Evidence before conviction.
A private, paper-only research beta for investigating US equity strategies with historical data, modeled trading costs and checks for luck and overfitting.
Explore the private betagewahr (German): aware of something, having become aware of it, as in einer Sache gewahr werden.
What we do
Point-in-time testing
Our research uses historical S&P 500 membership, including former constituents, to reduce survivorship bias. Data limitations still matter.
Costs and luck, counted
Modeled costs and multiple-testing checks help question results that may be explained by luck. Historical tests cannot establish future performance.
Bring, build or match
We are developing ways to bring your own rules, build strategies from indicators, and explore research that fits your goals. These workflows are still in development.
For brokers and investors
The private beta is designed to help brokers and individual investors inspect evidence and record paper-only research, before considering real-world decisions.
Gewahr is in a private research beta. It provides research and historical analysis only, with simulated paper results and no real-money orders. It is not investment advice, does not execute trades, and past results do not guarantee future returns.
