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: Uranerz Energy (AMEX: URZ) shares jumped 14% in trading today as uranium miners traded higher.

So what: Uranium stocks have traded higher in the past month as investors speculate that U.S. nuclear plants will need to find a new source of uranium. A program to purchase uranium from Russia is ending in 2013, so domestic mining sources like Uranerz appeal to some investors.

Now what: Technical traders and momentum traders have moved into this stock, heavily pushing volume more than three times its normal levels today. I may miss out on a move, but this Fool doesn't have the guts to play a trading game in a company without revenue. I'll sit out until I see some sales and earnings before getting hyped about Uranerz, even if I miss the boat on a trader's dream.
