To continue to grow, many companies have little choice but to spend large amounts on acquisitions. But at a certain point, the operations get too complicated and bloated. The solution? Yes, it's to unwind the deals. Often, Wall Street will be enthusiastic. Just look at Wednesday's announcement from conglomerate ITT (ITT). On news of its plan to split into three publicly traded companies, the shares spiked 16%.

In fact, this may actually be the start of a key trend for 2011. After all, early Thursday Marathon Oil (MRO) announced that it will spin-off its refining and sales operations as a public company (the deal should be closed on June 30). In early trading, the company's shares were up about 10%.

ITT Corporation (ITT) announced a plan for a tax-free spin-off to shareholders of its water-related businesses and Defense & Information Solutions segment. ITT will continue to trade on the New York Stock Exchange as an industrial company that supplies highly engineered solutions in the aerospace, transportation, energy and industrial markets. Overall option implied volatility of 23 is below its 26-week average of 26, according to Track Data, suggesting decreasing price movement.

NASDAQ 100 (QQQQ) overall implied volatility at 20; 26-week average is 22.

Options Update is by Stock Specialist Paul Foster of theflyonthewall.com.

On CNBC this week, hedge fund manager Steve Eisman gave his first TV interview in ten years. Yes, he was the star in Michael Lewis' "Big Short," in which he made a bundle by shorting subprime securities.

Now Eisman has found another trade: for-profit education companies. In fact, his latest report is called "Subprime Goes to College."

Option traders appear to be setting up for a bullish move on ProLogis (PLD). Traders plowed into 1,067 new call option contracts -- 2.81 times the average volume -- on the stock on Thursday. And we know that traders were eager to get into this trade because 95% of the trades came in on the ask price.

ProLogis looks like it formed a bottom in early July and has since formed a higher low in August. The stock closed Thursday at $10.92, down 0.18% during the past month.

Below, we ask 'Is this a Buffett type company?', 'Should I buy at this price?' and also look at some of the specific criteria in which ITT passes the Buffett model."

Today was another trading day bare of major economic data. Shares were all over the place today with the indexes not giving any clear direction at any point of the day. It was not until right before the close that you had a real feel for whether we would close up or down today.

Here are the unofficial closing bell levels:

Dow 9,874.31 -11.49 (-0.12%)
S&P 500 1,073.56 -2.63 (-0.24%)

If you've been watching earnings this past week, or if you read last week's Week in Preview, then this coming week may leave you feeling a bit like Bill Murray in Groundhog's Day. That is, again analysts surveyed by Thomson Reuters expect earnings declines to be more frequent and deeper than earnings gains.

Motorola Inc. (NYSE: MOT), Dow Chemical Co. (NYSE: DOW), Anadarko Petroleum Corp. (NYSE: APC), IAC Interactivecorp (NASDAQ: IACI), Moody's Corp. (NYSE: MCO), Elizabeth Arden Inc. (NASDAQ: RDEN), Devon Energy Corp. (NYSE: DVN), Diebold Inc. (NYSE: DBD), Tyco International Ltd. (NYSE: TYC), United Parcel Service (NYSE: UPS), Cisco Systems Inc. (NASDAQ: CSCO), Polo Ralph Lauren Corp. (NYSE: RL), ITT Corp. (NYSE: ITT), and Walt Disney Co. (NYSE: DIS) are scheduled to report quarterly results this week, and they're all expected to report double-digit declines in earnings.

But again this week, let's take a look who Wall Street feels may have done well in the past quarter.

TheStreet.com's Jim Cramer says the economics are still dire, but stocks aren't even flinching on huge warnings.

Preannouncement after preannouncement after preannouncement. Yawn after yawn after yawn.

I've never seen anything like it. Worst ever. But, did anyone really think Ingersoll Rand (NYSE: IR) (Cramer's Take), cut in half here, would make the quarter? How about Nucor (NYSE: NUE) (Cramer's Take)? Stanley Works (NYSE: SWK) (Cramer's Take)? ITT (NYSE: ITT) (Cramer's Take)? Eaton (NYSE: ETN) (Cramer's Take)? Pentair (NYSE: PNR) (Cramer's Take)? I figured they would all miss. I bet the ones that preannounced last night hardly go down. Why should they? ITT's up nicely. Eaton's unchanged. Not even glancing blows. Nucor's up 10! Ten from a preannouncement.

Most glaring: the 10% miss by Joy Global (NASDAQ: JOYG) (Cramer's Take) with the almost 15% rally! Now that's gigantic.

That's why people feel better about this tape. In the end of that big run up, stocks failed to react to even the biggest beats. Now they fail to react to the biggest misses.

Here are some highlights from this past week's earnings coverage from BloggingStocks:

• Bear Stearns Cos. Inc. (NYSE: BSC) reported a profit that missed expectations by a penny.
• Caterpillar Inc. (NYSE: CAT) posted higher profits in the first quarter, boosted by global gains.
• Charles Schwab Corp. (NASDAQ: SCHW) first-quarter earnings were in line with expectations.
