International Business Machines Corp. (NYSE:IBM) has weathered the storm about the SEC investigation into its first-quarter earnings disclosure pretty well. Shares of Big Blue have jumped 32 percent over the last six months, keeping pace with other tech heavyweights such as Microsoft Corp. (NASDAQ:MSFT) (up 38 percent) and Hewlett-Packard Co. (NASDAQ:HPQ) (up 38 percent).

Bloomberg News reports The company said last January that it was facing a formal SEC investigation, which makes the stock performance all that more remarkable. Still, you can bet that the earnings call following the release of earnings on January 18 will be lively. I'm sure analysts will be interested to hear the company's thoughts on technology spending and any update on the investigation.

Wall Street is skeptical that IBM shares will go much higher. Their average target price is $99.67,about where the shares are trading today. Analysts are expecting the Armonk, NY-based company to have earnings of $2.19 on revenue of $25.66 billion, according to Thomson Financial.

IBM is a bellwether for both the tech sector and overall confidence in the economy. Since becoming the head of IBM in January 2003, Sam Palmisano wisely decided that IBM should focus on businesses. He got rid of the underperforming notebook computer division and acquired the consulting business of PricewaterhouseCoopers LLC. Some critics of the company have claimed -- wrongly I think -- that IBM makes its hardware and software hard to use so that customers need to hire an IBM consultant to help them out.
