StockLab — a free, hands-on stock-analysis trainer
StockLab teaches you to analyze companies the way professional investors do — on a universe of eight fictional businesses, with money you can't lose. Every ticker, price and financial statement is generated, so you can practice judgment without risking a cent and without any temptation to treat the output as a tip. Nothing in StockLab is investment advice.
Start on the Dashboard for a market-cap heatmap and factor "snowflakes", then open a company workspace to work through five lenses. The Chart view draws candlesticks with SMA, EMA, Bollinger Bands, RSI, MACD and ATR, each with a formula popover so you learn what the indicator actually measures. The Scorecard runs 30 checks across Value, Quality, Growth, Momentum and Health, and lets you re-weight the factors to match your own style. The DCF builds a two-stage discounted-cash-flow valuation with a WACC from CAPM and a live sensitivity table — the lesson being that fair value is a range, not a number. The Moat & Quality workbench walks you through the five sources of economic moat and Porter's Five Forces, and the Risk Lab turns edge into a position size using Kelly and fixed-fractional rules.
Three tools make StockLab a genuine trainer rather than a calculator. Compare puts companies side by side across price, grade, factor scores, valuation and momentum so you learn relative analysis. The Watchlist collects the names you're studying. And the Fast-Forward backtest is the part most courses skip: record a Buy, Hold or Avoid call, reveal a simulated future, and see the realized return, the drawdown you'd have endured, and whether your thesis played out — then read the one-line lesson on why outcome and process are not the same thing.
The free tier is genuinely useful: four companies, every tool, two-up comparison and the one-year backtest. StockLab Pro unlocks all eight companies, a Custom Company Builder for entering real filings yourself, four-column comparison with CSV export, longer backtest horizons with a calibration scoreboard, a printable analyst report and the quiz certificate.
