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 metals explorer and producer Gold Resource (AMEX: GORO) lost some of their shine today, falling as much as 10.3% on above-average trading volume.

So what: After rising relentlessly throughout August, gold prices fell by more than $100 per ounce today. What's worse, Gold Resource actually digs up a lot more silver than gold, and you may have noticed silver prices plunging even steeper than gold today.

Now what: Crashing silver prices notwithstanding, Gold Resource is taking a much harder beating than silver peers Silver Wheaton (NYSE: SLW), Silver Standard Resources (Nasdaq: SSRI), and Pan American Silver (Nasdaq: PAAS). That's because Gold Resource's management team looks anything but sterling -- a fact that has imparted a one-star CAPS rating on this stock amid a sea of more respectable competitors.
