Nasdaq-100 futures dip as Alphabet shares sell off after earnings report: Live updates

Alphabet shares tumbled after the company reported a disappointing third quarter, dragging Nasdaq-100 futures down 1.4% early Thursday.

The index futures drop was the sharpest move on the board. S&P 500 futures declined 0.5%, while Dow futures rose 0.3%. That split matters: the selling concentrated in the tech-heavy Nasdaq-100 while the blue-chip Dow held a gain.

Investors are digesting the latest round of hyperscaler earnings, and Alphabet's results set the tone for the session. The gap between the Nasdaq-100's 1.4% loss and the S&P 500's 0.5% decline suggests, as interpretation, that Alphabet's weight in growth-heavy indexes amplified its impact, while the Dow's 0.3% gain points to money rotating away from mega-cap tech rather than a broad risk-off move.

The reaction shows how sensitive index-level pricing remains to single hyperscaler reports. A disappointing quarter from one name was enough to move Nasdaq-100 futures by more than a full percentage point before the cash open.
