Leadership Changes at Berkshire Hathaway as Todd Combs Departs
Todd Combs, one of Berkshire Hathaway’s (BRK-B) two key stock pickers, is making a notable career move by joining JPMorgan Chase (JPM). This development, according to The Wall Street Journal, coincides with the upcoming retirement of Berkshire’s CFO Marc Hamburg, slated for June 1, 2026. The shift indicates a broader leadership transition within the company.
[Greg] Abel, the company’s vice chairman and the lead executive of its many non-insurance businesses, will take over as chief executive officer in January. And while he hasn’t publicly addressed his plans for Berkshire, Combs’s exit suggests Abel is already beginning to put his stamp on the company, including its massive investment portfolio.
Combs’ departure could be seen as part of the natural ebb and flow of corporate leadership, yet speculation arises that Greg Abel, the incoming CEO, might have influenced this decision. With Combs and Ted Weschler performing similar roles, Abel’s choice reflects strategic consolidation under his leadership.
The individual performance of Combs and Weschler remains undisclosed, as Berkshire does not share specifics on their stock selections. However, Weschler’s pre-Berkshire hedge fund was notably larger and more successful than Combs’, fostering a perception among Berkshire enthusiasts that Weschler outshines Combs.
While Combs’ exit may not alter the core trajectory of Berkshire Hathaway, it does emphasize a looming concern: the potential ripple effect of Warren Buffett’s eventual retirement. Many senior executives, financially secure and past typical retirement age, might follow suit, potentially impacting Berkshire’s operations and market value.
Despite this, the transition could present opportunities. Buffett has admitted to under-managing certain divisions, such as BNSF Railway, which lagged in adopting industry innovations like “precision railroading.” Abel may capitalize on such opportunities to enhance profitability.
The success of this leadership transition hinges on preserving Berkshire’s unique culture, which has historically minimized executive turnover. Buffett remains a central figure, maintaining influence through his significant shareholding and board presence, potentially aiding Abel through this period.
Challenges and Opportunities in the Electric Vehicle Market
Marques Brownlee’s recent review of Xiaomi’s electric vehicle highlights the growing competition for EV giants like Tesla (TSLA). Brownlee describes Xiaomi’s offering as “a ridiculously good car for the price,” spotlighting the threat from Chinese automakers who are rapidly advancing in the EV market.
The U.S. market currently benefits from tariffs and import barriers, but the global landscape is increasingly competitive. Tesla’s potential advantage lies in autonomous driving technology. Although Brownlee’s review lacks detail on Xiaomi’s assisted-driving features, Tesla’s new Full-Self Driving (FSD) v14.2.1 is reportedly impressive, though it remains a driver-assistance program rather than fully autonomous.
Tesla’s approach contrasts with Alphabet’s (GOOGL) Waymo, which has invested significantly in developing 100% autonomous driving. Waymo’s extensive data suggests a significant safety advantage over human drivers, with 91% fewer serious crashes. Tesla’s reliance on cameras instead of lidar raises questions about its ability to achieve full autonomy.
Despite skepticism, Tesla and SpaceX have a track record of defying odds, positioning TSLA as a precarious short bet. However, if Tesla’s autonomous driving ambitions fall short, its valuation might not sustain, given its current $1.5 trillion market cap.
Autonomous Driving: Safety and Data Transparency
A New York Times op-ed by a neurosurgeon highlights the safety benefits of advanced driver-assistance systems like Tesla’s FSD and fully autonomous vehicles like Waymo’s. Waymo’s data reveals a dramatic reduction in crash rates compared to human drivers, particularly at intersections and with cyclists.
Waymo recently released data covering nearly 100 million driverless miles in four American cities through June 2025, the biggest trove of information released so far about safety. I spent weeks analyzing the data. The results were impressive. When compared with human drivers on the same roads, Waymo’s self-driving cars were involved in 91 percent fewer serious-injury-or-worse crashes and 80 percent fewer crashes causing any injury. It showed a 96 percent lower rate of injury-causing crashes at intersections, which are some of the deadliest I encounter in the trauma bay.
This data transparency is crucial, and regulators should mandate similar disclosures from all autonomous vehicle companies before allowing them to operate without safety drivers.
