Overall thesis

In one line: the nuclear fuel trade has worked and still has room, but the next leg is demand-led: Western reactors actually getting built. So own the tech-agnostic suppliers of long-lead parts (Doosan, BWXT) and Westinghouse via Cameco, and on the fuel side go to Canada, where the Athabasca juniors are cheaper than Cameco into a consolidation wave.

The product

Grounded in his own description on 2026-SEP-16 (00:09–04:51).

What it is: Ocean Wall is a London firm founded ~7 years ago that publishes research "on all aspects of the nuclear fuel cycle." Examples are the report "From Blueprint to Fleet: Mapping the Nuclear Trade" and a stand-alone BWXT report that Finegold offers to share. With partners 5T in Zurich it also runs a dedicated 5T Nuclear Fund that carries "quite a large supply chain exposure." It is also putting together development capital for a UK SMR project.
