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 gold mining and exploration company Golden Star Resources (AMEX: GSS) jumped 10% late in trading as gold hit a new high.

So what: With gold hitting a record today, it's no surprise that Golden Star and other gold miners are rising. Miners are a leveraged way to invest in gold, and when prices rise it becomes even more profitable for their operations.

Now what: There wasn't anything specific to Golden Star driving the move today, so it's all about the price of gold. With uncertainty around the world, there's no telling when gold is going to stop making new highs, and if you're bullish there's no need to cash out here. If you're a buyer, there may be better opportunities to get in if the stock pulls back in coming days after today's exuberance wears off.
