SAN DIEGO (ETFguide.com) - Warren Buffett is finally spending some of Berkshire Hathaway's cash hoard. And he's buying a railroad company. As the greatest investor of our generation, does his latest acquisition signal a market bottom?

Dissecting the Deal

Buffett's firm, Berkshire Hathaway (NYSE: BRK-A), agreed to buy Burlington Northern Santa Fe Corp. (NYSE: BNI) for $100 a share valuing the deal at $44 billion.

Many investors think of stocks and the stock market in general as nothing more than little pieces of paper being traded back and forth among investors, which might help prevent investors from becoming too emotional over a given position but it doesn't necessarily allow them to make the best possible investment decisions.

That's why Buffett has stated he believes stockholders should think of themselves as "part owners" of the business in which they are investing. By thinking that way, both Hagstrom and Buffett argue that investors will tend to avoid making off-the-cuff investment decisions, and become more focused on the longer term.
