How it works
  • We compute a sector/SPY ratio for each XL* ETF and normalise it to 100 at the start of the window.
  • The bar value is the most recent % change in that ratio for the selected timeframe.
  • Positive = the sector is outperforming SPY; negative = underperforming.
Trend & Leadership

Sector Spreads vs SPY

Plots normalised sector/SPY ratio lines. Rising = sector leadership. Use this to spot durable rotation, not one-bar noise.
