I've recently taken a quick look at Teradata Corp. (NYSE: TDC). Teradata was a well-received spin-off of NCR Corp. (NYSE: NCR). Teradata is a commercial data warehousing, processing, and analyzing specialist for major business enterprises. The company focuses on the development of retail market intelligence based on consumer habits and trending, among other analytical data specialties.

It was recently announced by Teradata that a 550 store, an Italian supermarket chain, is expanding its Teradata system. Streetinvesting.com reported that the Italian firm wishes to more fully utilize its Teradata based information management systems across a broader range of its operations. Streetinvesting.com stated, "Teradata CRM provides a detailed understanding of customer purchase behaviors and preferences, and enables personalized offers to customers. Teradata's scalability supports growing businesses with increasingly complex business demands driven by robust growth requirements and the need for pervasive business intelligence."

In my opinion, Teradata has been performing adequately as a company, reporting $200 million net income for 2007 on sales of $1.7 billion. Currently, the company's share performance is lagging noticeably within its peer group, even though its income statement is showing four consecutive years of gross income increases. Operating expenses do appear to be weighing heavily on the company's performance, and taxes are certainly an issue.

At the time of this research, Teradata's shares are trading very near their 52-week low, prepared to open Monday at $21.77 against a 52-week high of $30.08. Analyst sentiment appears to be confident but reserved in regard to this stock. The consensus is calling it a buy.

Jim Cramer's second CEO in his "Transformational CEOs" list is Mark Hurd of Hewlett-Packard Co. (NYSE: HPQ). He said you can slap a buy on him because he took over H-P in March of 2005 after Carly Fiorina. H-P shares have doubled and he took it out of disarray. It was even behind Dell Inc. (NASDAQ:DELL) in market share. The payrolls were bloated and the server business was a joke. Hurd went back to focus on engineering and the company even delivered on Cramer's prediction of an earnings upside surprise. Hurd even took NCR Corp. (NYSE: NCR) up some 300% before joining H-P.

Last night, Cramer noted Schering-Plough's Fred Hassan as one of his top five transformational CEOs.

The call on H-P and Mark Hurd is hard to argue with. Dell still may have more of a leveraged upside if the company can swing it around and live up to the expectations, but so far it is hard to argue with this call.

MOST NOTEWORTHY: Celgene Corp (CELG), Luminent Mortgage Capital (LUM) and CNET Networks, Inc (CNET) were some of today's notable initiations:

• Bernstein started Celgene Corp (NASDAQ: CELG) with an Outperform rating and $62 target. The firm believes Revlimid can achieve the company's global sales of more than $3.2B by 2012 and feels the recent low $50's is an excellent share entry point.

• JP Morgan initiated Luminent Mortgage Capital (NYSE: LUM) with an Overweight rating based on valuation.

• First Albany initiated CNET Networks inc (NASDAQ: CNET) with a Buy rating and $10 target, citing valuation.

This week, NCR Corp (NYSE:NCR) announced that it will spin-off its Teradata division, which is a top player in data warehousing. NCR, on the other hand, will focus on its self-service business, such as ATMs, kiosks and so on.

The deal should take six to nine months to complete. However, according to a report from The Daily Deal [a paid service], Teradata may not even hit the public markets. That is, it could be bought-out.

By private equity firms? Well, given Teradata's cash flows – and long-term contracts – it would be attractive to a financial buyer. But, the company would also make a great fit for major tech companies, such as Oracle (Nasdaq: ORCL), IBM (NYSE: IBM) and even Hewlett-Packard (NYSE: HPQ). All of these companies have been quite acquisitive.

Valuation for Teradata is tough to determine – with a range of $2 billion to $4.5 billion. Although, given the future growth prospects for the company, it's a good bet that the valuation is at the top end.
