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: IntraLinks Holdings (NYSE: IL) shares jumped 10% in intraday trading after the company announced a follow-on public offering Friday.

So what: The company and certain stockholders will sell 9 million shares, plus a possible 1.35 million for over-allotment. It is not yet decided how many shares each party will sell.

Now what: After the company reported a loss in the third quarter and is now selling shares, I'm going to stay away from this one today. The bounce may be great in the short term, but I'm more worried about "certain selling stockholders" who may signal a downturn for the stock.
