The Warren Buffett imprint is not all that visible these days

Berkshire Hathaway’s increasing tech and airline exposures suggest paradigm shift

What makes a good Berkshire Hathaway Inc investment? With the exception of Warren Buffett and his deputies, nobody knows anymore.

It wasn’t all that long ago that there existed the quintessential Berkshire investment. You know the kind.

Whether in the form of a public stake or a full-out acquisition, Berkshire’s shopping history is full of moments that left onlookers thinking, “Yup, that’s so Buffett”.

It’s undeniable that his past stock picks and takeover targets like Coca-Cola Co., the BNSF railroad, Dairy Queen, Deere & Co. and the Pilot Flying J truck-stop chain had Buffett written all over them.

He’s long sought “simple” businesses that he could understand, with durable, if not beloved, brands.

Lately, though, many of Berkshire’s investments haven’t seemed to fit into that Buffett mould. Technology companies never used to be on Buffett’s radar because, as he put it in his 1999 letter to shareholders, he had “no insights” into which ones possessed a true competitive advantage. But less than two decades later, tech giant Apple Inc. is the company’s biggest holding, a position now worth about $50 billion (Dh183 billion).

It has disclosed more curious moves: Berkshire took a new stake in software maker Oracle Corp., dumped Walmart Inc., and bought more shares of Delta Air Lines Inc. — another industry he had at one time sworn off.

It could be that with so much of Buffett’s typical investing universe having been disrupted by technology and changing customer needs, the old stalwarts just aren’t as attractive as they once were. The tech industry that Berkshire avoided for so long now comprises the world’s most valuable companies, and they’re shaking up most other sectors. There’s also the fact that Buffett has entrusted Todd Combs and Ted Weschler with more investing decisions. They’re obviously putting their stamp on things, and Buffett is by all indications fine with that.

But then, does the same old Buffett-y criteria still apply to Berkshire’s future megadeals? One would think what makes a good Berkshire stock investment and what makes a good Berkshire acquisition should be similar.

Whatever the case may be, investors can take comfort knowing that whatever it is Buffett and his team are up to nowadays, it’s probably still smart.
