But the article notes that “for dedicated value investors and long-time Berkshire watchers, those nerves may not really matter,” and Keefe Bruyette & Woods analyst Meyer Shields says Abel likely sees bets on AI as a long-term bet on the technology’s potential, in line with the “conservatism that would be expected at Berkshire Hathaway.” at the Tahoe-Reno Industrial Center in Sparks, Nevada, October 9, 2026. Hyperscaler’s spending on AI data centers has fueled a surge in technology sector bond issuance. Daniel Cole Reuters At Barron’s, however, Andrew Bary sees what he estimates is a $3 billion loss at Alphabet as part of a “disappointing” long-term trend in Berkshire stock picking. “The company hasn’t created much value from stock picking over the current decade” even though “the S&P 500 has returned 150% since the end of 2019 and tech stocks have quadrupled.” While Berkshire’s investments in five Japanese “trading houses,” Chevron and Chubb have done well, “there have been many losers or just mediocre investments that have closed.” It cites Verizon, HP, Paramount (now Skydance), General Motors, Constellation Brands and Pool.While it estimates Berkshire’s Occidental Petroleum investment is up about 20% from what it paid, OXY is “far behind most energy stocks” amid this year’s big surge in crude oil prices. Bary also lists stocks whose price has continued to rise after Berkshire reduced its holdings, with Apple being the worst offender. That stake has dropped 75% since 2023 to what Bary estimates is an average selling price of about $200 per share, well below AAPL’s current $342.

Power, a unit of Berkshire Hathaway’s PacifiCorp, is asking California regulators for a 57% rate increase that would increase the typical residential electric bill by $120 a month.

He is a 27-year-old shareholder from Kentfield, California. And I have to preface this question by saying that he was here 17 years ago, when he was 10 years old, and he asked you a question from the audience asking if the Internet could hurt some of Berkshire’s investments. At that time, you said you wanted to see how things would develop. You have now updated the question. (Buffett laughs) “What do you think about the implications of artificial intelligence on Berkshire’s business, beyond autonomous driving and GEICO, which you’ve already talked about? And it may not be good for a given business, but let’s take it to the extreme. Suppose a person could press a button and essentially, through various machines and robotics, all kinds of things, generate all the production that we have in this country. So, everyone… there’s as much production as we have, you know, in instead of 150 million people employed, just one. You know, is the world better off or not? Well, we would certainly work a lot fewer hours a week, work weeks, etc. I mean, it would be a good thing, but it would require a huge transformation in the way people relate to each other, what they expect from the government, you know, all kinds of things and, of course, as a practical matter, more than one person would still work. But pushing the idea that way is one of the consequences of making great progress. in artificial intelligence. And that’s enormously prosocial, eventually it’s enormously disruptive in other ways. And it can have enormous problems, in terms of a democracy and how it reacts to that… CHARLIE MUNGER: Well, you’re painting a very funny world where everyone is in commerce. And the commerce is that I give you golf lessons and you dye my hair and the rest of us just do business. iconArrows pointing outExpand iconArrows pointing outBRK.A share price: $856,612.00BRK.B share price: $570.89BRK.BP/E (TTM): 14.35Berkshire market cap: 1,222,245,324,463Berkshire Cash as of June 30: $365.5 billion (down 8.0% from March 31)Excluding Rail Cash and subtracting Treasury bills payable: $359.2 billion (down 3.8% from March 31)Berkshire repurchased $4.5 billion of its shares in the second quarter of 2026.BERKSHIRE’S TOP STOCK HOLDINGS – November 6 2026 Expand icon Arrows point out Top publicly traded stock holdings disclosed by Berkshire in the U.S. and Japan, by market value, based on latest closing prices Holdings are as of June 30, 2026, as reported in Berkshire Hathaway’s 13F filing dated August 14, 2026, except: The complete list of holdings and Current market values are. available on CNBC.com’s Berkshire Hathaway Portfolio Tracker.
