What is the RS Matrix?

The RS Matrix ranks a whole group of funds, stocks, or indices against each other at once — not by returns, but by which ones are currently outperforming the others on a chart-by-chart basis.

Relative Strength, Not Raw Returns

"Relative Strength" here has a specific meaning: instead of comparing two investments' returns side by side, QuantLogIQ builds a chart of their price ratio — Fund A's price divided by Fund B's price — and reads that ratio chart's own current signal. If the ratio chart is currently in a column of X's, Fund A is judged relatively stronger than Fund B right now.

How the Matrix Works

The RS Matrix takes every investment in a chosen group and compares it against every other one in the group, pair by pair. Each cell in the grid gets one of three labels:

  • BX — the row investment is currently the stronger of the pair (a buy-side signal for the row)
  • OS — the column investment is currently the stronger of the pair (a sell-side signal for the row)
  • ND — not enough overlapping price history to compare this pair

The Ranking

Each investment's total BX count across all its comparisons becomes its score. The investment with the most BX wins is ranked at the top — meaning it is currently outperforming more of the group than anything else in it, right now.

What It's Useful For

Use the RS Matrix when you want a fast read on which fund, stock, or index in a watchlist-sized group currently has the strongest relative momentum — without manually comparing each pair one at a time.
