Warren Buffett’s Berkshire Hathaway rallies to record high on earnings beat

The more thinly traded Class A stock also set a closing record, at $551,920.

The B shares are now up about 17 percent this year, around even with the S&P 500 Index.

The firm’s results showed a jump in insurance underwriting earnings, which included a benefit from its acquisition of Alleghany Corp. The Federal Reserve’s campaign of interest-rate hikes also helped, by boosting Berkshire’s investment income from the cash it stockpiles in short-dated US Treasuries.

“Operating company earnings of about $9 billion were better than we expected as strength in insurance, including favorable reserve development at Geico and higher fixed investment income, offset a drop in railroad earnings,” Bloomberg Intelligence analyst Matthew Palazola wrote in a report.

As the largest S&P 500 stock outside of the tech giants, Berkshire’s record high highlights the breadth of the market’s rally and the depth of optimism for the US economy.

The Omaha, Nebraska-based holding company operates and invests in all corners of the US economy, well beyond its core insurance businesses like Geico. Businesses ship their goods along thousands of miles of BNSF rail routes. Consumers live in Clayton Homes communities, coat their walls with Benjamin Moore paint and eat Dairy Queen blizzards.

“You can make the argument that Berkshire is kind of a microcosm for the broader economy and indeed maybe the broader market,” Cathy Seifert, an analyst at CFRA, said by phone.

This year, Berkshire shares have bounded higher alongside the broader market. The stock of Apple Inc., which touched a market capitalization of $3 trillion this year, has been one driver.

The tech giant makes up the largest holding in Berkshire’s equity portfolio, and the roughly 38 percent surge in Apple shares this year helped expand that value.

“Apple ripping higher this year is certainly directionally positive for Berkshire stock,” Shanahan said. “It’s not the only thing that should be driving the shares here.”
