Backtest any large-cap — 516 to choose from
The whole S&P 500, Nasdaq-100 and Dow as of 2026-10-07 — 516 names across 11 sectors. Pick any one and run well-known strategies on it on demand, free: honest results, costs on, measured against simply buying and holding (most strategies don't beat it). No code, no advice.
Each pick needs enough history, real liquidity and clean data for an honest backtest — if one doesn't, we tell you exactly why. These are unvetted symbols resolved live when you pick one: picking here runs an on-demand backtest even for names we also track — our curated, DOI-cited census and hand-checked catalog stay separate. We never touch your broker or funds — this only backtests the symbol on historical data.

21Backtesting is one stage of preparing to trade, not the finish line. The full discipline runs five: Understand, Test, Stress-test, Forward-test, then Decide — eyes open. Most ideas should wash out in the first three, and every stage is a place to stop, for free — but the rare idea that survives all five is the one worth taking into the market with your eyes open, and finding it before you risk a cent is the whole point.
