# Trading with Concave Price Impact and Impact Decay - Theory and Evidence

The research examines statistical arbitrage issues, taking into account the nonlinear and temporary price impact of metaorders, and shows that simple trading rules can be established even with nonparametric alpha and liquidity signals.
