In a significant shift for Berkshire Hathaway, the investment conglomerate founded by Warren Buffett, new CEO Greg Abel has embarked on a bold reallocation of its substantial portfolio. Since taking the reins on December 31, 2025, Abel has demonstrated a clear strategic vision, notably reducing the company's long-standing position in oil giant Chevron while aggressively expanding its stake in Google's parent company, Alphabet. This move signals a potential pivot in Berkshire's investment philosophy, embracing the rapidly evolving technological landscape, particularly artificial intelligence.
The first quarter saw Abel initiate a substantial overhaul, divesting from sixteen different equities and paring down six others, with Chevron experiencing the most significant reduction. The decision to decrease Berkshire's Chevron holdings by 35% involved offloading over 45 million shares. While a portion of this reduction might be attributed to opportunistic profit-taking, given Chevron's impressive stock rally from $152 to $207 during that period, further factors likely influenced the move.
Beyond simple profit realization, the timing of Chevron's stock surge, driven by elevated crude oil prices amid geopolitical tensions, may have presented a strategic exit point for Abel. Historically, disruptions in energy supply tend to be temporary, making the sustained high valuation of cyclical companies like Chevron potentially unsustainable. Furthermore, Chevron's forward price-to-earnings ratio, which had previously hovered around 10-11, climbed to nearly 18 by the end of the first quarter. This increased valuation, coupled with Abel's known preference for value-oriented investments, likely made Chevron a less attractive proposition for the new leadership at Berkshire Hathaway.
Conversely, Abel's fervent acquisition of Alphabet shares has dramatically reshaped Berkshire's portfolio. In the first quarter alone, Berkshire acquired over 36 million Class A shares and nearly 3.6 million Class C shares of Alphabet, more than tripling its previous investment in the tech behemoth. This aggressive accumulation continued with Berkshire's participation in Alphabet's $84.75 billion equity offering, committing $10 billion to the purchase. By the end of July, Alphabet represented a nearly $30.8 billion position, solidifying its place as Berkshire's fifth-largest holding.
Alphabet's enduring strength lies in its commanding presence in the digital advertising realm. The Google search engine maintains over 91% of global internet search traffic, and YouTube ranks as the second most visited social media platform. This dual dominance grants Alphabet considerable pricing power for its advertising services. However, what truly fuels Abel's enthusiasm, drawing parallels to Warren Buffett's long-term conviction in Apple, is Alphabet's burgeoning ambitions in artificial intelligence. The integration of generative AI and large language models into Google Cloud, the third-largest cloud infrastructure service globally, has propelled its sales growth into an exponential trajectory, promising significant future valuation and cash flow expansion for the company.
The strategic adjustments implemented by Greg Abel at Berkshire Hathaway underscore a forward-looking approach to investment. By divesting from a traditional energy giant whose valuation was nearing its peak and aggressively investing in a technology leader at the forefront of AI innovation, Abel is actively shaping Berkshire's future portfolio to capitalize on emerging market trends and maintain long-term growth.
