I hire physicists, not traders. Markets are a natural phenomenon. You study them with science, not gut feelings.

When our edge diminished, I gave back half the money. Most hedge fund managers would never do that. That's why I did it.

Risk management matters more than return generation. If you control the downside, the upside takes care of itself.

Financial markets contain real, exploitable patterns. But finding them requires rigor, not narratives and opinions.

I donated £100 million to Cambridge because the future depends on science, not on making hedge fund managers richer.
