A reactor went 100 feet down a hole. The stock is the story.

What Deep Fission actually proved this week, and what it did not

Deep Fission announced on Wednesday that a commercial drilling crew lowered a full-size prototype reactor canister 100 feet into a borehole and brought it back up. Standard rig, standard crew, no custom equipment.

Wednesday brief

The SMR trade, six months on

The names that ran in spring have split into two groups, and the difference is redacted, not redacted.

Every issue ends with what stays behind the paywall.

Piers Buckworth has spent 24 years inside institutional markets, and he is still in the market every day.

Those years ran across institutional desks in Asia and Europe, where he learned how markets really work.

He built Apex to bring that knowledge to the retail community, and to show that anyone can learn to manage their own money with confidence, in any market condition.

Apex is where he shows the work. The letter is the free version. The community is the whole thing.
