Alphabet on pace for worst single-day decline in company history, on track to erase $464B+ market cap (Oct 29)
What happened
Alphabet shares skidded roughly 12% in Thursday trading and were on pace for the worst single-day decline in the company's history. Class A shares traded around $284; a close near those levels would beat the previous record daily decline of 11.6% from March 2020, in Yahoo Finance daily data going back ten years. The company is on track to lose more than $464B in market value in a single session — the second-worst one-day market-cap loss for any U.S. company on record, behind only Nvidia's $593B loss on Jan. 27, 2025. The selloff dragged the Nasdaq composite down 1.2% even as financials and healthcare held up.
