Chip stocks hot again amid AI capex confidence

Semiconductor stocks are trading at elevated conviction levels, with NVIDIA, AMD, Broadcom, and related names capturing outsized retail attention and trading volume. The SOXX semiconductor index has gained over 72% year-to-date and is near 52-week highs. On Wall Street Bets, semis dominate the trending tickers list, with Micron Technology ranking number one in 24-hour engagement, followed by NVIDIA and AMD in the top 11.

The narrative driving this renewed enthusiasm is confidence in the durability of AI capital expenditure. Fund managers and traders see a path to sustained semiconductor demand as enterprise and hyperscaler capex cycles extend well into 2026 and beyond. Western Digital has outperformed NVIDIA by 3x over the past month, suggesting that storage and memory products tied to AI data centers are capturing some of the capex allocation. Broadcom, which supplies infrastructure semiconductors, has also been in focus.
