Disclaimer: All figures shown are estimates based on historical averages and simplified calculations. They do not account for correlations between asset classes, taxes, fees, inflation, or future market conditions. Past performance does not guarantee future results. This tool is for educational purposes only and should not be considered financial advice.
Start with a preset, then change the weights and watch the estimated return, volatility, and worst-case drawdown move together. Loading up on one high-return, high-volatility asset pushes the expected return up but also widens the potential drop. Mixing in steadier assets usually softens the swings. That tension between return and risk is what asset allocation is really about.
The numbers use simplified historical averages and assume no correlation between assets, so real portfolios will behave differently. This is a learning sandbox, not a recommendation of any particular mix.
You add asset classes (like US stocks, bonds, or gold) and assign each a percentage weight. The tool combines the historical average return, volatility, and drawdown of each asset, weighted by your allocation, to show estimated portfolio-level numbers. You can also start from a preset mix and edit it.
Asset allocation is how you split your money across different types of investments. Because asset classes behave differently, the mix you choose tends to shape both the expected return and how bumpy the ride is. This sandbox lets you feel those trade-offs without risking real money.
The Sharpe ratio is a rough measure of return earned per unit of risk; max drawdown estimates the worst peak-to-trough drop. Both are shown as simplified, educational estimates to compare hypothetical mixes, not as quality ratings or recommendations.
They are deliberately simplified. The tool assumes no correlation between assets, which understates real-world risk, and ignores taxes, fees, and inflation. It is built to teach the idea of diversification, not to forecast performance.
