It's been a busy week in the equities market. Earnings reports are coming fast and furious. I thought I would catch up on a few companies with a brief look at their numbers.

First up is an entity from the consumer products sector. Kimberly-Clark (KMB), a colleague of Procter & Gamble (PG), issued fourth-quarter data on Friday. Sales increased over 8%, with a better currency environment helping things out. Organic sales powered up almost 3%, driven in part by higher prices. Per-share profit went up over 15% to $1.17.

All three of the major indexes finished Tuesday in the red, but there were several big names that moved up to new 52-week highs in Tuesday's trading.

Walgreen Co. (NYSE: WAG): The drugstore giant had a really good day on Wall Street after posting better than expected earnings in the morning before the market opened. The company posted earnings of 44 cents per share versus analyst estimates of 39 cents. The stock set a new 52-week high of $38.44 and closed the day up 9.2% at $37.35.

TheStreet.com's Jim Cramer says managers are being judged on their exposure to this rally.

Did Abbott Laboratories (NYSE: ABT) (Cramer's Take) scare the shorts? Or was it so easy to get people to buy winners and sell losers at the end of the quarter that the market had to go higher? What makes a thin market levitate rather than decline?

I got to thinking about this and the incredibly bullish comments by one of my favorite strategists, Byron Wien -- comments that are even more bullish than usual for him -- and concluded that the single best thing that the bulls have going for them is that the market is up big and you look like a real knucklehead if you aren't invested or haven't made any money on the long side going into the fourth quarter.

Traders had on their rally caps today, and the DJIA moved as high as 9,823 as it renewed its ascent toward 10,000. The index moved back down a bit at the end of the day as traders got lazy during a session in which most of the news came before the bell.

Abbott Laboratories (NYSE: ABT) and Xerox Corporation (NYSE: XRX) both announced deals today that pumped some air into the M&A business. Financial shares are mostly moving higher because increased M&A activity generally means more fees for financial services companies. Trading volume was light, mostly due to the Yom Kippur holiday today.

Today's numbers:

Dow 9,789.44 +124.25 (1.29%)
S&P 500 1,062.88 +18.50 (1.77%)
Nasdaq 2,130.74 +39.82 (1.90%)

With the market being propelled upward due to private equity and corporate acquisitions, investors should not stay on the sidelines. Rather, they should target private equity's next frontier -- IT services. Of the companies in this sector, Unisys Corp. (NYSE: UIS), Perot Systems Corp. (NYSE: PER) and Ingram Micro, Inc. (NYSE: IM) may be worth examining.

A few months ago, I suggested several sectors and companies that private equity could target next. On Friday, TheStreet.com reiterated one of those sectors -- IT services. Here's how much seven such companies have gone up or down since my March 29th post along with their market capitalizations ranked by their Price/Earnings to Earnings Growth (PEG) ratios:

Back in 1988, Darwin Deason founded Affiliated Computer Services, Inc. (NYSE: ACS) to help build computer and software systems for major clients. It's turned out to be a successful business as the company generated $5.3 billion revenues last year. A big focus is on processing bank transactions and healthcare claims.

Now, Deason is taking ACS private in a $8.2 billion deal. The private equity buyer is Cerberus Capital Management.

Like many techs, ACS suffered from a stock options investigation. It was a managerial distraction (the CEO departed) and expensive.

So it's understandable why Deason wants to leave the public markets.

What's more, Deason will roll-over his major position in ACS stock in the deal. He certainly sees long-term potential here. And with voting control, he can basically call the shots.

However, he may have to bump the $59.25 offer up a bit. The current stock price is $60.10.
