As always, there is a volume of speculation after the much anticipated release of the quarterly changes in holdings report from Berkshire Hathaway (BRK.A). While leaving all the deep analytical number crunching for greater minds than my own, I'd like to take a look at what Warren Buffett could be telling us through his company's latest form 13F.

Why has Warren Buffett swallowed Burlington Northern Santa Fe (BNI) while letting go of Norfolk Southern (NSC) and Union Pacific (UNP)? Being the master of due diligence, Mr. Buffett has most likely determined that BNI is the most attractive of the three. The future of rail transport is all but guaranteed to shine, and I believe that Mr. Buffett has exited the other two rail companies simply to avoid conflict of interest issues.

Now here's an eye opener. Warren Buffet's Berkshire Hathaway (BRK.A) has decided to split its shares 50 for 1. This would drop the price of the company's cheapest stock down from about $3,247.00 per share to $65. The class A shares, never split, still trade at about $97,500.

Analyst Upgrades

• Kaufman Bros. upgraded Yahoo! (YHOO) to buy from hold after channel checks indicated display advertising is seeing continued improvement in pricing and demand. The firm finds the risk/reward profile on Yahoo! shares attractive at current levels and raised its price target on the stock to $20 from $19.
• Citigroup upgraded Edwards Lifesciences (EW) to buy from hold following the company's investor meeting as it believes new product launches will serve as catalysts in 2010. Citi raised its target on shares to $101 from $72.
• Deutsche Bank upgraded BWAY Holding (BWY) to buy from hold following the company's Q4 results and raised its target on shares to $22 from $17.

• Nokia (NOK) was raised to hold from sell at Societe Generale.
• NCR Corp. (NCR) was upgraded at JPMorgan to overweight from neutral.

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.

Analyst upgrades:

• Goldman upgraded Aeropostale (ARO) to neutral from sell. The firm, which has a $34 target on the stock, cites the recent sell-off in shares for the upgrade.
• Janney Montgomery upgraded Consolidated Water (CWCO) to buy from neutral on valuation and on expectations the company's earnings will recover in 2010. The firm has a $15 target on the stock.
• Wunderlich upgraded Transmontaigne Partners (TLP) to buy from hold on valuation as it believes the sell-off on the company's Q3 results is overdone. The firm keeps a $26.50 price target on the stock.
• Mobile TeleSystems (MBT) was upgraded to buy from neutral at UBS.
• HSBC (HBC) was raised to buy from hold at Societe Generale.
• Redwood Trust (RWT) was upgraded to outperform from market perform at JMP Securities.

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.

CSX (NYSE: CSX), a railway entity similar to companies such as Burlington Northern Santa Fe Corp. (NYSE: BNI), Norfolk Southern Corp. (NYSE: NSC), and Union Pacific Corp. (NYSE: UNP), saw a nice bid during Tuesday's after-hours session. The market enjoyed CSX's Q3 earnings report so much it sent shares of the company higher by 2.6%.

What was so good about the data? According to TheStreet.com, CSX made 74 cents per share from continuing operations. The analyst community was counting on 71 cents per share. Perhaps more importantly, management seemed pretty upbeat on the state of the economy. Like a lot of other pundits, CEO Michael Ward thinks that the recession will eventually start to wane, and that we may have already experienced the bottom of the cycle.

CSX (NYSE: CSX), a railway company whose peers include Burlington Northern Santa Fe (NYSE: BNI), Union Pacific Corp. (NYSE: UNP) and Norfolk Southern Corp. (NYSE: NSC), reported earnings for the second quarter on Monday after the bell. Net sales declined 25%, and earnings from continuing operations declined 24% to 72 cents per share.

Declines are never nice, but for a company like CSX, it's only to be expected. The recession continues to have an impact on operations. Management said that volumes decreased; it also mentioned how CSX is doing its best to run as efficiently as possible to combat the dropping top line. Maybe it's working out, because according to Reuters, the company beat Wall Street estimates by 10 cents.

In running a very tight stock screen recently for value plays Burlington Northern Santa Fe (NYSE: BNI) showed up on a list of 14 stocks. Interestingly all the large railroad stocks did. This reminded me of several stories I have done on the subject, the most recent being Chasing Value: Watch BNI -- the heck with Citigroup.

To summarize, about six weeks ago a Citigroup (NYSE: C) analyst declared it was time to sell the stock when BNI was trading in the mid $60s -- I said investors should do the opposite, it was a great value. Friday the stock closed at $76.98. Even at this price it is a value and ever more so with oil prices steadly creeping up.
