Jumpstart Signal — Free Stock Screener
Sustainable SRI investing, backtested 14 years
Every trading day JSS emails a short list of high-conviction picks with transparent 100-point scoring (Quality + Entry + Sentiment + Sector). 14-year walk-forward backtests show +163pp alpha vs S&P 500, 64% win rate. ESG/SRI filters exclude 10 categories. Honest case studies include both stocks caught early (NVDA at $6, AAPL at $44 in May 2018) AND stocks missed, with losses published. No paywall, no account. Rigor, without the black box.
Hey Product Hunt 👋
I'm Donal, and I built Jumpstart Signal because I kept seeing stock tips with no methodology, or screeners that hid their logic behind $99/month paywalls.
JSS is free, no account. Every trading day, you get a short email with a handful of US stocks that passed a 5-stage filter: price/volume + ESG/SRI exclusions, trend filters, fundamental + technical scoring, then AI-analyzed news sentiment. Every score is broken down (Quality 60 + Entry 20 + Sentiment 10 + Sector 10 = 100) so you can see *why* a stock was flagged.
What I tried to get right:
✅ 14 years of walk-forward backtests (no peeking at future data)
✅ Case studies showing both the stocks we caught (NVDA flagged at $6.08 in May 2018) AND the ones we missed TSLA never got past watchlist tier). Losses published.
✅ ESG/SRI filters across 10 exclusion categories (fossil fuels, weapons, gambling, tobacco, predatory lending, mining, etc.)
✅ Signal weights chosen by data (Mutual Information, Elastic Net, genetic-algorithm optimization), not intuition or tradition
✅ Nothing hidden: published llms.txt, AI-crawler-friendly robots.txt, full scoring methodology at https://jumpstartsignal.com/how-...
Would genuinely love feedback, especially from folks who got burned by paid stock-tip newsletters. What would make you trust a free one?
