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!

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.

Rail carloadings for agriculture and coal are down, as is containerized trade traffic, and the near-term does not look bright, but you'd never know it from Burlington Northern Santa Fe's stock price trend.

Institutional investors have bid-up shares in anticipation of U.S./global recoveries. Therefore, I'm reiterating my Buy rating for Burlington Northern (NYSE: BNI), first recommended on April 30, 2009 at a price of $67.81. However, there is caveat: wait for a pull-back to about $75, and hope the market gives you the chance at a decent entry point.

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.

I think it's fair to say that there's much trepidation about the earnings season that picks up steam this week. And for better or worse, numbers from the big financials have begun to roll in. Last week we saw profit sink for JPMorgan Chase (NYSE: JPM) and significant losses from Bank of American Corp. (NYSE: BAC), Citigroup Inc. (NYSE: C), and Deutsche Bank (NYSE: DB).

Analysts surveyed by Thomson Reuters expect Bank of New York Mellon Corp. (NYSE: BK) to be among those financials reporting fourth-quarter earnings growth this week. They anticipate that Bank of New York will post a profit of $0.70 per share, compared to $0.67 per share a year ago and $0.72 in the previous quarter. Revenue is expected come to $3.8 billion, about the same as it was a year ago. Bank of New York has fallen short of earnings estimates in two of the past five quarters, by as much as 11.1%. For the full year, analysts are looking for $2.78 per share (+5.8%) on $14.8 billion (+4.2%). The consensus recommendation of analysts is to buy BK, and the long-term EPS growth rate forecast is 10.7%. Shares are 48.7% lower than a year ago. Other financials expected to report quarterly earnings growth this week include SunTrust Banks Inc. (NYSE: STI) and M&T Bank Corp. (NYSE: MTB).

"It's hard to find any good news these days but I was pleasantly surprised with the third-quarter railway results, as almost all of the 'class 1 carriers' reported better than expected earnings," notes analyst Tom Slee.

The contributing editor to Gordon Pape's Internet Wealth Builder explains, "Several rail stocks are starting to look attractive at these depressed levels and Burlington Northern (NYSE: BNI) remains my preferred choice in the group." Here's his outlook.

"Even with the economic downturn starting to bite, reduced fuel costs and increased freight rates offset lower volumes. Equally important, the companies remain cautiously optimistic despite the miserable outlook.

"They are confident that further freight rate price increases in the 4% to 5% range are sustainable and will still allow them to undercut inefficient truckers.

"Unfortunately, none of this prevented the stocks from being battered during the market collapse. However, I think that fourth-quarter profits are likely to remain strong and the longer term outlook for railroads remains favorable.

"Burlington Northern continues to power ahead. A shrinking economy must eventually take its toll but there was no sign of any weakness in BNI's third-quarter results. Operating earnings came in at $1.91 a share, up 29% from $1.48 in 2007.

Today was a busy economic day with data, but the selling in Asia as a "sell the news" reaction from the first Japan rate cut in seven years should have ruled the roost. Employment costs came in at 0.7% as expected, and personal income and spending showed no surprises. The markets also ignored a weak Chicago purchasing managers reading. This was a horrible month, but the DJIA ended up roughly 1,000 points higher from the close last Friday.

Below are today's unofficial closing bell levels:

Dow 9,325.01 +144.32 (1.57%)
S&P 500 968.75 +14.66 (1.54%)

Burlington Northern Santa Fe Corp. (NYSE: BNI) was after an SEC Filing noted that Warren Buffett's Berkshire Hathaway bought an additional 825,000 shares of common stock and now holds a beneficial ownership of 64,610,418 shares of common stock. Shares were up 2.7% at $88.93 right before the close today.

DivX Inc. (NASDAQ: DIVX) traded higher by over 6% after the online media player company beat its earnings expectations. The company also raised its fiscal non-GAAP earnings range to $0.58 to $0.60 from a prior range of $0.52 to $0.58, but lowered its revenue guidance because of product expansion and slower spending. Shares were up over 25% at $6.99 right before the close.

"Warren Buffett's holding company, Berkshire Hathaway (NYSE: BRK.B), has been the single greatest investment of our lifetimes," says Alexander Green, noting, "His compounded annual gain from 1966 to 2007 was 21.1% vs. 10.3% or the S&P 500."

In the Oxford Insight, the investment director explains, "It is now time to buy the 'ultimate no-brainer'." Here's his assessment.

"Despite this strong long-term performance, Buffett experienced a rare earnings letdown during the second quarter of this year.

"Although revenue increased 10% to $29.3 billion, insurance related write-downs hurt the company's bottom line. Still, the shortfall was far from cataclysmic. For the quarter, earnings fell 7.6% to $2.88 billion.

"Despite the shortfall, the company still maintains a top-notch credit rating and has over $28 billion in cash, a war chest for the world's greatest investor. How has Buffett been so successful? He takes a disciplined value approach to investing. And he sticks with it.

Through May, the S&P 500 is down 5%. The interesting news to me is that some stocks have been doing phenomenally well. They appear to be benefiting from the weak dollar and strong demand for raw materials -- like oil and coal -- in emerging markets.

It happens that I picked three of them for my newsletter -- whose average stock has risen 26% since the beginning of 2008. Here are the top three -- and how much they've risen since their first mention there:

• Walter Industries (NYSE: WLT) +124%. Walter is a coal, natural gas, and home construction and finance company that is spinning off the latter and is benefiting from rising coal prices.
• Southwestern Energy (NYSE: SWN) +36%. Southwest is an oil and gas explorer that was just added to the S&P 500.
• Burlington Northern (NYSE: BNI) +24%. Burlington runs trains and Warren Buffett owns its stock. One analyst boosted 2008 EPS estimates from $5.90 to $6.05 due to fuel surcharges and rate increases, partially offset by significantly higher unhedged fuel costs and flat-to-modestly-lower volumes.

"Having spent a lot of time recently studying the North American transportation industry, my conclusion is that trucking is on the decline while the railroads are poised to increase market share," notes Tom Slee.

The contributing editor to Gordon Pape's Internet Wealth Builder states, "The logical conclusion: buy rail stocks now." Here he looks at Kansas City Southern (NYSE: KSU) and Burlington Northern Santa Fe (NYSE: BNI).

"Who would have thought it? Railways are having a good year. They were supposed to be hunkered down, riding out the recession. Instead, the old iron horse is thriving.

"Surging demand for commodities is more than offsetting a slump in building materials shipments. Even higher energy costs are proving a plus for the railroads. Each jump in oil prices gives them a bigger edge over their gas guzzling competitors: trucks.

"Most important, the rails are able to raise rates despite the economic downturn. Their surcharges are sticking. Yet the stocks are out of favour.

When a major, metropolitan U.S. newspaper discovers a investment trend or a hot sector, count on increased share demand for companies in the sector. When that paper is one of the top three dailies, in this case The Washington Post, count on even more demand.

On Monday, The Washington Post examined the resurgence of the United States' railroad sector, touching on many of the themes discussed here during the past six months, and described why the rails' services are likely to be in demand for many years.

For nearly 30 years, the rails, long neglected in the United States, were considered passé. Then the globalization era dawned, with its exports and demand for commodities. Add a price of oil that's basically risen for 10 years and the results is: the rails are back. And with the above in mind, Burlington Northern (NYSE: BNI) is worth an evaluation.

With 32,000 miles of track in the western U.S. and two Canadian provinces, Burlington Northern accounts for about 45% of the west's traffic and about 23% of U.S. rail traffic.

Analysts see 2008 revenue growth of about 6-8%, down from double-digit growth a year earlier, but still healthy. Margins should remain solid, with modest pricing power. The Reuters F2008/F2009 EPS consensus estimates for BNI are $5.92/$6.81.

Even better: like the three other major U.S. railroads, BNI is in a relative sweet spot until the United States determines its energy policy for the 21st century. Or should one say 'if the United States determines its energy policy for the 21st century.' Investors will carefully note that the value Wall Street attaches to rail stocks pretty much mirrors the price of oil's ascent, due to the higher truck transportation costs implied by a higher price of oil.

Among the companies reporting on Tuesday were JetBlue Airways Corp. (NASDAQ: JBLU) and Burlington Northern Santa Fe Corp. (NYSE: BNI).

JetBlue reported a narrower-than-expected loss in the fourth quarter, and its first full-year profit in three years. It also announced that it's negotiating a deal with investor Deutsche Lufthansa AG.

JetBlue lost $4 million, or 2 cents a share, in the quarter ending December 31. It posted a profit of $17 million, or 10 cents a share, in the same quarter of 2006. An increase in traffic and operational improvements helped offset rising fuel costs. Revenue rose 16.6% to $739 million. Analysts surveyed by Thomson Financial had expected a loss of 5 cents a share on revenue of $731 million.

For the full year, JetBlue earned $18 million, or 10 cents a share, versus a loss of $1 million, break-even on a per-share basis, in 2006. Revenue jumped 20.2 percent to $2.84 billion. Wall Street had expected a 2007 profit of 7 cents per share on revenue of $2.83 billion.

Shares surged 20.24%, or $1.00, to close at $5.94. Shares had fallen to a 52-week low of $4.30 last week.
