Not even Warren Buffett was immune to the stock market’s rampant first-half gyrations, as Berkshire Hathaway Inc. notched its worst first half in 18 years, with the shares skidding more than 16%. But only a fool would count out the great Oracle of Omaha, who has spent the past several months restructuring his company’s portfolio and is now ready to come out swinging for the year’s second half.

As Money Morning’s Horacio Marquez noted in his most recent “Buy, Sell, or Hold” feature, Berkshire Hathaway has had a tough start for the year.

The company’s net earnings for the first half were $3.8 billion – a 33% decline from the $5.7 billion reported for the same period last year. But even though the second quarter was weak – especially by Buffett’s standards – it showed marked improvement from the first three months of the year.

Berkshire reported about $1.6 billion in unrealized losses from derivatives in the first quarter. But after warning that derivatives contracts will often “swing wildly,” the company posted $689 million in derivatives gains in the second quarter.

Berkshire’s revenue actually rose 10% to $30.09 billion for the quarter.

But that’s not enough for Buffett, who has set about restructuring his company’s holdings. In the past few months, Berkshire has reduced its investments in Anheuser Busch Cos. (NYSE:BUD) and Trane Inc., and added positions in NRG Energy Inc. (NYSE:NRG), Ingersoll-Rand Co. Ltd (NYSE:IR), and Sanofi-Aventis (ADR:SNY).

According to filings with the U.S. Securities Exchange Commission (SEC), Berkshire in June reduced its stake in Anheuser Busch to 13.85 million shares, less than half the 35.56 million shares it held as of March 31. It’s likely the company received a tidy sum for its shares, as earlier that month InBev SA (PINK: INBVF) offered $65 a share for the American icon. Buffett admits to bailing on the Bud brand before InBev raised its offer to $70 a share, but AB was trading at close to $62 a share on June 30, much higher than the $47 a share the company was valued at in late March.

Also in March, Berkshire dumped its 10.9 million shares of Trane Inc. That stake was valued at more than $500 million as of March 31.

After unloading in the spring, Buffett treated Berkshire Hathaway to a $4-billion shopping spree over the next several months. By the end of the second quarter, Berkshire’s stake in French drug maker Sanofi Aventis had shot up 317,200 shares to reach 3.9 million. Berkshire also added 5 million shares of Ingersoll-Rand, and announced new holdings in NRG Energy, the second-biggest power producer in Texas. Berkshire had 3.24 million NRG shares as of June 30.

Even more interesting, in a move that highlighted Buffett’s bullishness on railroad stocks, Berkshire doubled its stake in Union Pacific Corp. (NYSE:UNP), taking its holdings from 4.45 million shares at the end of March to 8.91 million shares as of June 30.

Last year, Buffett and Berkshire road the rails hard. Buffett made his first move on Burlington Northern Santa Fe Corp. (NYSE:BNI) last April, acquiring nearly 40 million shares – or close to 11% – of the railroad. He then moved on to snap up 10.5 million shares of Union Pacific Corp., and 6.4 million shares of Norfolk Southern Corp. (NYSE:NSC).

Later in August, Berkshire went shopping again, loading on an additional 3.3 million shares of Burlington and another 6,000 in September. But Buffett didn’t stop there: He added yet another 10,300 shares of Burlington over the two-week period ending Jan. 22, bringing Berkshire’s total stake in the company to 18.2%.

Berkshire’s second-quarter acquisitions, which were disclosed in an SEC filing last week, are only a fraction of the $3.98 billion Berkshire spent on stocks in the April-June period.

Even if Buffett bought the shares at their highest second-quarter prices, which he almost certainly did not, the total cost would only have been about $260 million. That means more than $3.5 billion went into smaller amounts of unnamed stocks the company was not required to disclose.

Where that money went is anybody’s guess, but Buffett indicated in a recent interview with CNBC that a portion of it went into one of two stocks: Wells Fargo & Co. (NYSE:WFC) or American Express Co. (NYSE:AXP).

Wells Fargo stock has plummeted 22% in the past year, while American Express is down more than 37% in that time. However there may be some clues as to which stock Buffett really believes will rebound in some earlier comments he made.

“We’ll say at American Express… they are experiencing credit deterioration and they’re experiencing it sort of in all segments,” Buffett said earlier on CNBC’s Squawk Box. “So they’re seeing the rich customers slow down in payments, slow down in purchases.

“And American Express can describe that rather than I,” he added, “but I pay a lot of attention to that sort of thing. And incidentally, it will get cured at some time in the future, but right now the situation is getting worse and I would say that I don’t see any early end to that.”

That assessment doesn’t seem particularly favorable, particularly compared with comments Buffett made with regards to Wells Fargo just a few months ago.

“Wells Fargo stock was down last year,” Buffett said, “I don’t think the intrinsic business value shrunk. In fact, I said I thought it probably increased a touch.”

Berkshire already owns considerable stakes in both companies.

According to a report in The Daily Telegraph, “Speaking on a BBC documentary, Mr Soros said that at the heart of the financial crisis was the culmination of a 60-year-old boom in leverage, the result of which will be a far deeper downturn than many expect.”

Soros predicts the both the financial industry and the indebtedness of the US consumer will have to shrink, causing a “very painful adjustment”.

“Americans used their economic freedom to ruin themselves,” says Bill Bonner.

“Shareholders consented to hundreds of millions in bonuses and stock options for key executives. Investors signed up for hedge funds, willingly giving managers ‘2% and 20%’ for putting quarters in the slot machine for them. Taxpayers allowed huge tax cuts – widely believed to be aiding the wealthy – because they looked forward to the day when they would be wealthy too. And almost everyone, everywhere eagerly went on a spending spree, in the belief that this new, kindler, gentler capitalism would add wealth faster than they could get rid of it. And if they overspent, hyper-capitalism would soon catch up.”
