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 enterprise software maker Lawson Software (Nasdaq: LWSN) jumped as much as 13% today on buyout buzz.

So what: Last Tuesday, Reuters reported that Lawson had hired Barclays to explore strategic alternatives including a sale, and on Friday an offer came to fruition. Infor Global Solutions and Golden Gate Capital have offered $1.8 billion, or $11.25 per share, which was actually below Friday's closing price.

Now what: The stock is trading at $12.25 as I am writing, so the market is definitely expecting either an increased offer or a competing bid. SAP (NYSE: SAP) and Oracle (Nasdaq: ORCL) would be two potential bidders in the enterprise software space, but so far there is only speculation of a bid. It's a little risky to be buying today with only speculation floating around. If you're looking for a place to cash out, though, this could be a great time to get out without having to risk losing some of the "rumor" premium if another offer doesn't come in.
