Yesterday it was announced very loudly that "my pal Warren" was going to acquire the 77.4% of the Burlington Northern Santa Fe (NYSE: BNI) railroad, that Berkshire Hathaway (BRK.A) does not already own, for $100 per share, offering about a $24 premium to Mondays closing price.

Talk about putting your money where your mouth is -- yikes! Buffett has gone all in, betting the economy is healing, and silencing anyone that questioned his integrity or motives for cautious optimism saying it was all talk!

A major acquisition is coming to light this morning, as Berkshire Hathaway (NYSE: BRK.A, BRK.B) has announced that it is acquiring Burlington Northern Santa Fe (NYSE: BNI). The deal calls for BRK to dish out $100 per share in cash and stock for the 77.4% of BNI shares that BRK doesn't already own. The deal will cost BRK $44 billion.

The acquisition gives us a glimpse into the mind of the Oracle of Omaha, BRK's CEO Warren Buffett. He feels that the "country's future prosperity depends on it having an efficient and well-maintained rail system." Buffett is betting that railroads are going to do well, which would stem from prosperity in the American economy.

No high-priced stock list would be complete without the best known high-priced stock out there -- Warren Buffett's Berkshire Hathaway A Shares (NYSE: BRK.A).

At over $100,000 per share, this is, by far, the most-expensive, most well-known stock on our list. With an investment in Berkshire Hathaway, you are putting your money on the success of one of the greatest investment minds the world has ever known.

Sure, a hundred grand is a lot for one share of stock, but if you want to get your money alongside one of the best track records in modern investment history, that's what you have to pay.

If you are not reading the commentary we receive then you are missing some gems. One of our regulars reminded me of something "my pal Warren" said: "... find companies which can be run by idiots because sooner or later an idiot will be running it."

In Buffett's case he can actually call them up and talk to them. In many cases, he could probably get them to resign. For most of us, all we know is basic things like how's the stock price or has the idiot been indicted?

In early May, I wrote about why I thought Williams Companies Inc. (NYSE: WMB) would outperform four other, more popular stocks. I compared it to Apple Inc. (NASDAQ: AAPL), Google Inc. (NASDAQ: GOOG), Microsoft Corp. (NASDAQ: MSFT) and Berkshire Hathaway Inc. (NYSE: BRK.B).

It was May 11 that I last followed-up on my series of posts, and since then, for about half that period WMB indeed outperformed all four stocks. Since then, however, it has fallen back to second place, behind AAPL.

Another earnings report, another blowout quarter for Intuitive Surgical Inc. (NASDAQ: ISRG), the maker of the da Vinci robotic surgical system. Intuitive Surgical reported last Wednesday and the stock jumped Thursday and Friday on the news while analysts were busy revising their projections for future earnings and upgrading their recommendations and price projections (see: Chasing Value: The amazing Intuitive Surgical).

I have been one of Intuitive's biggest cheerleaders for years and like everyone else was encouraged to find the company still growing successfully on all fronts. Given my favorable opinion of the company, and the stock, I took a look at where it stood after the run-up (closing Friday at $222.53) to see whether there might be any value left, or if the frenetic buying had exhausted the possibility.

Long-term growth stock expert Alexander Green sees long-term upside potential for conservative investors willing to invest along side of Warren Buffett.

Here, the investment director of The Oxford Club reviews Berkshire Hathaway (NYSE: BRK.B), a holding in his model portfolio.

"The market surprised investors with the magnitude of its drop over the last year and a half. Then it surprised them again with a furious rally that began in early March.

"What lies just ahead? No one knows for sure, of course. But we do know several investments that are attractively priced at current levels, such as Berkshire Hathaway (BRK.B), a conservative choice, run by investment great Warren Buffett.

This is a follow-up on the short term results comparing the Williams Companies Inc. (NYSE: WMB) to Apple Inc. (NASDAQ: AAPL), Google Inc. (NASDAQ: GOOG) , Microsoft Corp. (NASDAQ: MSFT), and Berkshire Hathaway Inc. (NYSE: BRK.B).

I wrote a series of stories about why I thought WMB would outperform the other more popular stocks and two weeks is not much of a test unless you have been trading on my suggestions instead of investing.

The final post was Serious Money: Better than Apple, Google, Microsoft & Berkshire Hathaway, Part 5 if anyone cares to go back and review that.

This is the final post on why I believe you would be better off investing in the Williams Companies Inc. (NYSE: WMB) than you would in Apple Inc. (NASDAQ: AAPL), Google Inc. (NASDAQ: GOOG) , Microsoft Corp. (NASDAQ: MSFT), or Berkshire Hathaway Inc. (NYSE: BRK.B).

I hope I made the case this week outlining the deeper value proposition, competitive advantages, reduced risk, and of course the dividend that make Williams the preferable investment for the long term.

This week I have been evaluating the Williams Companies Inc. (NYSE: WMB), a stock that I think would make a good core holding for anyone seeking a dependable dividend, growth potential, and relatively low risk given its current price.

The price was $13.77 when I started the series and $13.00 when I myself bought in.

After the first three posts, I hope the case has been made, but we will continue nevertheless looking at Apple Inc. (NASDAQ: AAPL), Google Inc. (NASDAQ: GOOG) , Microsoft Corp. (NASDAQ: MSFT), and Berkshire Hathaway Inc. (NYSE: BRK.B) for more supporting evidence.

Over the past three years, I have found occasion to recommend these stocks and to pan them when their prices became ridiculous, not always with perfect timing. This week I have been expressing my preference for one over the rest, the Williams Companies Inc. (NYSE: WMB).

Part 3 continues to compare Apple Inc. (NASDAQ: AAPL), Google Inc. (NASDAQ: GOOG) , Microsoft Corp. (NASDAQ: MSFT), and Berkshire Hathaway Inc. (NYSE: BRK.B) to Williams using a variety of common criteria.

In my first post on the subject yesterday, I discussed some of the advantages that Williams Companies Inc. (NYSE: WMB) might have over more popular stock "brands" like Apple Inc. (NASDAQ: AAPL), Google Inc. (NASDAQ: GOOG), Microsoft Corp. (NASDAQ: MSFT) and Berkshire Hathaway Inc. (NYSE: BRK.B) -- all great companies.

I highlighted the yield, book value, and spread between natural gas and oil, concluding that even "my pal Warren" would prefer Williams. Today I continue to look at the various valuation metrics one might contemplate in examining a stock's potential.

Last year most analysts proclaimed that the market would be up by the years end. The only accurate part of the analysis was that the year did end; although not well.

When Burlington Northern Santa Fe (NYSE: BNI) was trading at $114 analysts were silent. When it dropped below $100 and then $90 a share I do not recall anyone writing anything accept that "my pal Warren" was buying. At $80, and then $70 not more than a whisper.

Then yesterday when BNI was trading in the mid $60's (it closed at $64.97) Citigroup (NYSE: C) Investment Research analyst Matthew Troy cut shares of Burlington Northern Santa Fe Corp. and Canadian Pacific Railway Ltd. to "Sell" from "Hold."

If I write about Apple Inc. (NASDAQ: AAPL), Google Inc. (NASDAQ: GOOG), Microsoft Corp. (NASDAQ: MSFT) or even one of my favorites Berkshire Hathaway Inc. (NYSE: BRK.B). I know that readership will be higher than if I write about less popular names.

Most recently this happened when I wrote about Williams Companies Inc. (NYSE: WMB) and to my disappointment interest was not high. Maybe it was the header: Chasing Value: Williams has the pipes and it's not blowing smoke -- go back and read it.

"Though the past year has been tough for Warren Buffett, we still like Berkshire Hathaway (NYSE: BRK.B), which we believe is well-positioned for the year ahead," says Paul Tracy.

In his StreetAuthority Market Advisor, he looks at the holding company which is a position in his "undervalued gems" model portfolio. Here's his review.

"For only the second time in the investment-based company's 44 years, Buffett saw the book value of Berkshire drop. Of course his book value decline of 9.6% should be put in context with the 37% loss incurred by the S&P 500.
