How does portfolio risk change when combining different ETFs?
Available evidence
Reference universe: SPY, QQQ, IEF and GLD; illustrative weights of 40%, 20%, 25% and 15%.
Method
Daily returns, monthly rebalancing, volatility, drawdown, 95% historical VaR/CVaR and a 252-observation backtest.
What this demonstrates
The project compares risk measures and allocation scenarios. No fixed return figures are published because the app depends on an external, unfrozen CSV.
Interpretation limits
Historical and in-sample results; assumed 0% risk-free rate, assumed costs and an external data dependency. Not investment advice.
