signal that interest rates could rise.

Other signs of economic strength such as jobs growth and higher consumer prices reinforced the concerns about higher rates, which could hurt stocks as well as bonds.

"I think the market's adjusting to the fact that the economy is gathering so much momentum. The question now is, will there by a shortage of labor?" said Kevin Gaughan, portfolio manager and equity strategist at Strong Financial Corp. in Milwaukee. "That's a sea change. Being an anticipatory creature, the market is looking ahead to the next issue."
