SOXX tracks the ICE Semiconductor Index, which holds approximately 30 semiconductor companies with a modified equal-weight methodology that prevents excessive concentration in any single name — a key differentiator from SMH, which is more top-heavy toward NVIDIA and TSMC. This broader balance across chip designers (fabless), integrated device manufacturers, foundries and equipment makers provides somewhat more diversified sector exposure. Major holdings include NVIDIA, Broadcom, Qualcomm, Texas Instruments, AMD, Applied Materials and Lam Research — spanning the full semiconductor value chain. The 0.34% expense ratio is slightly lower than SMH's 0.35%. Both SOXX and SMH will perform similarly over time since they track closely related indexes, but the weighting differences mean performance can diverge in periods where the very largest names are either dramatically outperforming or underperforming the rest of the sector. For investors choosing between SOXX and SMH, the decision hinges on whether they want maximum-weight concentration in the largest names (SMH) or a more evenly distributed semiconductor sector exposure (SOXX). Both are excellent liquid vehicles for the same fundamental theme: exposure to the technology infrastructure enabling AI, cloud computing and digital transformation.
