The trillion-dollar conglomerate that Warren Buffett built has entered a new era. On Dec. 31, Warren Buffett retired as CEO of Berkshire Hathaway (NYSE: BRKA)(NYSE: BRKB), handing the proverbial keys and control of the company’s day-to-day operations and mammoth investment portfolio over to Greg Abel.

Following the closing bell on Friday, May 15, Wall Street and investors got their first look at what an Abel-led portfolio might entail — and it involved a massive overhaul. Abel completely sold out of Amazon (NASDAQ: AMZN) and Domino’s Pizza (NASDAQ: DPZ), the latter of which had been purchased for six consecutive quarters, while more than tripling Berkshire’s stake in virtual monopoly Alphabet (NASDAQ: GOOGL)(NASDAQ: GOOG).

There’s no mistaking that this is Greg Abel’s portfolio now

When the dust cleared on April 1, Form 13F filings show that Abel completely exited 16 positions (a third of Berkshire’s portfolio, including its stakes in six Japanese stocks) during the first quarter.

The Amazon sale was, arguably, telegraphed following a 77% reduction in the December-ended quarter. Though Amazon possesses a sustainable moat and strong management team, something Abel and Berkshire’s former boss often looked for in great investments, it isn’t a screaming fundamental bargain, which is what Abel is seeking.

The sale of Domino’s Pizza stock is a true shock after six consecutive quarters of purchases. However, the adverse effects of inflation on consumers in the food industry may be at play. While Domino’s food speaks to value-conscious consumers, it nevertheless reported subpar same-store sales growth in the U.S. of 0.9% and an ultra-rare decline in international same-store sales (down 0.4%) in the first quarter.

In addition to Amazon and Domino’s, longtime holdings Visa and Mastercard were shown the door, UnitedHealth Group was dumped, and Berkshire’s stake in Chevron was cut by 35%.

Warren Buffett’s successor piles into Google parent Alphabet

While there were a few notable new additions, including Delta Air Lines and department store retailer Macy’s, and a near-tripling in The New York Times Co., it’s Abel’s hand over fist buying of Google parent Alphabet that really stands out.

Abel more than tripled Berkshire Hathaway’s existing stake in the Class A shares (GOOGL) by purchasing 36,403,656 shares, and also added 3,585,215 Class C shares (GOOG). Collectively, Berkshire’s stake in Alphabet is worth approximately $23 billion, as of May 15.

Most investors are familiar with Google, which holds a virtual monopoly on internet search traffic (roughly 90% of worldwide traffic). But Alphabet is much more than search. It’s the parent of YouTube, the second-most-visited website behind Google, and is the brains behind the world’s No. 3 cloud infrastructure service platform by total spend, Google Cloud.

Google Cloud is the fastest growing hyperscaler in the entire world.

Alphabet’s incorporation of artificial intelligence solutions into Google Cloud has led to rapid acceleration in this segment’s high-margin growth rate (63% in the first quarter compared with the previous year).

Whereas Warren Buffett never really cared to delve into the inner workings of tech stocks, we’re seeing that his protégé isn’t afraid to dive in headfirst.

One thing is for certain: This isn’t your grandparents’ Berkshire Hathaway anymore.
