A proprietary trading firm operating across equities and derivatives. We deploy our own capital with discipline — engineering edge from structure, not sentiment.
We approach markets as systems of competing objectives — each participant with their own constraints, horizons, and incentives.
Founded in 2019, Limestone is a proprietary trading firm operating across equities and listed derivatives. Our work is to find where those forces create persistent, exploitable structure — then deploy our own capital against it with a focus on risk-adjusted returns and operational rigor.
Systematic, data-driven inquiry across market structure and price dynamics.
Low-latency, efficient execution across equities and listed derivatives.
Disciplined portfolio construction and real-time risk monitoring.
A small, deliberate group. We are researchers first — drawn to hard problems, skeptical of consensus, precise in our methods.
Alpha here is earned through intellectual honesty, not convention. Every position is grounded in a quantifiable thesis with defined entry, exit, and risk parameters — the product of genuine inquiry, not intuition dressed up as process.
We look for real intellectual curiosity — people given real problems, and real ownership, from day one.
We move fast, hand real responsibility from day one, and reward ownership. The structure is flat, the meritocracy is real, and the problems are genuinely interesting.
