Berkshire Hathaway broke its 14-quarter streak of net stock selling in the second quarter, deploying approximately $23.5 billion on equity purchases against roughly $3.7 billion in sales, according to the company's filing submitted Aug. 8. The reversal marks the first time since Q4 2022 that Berkshire bought more stock than it sold—a span that outlasted Warren Buffett's tenure as chief executive.

Market Context

The shift comes as Berkshire accumulated its largest-ever cash pile of $397.4 billion at March 31, then watched that reserve fall to $365.5 billion by quarter-end. The massive deployment coincides with a broader rotation into equities among institutional investors seeking exposure to AI-driven growth, while the Federal Reserve's rate trajectory remains a focal point for market strategists.

Analysis

The centerpiece of Berkshire's Q2 buying was a $10 billion private placement in Alphabet as part of the Google parent's $84.75 billion equity raise for its artificial intelligence buildout. Unlike public investors who paid $355.1982 per Class A share and $351.8018 per Class C share, Berkshire secured its position at $351.81 for 14.2 million Class A shares and $348.20 for roughly 14.4 million Class C shares—roughly a $3.39 to $3.60 per-share discount totaling approximately $100 million in savings across the transaction. The private placement closed June 4, the same day as Alphabet's public offering, with Berkshire having first established its stake in Q3 2025 and describing this as an addition to that position. This single transaction accounts for more than 40% of every dollar of stock Berkshire purchased during the quarter.

Operating earnings rose 16% year-over-year to $12.98 billion, while net earnings—Buffett's preferred metric strips out portfolio volatility—roughly doubled to $25.67 billion. Share buybacks jumped to $4.53 billion from $235 million in Q1, signaling management confidence in intrinsic value at current valuations.

Key Numbers

- Berkshire purchased ~$23.5B of stock against ~$3.7B sold in Q2—the first net buying quarter since Q4 2022

- $10B went to Alphabet via private placement: $351.81 for Class A, $348.20 for Class C shares

- Public offering prices were $355.1982 (Class A) and $351.8018 (Class C), a ~$100M discount for Berkshire

- Operating earnings rose 16% YoY to $12.98B; net earnings doubled to $25.67B

- Cash pile fell from $397.4B (March 31 record) to $365.5B by quarter-end

What to Watch

Berkshire's Q3 filing will be closely watched for whether the pace of equity deployment continues, particularly given the conglomerate's historical preference for maintaining a substantial cash buffer. Any follow-on moves in technology names or shifts in the utility, insurance, and energy positions that anchor the portfolio will merit attention. Buffett, who stepped down as CEO earlier this year, has left his successors with clear directives on capital allocation—the Q2 activity suggests they're moving decisively.
