What: Shares of job matchmaker Monster Worldwide (NYSE: MWW) are roaring higher today by upward of 23% on reports that the company has attracted potential buyers.

So what: Two months ago, Monster made it clear that it was interested in selling itself, as CEO Sal Iannuzzi said the company was "pursuing all strategic alternatives" and subsequently retained financial advisors to help evaluate its options. Reuters is reporting that disruptive professional networker LinkedIn (NYSE: LNKD) and private equity firm Silver Lake Partners are among potentially interested parties.

Now what: According to the report, Monster is planning on sending out some financial details to possible buyers by the end of next week, giving shareholders hope that a deal may be on the horizon. While Monster's share of the online recruitment market is estimated at 23%, notably higher than LinkedIn's roughly 16%, the old model of posting job ads is ripe for disruption from social media players like LinkedIn. Monster's top line is indeed heading the wrong way as sales slipped 6% last quarter to $246.1 million, as LinkedIn's sales just doubled to $188.5 million. Both Monster and LinkedIn opted not to provide any official commentary to the speculation.
