Our read on TNUK

ETF.net Research

In short

CMost nuclear funds stop at the uranium miners. TNUK buys the whole chain: the diggers, the reactor designers and builders, and the crews that operate them, anywhere in the world. A December 2025 arrival priced right at the category midpoint.

Stated mandate

The Fund seeks total return by investing in companies across the nuclear energy value chain, including uranium mining and milling, reactor design and construction, and nuclear reactor operation and maintenance.

Why people hold it

  • Covers the full nuclear value chain: uranium mining and milling, reactor design and construction, and reactor operation and maintenance, not just the fuel end.
  • The 0.75% expense ratio sits exactly at the median for uranium and nuclear funds, and under Range's NUKZ at 0.85%.
  • Global by mandate, which matters when much of the reactor-building and utility side of the industry sits outside the US.
  • Plain equity fund in a standard 1940 Act ETF wrapper. No leverage, no swaps, no outcome period to track.

Worth knowing

  • Launched in December 2025, so there is no long track record, and it is a small fund next to category veterans like URA and NLR.
  • Trades lightly compared with the category's heavyweights, so spreads can be wide and limit orders do real work here.
  • The mandate is total return, and the fund has not been making distributions. Income is not the job.
