BILLIONAIRE Warren Buffett?s Berkshire Hathaway Inc. slumped 32 percent last year, the worst performance in more than three decades, as the US recession forced down the value of the firm?s equity holdings and derivative bets.

Most of the stock decline happened in the last three months as Berkshire posted a fourth straight profit drop amid sagging insurance results, but the company still beat the 38-percent tumble of the Standard & Poor?s 500 Index, the 14th year in 20 that Buffett outperformed the benchmark.

Just six of 1,591 American stock mutual funds with at least $250 million in assets made money for investors last year, according to data compiled by Bloomberg.

?In 2008, there was nowhere to hide,? said Guy Spier, chief investment officer at Aquamarine Capital Management, which holds shares in the Omaha, Nebraska-based company. ?Berkshire can?t escape the general fate of American businesses. What Buffett tries to do is ensure that Berkshire Hathaway does less badly than other companies.?

Buffett, 78, poured money into stocks as prices fell and increased Berkshire?s pace of deals as the contraction in credit markets hobbled buyout firms.

The stock plunge ?doesn?t make any difference,? Buffett told Fox Business Network last November.

?It?s happened to me three other times,? Buffett said. ?It happened when it went from 90 to 40 back in 1974, and it happened in 1987. It went down 50 percent in 1998 to 2000. I mean, I hope I live long enough so it happens a couple more times.?

Buffett spent about $3.9 billion on equities in the third quarter, making Berkshire the biggest shareholder in ConocoPhillips, the second-largest US refiner. Berkshire announced 12 acquisitions in 2008, compared with eight in 2007, and also agreed to buy $8 billion in preferred shares from Goldman Sachs Group Inc. and General Electric Co.

?Buffett has the opportunity to do what he does best, which is acquire new companies at prices that have him licking his lips,? said Frank Betz, a partner at Warren, New Jersey-based Carret Zane Capital Management, which holds Berkshire shares.

?I don?t think Mr. Buffett is bummed out at all.? Jackie Wilson, a spokesman for Berkshire, didn?t return a call seeking comment.

Most of the top holdings in Berkshire?s stock portfolio, valued at $76 billion as of Sept. 30, declined at least 15 percent in the past three months of 2008. ConocoPhillips plunged 29 percent in the fourth quarter. Coca-Cola Co., Berkshire?s top holding, dropped 14 percent, and no. 2 Wells Fargo & Co. plummeted 21 percent.

Declines in the value of derivatives also pressured Berkshire shares. Buyers of the contracts would be entitled to billions of dollars from Berkshire if four stock indexes dropped below agreed-upon levels on dates beginning in 2019.

Buffett said the liability on the contracts was $6.73 billion at the end of the third quarter. Berkshire had collected $4.85 billion on the contracts and could profit from investing the funds, the firm said. Bloomberg
