GRAYBOOK CAPITAL

About

The trading firm of the Graybook group.

Graybook Capital trades the group’s own capital. We sit beside the companies that build our infrastructure, our models and our platform, so every idea we have can be tested, built and traded under one roof.

How we work.

Evidence over opinion

Every idea is a hypothesis until the data says otherwise. Seniority doesn’t win an argument; a better test does.

Own it end to end

The people who design a strategy, build its systems and set its limits sit together and share the result.

Risk first, always

We would rather miss a trade than take one we don’t understand. Limits are built into the code, not left to judgment in the moment.
