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 Demandware Inc. (UNKNOWN:DWRE.DL) rose 10% to start the week following speculation it could be a takeout target.

So what: With shares of Demandware having drifted downward in recent weeks despite turning a narrower-than-expected first quarter loss earlier this month,, FBR Capital's Daniel Ives recently suggested would do well to acquire Demandware for its enterprise cloud commerce solution.

Now what: Still, Demandware isn't exactly cheap, trading around 16 times trailing 12-month sales and 340 times next year's estimated earnings, and even that's a big premium to pay for Salesforce, which itself is still striving to achieve sustained profitability. While such a deal could certainly fall into place, don't count on it as a crucial part of your investing thesis. For now, I'm perfectly happy continuing to watch Demandware from the sidelines.
