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 Dawson Geophysical (DWSN -1.47%) fell 14% today after the company warned that fourth-quarter results may not meet expectations.

So what: Management reminded investors that results for the fiscal fourth quarter will be lower than last quarter due to low utilization of its crews. "Project readiness issues" were blamed for much of the slowdown in the quarter, although exact revenue and earnings figures weren't given. 

Now what: This shouldn't come as a huge shock for investors, and it appears that demand is already starting to pick up. Dawson expects there will be enough work for 13 crews in the U.S., and one crew in Canada this winter season, and it has maintained staffing levels to be able to keep up with a pickup in business. I see this as a short-term hiccup and a great buying opportunity for investors looking to get into shares today.
