Semiconductor stocks rally on retail appetite and AI demand

The semiconductor complex is riding dual tailwinds: relentless institutional AI capex cycles and explosive retail participation that has rewired equity trading flows. SOXX, the semiconductor index, has gained 72.88% year-to-date and sits near 52-week highs. Retail activity on Wall Street Bets shows seven of the top eleven trending tickers are semiconductor and storage names, with Micron ranking number one, NVIDIA at number eight and AMD at number nine. NVIDIA call-to-put ratios reached 3.03, an extreme call bias that signals retail traders are pricing in further upside and viewing pullbacks as buyable dips rather than reversals.

The AI capex narrative remains the primary driver. American Electric Power announced a 2.6 billion dollar share sale, explicitly citing AI-driven booming demand for electricity as the rationale.

Multiple sources highlight that AI infrastructure buildout is not slowing but accelerating, keeping capex budgets elevated at major cloud and chip manufacturers.

Retail positioning is proving sticky. The CPI print on May 12 sparked a broader market pullback, but chip stocks showed relative resilience.

Western Digital outperformed NVIDIA by 3x over the past month, raising questions about whether peak NVIDIA gains have passed, but the broader semiconductor sector remains bid on the thesis that AI infrastructure spending is multi-year and structural, not cyclical.
