Worries about a potential snag in a deal to get the Greek debt situation under control, as well as uncertainty about tonight's State of the Union address and some mixed earnings news, combined to send stocks mostly lower today. Just before 2:15 p.m. EST, the Dow Jones Industrials (INDEX: ^DJI) were down 44 points to 12,665, while the S&P 500 (INDEX: ^GSPC) lost three points to 1,313.

As Fool analyst Dan Dzombak covered this morning, earnings played a major role in the Dow's decline. Let's turn to some other stocks making moves.

The tech contingent of the Dow saw mixed performance. IBM (NYSE: IBM) rose about 1% in mid-afternoon trading. The company, which announced positive results last week, seems on pace to reach its target of $20 per share in annual earnings by 2015. Intel (Nasdaq: INTC) also rose by nearly 1%, setting another four-year high for the stock as signs continue point to a turnaround in the chip sector.

But Microsoft bucked the trend, falling more than 1% after it decided to pull the plug on its annual MIX developers conference. Speculation also arose that the company may phase out its Points system for Xbox Live.

Elsewhere, Coca-Cola (NYSE: KO) lost about 1%. The company is expected to raise its dividend next month, and if it does, it would mark the 50th consecutive year that Coca-Cola has done an annual dividend increase. The company also announced a bottling agreement with the Rwandan unit of Heineken.
