Hi Product Hunt — we built Tradune because “how is my portfolio doing?” is usually answered with a dollar gain or a percentage that misses the important comparison: would the same cash, invested on the same dates, have done better in the S&P 500? Tradune reads your buys, sells and dividends, then compares your money-weighted result with a buy-and-hold SPY twin funded on those same dates. You can add holdings manually or from a file; there is no brokerage login. We also built the tools we wanted around that answer: ETF overlap by underlying holdings, concentration and risk views, dividend and factor screens, and SEC Form 4 insider activity. It is free today, with every feature unlocked. It is an educational analytics product, not investment advice. The most useful feedback for us: what is the one portfolio question you still have to answer with a spreadsheet or several separate tools?
