Quant paper summaries on backtest overfitting and residual alpha
Most posts summarise quant research papers in a fixed 'this paper is insane' template: strip beta and factor exposure, test out-of-sample, add costs, distrust small samples and smooth equity curves. A second strand covers AI agent architecture (harnesses, loops, approval gates) tied to Grok Bot, GPT-6 Astra and Picsart. Occasional promos for trading tools such as Medusa and magicmarkets.
