Relative RotationBeta

Each point is one security against NIFTY 50: horizontal is relative strength, vertical is the momentum of that relative strength, both centred on 100. The trail is the last few periods, so direction matters as much as position — the usual rotation runs clockwise, Leading → Weakening → Lagging → Improving → Leading.

This is an approximation, not the licensed JdK formula. RS-Ratio and RS-Momentum are proprietary to RRG Research; this uses the published approximation — smoothed relative strength, z-scored onto a 100-centred scale. Quadrants and rotation behave correctly, but the numbers will not tie out against a Bloomberg or Optuma RRG.

Sector points are equal-weighted baskets, not the NSE sectoral indices. Yahoo serves no price history for 10 of the 12 sectoral indices this board maps — only a live quote — so a real-index series exists for Banks and IT alone. Mixing two float-weighted indices with 21 equal-weighted baskets would put non-comparable points on one chart, so every sector is built the same way: constituents rebased to 100 and averaged.

Corporate actions are repaired, and the repair is not always enough. A split or bonus changes the share count and nothing else, so history is back-adjusted onto the post-event basis and the name carries on normally — Motilal Oswal (3:1 bonus), Paras (1:2 split) and Trent (1:2 bonus) are handled this way. A demerger is different: the company changed, so no arithmetic makes the older bars describe the business now being plotted, and comparing that reconstruction against its peers would be a confident wrong number. For those, usable history starts at the event and the name reads NA until it has enough of its own — which clears itself as the window rolls forward.

Large moves that are not on the reviewed corporate-action list are left strictly alone. F&O stocks have no daily price band, so a 25–30% day is legal and often real — Adani Enterprises in Feb 2023, IndusInd in Mar 2025, IEX in Jul 2025 — and smoothing those away would erase exactly the risk this board exists to show.

Every symbol is z-scored over an identical window. That matters more than it sounds: the same stock on the same day lands in a different spot if normalised over a different amount of history, so anything without enough history is excluded rather than rescaled.

The 3D view puts a third measure on the depth axis. RRG has no natural third axis — RS-Momentum is already the derivative of RS-Ratio, so the two are a matched pair and anything on Z is a different measure bolted on. Two are offered, each with one reading per tail point so the trail moves in depth too rather than implying the measure held still.

Volatility — trailing realised volatility, annualised. It answers what the flat plot cannot: how much risk sits behind a given relative strength. Its reference plane is the back of the box, since volatility is a magnitude with no natural zero.

Absolute return — the plain return over the stretch the tail covers, and the more pointed of the two. RRG is purely relative: both its axes are measured against the benchmark, so a security can sit deep in Leading while losing money, simply falling more slowly than the index. This axis puts that back on the chart. Its plane sits at zero, so the plane is break-even, a sphere in front of it made money, one behind it lost money, and the stem's direction is the sign. Size is the size of the move, depth is its direction. Sphere size is driven by volatility directly, not by perspective alone, so bigger = more volatile still holds after you rotate the chart; larger spheres are drawn more translucent so the volatile names in front don't hide the quiet ones behind them. Depth is still harder to read than a flat position, which is why this is a toggle beside the 2D board and not a replacement for it — the quadrant call should be made on the 2D plot.

RRG is a relative-strength tool, not a standalone buy/sell signal.
