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 staffing company TrueBlue (NYSE: TBI) were sent packing today as the market kicked shares 11% lower.

So what: Deutsche Bank downgraded TrueBlue to hold today as concerns about a weak economic recovery and employment led it to cut estimates. TrueBlue isn't the only one being beaten up today. Competitors Manpower Group (NYSE: MAN) and Kforce (Nasdaq: KFRC) are among the companies feeling the market's wrath.

Now what: Staffing agencies are in a tough position right now as the economy sputters. They provide a valuable service for companies that don't want to go out and hire full-time workers, but if the economy doesn't improve, no one will hire at all. I am going to stay out of these stocks right now; value stocks that pay dividends are a safer way to invest in this uncertain environment.
