How it works

Use the search bar at the top of the simulator to find any publicly traded stock, ETF, cryptocurrency, or bond. Type a ticker (AAPL, SPY, BTC-USD) or a company name (Microsoft, Vanguard Total World). The dropdown shows live results across global exchanges \u2014 NYSE, Nasdaq, LSE, XETRA, Euronext, JPX, NSE, ASX, JSE, and more.

Click an asset to add it to your portfolio. You can mix any combination: 80% US equities, 15% European bonds, 5% crypto \u2014 whatever you want to test.

Free portfolios hold up to 4 assets. Pro portfolios are unlimited. If you just want to start fast, click one of the preset buttons (Tech Heavy, Balanced, Crypto Mix) and tweak from there.

Each asset gets a weight \u2014 the percentage of the initial investment allocated to it. The weights must add up to 100%. Drag the sliders or type exact numbers. Click "Rebalance equally" to split the portfolio evenly across all assets in one tap.

Set the initial investment amount and currency at the top of the panel. The simulation assumes you bought at the start of the period and held \u2014 a "buy and hold" strategy. For more sophisticated scenarios with multiple lump sums or regular contributions, switch to Advanced mode (free for one plan; Pro for unlimited).

The chart shows portfolio value over time. The stats bar above breaks down the results: total return, CAGR (compound annual growth rate), max drawdown (the worst peak-to-trough fall), volatility, and Sharpe ratio (return per unit of risk).

Switch the date range with the tabs (1Y, 3Y, 5Y, 10Y, MAX). Switch between Past mode (real historical data) and Future mode (forward projections using your assumed returns and volatility). Compare against the S&P 500 benchmark with one toggle.

What does CAGR mean? It is the smoothed annual return rate that would have taken your starting amount to your ending amount. A 10% CAGR means the portfolio averaged 10% per year, compounded. Read our full explainer: CAGR Explained.
