Analyst initiations:

"Dividend growth has become increasingly scarce on Wall Street," says says Chuck Carlson, an expert on dividend reinvestment plans. In his The DRIP Investor he looks at two stocks boosting their payouts.

"For the first time in five years, the number of companies in 2007 boosting their dividends declined nearly
6% from the previous year, according to Standard & Poor's. And the slowdown in dividend growth continued in the first quarter of 2008.

"The first quarter marked the seventh consecutive three-month period of year-over-year declines in the number of companies raising dividends. Through the first three months of this year, 19% fewer companies raised dividends than in the year-earlier quarter.

"Even more alarming, 83 companies decreased their dividends during the fi rst quarter, according to S&P. That's up from just 19 in the same period in 2007 and is the highest number of dividend decreases since 1991.

"Nevertheless, there are still plenty of companies willing to boost their dividends, and you can now buy such companies at bargain prices.

Readers of this space know that the investment bias is toward large-cap companies with demonstrated business models and who have a competitive advantage in established markets, preferably with a favorable global trend as a support. And with the above in mind, Emerson Electric is worth a review.

Emerson Electric Co. (NYSE: EMR) is an industrial conglomerate that operates more than 60 diverse businesses in five business segments: process management, industrial automation, network power, climate technologies, and appliance/tools.

In general, analysts expect Emerson's FY 2008 revenue to increase 10-12% on solid performances from its network power and process management segments.

When Warren Buffett announced he wanted to use between $40 and $60 billion to buy a company several days ago, picking a target for the billionairest of all billionaires became the favorite pastime of financial writers everywhere -- and our bloggers were as eager as anyone else to come up with just the thing for the guy who already has everything (and everything, in this case, includes bunches of shares of companies as diverse as dull sheetrock manufacturer USG Corp. (NYSE: USG) to hip shoe company Nike Inc. (NYSE: NKE)).

Of course, Buffett's needs are unique. First of all, the company has to be both big and a good value -- no 80x P/E multiples for Warren. It has to be a relatively simple business (I'm thinking nanotech is out), have a good management team and no dark and dirty secrets (so sub-prime lenders are probably off the list). Finally, the company should have solid, long-term competitive advantages.

Sheldon Liber suggests a couple that might make the grade: Allstate Corp. (NYSE: ALL), the insurance company, which at about $38 billion in market capitalization and a 7.8x P/E ratio fits both the "big" and "cheap" qualifiers. Plus, we all know that Warren Buffett loves insurance companies, and given its retail approach, it's not much of a competitor with longterm portfolio company GEICO. Emerson Electric (NYSE: EMR) also seems a good candidate with its $37 billion market cap and 19x P/E ratio -- but is it simple enough? Its business is, according to Hoover's, making "a host of electrical, electromechanical, and electronic products, many of which are used to control gases, liquids, and electricity." Hmmm.

When Gary Sattler suggests Warren might buy General Electric Co. (NYSE: GE)'s plastics division, it's a good concept (simple, well-managed) but the price is way too low at around $10-12 billion. A commenter, however, brings up a good replacement in Lowe's Companies Inc. (NYSE: LOW); it has a $47 billion market cap and a reasonable P/E ratio of 15.5x. What's more, it has none of the bad-management baggage of competitor Home Depot Inc. (NYSE: HD). Does it have a "moat," though? I suppose that's a question for Warren. He does own some of each company, meaning that he's already emotionally invested in the sector (a plus) although it's obvious from our near-tie in the Battle of the Brands that neither holds a substantial consumer-facing edge competitively.
