Our read on each fund

ETF.net Research

LUMAFKraneShares Photonic and Optical ETF

WTAIAWisdomTree Artificial Intelligence and Innovation Fund

In short

LUMA No data

WTAI Most AI ETFs are a repackaged bet on the same few mega caps. WTAI spreads roughly 90 global names across the whole stack (software, chips, the hardware underneath) at close-to-equal weights, for 0.45% a year.

Stated mandate

LUMA No data

WTAI The fund seeks to track, before fees and expenses, the price and yield performance of the WisdomTree Artificial Intelligence & Innovation Index, whose constituents are companies primarily involved in the AI and innovation investment theme.

Why people hold it

LUMA No data

  • WTAI Charges 0.45% a year, below the median fee in the AI thematic crowd. In a theme this packed, cost is the part you actually control.
  • Weights land close to equal across roughly 90 stocks, so no single mega cap runs the portfolio the way it does in cap-weighted AI funds.wisdomtree.com
  • The index reaches across AI software, semiconductors and the other hardware AI runs on, and it can hold listings outside the US, not just a Nasdaq tech slice.wisdomtree.com
  • One of the stronger builds in a crowded AI cohort: broad rules-based portfolio, low fee, no structural quirks in the wrapper.

Worth knowing

LUMA No data

  • WTAI Still one theme. Tech-heavy and prone to bigger swings than a broad-market fund. Owning 90 names dilutes single-stock risk, not AI risk.wisdomtree.com
  • Near-equal weighting cuts both ways: when one giant is carrying the theme, spread-out weights keep this fund from leaning into it.wisdomtree.com
  • The roster resets at scheduled rebalances rather than continuously, so index changes arrive in batches and bring turnover with them.wisdomtree.com
