Warren Buffett's Berkshire Hathaway reveals new stake in beleaguered insurer UnitedHealth
The Omaha-based conglomerate bought more than 5 million shares in the health care firm for a stake worth about $1.6 billion at the end of June. The stake puts it as the 18th biggest position in the Berkshire portfolio behind Amazon and Constellation Brands, according to VerityData.
Berkshire's equity portfolio is worth about $300 billion, so it is possible that Buffett's two investing lieutenants Todd Combs and Ted Weschler were more responsible for this purchase rather than the 'Oracle of Omaha' himself. Buffett said one of his investment managers was behind the Amazon investment in 2019.
The insurer's stock shot up 6% in extended trading following Berkshire's disclosure.
Shares of UnitedHealth were down nearly 50% for 2025 through Thursday's close before Buffett's filing. The largest private health insurer has become the face of a public blowback in this country against the rising costs of health care. UnitedHealth is currently facing a Justice Department investigation into its Medicare billing practices.
In May, the company pulled its annual earnings outlook and CEO Andrew Witty stepped down. Last month, UnitedHealth gave a new 2025 outlook that was well short of Wall Street estimates, hitting the stock further.
Buffett, who's turning 95 this month, has been critical of the healthcare system in the U.S., calling it a 'tapeworm' on the economy due to its high costs. In 2018, he, along with Jeff Bezos and Jamie Dimon, launched a joint venture to improve healthcare for their employees and potentially for all Americans, but it was eventually shut down.
UnitedHealth isn't the only stock Berkshire picked up recently. In fact, the conglomerate also took small stakes in steel manufacturer Nucor, outdoor advertising company Lamar Advertising and security firm Allegion. Berkshire also got back into homebuilders Lennar and DR Horton.
Shares of Nucor jumped nearly 8% in afterhours trading, while Lennar and DR Horton popped about 3% each.
Buffett also pared his positions in Bank of America and Apple. The Apple stake was cut by about 7%. Berkshire's largest positions as of the end of the second quarter were Apple, American Express, Bank of America, Coca-Cola and Chevron.
The legendary investor is stepping down as Berkshire CEO at the end of the year, handing over the reins to Greg Abel. Buffett will stay on as chairman of the board. It's still unclear who will be in charge of Berkshire's gigantic equity portfolio, though Buffett has alluded that Abel will be making all capital allocation decisions at the conglomerate.
UnitedHealth attracted other buyers last quarter, according to filings, including Michael Burry and Appaloosa Management's David Tepper. Shares of the insurer are trading at a price-earnings ratio of just under 12, near its lowest in more than a decade.
There was speculation regarding a mystery stock Buffett was buying as Berkshire had asked for permission to keep certain holdings secret last quarter. It turns out the secret stock was a combination of multiple positions and likely the stakes added in DR Horton, Nucor and Lennar 'A' shares.

Warren Buffett Just Bought 6 Brand-New Stocks -- Here's Exactly What They Are
Key Points During the second quarter, Berkshire sold several stocks, including more of its Apple and Bank of America stakes. Buffett and his team added to six existing positions and started six brand new ones. Most of the new positions have been beaten down or generally look cheap. 10 stocks we like better than Berkshire Hathaway › When Berkshire Hathaway (NYSE: BRK.A)(NYSE: BRK.B) released its second-quarter earnings, it was revealed that the Warren Buffett-led conglomerate had been a net seller of stocks. But that didn't come close to telling the whole story. In the company's just-released 13-F filing with the Securities and Exchange Commission (SEC), investors got an updated look at Berkshire's portfolio. And to be clear, Berkshire was a net seller of stocks. However, this was primarily because of three specific moves: Berkshire sold another 20 million shares of Apple, worth about $4.6 billion at current prices. The Bank of America investment was trimmed by another 26.3 million shares, worth about $1.25 billion. Berkshire completely closed its T-Mobile investment, selling 3.88 million shares, worth about $1 billion. These sales aren't too surprising. But what was a bit of a surprise was that Buffett and his team added to six existing positions and also bought six brand-new stocks in the massive portfolio. Here are Berkshire's six new stocks Here's a rundown of the six new stocks that were added to Berkshire's portfolio in the second quarter: Company (Symbol) Shares Purchased Current Market Value UnitedHealth Group (NYSE: UNH) 5,039,564 $1.57 billion Nucor 6,614,112 $857 million Lennar (NYSE: LEN) 7,048,993 $780 million D.R. Horton (NYSE: DHI) 1,485,350 $191 million Lamar Advertising 1,169,507 $142 million Allegion 780,133 $112 million Data source: Berkshire Hathaway 13-F. Share counts as of 6/30/2025 and market values as of 8/15/2025. Before we go on, there are a few things worth noting. First, we don't know whether these purchases were made by Warren Buffett himself, or one of Berkshire's two other investment managers, Ted Weschler and Todd Combs. Also notice that although these are six brand-new positions, they add up to about $4 billion, significantly less than the proceeds from the Apple, Bank of America, and T-Mobile sales, which is how Berkshire was still a net seller of stocks for the quarter. It's also possible that Berkshire will continue to build some of these positions. As an example, one of the stocks Berkshire first added to its portfolio late last year, Pool Corp., was one of the largest additions to an existing position during the second quarter. When we get a glimpse of Berkshire's third-quarter buys and sells later this year, I wouldn't be surprised to see at least a few of these positions have grown significantly. Why did Berkshire buy these stocks? We don't know exactly why Buffett and his team decided to add any of these stocks, and it would be rare for him to comment on his investment thesis for any of them. But generally speaking, these all look like rather cheap stocks right now, especially considering that the S&P 500 and Nasdaq are near all-time highs. In the case of UnitedHealth, it's no secret that the business has struggled lately. Between rising medical costs, regulatory turmoil, and several other issues, UnitedHealth -- the largest health insurer in the United States -- has fallen by nearly 50% in 2025 before Berkshire's purchase was announced. You'll also notice that there is not one, but two homebuilders on the list, Lennar and D.R. Horton. Conditions for these companies are not great right now, as mortgage rates remain high and the market has been agonizingly slow. But these are two of the largest and most financially sound builders in the industry, and they trade for price-to-earnings (P/E) multiples of just 10.8 and 12.4, respectively. The bottom line is that even though the stock market as a whole might look a little expensive right now, Buffett and Berkshire's investment managers seem to think there are some stocks that are attractive bargains right now. It will be interesting to see if Berkshire keeps adding to these (and any other) stocks in the third quarter, as the market has rallied significantly in the roughly one and a half months since the second quarter ended.

Buffett's Berkshire Hathaway sold Apple shares. Should you?
Warren Buffett's Berkshire Hathaway (BRK-B, BRK-A) sold 20 million shares of Apple (AAPL) in the second quarter. Slatestone Wealth chief market strategist Kenny Polcari, Nomura chief economist David Seif, and Yahoo Finance Senior Reporter Allie Canal join Opening Bid host Brian Sozzi to discuss whether investors should follow suit and sell their Apple shares as well. To watch more expert insights and analysis on the latest market action, check out more Opening Bid. Warren Buffett's Berkshire Hathaway sold 20 million shares of Apple during uh the period according to uh new 13F filing. Berkshire's Apple holdings remain its largest equity stake by market value despite it dropping by about 9.2 billion dollars in the second quarter. So, my question is this, if the legendary Warren Buffett is selling tech titan Apple, should you, Kenny? 100% absolutely not. You're not going to make a decision just because because you have to look at what he's selling, where does he own it. Look, when he sold Bank of America back when it was trading at 39 and 40, everyone was going, oh my god, he sold Bank of America, I have to get out of my Bank of America. Bank of America is trading at $48 now. You have to look at where he bought it. He bought it at five during the crisis. It hit his price target, so he started to sell it out. That's not necessarily your price target unless maybe you bought it at five as well, and then you decide you want out. But, I would not be making a decision to own or not own my Apple based on what Warren Buffett's going to do. Like you said, it is still the biggest piece of his whole portfolio. So, I am not selling my Apple. All right, Kenny, you're clearly fired up on this. Let me follow it on with this one. Have we reached the moment where the average investor should ignore what Warren Buffett is doing? Well, listen, I think what the average investor has to do is, they can't necessarily think that they are the same as Warren Buffett. They shouldn't be planning their life around what Warren Buffett's doing. He's got a very different company. He's been in for a lot longer. Your situation is different from his situation. So no, I was never in the camp that you're going to build a portfolio around what Berkshire Hathaway's doing. So, I was never in that camp. So, no, I don't think you should. Uh David, um on Apple. Now look, they, they did warn in this current quarter, they might see a $1.1 billion hit because of tariffs. How concerned are you about the third quarter uh tariff impact and what it is going to do or may already be doing to the financial statements of corporate America? Well, you know, I I think it it's still unclear who exactly is paying the cost of these tariffs. I mean, we could easily be collecting 300, 400 billion uh dollars a year in uh in tariffs, and uh you know, it's a substantial amount, but it's got to come from somewhere. Uh we're not really seeing it all that much at least as of yet in the uh consumer price index. So, um consumer might be paying a little bit of it, but certainly not much. So, the question is, how much of it is uh domestic companies, and how much of it is is foreign companies? And and in the case of Apple, yes, it's a domestic company, but since it's producing uh overseas and then selling it here, uh if it's not the consumer, then it's got to be uh Apple in some form. So uh and and and not just Apple, but sort of, you know, companies in general. So, certainly it looks as though um given that we're collecting a lot of money and prices haven't gone up that much, um this is something where um it is going to hit the bottom line of companies in general. Ali, uh Kenny brings up a great point. Um we may think we could pick a stock like Warren Buffett, but at the end of the day, we're not Warren Buffett. We don't have his billions. Maybe Kenny has his billions, but we don't have his billions. We can't move markets like he does. So, maybe we should just stop following them. Well, you know, look, Warren Buffett is such a loved investor, and people have really looked at Berkshire as a a guiding light on how to guide different types of investment strategies. And Warren Buffett, one of his philosophies is, buy what you know. What do we do? We are constantly on this phone every single day. So, you are exposed to Apple. You see what it does, the innovation that it brings. Now, the ironic part about all of this is that's why the stock has been struggling. It's because the innovative side, the AI side of the equation just has lagged a lot of those competitors. But Apple historically, they're not the innovator, right? Other companies innovate, then they come in, and they just build and make a better product. And for Apple, the AI story is going to be more of a consumer story, and I just don't think we're there yet at this point. Right now, it's more focused on chips. It's more focused on B2B. Of course, the large language models at Chat GPT, that's something that everyday consumers are using more and more, but I think there there's still a lot more of the story to come when it comes to AI and how Apple can really utilize that in the future. Right now, it's not there for investors. That's why the stock is down about 7% since the start of the year, but you know, it's still something that you need to watch because I do think Apple can maybe surprise in the next year or so. So Ali, what you're telling me is I need to go out and buy some Tyson Foods because I eat a lot of chicken. Brian, let me ask you one thing. If people want to play that game, and they want to do what Warren does, just go out and buy Berkshire Hathaway, and then you're going to do exactly what Warren does. My favorite panel of the week. I mean, you guys killed it.

UnitedHealth stock pops on Buffett's Berkshire share purchase
UnitedHealth Group's (UNH) stock jumped early Friday after Warren Buffett's Berkshire Hathaway (BRK-A, BRK-B) revealed Thursday it purchased 5 million shares last quarter. The insurance giant has suffered multiple setbacks in the past couple of years — with earnings misses piling on top of all that, the stock has been under constant pressure, and is down more than 45% year-to-date. But on the news of Berkshire's share purchase, the stock popped nearly 10% in early trading Friday. The last time Berkshire held a stake in the company was when Stephen Hemsley was CEO, between 2006 and 2017. Hemlsey has returned to the role after former CEO Andrew Witty stepped down in May — after a year of compounding headwinds. Last year, the company suffered one of the biggest cyberattacks in history on one of it's subsidiaries, Change Healthcare, which manages payments — creating havoc for health providers for months. The US Health and Human Services Department (HHS) had to step in and assist to help get payments flowing again. The company subsequently announced a larger-than-expected impact from the attack in mid-2024, dragging down major indices. At the end of the year, during the annual shareholder's meeting in New York City, insurance CEO Brian Thompson was shot to death. The struggles for the company didn't end there, as public backlash against the industry swelled in the aftermath, and the entire insurance industry was forced to address the issue of denied claims. In April this year, the company's stock crashed after an earnings miss shocked the Street. In May, Hemsley took over, and in the latest earnings call addressed the missteps the company has made, as well as the higher cost environment that it did not adjust in time to. "Beyond the environmental factors that are affecting the entire sector and more specifically to us, we have made pricing and operational mistakes as well as others," he said on the call. UnitedHealth's stock pop also helped boost the Dow (DJI), which was up about a half percent in early trading. Previously, UnitedHealth's losses dragged the Dow. In May, UnitedHealth was attributed with 88% of the Dow's decline year-to-date.
