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 SonoSite (Nasdaq: SONO) exploded 27% higher today after the company agreed to be bought out by Fujifilm Holdings.

So what: Fujifilm will pay $54 per share, or $995 million, for the company to expand its reach in the health-care business. The board of directors has approved the transaction, and by all accounts it looks very likely to go through.

Now what: Since shares are trading very close to the offer price of $54, I don't see any reason not to cash out your shares today. If you hold, you're speculating on a higher offer and risking the downside of a deal not going through. With the holiday season approaching, I would take the 27% bump and run.
