Sharing my risk-adjusted returns YTD. Here are the takeaways:

📈 Outperforming S&P 500 by ~11%
🧠 Low drawdown
⚖️ High risk-adjusted return
🔍 Very little correlation to S&P 500 (strategy is hunting idiosyncratic alpha, not riding the market beta wave)

yfinance's default MultiIndex is a nightmare for multiple stocks

2 tickers = 10 columns
100 tickers = 500 columns 🙄

I prefer a row-based index
- Always 5 columns (OHLCV)
- Easier indicator calculations
- Debuggable without eyestrain
