The New Era.

For decades, Berkshire Hathaway was one of the few things investors felt they understood. Warren Buffett bought businesses with durable advantages, held them forever, ignored the noise, and let compounding do the heavy lifting.

The playbook rarely changed.

Now the person holding that playbook is gone.

And this morning, Greg Abel gave the market its first real glimpse of what Berkshire Hathaway might look like without Warren Buffett calling the shots.

The result?

UnitedHealth is out.
Amazon is out.
Mastercard and Visa are out.
Delta and Macy’s are in.

And suddenly, Berkshire looks a lot less predictable.

Here’s the story

How is Nancy Pelosi worth $413 million on a $174,000 salary?

For decades, the revolving door between Washington and Wall Street kept regular folks like you locked out.

Thanks to a brand-new law…

(One Jeff Brown was consulted by Congressional offices on…)

The "Pelosi Paradox" is coming to a swift end.

And it's lighting a fuse under an over $2 quadrillion corner of the tech market.

In what's set to be the biggest wealth transfer in America in 53 years.


Buffett’s Portfolio Is Changing

Every quarter, institutional investors managing more than $100 million are required to file something called a 13F — a public document showing the stocks they owned at the end of the quarter.

Usually, nobody outside Wall Street cares.

But Berkshire Hathaway is different.

For decades, Buffett’s filings were treated like investment scripture. Investors studied every addition, every trim, every quiet exit looking for clues about where “The Oracle of Omaha” thought the economy, valuations, and markets were headed next.

But this filing is different.

Because for the first time in decades… it doesn’t really belong to Buffett anymore.

Greg Abel officially became Berkshire Hathaway CEO on January 1, 2026. This filing — showing holdings as of March 31 — is a first glimpse at whether the new CEO will stay true to Buffett's philosophy or start to put his own stamp on the world's most famous investment portfolio.

This filing is his opening statement.


What Berkshire sold — fully exited

The biggest headline was UnitedHealth.

Berkshire completely exited its roughly 5 million-share stake in UNH — a position Buffett himself only started building last year.

This was not some ancient Berkshire holding quietly fading away over time. This was one of Buffett’s final major bets before handing the company to Abel.

Now it’s gone.

The market noticed immediately.

UnitedHealth fell sharply after the filing became public, despite the company recently beating earnings estimates and raising guidance.

That’s the strange power Berkshire still has over markets:
When Berkshire buys something, investors call it validation.
When Berkshire sells something, investors assume there’s a problem.

Even if the business itself hasn’t fundamentally changed overnight.

After "33X" call, Hall of Fame Trader Jon Najarian reveals NEW Tesla prediction…
Jon Najarian put his neck out on national TV for Tesla in 2014… Before Tesla stock flew to peak gains of 3,392% today! But this "33X" call on Tesla might pale in comparison to Jon's newest prediction about Elon Musk… That a potential $44 TRILLION plan could be coming next.
Click here to see what Jon Najarian is predicting now.

But UnitedHealth wasn’t the only surprise.


Some of those names are especially interesting.

Mastercard and Visa, for example, are exactly the kind of businesses Buffett historically loved — capital-light “toll booth” companies that quietly collect a piece of global commerce every time money moves.

Now both are gone.

Amazon disappearing from the portfolio also stands out because Buffett famously admitted Berkshire was late to big tech. Amazon was one of the rare moments Berkshire fully embraced a modern platform business.

Abel just walked away from it.

Taken together, these moves tell a story Berkshire investors are not used to seeing:

Less permanence.
More repositioning.
More willingness to reverse course quickly.


What Berkshire cut — reduced positions



SPONSOR BREAK presented by BrownstoneResearch*

When Elon Musk ran a Twitter poll in 2021, Tesla lost $30 billion in a single day.

When he changed the Twitter logo to Dogecoin, the coin surged 30% overnight.

No one alive moves markets the way Elon does.

Larry Benedict — the trader who delivered a 279% return on cash in 2025 — says Elon's next move is his biggest yet.

And there's ONE ticker, overlooked by almost everyone, positioned to capture it.

 

What Berkshire bought — new positions

Then came the move nobody expected.

Delta Air Lines.

Berkshire revealed a new 39.8 million-share stake in the airline giant — a remarkable decision considering Buffett famously dumped every airline holding during the pandemic and publicly admitted the investment was a mistake.

Buffett spent years avoiding airlines because of their brutal economics:
cyclical demand
razor-thin margins
fuel price shocks
labor costs
constant competition

Abel clearly sees something differently.

Maybe it’s a bet on consumer resilience.
Maybe it’s confidence in post-pandemic travel demand.
Maybe he simply believes the industry structure has improved.

Whatever the reason, the symbolism matters.

The Bigger Shift

The most important thing about this filing is not any individual stock.

It’s the tone.

For decades, Berkshire investors felt like they understood the rules:
Buy great businesses.
Ignore short-term noise.
Hold forever.

Greg Abel’s first filing introduces something new: unpredictability.

And markets are still trying to figure out whether that is exciting… or dangerous.

1\ Maybe Abel saw risks in UnitedHealth Buffett underestimated.
2\ Maybe Delta becomes one of Berkshire’s best-performing positions over the next decade.
3\ Or maybe the new CEO simply wanted to make one thing unmistakably clear from the beginning:

This is his portfolio now.

And the new manager just introduced himself.
