We had a lot of big names trading up to new 52 week highs again today. The overall markets were pretty flat, with the DOW closing the day down 0.14%, the NASDAQ closing the day's trading up 0.04%, and the S&P ending the day a bit lower to finish today's trading down 0.28%.

Here are a few of the names that moved higher during the day to set new 52 week highs.

"We believe that the recent relative strength of tech stocks is the start of a longer term trend, not merely a flash in the pan," says Jim Oberweis and Dave Covas.

In The Oberweis Report, the money managers and small cap advisors explain, "Our confidence stems from the emergence of the next Killer Apps, which drive technology cycles because they change how we live our lives." Here, they make a case for technology and offer a trio of small cap favorites.

"During the 1980's and early 1990's, the personal computer was the Killer App. During the late 1990's, it was the Internet. During this decade – zilch. Until now. The next Killer Apps – video-on-demand and ubiquitous high-speed wireless connectivity – are coming.

According to a Dow Jones report yesterday, the decisions to three pending Star Scientific, Inc. (NASDAQ: STSI) summary-judgment motions in the company's patent-infringement lawsuit against Reynolds American Inc's (NYSE: RAI) R.J. Reynolds Tobacco Co. will be available on tomorrow.

The patent-infringement suit has been ongoing since 2001, when Star Scientific filed against Reynolds, alleging that Reynolds had violated the company's process to reduce the level of nitrosamines - a carcinogenic toxin - in tobacco.

Star Scientific's stock rose from $3.39 to $4.40 yesterday on the news the decisions had been reached, and could rise again significantly should those decisions go its way. Additionally, if Reynolds is ordered to pay a significant enough sum, the tobacco giant may decide to simply buy out Star Scientific rather than pay a hefty patent-infringement fine.
