For once, a broad-based rally that doesn't come with qualifiers. Well, except for the lousy volume.

Perhaps the surprisingly good weather in the Northeast this weekend has folks freshly scrubbed and confident today, as all major indices at midsession were well into the green, led by buying in the technology sector.

The

Nasdaq Composite Index was rallying, up 146, or 4.6%, to 3351, and the

Dow Jones Industrial Average had gained 150, or 1.5%, to 10,449, while the

S&P 500 was up 25, or 1.8%, or 1403. The small-cap

Russell 2000 was up 10, or 2.1%, to 467.

Some expected a negative reaction from this morning's release of the

Consumer Confidence Index, which rose to 144.4 in May, a four-month high after falling to a revised 137.7 reading in April. The survey demonstrates that job security and wage growth are more than offsetting the decline in stock prices in the mind of consumers, and analysts worry that the

Fed may remain in attack mode in its efforts to slow the economy.

Regardless, traders say that investors are balancing those concerns against the belief that the technology sector has been wrecked enough to provide a good buying opportunity.

Big-cap tech stocks are leading the way, including the

Nasdaq Stock Market's

most active,

Cisco

(CSCO) - Get Report

, up 2 11/16 to 57 5/8 on 24.3 million shares;

Nextel Communications

(NXTL)

, up 9.7%; and

Adobe Systems

(ADBE) - Get Report

, up 9.4%.

Major technology indices were strong, including the

Philadelphia Stock Exchange Semiconductor Index

, gaining 6.8%, and the

Nasdaq Telecommunications Index

, up 6.3%. New

Lehman Brothers

analyst Dan Niles transferred a lot of his coverage from his old shop,

Robertson Stephens

, and reiterated support of computer and chip stocks overall this morning.

TheStreet.com Internet Sector

index was up 37, or 5%, to 790, helped by the likes of

eBay's

(EBAY) - Get Report

6.6% gain and a 6.3% advance in

Yahoo!

(YHOO)

.

As with all rallies, this one provokes traders to question whether it will sustain itself, especially with worries about the Fed, and the market's recent tendency to quickly give back what it has gained.

"People saw opportunities and then took them," said Randy Billhardt, co-head of block trading at

PaineWebber

. "Certainly, the Nasdaq had been in oversold territory, and we're seeing strength there and in the financials, but there's not a lot of oomph behind the move."

It has investors thinking that the market may be in for a week similar to last week, where a day of mostly positive action alternates with a day of dreary, ugly selling. Already, there's a couple of important economic reports in the market's way this week, including the

National Association of Purchasing Management's

Purchasing Managers' Index, an important survey of manufacturing sentiment, and the May

employment report, due out Friday.

"People had a three-day weekend to look at prices and see some good, long-term values, and say, 'Let's go after them,'" said Allan Meyers, portfolio manager of the

Kent Growth & Income Fund

in Grand Rapids, Mich. "But as to whether it can hold these gains now, I'd say no. I think we still have some more churning to do."

The lack of conviction is supported by the lack of volume and some sector weakness. Strong sector advances include the commodity-related stocks, such as natural gas companies, and the brokerages, which were hosed last week after reports that

Goldman Sachs

(GS) - Get Report

may miss second quarter earnings estimates. The

American Stock Exchange Broker/Dealer Index

gained 2%.

The

American Stock Exchange Natural Gas Index

rose 1.9%, and the

Philadelphia Stock Exchange Oil Service Index

rose 1.3%.

The

Morgan Stanley Consumer Index

was lately down 0.3% in lackluster trading.

Sara Lee

(SLE)

had risen earlier but lately was off 1/4 to 18 5/16, after announcing plans to divest

Coach

leather and other businesses to focus on food, beverage and household products.

The

American Stock Exchange Pharmaceutical Index

was down 1.1%, and the

American Stock Exchange Tobacco Index

lost 2.1%.

"Across the board, there appears to be some selling of the old growth companies," said Ned Riley, chief investment strategist at

State Street Global Advisors

. "The health care, beverage, restaurant chains are weaker in face of the estimate of Fed hikes based on the consumer confidence survey."

The

Dow Jones Transportation Average

was up strong, gaining 1.8%, while the

Dow Jones Utilities Average

was down 1%.
