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 U.S. Silica Holdings (NYSE: SLCA) jumped 10% briefly today after the company announced a share buyback program.

So what: Management said that the board of directors authorized a $25 million stock repurchase program to be completed over the next 18 months. This will be in addition to normal capital expenditures and will use available cash on hand.

Now what: Management thinks the stock is cheap and you can see why when you look at the numbers. The trailing P/E ratio is 13.1 and the forward P/E ratio is just 5.8, an extremely low valuation. Add to that the fact that the company has crushed earnings estimates in the last two quarters and it looks like a good use of cash. I think this will be a catalyst for the stock moving higher, especially if the good performance continues.
