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 liquefied natural gas (LNG) company Cheniere Energy (AMEX: LNG) sank as low as 11% in intraday trading Wednesday on extraordinarily high volume.

So what: At the time of publication, 4.5 million shares of Cheniere have already changed hands, versus its average volume of roughly 3 million shares. It's tough to pinpoint exactly what's driving today's heavy selloff, but when you consider the stock's mammoth 220% run-up over the past six months, one-day double-digit corrections shouldn't come as a huge surprise.

Now what: Investors should keep today's move in proper perspective. Without any news from the company, I'm chalking the share price plunge up to the normal short-term craziness associated with speculative stocks such as Cheniere. Of course, given its negative earnings, high debt load, and red-hot stock price, Cheniere isn't exactly the most prudent long-term investment, either.
