YAHOO [BRIEFING.COM]: Challenged by thin volume, equities endured yet another day of lackluster action. After reaching lows during the first hour of trade, stocks staged a slow, session-long recovery. As a result, the major indices ended flat.

Healthcare was one of today's top performers. The space was lifted by
Coventry Health Care (CVH 42.04, +7.10) as it surged 20.3% after being acquired by Aetna (AET 40.18, +2.14) in a $7.3 billion deal. Other healthcare components received a lift from the acquisition as Bio-Reference Laboratories (BRLI 29.71, +0.31) gained 1.1% and Humana (HUM 68.23, +0.43) added 0.6%.

Technology stocks posted gains as the group's biggest component,
Apple (AAPL 665.15, +17.04), advanced by 2.6%. As shares marked a new all-time high above $665.00, the company achieved a milestone market cap of $623.14 billion. This made Apple the most valuable company in history. Competitors Hewlett-Packard (HPQ 20.09, +0.57) and Dell (DELL 12.56, +0.34) gained 2.9% and 2.8%, respectively. The two computer makers are scheduled to release their earnings later in the week.

Airline stocks outperformed after
Southwest Airlines (LUV 9.44, +0.31) announced a $10 increase in the price of nearly a third of its flights. Shares of the discount airline ended higher by 3.4%. Other carriers followed the announcement with fare hikes of their own. United Continental Holdings (UAL 19.45, +1.05) and JetBlue (JBLU 5.27, +0.21) jumped 5.7% and 4.2%, respectively.

The consumer discretionary sector underperformed with some of the biggest losses observed in homebuilder stocks. The group retreated after making a broad advance resulting from Thursday's positive new housing permit data.
KB Home (KBH 10.59, -0.45) was down 4.1% while NVR (NVR 811.59, -32.17) and DR Horton (DHI 18.41, -0.57) ended lower by 3.8% and 3.0%, respectively.

The telecommunications sector was the day's biggest laggard. Stocks within the space have been on a strong run recently and today's weakness appeared to be due to profit-taking rather than a sector-wide sell-off.
Sprint (S 5.11, -0.08) shed 1.5% and MetroPCS (PCS 9.91, -0.12) was off by 1.2%.

Lowe's (LOW 26.26, -1.61) fell 5.8% on heavy volume. Shares of the hardware retailer are under pressure after the company delivered disappointing results which showed both earnings and revenues misses, and lowered guidance. Competitor Home Depot (HD 56.57, -0.16) slipped 0.3%.

Best Buy (BBY 18.16, -2.11) slumped 10.4% after Hubert Joly was named as the new Chief Executive Officer. Shares of the technology retailer are under pressure as the board of directors steps up its battle with founder Richard Schulze over an attempted buyout. Best Buy will report earnings tomorrow before the bell.

It dipped again in the afternoon pit session but a rally heading into the close helped push prices up briefly into the black to a session high of $96.45 per barrel.
