Blue chips lost their bid for a perfect week on Wall Street as profit-takers emerged on an options-expiration Friday. Tech stocks managed their sixth consecutive gain.

The

Dow Jones Industrial Average

fell 21.28 points, or 0.2%, to 10,471.91. The

S&P 500

lost 1.80 points, or 0.15%, to 1189.28, while the

Nasdaq

rose 3.84 points, or 0.19%, to 2046.42. The 10-year Treasury was down 3/32 in price to yield 4.12%, while the dollar firmed against the euro and the yen.

All three major indices posted strong gains for the week and sit well above their 50- and 200-day moving averages. For the five sessions, the Dow was up 331 points or 3.3%, the S&P 500 rose 35 points or 3.1%, and the Nasdaq added 69 points, or 3.5%.

"We're above technical strength, which leads me to believe we've got some more upside to go," says Paul Nolte, director of investments with Hinsdale Associates. "The big number to focus on next week will be the durable goods numbers, which will help us define if we're in a soft spot or not. The market is going to be fairly volatile next week."

About 1.62 billion shares changed hands on the

New York Stock Exchange

Friday, with decliners beating advancers by a 9-to-7 ratio. Volume on the Nasdaq was 1.50 billion shares, with decliners outpacing advancers 8 to 7.

"There

was some well-justified profit-taking, which should be totally expected," says Joe Liro, an equity strategist with Stone & McCarthy Research Associates. "We got a very impressive week. There's still some upside to go, but I don't think we'll get new highs for the year."

Oil fell again Friday. The June crude contract, which lost 2.9% over the week, closed 12 cents lower at $46.80 a barrel. On Monday, the July contract becomes the front contract for the month.

Federal Reserve

Chairman Alan Greenspan addressed the topic of energy to the Economic Club of New York, saying high oil prices could temper economic demand and serve as their own brake.

"This emerging condition could encourage the buildup of enough of an inventory buffer to damp the price frenzy," said Greenspan. "Since the end of 2003, the rise in the value of imported oil -- essentially a tax on U.S. residents -- has amounted to about three-fourths of a percent of GDP. The effects were far larger in the crises of the 1970s. But, obviously, the risk of more-serious negative consequences would intensify if oil prices were to move materially higher."

Homebuilding companies took a hit after Greenspan said there's no national housing bubble, despite some localized froth. He also commented that housing prices are unlikely to decline.

Tech investors saw the semiconductor industry book-to-bill ratio for April Thursday night. The report, which measures shipments against new orders among chip suppliers, came in at 0.8, meaning $80 of new orders was received for every $100 of product shipped.
