YAHOO [BRIEFING.COM]: A modest advance by stocks put the S&P 500 at its best level in about 10 months, the Dow at its highest level in nearly four years, and the Nasdaq at its highest point in more than a decade, but gains were checked by some afternoon selling.

Consistent with recent sessions, early trade was relatively choppy as many market participants showed skepticism about the stock market's ability to keep climbing without consolidative activity following its climb in recent weeks -- the S&P 500 scored a 0.3% gain this week, booking its seventh weekly advance in eight.

Early headlines had little, if any, influence over the direction of broad market trade. As such, better-than-expected earnings from AIG (AIG 28.41, +0.42), Gap (GPS 22.57, -0.95), and JC Penney (JCP 41.72, -0.21) saw mixed reactions.

In a similar vein, there was hardly a reaction to economic data that featured an improvement in the Consumer Sentiment Survey for February from the University of Michigan to 75.3 from the 72.5 that had been posted in the preliminary reading. Economists polled by Briefing.com had expected, on average, that the Survey would improve to just 73.0. Released just minutes later, new home sales during January were said to have hit an annual pace of 321,000 units, which is down from the upwardly revised rate of 324,000 units set in the prior month, but better than the rate of 315,000 units that had been broadly expected.

Despite listlessness in the early going, stocks eventually worked their way higher. The move initially encountered resistance, but stocks were able to overcome it in a second attempt. That allowed the broad market to add incrementally to its multi-month intraday high. Although tech stocks traded with relative strength and settled with a 0.6% gain, the sector never really displayed the leadership necessary to drive a broad market rally.

Strength in the tech sector was partly offset by weakness in the highly influential Financial sector, which lagged for virtually the entire session and settled with a 0.4% loss.

As stocks appeared unable to extend their climb some participants opted to take some profits, dropping the S&P 500 to the flat line before it could find support.

Share volume this session was paltry, reflecting apathy among investors. The final tally on the NYSE was barely 640 million shares. Although volume trends have been low for several months, some question whether or not stocks can continue to climb if there isn't conviction among market participants.

Oil prices extended their climb again -- the energy component closed at a new multi-month high of $109.76 per barrel for a 1.7% gain. That move helped drive the CRB Index to a 0.8% gain for the day and 2.7% gain for the week. That stands as the CRB's best one-week performance of the past two months.

In the backdrop, the dollar dropped to a new two-month low against a basket of major foreign currencies. It was especially weak against the euro, which was quoted at $1.345 for a gain of about 0.6% by session's end.

Leading up to trade on Friday, stocks put together solid gains on Thursday. The effort came in the face of news that the European Union expects eurozone GDP for 2012 to decline by 0.3% instead of expand by 0.5%, as had been previously projected. 

Economic data was limited to news that initial weekly jobless claims remain near four-year lows. The latest tally totaled 351,000, which is unchanged week over week, and generally on par with the 355,000 initial claims that had been broadly expected.

There was only a morsel of domestic data released on Wednesday. It showed that existing home sales for January hit an annualized rate of 4.57 million units, which is shy of the rate of 4.63 million units that had been broadly expected. A significant downward revision to prior month sales also hurt the housing picture.

Europe remained in focus because of a few key manufacturing readings. The eurozone Manufacturing PMI inched up to 49.0 from 48.8 in the prior reading, but the sub-50 number still points to tighter activity. At 50.1, Germany's Manufacturing PMI was incrementally above that dividing line, but it was still down from the 51.0 posted in the prior month. France's PMI proved more impressive with its improvement to 50.2 from 48.5 in the prior month. China posted its latest Manufacturing PMI, which showed improvement to 49.7 in February from 48.8 in the prior month, but it still suggested that activity is contracting.

The CRB Index scored a 0.8% gain today. That helped fuel a weekly gain of 2.7%, which stands as the CRB's best one-week move in two months.

Oil has been a primary driver of the CRB's ascent. The energy component extended its climb into today's trade by closing at a new multi-month high of $109.76 per barrel for a 1.7% gain. 

In contrast, natural gas extended its decline. The energy component closed with a 2.5% loss at $2.69 per MMBtu.

Precious metals also closed with losses. Specifically, gold prices fell 0.6% to $1776.30 per ounce, while silver settled at $35.28 per ounce for a 0.7% loss.

Since U.S. markets were closed on Monday in observance of Presidents Day, trade this week started on Tuesday. Market participants were generally unenthused by long-awaited news that eurozone officials finally agreed to give Greece another bailout. As such, stocks eked out only an incremental gain.
