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 insurance software vendor Ebix (Nasdaq: EBIX) were minding their own business on a humdrum day, until all hell broke loose and the stock fell more than 26% on truly massive trading volume in the early afternoon.

So what: This stock suffered an entirely inexplicable fall a couple of weeks ago, but this time there's a real driver behind the action. A scathing three-part article that eviscerates Ebix for being overpriced and possibly fraudulent hit the news feed just as the panic-selling started, showing that investors were taking that message to heart.

Now what: I'd think twice before acting on that damning report. For one, the articles point to CEO Robin Raina as a liability while our own Motley Fool Pro analyst team sees him as an asset, and the Rule Breakers team calls him a successful game-changer. But give the report a read and make the call yourself. Keep in mind it was written by an anonymous writer who disclosed a short position on Ebix and has every intention to profit from whatever market moves the article might trigger.
