RSraw — the weighted twelve-month return

What it measures

RSraw is a weighted blend of a share's returns over four windows — roughly the last three, six, nine and twelve months (63, 126, 189 and 252 sessions) — with the most recent quarter weighted double:

RSraw = 0.4 × ROC(63) + 0.2 × ROC(126) + 0.2 × ROC(189) + 0.2 × ROC(252)

where ROC(n) is the percentage change in the price over n sessions. The Technical page shows it for the share and for its benchmark side by side.

Why it is on the page

It is the raw score behind the 1–99 "relative strength ratings" some investment publishers print, where every share in a large universe is ranked by it. The product shows the raw blend for the share and the benchmark, so the two can be compared directly.

Thresholds, their source and the population they were fitted on

RSraw has no zones. A rating from 1 to 99 needs thousands of shares to rank against; the product's catalogue is far smaller, so the page states the rank as unavailable — requires a ranked universe rather than ranking against too few shares to mean anything.

  • Source: the blend widely reproduced from William O'Neil's relative-strength rating; the publisher's own smoothing is not public.
  • Fitted on: no population — a measurement.
  • Evidence grade: practitioner convention.

A worked example

An illustration, not a stored figure: returns of +8% over three months, +12% over six, +15% over nine and +20% over twelve give RSraw = 0.4 × 8 + 0.2 × 12 + 0.2 × 15 + 0.2 × 20 = 12.6. Beside a benchmark at 9.0, the share's recent returns have run ahead of the market's.

What “No verdict” means here

RSraw carries no verdict and no vote. It reads insufficient data until 252 daily bars are stored for the share (and for the benchmark, on the benchmark's side).

What the verdict is and is not

The figure describes past returns, weighted towards the recent ones. It is not a rank, not a forecast, and not an instruction to trade the shares.
