What it shows

Sector relative strength divides a sector index (for example the technology sector) by the broad market index. A rising line means the sector is beating the market.

Rotation is the idea that leadership moves from sector to sector over time. We show which ones lead and lag over 3 months.

How we find it

The same code that draws it on your chart follows these steps, with the same result every time.

  1. Pick a sector index and the broad market index.
  2. Ratio = sector ÷ market.
  3. Compute the 63-bar change in the ratio.
  4. Rank sectors by it.

Starting values: Window 63 bars. These are proposed and will be tuned on real price data before launch.

How to read it

  • The panel shows the sector against the market.

Why compare to the market?

To remove the effect of a rising or falling market.
