Tech Stocks Get Hammered in Worst Week Since April 2025

The Nasdaq posted its ugliest weekly decline in nearly a year as geopolitical turmoil and legal woes crushed Big Tech.

It was a brutal week for tech investors. The Nasdaq recorded its worst weekly plunge since April 2025, dragged down by escalating tensions from the Iran conflict and a string of courtroom losses for Meta.

Meta took the hardest hit, cratering 11% over the week. Alphabet wasn't far behind, shedding roughly 9%. Microsoft dropped around 7%.

The selloff hit tech harder than the broader market. Geopolitical instability spooked investors already on edge, and Meta's legal defeats added fuel to the fire. The combination proved toxic for the sector's biggest names.

No single catalyst drove the rout — it was the one-two punch of war fears and regulatory headwinds landing simultaneously. For a sector that had been riding high, this week served as a sharp reminder that gravity still exists.
