Buffett Successor Greg Abel Sells Nucor Stake, Pivots Berkshire to AI

Key Facts

In a move reflecting a strategic shift in Berkshire Hathaway's portfolio management under Greg Abel, Warren Buffett's successor has significantly reduced the firm's stake in steelmaker Nucor. According to reports, the transaction involved selling over 50% of the company's holding in NUE, as Abel seeks to rebalance the portfolio away from traditional industrial investments that performed strongly in 2025. This action comes as investment decision-making authority transitions to the firm's new leadership.

Parallel to the exit from the steel sector, Berkshire Hathaway increased its position in an AI-related stock that billionaire investor Bill Ackman recently exited. This pivot highlights Abel's intent to capture growth opportunities within the technology and artificial intelligence sectors, signaling a departure from the firm's historical concentration. Per market data, Nucor (NUE) shares closed at $264.19 on August 18, 2026, after reaching a session high of $271.72.

Investors are currently watching for NUE to maintain support near the $263.23 level, which was the intraday low recorded on August 18, 2026. With no immediate catalysts in the upcoming economic calendar specifically targeting the steel industry, market focus remains on identifying the specific AI instrument added to Berkshire's holdings. This transition serves as a significant indicator for retail traders regarding capital flow trends in major institutional portfolios.
