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 Great Basin Gold (AMEX: GBG) were shining today, jumping 10% in intraday trading.

So what: There isn't any solid news out today, but volume is nearly double the three-month average, indicating someone is buying big-time. This doesn't look like a short squeeze since short interest has actually been down recently, so a move so large is a bit peculiar.

Now what: It looks like a recovery day after a rough three months for Great Basin Gold's shares. The price of gold itself isn't driving the move, and if there's no news I'm left scratching my head. No reason to change your investment thesis today, and I'm wary of jumping in on a random move like this.
