Signal
On June 3, 2026, the iShares Semiconductor ETF (ticker SOXX) recorded an ETF holdings change event. The fund lists on the NASDAQ Global Market, manages $39.84 billion in assets, has a daily average trading volume of $4.41 billion, posted trading volume 1.47 times its average on the event date, and saw a 5.79% one-day price gain. Launched and first traded on July 10, 2001, SOXX currently holds 30 securities, with a top-5 holdings concentration of 42.07% and top-10 holdings concentration of 62.73%.
Portfolio Read
Two individual stock weight adjustments were made during this event: Marvell Technology (MRVL) saw its weight rise from 6.18% to 8.26%, a 2.08 percentage point increase, while Intel Corporation (INTC) had its weight drop from 6.53% to 5.49%, a 1.04 percentage point decrease. The fund’s current top-5 holdings are Micron Technology (MU, 11.97%), Advanced Micro Devices (AMD, 9.01%), Marvell Technology (MRVL, 8.26%), Broadcom (AVGO, 6.99%), and NVIDIA (NVDA, 5.83%), with exposure to high-demand semiconductor themes including HBM memory, AI accelerators, and AI networking silicon.
Active vs Passive Read
The fund’s strategy is classified as passively inferred, meaning it is assumed to track a designated index based on its product name and issuer background, with no official explicit statement confirming active or passive management.
Why It Matters
As a large semiconductor-themed ETF with nearly $40 billion in assets under management, SOXX’s holding adjustments directly shift investor exposure to the global semiconductor sector. The targeted weight changes to AI-linked semiconductor stocks align with current artificial intelligence investment themes, and the fund’s concentrated holdings structure means shifts to individual component weights will have a measurable impact on the fund’s overall performance.
What to Watch Next
Investors should monitor future official holdings disclosures for SOXX to confirm whether the adjusted MRVL and INTC weights are maintained, as well as any additional holding changes that may alter the fund’s AI semiconductor exposure profile.
