Our read on DAT
CMost AI funds hand you the same megacaps in a new wrapper. DAT screens for companies that earn at least 75% of revenue from data plumbing, caps any name at 4.5%, and buys globally. The refiners, not the giants.
The fund invests in a global portfolio of companies involved in analytics, software, hardware, and computing infrastructure that manage and extract information from large structured and unstructured datasets.
Why people hold it
- Hard purity screen: a company must draw at least 75% of revenue from nine data-related sub-industries to qualify. No side-door megacaps riding in on a rounding error.w.proshares.com
- Every position is capped at 4.5% and the index is rebuilt semiannually, so roughly 30 names split the pie instead of one giant swallowing it.w.proshares.com
- 0.58% expense ratio undercuts the typical fund in its AI-infrastructure peer group, and sits below XDAT's larger rivals on the shelf without the megacap overlap.
- Casts a global net: US, developed and emerging market names all eligible. Launched in 2021, before the AI theme became a launch-pad stampede.w.proshares.com
Worth knowing
- Non-diversified and sector-concentrated by design. ProShares says narrowly focused investments typically show higher volatility, and about 30 holdings means single names matter.proshares.com
- A small, thinly traded fund. Spreads can widen and large orders move the price more than they would in a heavyweight AI ETF.
- ProShares reports the fund has made no distributions, so the return story is share price, not income. Emerging market holdings add liquidity and currency risk.proshares.com
