Equal-weight vs Cap-weight Ratio maintains the equal-weight vs cap-weight ratio as a regime-aware series rather than a manual symbol division. The equal-weight leg is divided by the cap-weight leg and rebased to 100 at the anchor, so the pane reads as relative performance since that date. A long moving average separates durable shifts from noise: the ratio above it is labeled broad participation, below it narrow leadership.

How to Trade the Equal-weight vs Cap-weight Ratio?

  • Broadening / Narrowing Shift: crossings of the long moving average mark durable turns in participation; both directions are alerted.
  • Context events: a fresh benchmark high with the ratio below its average flags an advance carried by the largest names; the mirror flags the typical member holding firm through benchmark lows.
  • Since-anchor read: distance from the dotted 100 baseline is the equal-weight leg's cumulative result versus the cap-weight leg.

It reads alongside the library's participation and breadth gauges.

Equal-weight vs Cap-weight Ratio Settings

  • Equal-Weight Leg (default AMEX:RSP) and Cap-Weight Leg (default AMEX:SPY): pair fund with fund or index with index so the ratio isolates weighting.
  • Timeframe (default: chart timeframe) and Dividend-Adjusted Legs (default on): how both legs are requested.
  • Rebase To 100 (default on) with Anchor (default First available bar) and Anchor Date (default 1 Jan 2020): the normalization; off plots the raw quotient.
  • Type (default SMA) and Length (default 200): the regime-defining moving average.
  • Benchmark Swing Lookback (default 50): window flagging fresh benchmark highs and lows.
  • Highlight Context Events (default off): optional background tints; alerts fire regardless.
  • Display: Show Dashboard, Show Moving Average, Gradient Fill and Anchor Baseline (all on).
