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 fuel logistics provider World Fuel Services (NYSE: INT) were getting dumped today, falling as much as 12%, after missing revenue expectations in its quarterly report.

So what: Adjusted earnings per share of $0.73 actually beat estimates of $0.69, but that was down from the total a year ago of $0.81. Revenue grew only 5% from the previous year, to $9.94 billion, missing estimates of $10.22 billion. CEO Michael Kasbar put a positive spin on the full-year results, saying that, "despite a stagnant market, we posted record revenue, gross profit, and volume while completing two strategic acquisitions."

Now what: World Fuel's acquisitions should help it continue to grow, but this company is primarily dependent on volatility and increases in oil prices. With the slowdown in Europe, modest recovery in the U.S., and energy markets seemingly stable, I wouldn't expect anything more than modest returns in the near future.
