Broadcom (NASDAQ: AVGO) finds itself at the center of multiple storylines today: a world‑first quantum‑safe data‑center networking launch, an unverified ransomware breach claim, fresh institutional buying, and ongoing volatility across AI chip stocks ahead of its next earnings report.

As of late afternoon on Friday, November 21, Broadcom shares are trading around $335–$340, down roughly 3% intraday, after ranging between about $332 and $351 on heavy volume. That leaves the stock below its recent close of $346.82 on Thursday—which itself represented a 2.1% slide and underperformance versus the broader market. [1]

Yet despite the pullback, AVGO remains one of 2025’s standout AI infrastructure names, having dramatically outperformed the S&P 500 over the past year and riding a powerful structural story in custom AI silicon and high‑margin software. [2]

Below is a breakdown of what’s moving Broadcom stock today and what investors are watching next.
