Dimon poached Buffett's protégé Todd Combs to run $10B fund; Buffett: "at least he's going to you

JPMorgan Chase chief executive Jamie Dimon hired Todd Combs, a former Geico chief executive and Berkshire Hathaway investment manager, to lead a $10 billion investment group. Combs joined in December 2025 under the bank's Security and Resiliency Initiative, which aims to help companies accelerate manufacturing. Speaking at a US Chamber of Commerce event in January, Dimon said he called Warren Buffett personally. Buffett "probably wouldn't have preferred it, but he said, 'if he's going anywhere, at least he's going to you,'" Dimon said. Buffett's assistant confirmed the account. Combs had been at Berkshire since 2010 and sat on JPMorgan's board for nine years. His group has already committed $5 billion of its $10 billion allocation.

Apple tops $5T market cap as Greg Abel keeps 22% of Berkshire's portfolio in the stock

Apple has closed above a $5 trillion market cap for the first time, becoming only the second company to do so. It is also Berkshire Hathaway's top holding, at about 22% of the conglomerate's public equity portfolio. Greg Abel became Berkshire's chief executive officer at the start of the year, after Warren Buffett stepped down. Abel has said he will keep the company culture and its major stock holdings. Apple's fiscal third-quarter revenue, for the period ended June 27, rose 16% year over year to $109.4 billion. Earnings per share rose 29% to $2.02. iPhone sales grew 21.6% to $54.3 billion, driven by the iPhone 17 and its AI features. Apple's installed base has passed 2.5 billion active devices, and it is launching its first foldable phone, the iPhone Duo.

27 S&P 500 stocks just made new 52-week highs.

27 S&P 500 stocks just made new 52-week highs. October 21st, 2026 · by Trefis Team SPYYTD+14.0% SPYYTD+14.0% QQQYTD+18.3% As of Tuesday, October 20, there are 27 S&P 500 stocks trading at their 52-week highs. Berkshire Hathaway (BRK-B), with a market value of about $1.16 trillion, is the largest company on the list; its stock is up 7.5% over the past month and up 9.6% over the past year. Health Care contributed the most names, 12 of the 27. For context, the S&P 500 is down 0.6% over the past month, including dividends. The Biggest Names On The List The table below shows the 10 largest of the 27 names, sorted by market capitalization, with returns over four windows: | Tickers | Market Cap | 1D Return | 1W Return | 1M Return | 1Y Return | | BRK-B | $1,163.1 Bil | 1.4% | 3.7% | 7.5% | 9.6% | | LLY | $1,145.5 Bil | 3.5% | 10.0% | 10.2% | 60.9% | | V | $764.7 Bil | 0.9% | 2.7% | 9.9% | 19.9% | | MA | $547.2 Bil | 0.7% | 2.6% | 9.5% | 11.3% | | ABBV | $511.4 Bil | 2.3% | 6.0% | 10.0% | 29.7% | | CVX | $444.6 Bil | 0.6% | 3.7% | 10.8% | 53.3% | | PFE | $171.6 Bil | 2.3% | 6.1% | 8.5% | 31.5% | | MCK | $122.3 Bil | 1.9% | 7.1% | 16.2% | 31.6% | | ADP | $116.7 Bil | 2.0% | 6.1% | 8.5% | 7.1% | | ELV | $95.5 Bil | 2.3% | 3.5% | 7.5% | 28.7% | Strong Prices, But How Strong Are The Businesses? Berkshire Hathaway (BRK-B) trades at 13.6 times trailing earnings and grew revenue 10.4% over the last twelve months. Eli Lilly (LLY) trades at 42.9 times trailing earnings, grew revenue 49.6% over the last twelve months and earned an operating margin of 49.7%. Across the list, one-month moves range from +4.7% for MetLife (MET) to +24.9% for Hasbro (HAS). The median stock on the list is up 31.6% over the past year. A new high tells you what the market already believes. The harder question is which of these runs management itself is underwriting. Our Guidance Momentum screen tracks exactly that: stocks where the company raised its own forward numbers. One more pattern worth noticing: 12 of the 27 names are Health Care stocks. When a whole group is making new highs together, a health care ETF like XLV, which holds 6 of the 6 largest of them, is one way to own part of the group's strength without betting on which single name leads it from here. Strength Is A Clue. It Is Not A Plan A stock at its 52-week high has momentum on its side, and momentum is a real force. It is also the most crowded signal in the market, and what separates a run that lasts from one that tops is usually the business underneath. Checking that business, across thousands of names, is how the Trefis High Quality (HQ) Portfolio is assembled: roughly 30 companies that pass the quality screens, rebalanced on rules. It has a track record of outpacing a benchmark that combines the S&P 500, the S&P MidCap 400, and the Russell 2000. Let the highs point; let the discipline decide.

Buffett warns of a "gambling mood" in markets; Vertex, Eli Lilly and AbbVie built to weather a drop

Warren Buffett, now Berkshire Hathaway's chairman emeritus, gave his bluntest warning yet at the May shareholder meeting. "We've never had people in a more gambling mood than now," he told CNBC, pointing to individuals rushing into short-term options and betting on markets. He said this behaviour is risky for those taking part and may threaten the market, possibly leading to a drop. The article suggests drugmakers as defensive picks, since patients need treatments in any economy. Vertex Pharmaceuticals leads in cystic fibrosis treatment. Eli Lilly's tirzepatide drugs, Mounjaro and Zepbound, earned more than $14 billion of its $23 billion quarterly revenue. AbbVie's Rinvoq and Skyrizi each grew 24%, and it has raised its dividend for more than 50 consecutive years.
