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: 51job (Nasdaq: JOBS) dropped 15% in intraday trading today after a negative mention in an investment report.

So what: Zacks published a report on mysmartrend.com on the human resource and employment services industry. 51job was criticized for its P/E ratio of 43 times, along with On Assignment (Nasdaq: ASGN) for its P/E of 69 times, Heidrick & Struggles International (Nasdaq: HSII) for its P/E of 65 times, Robert Half International (NYSE: RHI) for its P/E of 46 times, and TrueBlue (NYSE: TBI) for its P/E of 28 times.

Now what: Disappointing jobs reports and economic news are clouding the outlook for the industry in the United States. 51job focuses on the much stronger Chinese market, however. While a weaker U.S. economy could slow jobs growth in China, investors should think twice before laying off 51job's stock.
