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 silica producer U.S. Silica Holdings (NYSE:SLCA) fell as much as 10% today after the company released earnings.

So what: Revenue jumped 24% in the quarter to $129.8 million but that was short of the $134.6 million estimate from Wall Street. Earnings per share of $0.38 were $0.02 short of estimates as well, so the double miss is what investors were selling today.  

Now what: This looks like a case in which expectations just got ahead of the company because U.S. Silica is growing nicely. I'd be more concerned about falling margins on the bottom line, so watch that over the next few quarters. At 10 times earnings the stock is still attractively priced; I think this is a great entry point for investors eyeing the stock.
