Quantum computing is getting attention as the next step after AI, but picking individual stocks is risky right now. ETFs are a way to reduce that risk without betting on a single company. Defiance Quantum ETF (QTUM) is the established option. It has been around since 2018, holds 84 stocks, and has over $3 billion in assets. The expense ratio is 0.40%. WisdomTree Quantum Computing ETF (WQTM) is a newer, smaller fund. It is more concentrated with 37 holdings and a 0.45% expense ratio. It holds companies like Alphabet and Nvidia in its top 10, which differs from QTUM's structure. The general view is that these are buy-and-hold plays for the next decade while the technology matures.
