DOW JONES & COMPANY (NYSE: DJ)

Could it happen? Could News Corporation (NYSE: NWS) pull its offer? They could, and the fear is absolutely there. That's why the stock has fallen. For one, the Bancroft family, which controls the majority of Dow Jones' shares, hasn't formally accepted Rupert Murdoch's $5B, $60 a share offer. And no one else has come forward with a competing bid. But it does seem that both sides are moving together in the same direction. Okay, but somebody should make up their mind -- either way -- and stop fiddling around.

EXPEDIA INC (NASDAQ: EXPE), IAC/INTERACTIVECORP (NASDAQ: IACI)

Barry Diller is back at it. The chairman and CEO of IAC/InteractiveCorp, who is also chairman of the board and a senior advisor to Expedia, is working to take online travel firm Expedia private at $30 a share. Part of any deal will involve Expedia's TripAdvisor being spun off with about 400 jobs being lost in that shuffle.

PENN NATIONAL GAMING INC (NASDAQ: PENN)

After many, many laps around the track, this race is over, as race track and casino operator Penn agreed to be acquired today by Fortress Investment Group LLC (NYSE: FIG) and private equity firm Centerbridge Partners. All cash, baby, in a deal worth $8.9B that includes $2.8B of assumed debt. Everyone to the Winner's Circle.

This is the week that was, or, actually, wasn't. Lots of talk in lots of industries, but not much action. Here's a sampler...

JEFFERIES GROUP, INC. (NYSE: JEF)

The investment bank may be a takeover target. MassMutual, or Massachusetts Mutual Life Insurance Co., may be the pursuer. Could make sense. Jefferies has lots of clients; MassMutual has big bucks. Back in the good old days of 2004 they actually worked together on a corporate lending venture. The two CEOs are buddies. We don't know if that's means fishin', huntin' or bridge. But buddies talk, don't they? Jefferies' stock is clearly on the rise.

WEATHERFORD INTERNATIONAL LTD (NYSE: WFT)

Now that Halliburton Company (HAL) has finished up in Iran, and is done with KBR, word is that they have oil and gas equipment and services provider Weatherford in their sights. That can't be too hard seeing that they have a lot in common and both operate out of Houston. Weatherford's shares have been trading in the high 40s, up some, higher than the lows and lower than the highs of the last many weeks. Not much has happened in the last few days, but maybe it's because those good 'ol boys are deciding whose barbeque place to meet at.

USG CORP. (NYSE: USG)

This one's been around for a while now, and it's worth noting that it's still around, and may be for a while longer. The stock seems poised for a breakout. Is Berkshire Hathaway's Warren Buffett about to make his move? "Yes, hello. I'm calling with a few questions for Mr. Buffett, please...yes, I'll wait..."

It has been an extremely busy week for rumors, with numerous companies' names being floated about. Here's a few of the more notable rumors:

Business Objects S.A. (NASDAQ: BOBJ)

All week long there have been rumors that the global provider of business intelligence software solutions has been the target of a takeover. The company's shares are rallying today as Oracle Corporation (NASDAQ: ORCL) could be making its move. Previously, Oracle has singled out Business Objects as a possible target. What's different this time is that while Business Objects always says they're not interested in selling, they're not saying that now.

USG Corp. (NYSE: USG)

Warren Buffett. Yes, him. If he shows an interest, a company's stock goes up, and USG, the manufacturer and distributor of building materials, which counts U.S. Gypsum as a wholly owned subsidiary, is seeing its stock go up. Will Buffet raise his stake, or just out and out buy the company? Last report was that Buffett's Berkshire Hathaway (NYSE: BRK.A) owns about 19%. of the company. Stay alert.

Foot Locker (NYSE: FL)

For months the global retailer of athletic footwear and apparel has been outdistancing the rumors of a company sale as its shares have continued to slip and fall. Even CEO Matthew Serra made a point of saying that there's nothing to it. But it's hardly news that sales and earnings have been flat for years. Last summer the company hired Evercore Partners as an advisor, and Pathenon Group to look them over. So whatever is up, is certainly can't be very comforting to hear that Nike Inc (NYSE: NKE) is planning to open a series of mall-based specialty stores. Foot Locker is a major reseller of the Nike brand.
