US big tech stocks dropped in premarket trading on Monday, signaling risk aversion ahead of a slew of economic data this week even as bets for a December Federal Reserve interest-rate cut remain firm.

TSMC fell 2%; Palantir, Meta, Tesla, Nvidia, AMD, and Broadcom fell about 1%; Alphabet and Amazon fell 0.8%; Apple fell 0.7%.

The week ahead is set to offer a crucial snapshot of US economic momentum as policymakers weigh the trajectory of interest rates heading into 2026. With inflation and consumer demand under scrutiny, data is likely to shape expectations for whether the Fed continues its rate-cutting cycle. Traders are also bracing for potential shifts in central bank leadership with White House economic adviser Kevin Hassett signaling markets were ready for the announcement of a new Fed chair.
