Ever notice how banks lead the market for a stretch, then IT suddenly takes over, then metals catch a bid on some commodity move? That handover is sector rotation: money moving between sectors as market leadership changes hands over a cycle. One group of stocks outperforms the broader market while another lags, and those roles gradually reverse as conditions shift. It’s a genuinely persistent pattern in the Indian market, and each phase reflects a real change in flows, rates, earnings or global cues rather than random noise. A Relative Rotation Graph (RRG) is the standard tool for seeing this visually. Instead of scanning a table of sector returns, an RRG turns each sector’s relative performance into a moving dot with a trailing path, so the rotation itself becomes the thing you’re actually looking at.
What is sector rotation?
At any point in time, some NSE sectors are beating the Nifty 50 and some are trailing it. Sector rotation is simply the observation that this leadership isn’t static: it moves. A sector that’s been the market’s strongest performer for weeks can lose that edge as the conditions that favoured it change, while a sector that had been quietly lagging can start picking up relative strength as new catalysts appear. Over a full market cycle, this produces a recognisable, if never perfectly repeating, sequence of sectors taking turns leading and lagging.
Understanding rotation matters because relative performance, not just absolute performance, is often where the real opportunity sits. A sector can be rising in absolute terms and still be a poor place to be if it’s lagging the broader market. The reverse is true too: a sector can be quietly building relative strength while its own price action looks unremarkable.
What drives sector rotation in the Indian market?
A handful of forces tend to be behind most sector rotations on the NSE:
- FII and DII flows. Institutional flows often concentrate in particular sectors over a stretch, say a wave of FII buying into financials, or DII allocation shifting toward consumption names, and that concentrated flow is a common trigger for a sector’s relative strength to turn.
- The interest rate cycle. Expectations around rate cuts or hikes move rate-sensitive sectors first, since banks, autos, realty and NBFCs are directly affected by the cost of borrowing and, for banks, net interest margins.
- Earnings season. As quarterly results roll in sector by sector, individual sectors can reprice sharply based on whether results and commentary beat or disappoint, shifting relative strength independent of the broader market.
- Commodity prices. Moves in crude oil, metals or agricultural commodities feed directly into sectors like energy, metals and chemicals, often decoupling their performance from the rest of the market for a period.
None of these operate in isolation. A rotation is usually the combined effect of two or more forces reinforcing each other, which is part of why rotations, once established, tend to persist rather than reverse immediately.
What is a Relative Rotation Graph (RRG)?
An RRG plots two derived measures for each sector against a benchmark (on the StockMojo chart, the Nifty 50) on a single scatter chart:
- RS-Ratio on the horizontal axis: the sector’s relative strength against the benchmark, normalised so that a reading above 100 means the sector is outperforming and below 100 means it’s underperforming.
- RS-Momentum on the vertical axis: the rate of change of that relative strength, showing not just whether the sector is outperforming, but whether that outperformance is accelerating or decelerating.
Each sector shows up as a single dot, with a tail behind it tracing its recent positions on the chart. Watching several sectors move on the same graph is what makes an RRG useful: it turns relative-return numbers, which are hard to compare intuitively, into a single visual field where each sector’s direction and speed of rotation is immediately visible. The Sector Rotation RRG tool tracks 18 NSE sectoral and thematic indices against the Nifty 50 on exactly this chart.
What do the four quadrants mean?
The two axes divide the RRG into four quadrants, and where a sector’s dot sits tells you both its current relative standing and its momentum:
| Quadrant | Position | RS-Ratio | RS-Momentum | Reading |
|---|---|---|---|---|
| Leading | Top-right | Above 100 (outperforming) | Positive (still gaining) | Strongest phase: sector is beating the benchmark and still accelerating |
| Weakening | Bottom-right | Above 100 (outperforming) | Negative (losing steam) | Still ahead of the benchmark, but the outperformance is fading |
| Lagging | Bottom-left | Below 100 (underperforming) | Negative (still losing) | Weakest phase: sector is behind the benchmark and still falling further behind |
| Improving | Top-left | Below 100 (underperforming) | Positive (starting to gain) | Still behind the benchmark, but relative strength is turning up |
Sectors tend to rotate through these four quadrants in a broadly clockwise sequence: Improving into Leading, Leading into Weakening, Weakening into Lagging, and eventually Lagging back into Improving as the cycle turns again. That’s a useful mental model for anticipating where a sector might head next, though it’s a tendency rather than a rule. Sectors can reverse, stall, or loop back the way they came.
How do you identify a real rotation, and avoid noise?
The dot’s current quadrant only tells you where a sector stands right now. It’s the tail that tells you whether the move is real. A long, straight tail moving cleanly through a quadrant reflects a persistent, well-established rotation, while a short tail, or one hooking back on itself, suggests the sector’s relative strength is indecisive or reversing. Reading too much into a single day’s quadrant can mislead you.
Two practical checks help separate a genuine rotation from short-term noise:
- Switch between Daily and Weekly mode. Daily mode reacts faster to recent price action, which makes it more responsive but noisier: a sector can flicker between quadrants on moves that don’t hold up. Weekly mode smooths this out into a more structural read, so a rotation showing up consistently in both modes is more trustworthy than one appearing only intraday.
- Confirm with index contributors. A sector index can look like it’s rotating simply because one or two heavyweight constituents moved sharply. Checking index contributors shows whether the move is broad-based across constituents or concentrated in a handful of names. Broad participation is the stronger sign of a genuine rotation.
Market breadth data from the advance-decline tool is a further sanity check. A sector genuinely gaining relative strength usually shows a healthier breadth picture underneath it, not just a couple of large stocks doing the work.
How do you trade sector rotation?
The most common approaches map directly onto the quadrants. Sectors in or freshly entering Leading already show both outperformance and momentum, making them a natural place to look for relative strength trades. Sectors in Improving are higher-risk, higher-reward: strength is only just turning up, so being early can pay off if the rotation continues into Leading, but it can also reverse. Sectors sliding through Weakening into Lagging are typically where positions get trimmed, since both performance and momentum are working against you.
The RRG works best alongside price action and contributor confirmation, not as a signal traded alone. A dot’s quadrant shows the rotation’s current phase, not its cause, and the index weightage of a sector’s constituents helps you judge how much one large stock could be skewing the picture.

Key terms
- Sector rotation: the shift of relative market leadership between sectors over a cycle, as one group of stocks outperforms and another lags.
- Relative Rotation Graph (RRG): a chart plotting a sector’s RS-Ratio against its RS-Momentum, visualising rotation as a moving dot with a trailing path.
- RS-Ratio: a sector’s relative strength against a benchmark; above 100 means outperformance, below 100 means underperformance.
- RS-Momentum: the rate of change of RS-Ratio; whether relative strength is accelerating or decelerating.
- Quadrants (Leading, Weakening, Lagging, Improving): the four zones of the RRG, which sectors tend to move through in a broadly clockwise sequence.
- Tail: the trailing path behind a sector’s RRG dot; its length and shape distinguish a persistent rotation from short-term noise.
