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 oil and gas explorer TransGlobe Energy (Nasdaq: TGA) experienced heavy volatility today on above-average volume.

So what: TransGlobe opened the trading day up nearly 13% only to pare most of those gains quickly. There doesn't seem to be any company-specific news driving the activity, but given today's big energy price moves, it's no surprise that the small and speculative TransGlobe is receiving some trading attention.

Now what: The shares remain best suited for less risk-averse investors. For the uninitiated, TransGlobe focuses its exploration in politically fickle Egypt and Yemen, which has naturally given Mr. Market plenty of reasons to worry. Of course, with the stock down about 25% year to date, more enterprising Fools might want to look into the possibility that he's worrying a little too much.
