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 accounting software maker Advent Software (UNKNOWN:ADVS.DL) dropped today by as much as 12% after the company said it will not pursue a sale.

So what: Reports that Advent was potentially considering a sale sent shares higher last week on hopes that the company could be acquired by a private equity firm. At the time, there was reportedly a large gap between what Advent was seeking and what prospective buyers were bidding. Today, Advent said it would continue on as an independent company.

Now what: CEO Pete Hess said the company went through a "thorough process" to evaluate the various strategic alternatives with the assistance of Qatalyst Partners, which served as Advent's financial advisor. Wilson Sonsini Goodrich & Rosati also served as legal counsel throughout the process. Hess said the board believes that shareholder value can be maximized under Advent's current strategic plan.
