https://github.com/zonination/investing ↗What this repo does
An R analysis and visualization of historical S&P 500 real total returns by holding period, showing distributions and probabilities of gains/losses over time. It uses Shiller-derived data (last updated in 2016) to illustrate long-term buy-and-hold outcomes with static plots.
Why this was rejected
- ✕Well-served market: PortfolioVisualizer, Morningstar, and Nitrogen (Riskalyze) already provide similar or richer return-distribution education and planning tools.
- ✕Repo is a 2016 R script with static data and no API; turning it into a sellable SaaS would require a full rewrite plus live data pipelines and interactive UX beyond a 3‑month solo scope for differentiation.

How it could be fixed
Build a web app with automated daily/weekly data ingestion (FRED/Shiller, paid market APIs), expand beyond S&P 500 to multi-asset portfolios, deliver interactive holding-period and DCA simulators, exportable/branded reports, embeddable widgets, compliance logging for RIAs, and lead-capture pages; position specifically for small RIAs without enterprise stacks.
Alternative uses
- →Educational content and visuals for personal finance blogs and newsletters.
