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 OYO Geospace (Nasdaq: OYOG) fell 10% today after the company released earnings.

So what: For the fiscal fourth quarter, OYO Geospace reported $32.8 million in revenue and $3.6 million in net income, or $0.56 per share. Analysts' expectations were much higher, however, expecting $41.9 million in revenue and $1.25 in earnings per share.

Now what: An earnings miss is never great for a stock, but this miss was by such a wide margin I'm surprised the stock hasn't fallen further. For the full fiscal year, revenue did grow by 35% and net income was up 111% so it isn't like the company is floundering in the current environment. Management pointed to normal variability in earnings for the weak quarter and said that backlog remained healthy.
