Warren Buffett’s Berkshire Hathaway Just Did This for the First Time in 15 Quarters. History Offers a Clue About What’s Next, But the Evidence Piling Up Suggests History May Not Repeat Itself.

Berkshire Hathaway turned net buyer of stocks in Q2 2026 for the first time in 15 quarters, purchasing nearly $20 billion in equities. The conglomerate significantly increased its position in Alphabet during the quarter, marking a notable shift from six consecutive years of net selling.

The buying spree breaks a pattern that stretched back to early 2022. Historically, Berkshire's pivot to net buying preceded market rallies—the last instance in 2022 came ahead of gains. This time, however, market conditions differ sharply. Stocks are trading at valuations approaching dot-com bubble levels, while tariff headwinds and geopolitical tensions cloud the economic outlook.

Warren Buffett's firm has been a consistent net seller since Q3 2022, making the Q2 2026 reversal particularly significant. The Alphabet stake expansion represents one of the largest additions to the portfolio during the quarter. Despite the historical precedent for post-buying rallies, current elevated valuations and macroeconomic pressures suggest a different trajectory may unfold.
