Nearly identical exposure: Both funds are passively managed, market-cap-weighted U.S. large-cap portfolios from Vanguard, and their performance has tracked each other closely across recent market cycles.

Different baskets, shared theme: AIQ targets the broader AI and big-data software and hardware complex, while BOTZ focuses on robotics and industrial automation alongside AI. Concentration contrast: BOTZ's top 10 holdings represent roughly 58% of assets, versus a more evenly spread portfolio in AIQ, giving BOTZ a higher single-stock concentration profile.

AMAT is the industry's broadest supplier of wafer fabrication equipment (WFE), while KLAC leads the more focused, higher-margin process control and inspection niche.
