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 producer Gold Resource (AMEX: GORO) lost their shine today, falling as much as 14.7% in extremely heavy morning action. The stock has recovered some to stabilize at a smaller 4% drop.

So what: The precious-metals sector at large is hardly suffering today, as producers from Silver Wheaton (NYSE: SLW) to NovaGold Resources (AMEX: NG) are crushing the market amid rising gold and silver prices on the spot market. Gold Resource is bucking the upward trend because Barron's shone a spotlight on the company over the long weekend -- and the stock came out looking like a lump of coal.

Now what: Barron's highlighted management's lavish expenses and some creative accounting practices, along with a lack of proven gold reserves. "The Reids use a measure called 'mine gross profit' that ignores all construction and overhead costs," and has never reported positive GAAP operating cash flows, according to the article. Gold Resource trades for nearly 50 times trailing sales and 24 times book value, and I'm only surprised that it hasn't attracted more than an 11% short interest. I'm no gold bug, but I'd sleep far better having invested in a solid performer such as Silver Wheaton rather than Gold Resource.
