The large reduction in the number of stocks in Berkshire Hathaway's equity portfolio that was revealed in last Friday's first quarter 13F SEC filing was perhaps bigger than expected but it wasn't a total surprise.
The Wall Street Journal had reported new CEO Greg Abel would be selling many or all of the stocks formerly managed by Todd Combs, who left for a job at JPMorgan late last year.
It's harder to explain how the two new names, Delta Air Lines and Macy's, got into the portfolio.
Berkshire almost never reveals who makes buy and sell decisions for individual stocks, but the rule of thumb had been Warren Buffett handled the larger positions, and one of the two (now one) portfolio managers were responsible for the smaller positions.
Abel, who now has overall responsibility for the company's investments, replaces Buffett in that construction.
The Oracle, however, is still coming into the office five days a week as chairman, and in late March he told CNBC's Becky Quick he is still making investment calls but won't do anything Abel thinks is "wrong."* *
Presumably, Abel also wouldn't do anything that Buffett opposes.
That makes the reintroduction of Delta to the portfolio after a six-year exile something of a mystery.
Buffett, who suggested in early 2008 that a "farsighted capitalist" should have shot down Orville Wright at Kitty Hawk, would presumably be unwilling to give an airline stock a third chance after a troubled 1989 US Airways investment and a money-losing 2016 return to the sector that he dropped in 2020 at the start of the Covid-19 pandemic.
And, in fact, the Wall Street Journal reported Monday that Buffett told the paper he wasn't involved in the Delta decision.
But it added Berkshire "can't seem to quit its love affair with airlines" as Abel showed "an early fondness for them, too."
Writing for The Motley Fool, Geoffrey Seiler was disappointed that Abel appeared to be repeating Buffett's mistakes.
At Barron's, though, Andrew Bary thinks Delta was "likely" a purchase by Ted Weschler, Berkshire's remaining portfolio manager.
At $2.6 billion, as of March 31, it "exactly matches the increased authority of about $3 billion that he got this year as his responsibility went to 6% of the portfolio from 5%, based on Abel's comments in his annual letter."
Bary also notes Weschler "has a value bent, and Delta is the industry leader valued at around 10 times earnings."
Either way, it is at least a short-term success.
The Delta holding is now valued at $3.0 billion, a 14.5% increase from the end of the first quarter.
That includes an 8.4% jump this past week to a record-high close of $76.14.
Berkshire's new Macy's position is also a short-term win, but the total value is just a fraction of the Delta buy.
It's gone from $55 million as of March 31 to $63 million now, an increase of 14.2%, including a 12.2% rally this week.
Usually, a position that accounts for less than 0.02% of Berkshire's equity portfolio would be seen as the work of a portfolio manager.
But in that March interview with CNBC, Becky asked him if he is still making new purchases and he replied, "Got one tiny purchase, but we aren't finding things that — we weren't finding them before."
CNBC thinks he may have been referring to the Macy's stake but notes he could also have been talking about an international purchase or other investment that would not have to be included in the 13F filing.
Barron's also believes Buffett's comment could have been a reference to the Macy's position.
It sees the retailer's "significant real-estate holdings" as a plus and recalls that in 2015, Buffett personally bought for his own account an 8% stake in Seritage Growth Properties, which controlled stores and real estate spun off by Sears.
"It would be notable if the Macy's buy was done by Buffett. It would show that at 95, he still loves the investment game and can't resist a bargain-priced stock even if the size of the holding is too small to matter at Berkshire."
Two new filings in Japan show Berkshire is continuing to build its positions in at least two of the country's enormous "trading houses."
Its Mitsubishi stake increased to 11.1% as of April 30, up from 9.7% previously, and its Sumitomo stake rose to 10.3% as of May 12, up from 9.3%.
Abel has been involved in Berkshire's Japanese investments for the past several years and almost certainly is behind the additional purchases.
Berkshire may be buying more shares of its other Japanese stocks but only needs to file updates when a holding ratio increases by 1% or more.
The total value of the six stocks, as currently disclosed, is almost $46 billion.

Four leading AI models discuss this article
"Ambiguity over who bought Delta and Macy's weakens the case that Berkshire's investment process remains disciplined after Buffett's de facto retirement from stock-picking."
Berkshire's Q1 13F reveals a leaner U.S. equity book under Abel, with Delta ($2.6B) and Macy's ($55M) as the only new names. The Delta addition revives a sector Buffett publicly scorned after 2020 exits, while the Japan stakes (Mitsubishi to 11.1%, Sumitomo to 10.3%) show continuity. Short-term mark-to-market gains of 14%+ mask the core issue: decision rights are now split among Abel, Weschler, and a still-active Buffett, creating opacity around process and risk tolerance. The $369B adjusted cash pile and modest buybacks remain the dominant capital-allocation signal.
These holdings are <0.3% of the equity portfolio and could be Weschler's discretionary bets within his new 6% limit, not Abel's strategy; the article overstates any shift in Berkshire's overall posture.
"The Delta purchase is a distraction; the real thesis is whether Berkshire's $46B Japan bet and willingness to deploy cash into cyclicals signals confidence in Abel's judgment or a retreat from Buffett's discipline."
The portfolio churn—Combs' positions liquidated, Delta and Macy's added—signals a genuine leadership transition, not continuity theater. But the article conflates two separate questions: (1) Is Abel competent? and (2) Are these specific bets sound? Delta at 10x earnings looks reasonable on surface, but airlines are cyclical and Buffett's 2020 exit was prescient on structural headwinds (fuel, labor, capital intensity). The real tell: Berkshire's cash position fell 2.2% Q1-to-Q4, yet they're deploying into Japan trading houses and cyclical equities. That's either conviction or desperation. The Japan move—Mitsubishi to 11.1%, Sumitomo to 10.3%—matters more than Delta noise: it's a $46B bet on currency, demographics, and governance reform in a structurally challenged economy.
If Abel is genuinely making independent calls and they're already outperforming (Delta +14.5% in weeks), maybe the article's skepticism is misplaced—this could be early evidence of a successful succession, not a warning sign of drift.
"Berkshire's aggressive expansion into Japanese trading houses signals a strategic shift away from domestic equity exposure toward yield-heavy, international value plays under Greg Abel."
The market is over-indexing on the 'mystery' of Delta and Macy's, missing the real story: Berkshire's structural pivot toward Japan. With $46 billion invested in trading houses, Berkshire is effectively hedging against domestic overvaluation and currency volatility. The Delta/Macy's buys are likely 'noise'—small-cap bets by Weschler or Abel to maintain a value-oriented pipeline while Buffett winds down. At a 14.5x TTM P/E, Berkshire isn't cheap, but the massive $369 billion liquidity position provides a defensive moat that justifies a premium. The transition to Abel is clearly favoring capital allocation in stable, dividend-paying international assets over high-growth domestic retail or cyclical airlines.
The 'Japan pivot' may simply be a yield-chasing strategy that ignores the systemic risk of a weakening Yen and stagnant Japanese economic growth, potentially trapping capital in low-growth conglomerates.
"Berkshire's latest moves point to a calibrated, globally diversified value bias with selective concentration, not a Buffett-style reboot into airlines."
Takeaway: Berkshire's 13F shows Abel expanding in Japan and Ted Weschler backing a Delta bet, while Macy's remains a tiny test. That hints at a disciplined reallocation: pare the number of holdings, concentrate in high-conviction ideas, and lean into long-run value opportunities abroad where Berkshire can leverage scale. The Delta move is controversial only if you assume Buffett's airline bias is dead; instead it's a measured, modest weighting that could become a larger bet if travel demand and yields hold up. The real missing context is Berkshire's overall liquidity cushion and the timing of 13F snapshots; these are late-cycle bets, not a blueprint for a Buffett reboot.
Delta could be a tactical, one-off bet driven by Ted Weschler's mandate, not a new airline thesis Berkshire can ride through a cycle. If travel demand stumbles or fuel costs spike, this single name could disproportionately hurt Berkshire's portfolio and mislead readers about its true risk posture.
"Delta's addition exposes fragmented allocation, not a coherent Japan-led pivot."
Gemini treats Delta/Macy's as irrelevant noise against the Japan pivot, yet these additions under Weschler's 6% limit directly illustrate the split decision rights Grok flagged. Pairing that with Claude's cash deployment note shows capital moving into both stable trading houses and cyclical U.S. names simultaneously, which risks inconsistent risk tolerance rather than any unified Abel strategy.
"Delta's post-filing outperformance is a lagging indicator of market sentiment, not proof of Abel's stock-picking skill; cyclical timing risk is the real test."
Claude nails the real tension: if cash fell 2.2% while deploying into cyclicals AND Japan, that's not hedging—it's dual-track conviction or confusion. But nobody's addressed the timing risk: 13Fs lag reality by 45 days. Delta's +14.5% gain post-filing could reflect market enthusiasm for travel, not fundamental strength. If yields compress or fuel spikes Q2, that 'early evidence of successful succession' becomes a cautionary tale. The Japan bet is defensible; Delta's sizing and entry point deserve skepticism.
"The obsession with small-cap airline bets distracts from the systemic currency risk inherent in Berkshire's massive Japan-focused capital allocation."
Claude, your focus on the 2.2% cash dip ignores the elephant in the room: Berkshire's $369B liquidity is so massive that a 2.2% move is statistical noise, not a strategic pivot. The real risk is the 'Japan trap' Gemini mentioned. If the Yen continues its volatility, those trading house dividends are effectively wiped out by currency translation losses. We are over-analyzing small-cap Delta bets while ignoring the macro-currency exposure that actually dictates Berkshire's book value.
"The 13F snapshot plus Delta's gains don’t prove durability; currency risk in the Japan bet and vague governance controls threaten Berkshire’s risk balance more than the surface narrative suggests."
Claude, your takeaway hinges on Delta and Japan as signals of succession; but the 13F lag means the portfolio's current composition could flip if travel demand softens or fuel costs spike. Delta's +14.5% post-filing might reflect market enthusiasm, not durability. More crucially, the Japan bet introduces currency translation risk that could erode equity value despite visible stakes. Absent clearer governance and risk controls, this looks more fragile than you imply.
Berkshire's 13F reveals a shift towards Japan under Abel's leadership, with Delta and Macy's as smaller, controversial bets. The split decision rights and cash deployment raise concerns about risk tolerance and timing.
