How SMH differs from SOXX
SMH and SOXX both track semiconductors but with different weighting schemes. SMH is more concentrated in its top holdings — NVDA and TSM often represent 15-20% of the fund — while SOXX is more equally weighted across the semiconductor value chain.
That concentration means SMH moves more like NVDA on most days, while SOXX gives a broader read on the entire chip sector. The page should help traders choose between them based on whether they want AI-weighted exposure (SMH) or broad semiconductor exposure (SOXX).
- SMH has heavier NVDA and TSM weighting — it moves more with AI demand.
- SOXX is more equally weighted — it captures the full semiconductor cycle better.
- Use both together: if SMH leads SOXX, AI spending is driving chips. If SOXX leads, the cycle is broader.
