Profile

Hey HN, JSS(JumpstartSignal) is a free, ESG-filtered daily stock screener. I built it after some really badly-timed quantum computing stock buys, so I felt I needed to learn more about systematic, longer-horizon approaches and the underlying technicals instead of chasing themes. Three things about it that might be of interest:1. Methodology is fully documented at https://jumpstartsignal.com/how-it-works/ 5-stage pipeline, 54 signals tested individually plus 1,836 combinations evaluated, walk-forward validation across 25 hold periods. Nothing hand-tuned to a single backtest window.2. Many wins, misses, and losses are published as case studies e.g. https://jumpstartsignal.com/case-studies/nvda

Its activity falls under show hn launch; the profile below is assembled from public directory data.

The company is listed at the Show HN launch stage of development.
