A quantitative trading firm. We trade options and futures on the S&P 500.
Trading live since April 2026. Performance is shared privately with qualified investors.
What we do.
Grow our investors' capital. Put part of the profits to work beyond the firm.
That is why the firm exists. We trade options and futures on the S&P 500. Every position has a fixed maximum loss, and we are in and out within the same trading day. Our own software finds the trades and places them.
The system earns from hedging pressure inside the options market. That pressure appears whether stocks rise or fall, so the fund's results move on their own path. When the market drops, the pressure is still there, and the system still trades it.
How the system works.
Large market makers stand between buyers and sellers in the options market. As positions and prices change, they are required to buy or sell the index to stay balanced. That forced buying and selling can be measured, and it is what the system trades.
Big options positions build up. Market makers must rebalance, and forced buying or selling shows up in the index.
Our models separate that forced buying and selling from ordinary noise and score it in real time.
When the flow is clear, the system trades it, with size and maximum loss set before entry. When it is not, the system passes. Either way, the book closes flat by the end of the day.

Common questions.
What does 5 Stones trade?
Options and futures on the S&P 500, some of the deepest and most liquid markets in the world. Every position has a fixed maximum loss. Positions open and close within the trading day, and nothing is held overnight.
How does the system decide when to trade?
As options positions change, large market makers must buy or sell the index to stay hedged. The system's proprietary models identify that forced flow and separate it from ordinary market noise. The system trades only when the flow is clear and separate signals agree. On other days it does not trade, and capital stays in reserve.
How is risk controlled?
Three ways. Every position has a known maximum loss before it opens. A hard daily limit caps how much capital can be at risk in any single session. And every position closes before the day ends, so the fund holds only cash overnight. All trading involves substantial risk, including loss of principal.
Where can I see performance?
We share performance privately with qualified prospective investors as part of the offering documents, under confidentiality. Private funds are not allowed to advertise performance to the public, so we share it directly instead. Request an introduction and we will walk you through it.
Who can invest, and what is the process?
Interests are offered privately to accredited investors. The process starts with a conversation with the principals, followed by offering documents under confidentiality, then subscription and funding. Qualified inquiries receive a response within two business days. The General Partner reserves the right to accept or refuse any prospective investor.
