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: Small-cap uranium miner Uranium Resources (Nasdaq: URRE) experienced heavy volatility in early Wednesday trading, as the stock continued to see unusually high trading activity.

So what: Uranium Resources' shares popped 10% at the opening bell, only to plummet quickly back down. At the time of this writing, the stock is off 5% on triple the average volume. Of course, Uranium Resources surged 30% on no apparent news yesterday, so today's emotion-fuelled roller coaster should come as no surprise.

Now what: With financials that bleed red and a beta of 3.5, Uranium Resources exhibits typical stomach-churning, penny-stock madness. For those bullish on a nuclear renaissance in the U.S, Cameco (NYSE: CCJ) and USEC (NYSE: USU) simply offer bigger and safer ways to bet your convictions. While Uranium Resources has some tempting get-rich-quick allure, it's too risky for most investors.
