Warren Buffett, nearing the end of his tenure at Berkshire Hathaway, has made a surprising move: a $4.3 billion investment in Alphabet (Google). Given Buffett's historical aversion to tech stocks—Apple being the notable exception—this raises a critical question: Is this a strategic shift driven by data, or a sentimental play at the close of an era?
The numbers paint a clear picture. Berkshire acquired 17.8 million shares of Alphabet last quarter. Alphabet, with its $3.4 trillion market cap, isn't exactly a small-cap gamble. The stock has surged 46% this year, fueled by the AI boom. Buffett himself has admitted to missing the boat on Google in the past, even saying "we blew it" on one occasion.
However, a closer look reveals a more nuanced situation. Berkshire simultaneously reduced its Apple position by 15%, down to 238 million shares. It also trimmed its Bank of America stake by 6%. This suggests a broader portfolio rebalancing, not just a sudden infatuation with Google. Could it be that Buffett is simply rotating out of positions that have become overvalued in his eyes and into one that, while still tech-heavy, presents a different risk/reward profile?
It's worth remembering that Buffett has two investment managers, Todd Combs and Ted Weschler. The article suggests they may have initiated the Alphabet position. This begs the question: To what extent does this investment reflect Buffett's personal conviction versus the decisions of his team? The answer to that question is crucial to understanding the true significance of this move.
Berkshire's third-quarter earnings further complicate the picture. They spent $6.4 billion on stocks but sold $12.5 billion worth, making them net sellers for the 12th consecutive quarter. This highlights Buffett's struggle to find undervalued opportunities in an inflated market. With a record $358 billion cash pile burning a hole in their balance sheet, (after subtracting Treasury payables), Berkshire had to do something. It's like a general sitting on a mountain of supplies, forced to engage just to deploy resources.

Buffett's impending departure adds another layer of intrigue. Greg Abel, his successor, will inherit the challenge of deploying that massive cash reserve. Is the Alphabet investment a signal of a new direction for Berkshire under Abel's leadership? A move towards tech-driven growth, perhaps? Or is it a parting gift, a high-profile bet to generate immediate returns and pad the portfolio before the handover?
The rise of AI is undeniable. Alphabet's Gemini AI app boasts over 650 million monthly users. Google Cloud's backlog stands at $155 billion, up 46% year-over-year. These aren't just impressive numbers; they represent a fundamental shift in the technological landscape. Even Buffett, with his traditional value investing approach, can't ignore the potential of AI. This is where I start to wonder if Buffett had to buy in, at least a little, to avoid looking like a dinosaur.
But let's not get carried away. Alphabet faces its own challenges. The European Commission is investigating Google's business practices, potentially leading to fines of up to 10% of its global turnover (which was $385.5 billion last year). That's a hefty $38.55 billion risk, even in the context of Alphabet's immense size.
And here’s the part of the analysis I find genuinely puzzling: why now? Why not a year ago, or a year from now? What specific data point triggered this move? Details on the internal models and decision-making processes remain, unsurprisingly, opaque.
Buffett's Alphabet investment isn't a complete departure from his value-investing principles. It's more like a calculated punt—a measured bet on a tech giant with a proven track record and significant growth potential in the AI space. It's not a wholesale embrace of tech, but a pragmatic response to market realities and the looming challenge of deploying Berkshire's massive cash reserves.
