Monday, November 17, 2025 at 09:00 UTC+01:00 (+0100), United States, Omaha / New York (filing & market context)

News category : Corporate and Sector Events

Regulatory filings and press coverage on 17 November indicated that Berkshire Hathaway had accumulated a sizable position in Alphabet, worth several billion dollars as disclosed in its quarterly 13F. The move was notable because Berkshire historically avoided large technology bets; the addition signals a shift toward exposure to major AI and ad-tech incumbents. Institutional purchases of this scale can influence flows into mega-cap stocks and affect index allocations. Market watchers interpreted the filing as an endorsement of Alphabet’s fundamentals and strategic position in AI, contributing to upward pressure on its shares and influencing sentiment across growth-heavy indices.
