Alphabet Plummets 12% Amid Intensifying Tech and Semiconductor Sell-Off

Yahoo Finance · 2026-10-29

A sharp 12.6 percent retreat in shares of Alphabet weighed heavily on the broader equities market, dragging major semiconductor and software players such as Micron, Intel, and Marvell deep into negative territory. Contrasting with the widespread tech sector downturn, healthcare equities emerged as a rare bright spot. Notable industry leaders including Eli Lilly, Merck, and Gilead posted solid upward movements, providing a defensive cushion against the broader market volatility.

Alphabet plummeted 12.6%, triggering a broad sell-off across the technology and semiconductor sectors.

Conversely, healthcare stocks such as Eli Lilly and Merck recorded solid gains amidst the tech weakness, acting as defensive plays.

상승 영향

Biotechnology — Amid the tech sell-off, healthcare-related stocks such as Eli Lilly, Merck, and Gilead posted solid gains, absorbing safe-haven and defensive buying demand.

하락 영향

Semiconductors — In the wake of Alphabet's 12.6% plunge, major semiconductor stocks including Micron, Intel, and Marvell declined together, severely worsening market sentiment.
Software — Due to the deep sell-off across the tech sector as a whole, software-related stocks were also hit and recorded significant declines.

DYAX 전담 분석

Alphabet's 12.6% plunge sharply dampened investor sentiment across the technology and semiconductor sectors, leading to simultaneous declines in major stocks like Micron and Intel. This is analyzed as the result of concentrated profit-taking on overvalued technology stocks.

While continued volatility centered on tech stocks could open the door to further downside scenarios, monitoring capital rotation into defensive sectors like healthcare remains crucial. Investors should closely watch whether the Nasdaq index breaks below its support levels and monitor upcoming earnings from major big tech companies.
