Key Takeaway

Adding 5% Bitcoin to this portfolio would have boosted CAGR from 8.3% to 12.7% — but increased max drawdown from -20.6% to -23.5%.

The Sharpe ratio improved from 0.42 to 0.78, meaning the extra return more than compensated for the added risk.

Methodology

Assets: US Stocks = SPY (S&P 500 ETF), Bonds = AGG (iShares Core US Aggregate Bond ETF), Gold = GC=F (gold futures), Bitcoin = BTC-USD. All weekly adjusted closing prices.

Rebalancing: Weights drift between rebalance dates based on actual asset returns. Rebalancing resets to target weights at the specified frequency. “None” is pure buy-and-hold with no rebalancing.

“Without BTC” comparison: The same portfolio with the Bitcoin allocation removed and remaining weights scaled proportionally. E.g., 50/30/10/10 becomes 55.6/33.3/11.1/0.

Limitations: Past performance does not predict future results. This backtest does not account for transaction costs, taxes, or slippage.
