## Questions

### Does Portman Square Capital manage external client capital?

No. Portman Square Capital operates as a proprietary trading firm, deploying exclusively partner capital. There is no external fundraising, no fund-of-funds relationships, and no institutional or individual client capital at risk in the firm's strategies.

### What strategies does Portman Square Capital run?

The firm blends systematic and quantitative approaches with discretionary macro and relative-value strategies. Execution is concentrated in liquid, exchange-traded instruments across equity derivatives, fixed income, and foreign exchange markets in developed economies.

### Where does the name Portman Square Capital come from?

The firm's registered address sits near Portman Square in central London — an area historically associated with quantitative finance and alternative investment managers in the city. The name reflects the geography of its founding.

### How does Portman Square Capital source and retain talent?

The firm competes in the same London talent market as larger proprietary trading firms, targeting quantitative researchers, traders, and technologists. Its pure partner-capital model can be a differentiator in recruitment — all risk-taking flows directly to the individuals and teams generating returns, without external management fees or client mandates filtering the economics.
