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 Chinese IT services company Camelot Information Systems (NYSE: CIS) were getting battered today, losing as much as 11% intraday trading on heavier-than-average volume.

So what: On Friday, Camelot's shares were popping after the company reported better-than-expected revenue and gave earnings guidance above analysts' estimates. Interestingly, though, shares lost most of Friday's gains and ended the day with a very meager return. The news today isn't quite as notable as Friday's but seems positive nonetheless. Goldman Sachs (NYSE: GS) maintained a neutral rating on shares and a $20.70 price target, while Barclays (NYSE: BCS) stuck with an overweight rating and a $23 price target.

Now what: Since the news for Camelot directly seems anything but bad, we're left to speculate on why investors may be running for cover. One possibility is the fallout from the blowup at Longtop Financial Technologies (NYSE: LFT). Last week, the company's shares were halted, and reports from Reuters today show the company's auditor (Deloitte Touche Tohmatsu) walking away, the SEC launching an investigation, and the company deciding whether to accept the resignation of its CFO. What does this have to do with Camelot? Deloitte Touche Tohmatsu is also Camelot's auditor, and it's a fellow Chinese company that serves the financial services industry. It could be that we've got a bit of guilt by association going on here today.
