Advanced Micro Devices (AMD) closed the completed November 11 U.S. regular session at $552.90, up 7.32% from $515.21. Separate early November 12 premarket observations put AMD and Broadcom above their own November 11 closes while Nvidia was below its close. These are changeable premarket observations, not completed November 12 daily candles. In the prior after-hours session, Bloomberg reported AMD and Broadcom gaining on bets they could win business from Nvidia. That is an attributed market expectation, not evidence of an actual customer switch or proven cause of a price move.
Broadcom (AVGO) closed the completed November 11 regular session at $345.22, up 3.99%. Its separate early November 12 premarket direction was higher at the frozen observation, but the daily chart below ends November 11.
Nvidia (NVDA) closed the completed November 11 regular session at $173.73. Its separately observed November 12 premarket direction was lower at the source freeze. The daily chart below ends November 11, before that observation.
The completed AMD chart shows its $552.90 close just above the $550.43 50-day simple average and above the $420.05 200-day average. Its November 5 intraday low was $402.10, the lowest since the May 19 intraday low of $393.36. The November 11 close was 37.50% above the November 5 low; that low-to-close rebound is a different window from the older full decline. Those averages are dated chart observations, not predictions or order-book levels.
