Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of accused patent troll VirnetX (AMEX: VHC) jumped 12% in trading just before 1 p.m. ET after the company was upgraded by an analyst.

So what: Analysts at Craig-Hallum initiated coverage with a buy rating and a $50 price target. The market proceeded to have a panic attack, sending volume through the roof and the stock higher when it was down on the day.

Now what: Why should you care what Craig-Hallum has to say? You shouldn't really. The market has been grasping at straws with VirnetX and as a result the stock has been on a roller-coaster ride for the past year and this is just the latest case.

Apple (Nasdaq: AAPL) is calling more of the company's patents into question and companies making 4G phones aren't exactly knocking down the door to license the company's patents. I just can't get behind VirnetX right now and think today's bump will soon wear off.
