Berkshire Hathaway Class B shares declined 1.74% to $487.73 on October 16, 2025, underperforming the broader market's 0.89% decline. A technical analysis report highlighted a short trade opportunity, noting that BRK.B is trading within a key resistance zone between $492.98 and $505.85, with bearish indicators including a return on invested capital (ROIC) below the weighted average cost of capital (WACC) and shrinking profit margins. The stock moved lower while the S&P 500 pushed higher earlier in the session, which was characterized as a significant bearish signal. Meanwhile, recent 13F filings revealed that Warren Buffett's team purchased $1.33 billion worth of Lennar, Constellation Brands, and Chevron in the second quarter, though Buffett is reportedly set to retire at the end of 2025. The current price of $487.73 sits near the midpoint of its 52-week range of $406.11 to $542.07, with the stock trading at a forward P/E of 23.28.
