This was no manic Monday. Trading was quiet today as investors took stock of recent gains and tried to figure out what to do next. Major proxies squeaked into the green after bouncing around narrow trading ranges for most of the session.

After tacking on hefty gains in the prior two trading sessions, many investors were pleased to see the

Nasdaq Composite Index

and the

Dow Jones Industrial Average

hang in there today.

The Comp ended the day up 8.38, or 0.2%, to 3821.76 after rocketing up 412 points over Thursday and Friday. The Dow Jones clung to its gain of 20.54, or0.2%, to end the session at 10,815.30 after pocketing 272 points at the end of last week.

"You've got to be impressed by the market's ability to hold Thursday and Friday's gains," said Todd Clark, head of listed trading at

W.R. Hambrecht

adding that he had expected to see much more profit-taking. "We came so far and then people go have a weekend and start reassessing the long term. That has not occurred, that is pretty important. It looks like this market wants to work its way higher," he said.

Clark said it is worth keeping an eye on the ongoing

Supercomm 2000

technology conference in Atlanta where corporate announcements could originate this week.

Today, it was the tech bellwethers that led the way higher.

IBM

(IBM) - Get Report

rose 3.3%, while

Ariba

(ARBA)

hopped 14.2%.

The broader

S&P 500

was under pressure, losing 9.63, or 0.7%, to 1467.63, while the

edged up 0.26, or 0.1%, to 513.29. Despite the strength of a number of tech bellwethers today,

TheStreet.com Internet Sector Index

lost ground, down 15.16, or 1.6%, 930.26.

are planning to introduce computer systems based on the processor.

Human Genome Sciences

(HGSI)

rose 7.1%, after

Lehman Brothers

lifted the stock to long-term buy from long-term accumulate. The

Nasdaq Biotechnology Index

rose 2.8%. Though it remains more than 25% off its March highs, the volatile measure managed to tack on 18.4% in the last week's holiday-shortened trading, rallying with the broader market.

Transportation stocks were lower, including some downside from the airlines. The exceptions to the rule included

KLM Royal Dutch Airlines

(KLM)

up 5.4% and

British Airways

(BAB) - Get Report

up 3.8%, after news reports said the two were exploring a possible merger. The

American Stock Exchange Airline Index

was down 0.8%, while the

Dow Jones Transportation Average

lost 1%.

Stocks in the oil sector were also mixed. Oil service company

upgraded it to top pick.

Hallibuton

(HAL) - Get Report

slid 5.6%. The

Philadelphia Stock Exchange Oil Service Index

fell 3.3%.

Crude oil prices dropped amid a flurry of comments about oil output which confused traders.

OPEC

president Ali Rodriguez reiterated the cartel will raise output if the 20-day average price of a basket of seven crudes rose above $28. July crude last traded at $29.65 a barrel, sliding 70 cents on the day. The

American Stock Exchange Oil & Gas Index

edged down 0.3%.

Looking to the week ahead, some market watchers expressed doubt about how much upside is left in the market. There are a couple of news events that might impact the market later this week, said Ricky Harrington, chief technical analyst at

Wachovia Securties

in Charlotte, North Carolina. Harrington noted Friday's

Producer Price Index as well as an interest rate decision from the U.K.

Though he thinks the market may move above last week's levels, he said upside is fairly limited.

"We are going to run into some trouble as the Dow approaches 11,000 and the Nasdaq moves to 4000. Those are two very key levels. Fundamentally the market is still overvalued and psychological factors," will also be an issue.
