Berkshire Hathaway shares hit new highs despite Alphabet's big losses amid AI concerns.

Berkshire Hathaway's Class A and B shares reached new all-time highs this week, closing October with strong gains of 8.9%, outperforming the S&P 500 and Nasdaq. However, Berkshire's significant investment in Alphabet suffered a sharp decline after Alphabet reported disappointing earnings and high AI-related costs, causing its market value to drop by about $500 billion. Berkshire also trimmed its stake in DaVita to maintain a set ownership percentage. Overall, Berkshire is benefiting from a market rotation away from high-flying tech stocks toward more stable investments.

Berkshire Hathaway's Class B shares have a market cap of $1.16 trillion and show steady investor confidence with an 86% buy order activity on Pluang as of Oct 31, 2026 19:41 WIB. Despite the recent volatility in Alphabet's stock, which trades at $279.84 with a 1-day decline of 1.40%, Berkshire maintains its strong position. DaVita shares are down 2.93% at $187.65, reflecting some sell pressure with 71% sell orders on Pluang. This data highlights the ongoing rotation in investor preferences between stable and volatile assets.
