Ten weeks into the year and never a dull moment. Pondering the remaining 42 weeks and beyond, where will value be found? We know that "my pal Warren" is on the prowl waist high in Berkshire Hathaway cash to invest, and he is on record as chomping on the bit to do so. Just this morning it was reported that Buffett had closed a $9 billion deal to buy Lubrizol Corp. (LZ), the Wickliffe, Ohio-based maker of engine lubricants.

More evidence of this abounds: Wednesday March 2, (Reuters) - US-based Berkshire Hathaway aims to enter the Indian insurance sector as a corporate agent of Bajaj Allianz General Insurance.

"So far this year, 36 U.S.-traded stocks have declared stock splits, nearly triple the amount from all of last year," says Richard Moroney.

The editor of Dow Theory Forecasts -- an advisorty service that has focused on blue chip stocks for over 50 years -- explains, "We have reviewed stocks that have climbed to within 25% of the price of their last split. Below, we review four of these stocks, all potential stock-split candidates: Apple (AAPL), Lubrizol (LZ), TJX (TJX) and Varian Medical Systems (VAR).
