Last week, under the guise of betting on America, Warren Buffett and his Berkshire Hathaway (BRK.A) made an offer to buy all outstanding shares of Burlington Northern (BNI) for a significant premium.

In making the announcement, Buffett confidently claimed that rail would play a big role in the recovery of the economy. What he did not say was that this was a bet on the U.S. dollar.

The clock is ticking away the time before the year ends and I have only begun to sort out the possibilities. In Part 1 of this series, I discussed breaking up my potential picks into three categories: contender, on the fence, and out of the running until the 10 stocks have been identified.

Four contenders have been considered so far: American Eagle Outfitters (AEO), Anadarko Petroleum (APC), Anglo American ADR (AAUKY) and Diageo plc (DEO).

Six more are included in today's review: EZCorp Inc. (EZPW), General Electric Company (GE), Wells Fargo & Company (WFC), Annaly Capital Management ( NLY), Intuitive Surgical Inc (ISRG) plus Berkshire Hathaway (BRK.B). These include the remaining five from 2009 and one more familiar to most investors.

Warren Buffett's (NYSE: BRK.A) decision to buy the 77.4% shares of Burlington Northern Santa Fe (NYSE: BNI) that he did not already own, for $100 each in cash and stock, is like an early holiday present for BNI shareholders.

And first recommended on April 30, 2009 at a price of $67.81, that means BNI shareholders will earn a cool 47% for their April-bought shares. Not bad for a six-month investment. I would say BNI probably was worth 10-15% more, but BNI shareholders will take the immediate pay-off, just the same.

Buffett's move also reflects his stance toward U.S. railroads, a sector I like, too.

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.

Berkshire Hathaway (NYSE: BRK.A) announced the acquisition of Burlington Northern (NYSE: BNI) for $100 per share in cash and stock for a deal worth $34 billion. BRK.A is purchasing the remaining 77.4% of outstanding BNI stock its does not own. BNI November option implied volatility is flat at 36, December is at 35; verses its 26-week average of 37 according to Track Data, suggesting non-directional price fluctuations.

The housing bubble and subsequent "Great Recession" have tarnished the stars of a good many of the world's financial wizards, such as the former heads at Lehman Bros. and Merrill Lynch. But one respected image remains -- perhaps unsurprisingly -- on top: Warren Buffett, chairman and CEO at Berkshire Hathaway Inc. (NYSE: BRK.A).

That's according to a recent quarterly poll of investors, traders, and analysts who subscribe to Bloomberg terminals, those somewhat cryptic news and data computers that are ubiquitous on Wall Street. Buffett, who received favorable nods from 25% of those participating in the poll, walked away with a plurality of the vote, Bloomberg News reported.

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.

As many shoppers have realized in this recession, just because something is cheap doesn't mean it's a bargain.

This is especially true in the stock market, where you definitely get what you pay for.

There have been plenty of low-priced deals on stocks lately, as plenty of good companies watched their shares take a beating in our economic crisis. But that doesn't mean all cheap stocks are worth buying. Unless that bargain goes up in value, it's not a bargain.

So, you think you had a rough year? Check out what happened to Warren Buffett, who is ranked the second-richest man in America despite a drop of $10 billion in his personal wealth during the past year. The culprit for Buffet's loss is the 20% decline in Berkshire Hathaway (NYSE: BRK.A) stock during the past 12 months.

As noted, the Oracle of Omaha maintained his second-place ranking on the list of the richest Americans. The first-place finisher is Bill Gates, who the article notes is "Buffett's friend and bridge partner." What a game of bridge that must be (I am not familiar with the game, but if there is betting involved I don't want to be sitting at that table). Gates maintained his top spot although he lost $7 billion.

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.

He was two years early and now he might be two years late. His facts were right. His timing was off, and I think if you wait for the illustrious NYU professor Nouriel Roubini to give the "all clear sign" you will miss even more of the market upside than you have missed already.

On February 18 of this year I wrote Buffett says buy, then sells, Roubini says wait -- what's an investor to do? -- and it will make interesting reading today. After all it was about three weeks before the market really hit bottom, and I called that, too, posting on March 9: Nostradamus was a punk! Have we reached bottom? -- a lucky call for sure. However, the number of folks thinking the world was coming to an end seemed like the ultimate capitulation.

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.
