Large-cap technology stocks fell Thursday, dragging Nasdaq futures lower.
Dow futures declined by nearly 100 points as worries about the effects of rate hikes and the removal of stimulus by the Federal Reserve hit the broader market.
Shares of Facebook, Amazon, Apple, Neftlix, Google-parent Alphabet and Tesla also were lower before the opening bell. Nasdaq futures pointed to a sharply lower open for the tech-heavy index, falling nearly 60 points.
Analysts at Canaccord Genuity downgraded Alphabet's stock to hold from buy, noting they believe the ad load increases on mobile search and YouTube from the past two years will "be hard to repeat."
