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 communications security specialist VirnetX Holding (AMEX: VHC) let their actions do the talking today, rising as much as 12.1% on heavy volume.

So what: Analyst firm Cowen & Co. just started following VirnetX with a "buy" rating and a price target more than 40% above last night's closing price. Cowen sees the company collecting handsome paychecks as LTE networks become commonplace, catapulting VirnetX out of its current "pre-revenue" status.

Now what: Cowen basically equates VirnetX in the 4G era to the patent treasures of Qualcomm (Nasdaq: QCOM) in the 3G age. That supposed stranglehold on key LTE patents would make VirnetX a takeover target or at the very least an absolute cash machine. Mind you, the stock has gained a staggering 1,700% over the past year and a half amid speculation on the value of its patents, and the courts still have to work out a few lawsuits to settle the matter. Depending on the final outcome in suits filed against Apple (Nasdaq: AAPL), Cisco Systems (Nasdaq: CSCO), and many other tech titans, buying VirnetX today could be the best investment you ever made -- or akin to burning dollar bills on a bonfire.
