This week's rumor round-up: Lam Research close to sale?

Heading to Memorial Day, there's certainly no moratorium on the number of talked about potential deals. Receiving a fair amount of attention over the last few days include the companies below. There's more, of course, but hey, it's a three-day weekend.

LAM RESEARCH CORPORATION (NASDAQ: LRCX)

This supplier of tools that makes microchips keeps seeing its stock move up. Up about 13% over the last few months. And it may be more than speculation that it will soon be acquired. Investors looking for a deal are snapping up equity calls, some are then selling them, and keeping both eyes on the stock price. Others are looking out to see which private equity firms or "strategic" buyers come calling.

AMDOCS LIMITED (NYSE: DOX)

As Alltel Corporation (NYSE: AT) goes, so goes Amdocs? Well, not quite. Yes the Alltel sale has pushed Amdocs' stock upward. Some say this maker of software products for telecom services firms may want to continue to go forward by themselves. But that hasn't stopped that list of potential buyers from being passed around. Best bet: International Business Machines Corporation (NYSE: IBM).

CIRCUIT CITY STORES (NYSE: CC)

Again, here we go: Is it going to take a buyout? (Read: private equity buyer.) Or a miracle? (Read: new management) There are profit warnings. (Read: red flags everywhere) The stock is in miserable shape. (Read: cheap) Tough competition. (Read: Wal-Mart Stores Inc (NYSE: WMT)). Think there's a book to be written about all of this? (Read: who'd want to?).

APPLEBEE'S INTERNATIONAL INC (NASDAQ: APPB)

Food for thought. Kangaroo Holdings wants to buy OSI Restaurant Partners Inc (NYSE: OSI). Not surprisingly, Applebee's stock goes up. Are they cooking up a sale price for themselves as they "evaluate" offers? You betcha.

PALM INC (NASDAQ: PALM)

Going, going...almost gone. Even we're beginning to tire of this one. But it never gets old if you like to watch. Now, they're canceling conferences. The CEO is selling shares. The CFO has a bad back. Come on! The latest product review - Palm Treo 755p - is terrible. Market share is going down the tubes. R&D? Forgetaboutit. Sound like a company on the go? Right. Right into someone else's lap. And to think what they once were. Great job all around, everybody.
