Broadcom shares plunge 4.48% as sector pressures and macroeconomic uncertainties drive pre-market selloff

Broadcom shares fell 4.477% in pre-market trading on December 18, 2025, signaling a sharp decline ahead of the opening bell. The selloff intensified as investors recalibrated expectations amid shifting sector dynamics and macroeconomic uncertainties.

Analysts noted the drop could reflect broader tech sector pressures, with markets pricing in potential regulatory headwinds for semiconductor leaders.

The move follows recent volatility across growth stocks, as investors balanced near-term earnings risks against long-term growth narratives in AI-driven infrastructure demand.

While no company-specific catalysts were immediately identified, the decline aligns with a risk-off sentiment observed across growth equities. Traders are now monitoring key earnings reports and central bank signals for directional clues as the year-end trading window approaches.
