Backtest
Pick a stock, crypto, commodity or futures contract, a date and an amount. This shows what that money would be worth today, using the actual price history — nothing here is a prediction about what happens next.
Want to test the screener itself, not one stock? Backtest buying the healthiest companies.
This app fetches at most ten years of daily prices, so the test starts from rather than the date you chose. AAPL may well have traded before then.
AAPL split its shares 4:1 on . Prices and share counts here are adjusted for that, so every figure is on today's footing and comparable across the whole period — which means they will not match the headline price you remember from before the split. Your money was unaffected either way: a split hands you more shares at a proportionally lower price.

Annualised — the steady yearly rate that would produce the same result.
Dividends, if any, were reinvested into more shares rather than paid out as cash.

Each row is the same lump sum invested that far back and held to today — not a strategy, just a different starting date. A row marked “from … only” is shorter than its label because the price history does not reach back that far.
Want to see this against the market, or against anything else? Compare AAPL with SPY — that page charts any set of symbols side by side, which is the job it does properly.

Trading strategies
Run mean reversion, RSI dip buying, the golden cross, a 200-day trend rule and an intraday opening-range breakout over the same stock — each against simply buying and holding it.
Four things need a free account: the screener backtest, the trade journal, the trading strategies, and the moving averages drawn over a result. Everything else works signed out — company pages, the screener, comparisons, charts, crypto and commodities, and working out what an investment would have been worth.
Educational only, not investment advice. This uses real historical prices and, where available, real dividend payments — but it assumes a lump sum invested on one day and held without ever selling, which is rarely how anyone actually invests. No fees, spreads or taxes are modelled, and no correction is made for surviving to be listed today — a company that failed along the way would not appear here to be picked at all.
