Electronic Arts Inc.

Electronic Arts Inc. A disappointing outlook from the video game publisher sent its shares sharply lower, a sign that significant cost cuts and layoffs have not ended the company's slump.

The company, whose games include the popular "Madden" series and "Mass Effect 2," said Monday it narrowed its net loss in the last quarter even as game sales declined. It blamed the revenue falloff on having fewer titles than it did in the 2008 holiday period. EA also cited weak sales in Europe, which accounts for about a third of its revenue.

The results for the October-December period were not a surprise, because EA had warned in January it would miss forecasts, leading analysts to lower their estimates.

But the company gave a forecast below Wall Street's expectations for the current quarter. CEO John Riccitiello said in a conference call with analysts EA decided to be "a little bit more conservative" than others that have given guidance for the year.

Shares of EA, which is based in Redwood City, Calif., fell $1.48, or 8.5 percent, to $16 in extended trading after the earnings report.

CVS Caremark Corp. One of the nation's biggest drugstore operators said its profit rose 11 percent in the fourth quarter as results improved for its pharmacy benefits management business.

CVS shares rose $1.65, or 5.3 percent, to close at $33.72.

Revenue grew 7 percent to $25.82 billion from $24.14 billion but fell short of Street estimates of $26.22 billion.

The company did not disclose any new contract losses for its Caremark pharmacy benefits management business and sought to reassure analysts that the billions in contracts it has lost were a one-time problem.

Hartford Financial Services Group The insurer said it was profitable in the fourth quarter as its life and property-casualty businesses both improved.

The Hartford, Conn.-based company earned $557 million, or $1.19 per share in the final three months of the year. That compared with a loss of $806 million, or $2.71 per share, a year earlier.

Excluding investment gains and losses, core earnings rose to $689 million, or $1.51 per share, versus a loss of $208 million or 72 cents per share a year ago.

Results exceeded Wall Street's expectations for earnings of $1.40 per share, according to a poll by Thomson Reuters.

Shares lost 42 cents, or 1.8 percent, to $23.04 in after-hours trading. The stock lost 7 cents to $23.46 in the regular session.

Nasdaq OMX Group Inc. Eroding market share and weaker trading volumes hurt fourth-quarter revenue, but sharply lower taxes and fewer charges helped the global exchange operator report better-than-expected profit growth.

Nasdaq OMX Group's revenue fell as trading activity declined and the exchange operator continued to face market competition. Rival trading platforms launched in recent years have eaten away at market share held by long-standing exchange operators like Nasdaq OMX and NYSE Euronext. The added players also have pressured fees generated from handling trades.

During the fourth quarter, 20.6 percent of U.S.-listed equities trading volume was executed on Nasdaq OMX Group's trading platform, down from 29.2 percent in the final quarter of 2008. Total volume fell 36 percent to 126.1 billion shares.
