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 services company TrueBlue (NYSE: TBI) are shooting up 14% today following its second-quarter earnings report.

So what: Apparently the unemployment picture isn't as dire as the U.S. Labor Department would have you believe -- at least if you consider the figures TrueBlue just reported. For the quarter, the blue-collar staffer reported a profit of $0.20 on revenue of $320 million. While revenue was in line with consensus estimates, its profit beat estimates by $0.02. More importantly, the company sees "third-quarter growth accelerating," in its own words. TrueBlue's third-quarter revenue guidance of $360 million to $370 million and an EPS projection of $0.27-$0.32 easily trumps current Wall Street estimates.

Now what: Much of the staffing sector appears relatively inexpensive. Manpower (NYSE: MAN) is valued at just 12 times forward earnings with a PEG ratio below 1. Likewise, Kelly Services (Nasdaq: KELYA) currently trades below book value despite a PEG ratio below 1 and a forward P/E of only 9.5. TrueBlue has the most aggressive valuation of the bunch, but it appears to be growing the quickest. It also has a cash-rich balance sheet free of debt, which its competitors can't claim. After today's pop, I wouldn't say the company's a bargain anymore, but it definitely deserves a place on your watchlist.
