I vibe-coded a defensive ETF strategy that uses trend and SPY correlation analysis. I saw this on X and open-sourced it. The original was implemented for a paid platform, which apparently also handles the actual live trading aspect.

* Selects 2-3 ETFs with lowest 26-week SPY correlation from a universe of 7 ETFs.
* Uses simple momentum/trend signals for entry and exit.
* Manages position drift which keeps outperforming positions open for longer.
2015-2025 backtest:
7.4% CAGR | 14% max drawdown | 0.81 Sharpe ratio
Claimed performance:
10.10%% CAGR | 19.61% max drawdown | 0.74 Sharpe ratio
