Defensive portfolio vs. the S&P 500
Equal-weight WM, BRK.B, KO, JNJ, PG. Daily data, April 2021 to April 2026.
Defensive portfolio vs. S&P 500 (SPY), April 2021 to April 2026
| Metric |
Portfolio | S&P 500 (SPY) |
| Annual return (CAGR) | 11.49% | 11.75% |
| Max drawdown smaller loss is better | −15.7% | −24.5% |
| Volatility | 12.5% | 17.1% |
| Sharpe ratio higher is better | 0.58 | 0.44 |
Nearly the same annual return as the S&P 500, with a smaller fall at the worst point and about 27% less volatility.
Backtest: the five stocks were chosen in 2026 with hindsight, so this describes one five-year window, not a forecast.
