What it is
Sector rotation is the strategy of shifting portfolio allocation between sectors based on where we are in the economic cycle. Different sectors outperform at different cycle stages — understanding this pattern allows you to overweight sectors before they run and underweight before they fall.

"Sector rotation matlab — economy ke cycle ke hisaab se portfolio mein sectors ka weight change karna. Banking boom mein banks le lo, recession mein FMCG pe shift ho jao."

| Cycle Phase | Leading Sectors | Lagging Sectors |
|---|---|---|
| Recovery | Banks, auto, real estate, NBFCs | Pharma, FMCG |
| Expansion | Capital goods, infra, cement, metals | Utilities |
| Peak | IT (USD earners), pharma | Real estate, NBFCs |
| Slowdown | FMCG, pharma, utilities | Banks, metals, real estate |
Why it works
- Rate sensitivity: Banks and NBFCs benefit from rate cuts (lower NPA formation, credit growth). They suffer during rate hikes.
- Commodity sensitivity: Metals and chemicals rally with global demand. They collapse when demand weakens.
- Demand elasticity: FMCG/pharma have inelastic demand (people buy regardless of economy). Autos and real estate have elastic demand.
- Rupee sensitivity: IT/pharma benefit from weak rupee. Importers (oil companies) suffer.
Indian sector rotation evidence
2020-2024 cycle rotation
| Period | Phase | Top sectors | Bottom sectors |
|---|---|---|---|
| Mar–Sep 2020 | Recovery (post-COVID) | Pharma (+80%), IT (+60%) | Banks (-30%), Real estate (-40%) |
| Oct 2020–Dec 2021 | Expansion | Metals (+150%), Banks (+90%), Real estate (+120%) | Pharma (flat) |
| Jan–Jun 2022 | Peak | IT (starts falling), FMCG (flat) | Metals (-30%), Banks (volatile) |
| Jul 2022–Mar 2023 | Slowdown | FMCG (+15%), Pharma (+20%) | IT (-25%), Real estate (flat) |
| Apr 2023–2024 | New expansion | PSU Banks, Infra, Defence, Power | FMCG (flat), IT (recovering) |
Indicators for sector rotation timing
| Indicator | Signal | Sector implication |
|---|---|---|
| RBI rate cuts | Cycle turning to recovery | Go overweight: banks, NBFCs, auto, real estate |
| Credit growth > 15% | Expansion accelerating | Add: capital goods, cement, infra |
| INR depreciating | Global slowdown or risk-off | Overweight: IT, pharma (USD earners) |
| Inflation > 6% sustained | Peak/tightening | Underweight: cyclicals. Overweight: defensives |
| PMI declining below 50 | Contraction signal | Shift to defensives: FMCG, pharma, utilities |
| FII selling sustained | De-risk environment | Quality/large-cap bias; reduce small-cap cyclicals |
Implementation approaches
Approach 1: Core + Tactical (recommended)
| Layer | Allocation | What | Rotation? |
|---|---|---|---|
| Core | 60-70% | Quality compounders (sector-agnostic) | Never rotate — hold through cycles |
| Tactical | 20-30% | Cycle-sensitive positions | Rotate every 6-12 months based on indicators |
| Cash | 5-15% | Dry powder | Increase at peak, deploy at trough |
Approach 2: Full sectoral overlay
More aggressive — shift 50%+ between sectors based on cycle timing. Higher returns but higher activity and timing risk.
Common mistakes
Mistakes to avoid
- Rotating too late — By the time "banking boom" is in newspapers, banks are already up 50-80%. Sectors move BEFORE the narrative
- Over-rotating — Trading costs + taxes + timing errors erode gains. Less rotation > more rotation
- Confusing themes with cycles — "Defence is the new India story" is a narrative/theme, not a cycle rotation. Themes can last or die; cycles reliably repeat
- Ignoring sector valuations — Even the "right" sector at wrong valuation underperforms. Banking in 2024 at 2× book is different from banking at 0.8× book in 2020
- Selling compounders to rotate — Never sell Asian Paints to buy metals at peak. Tactical rotation should use FRESH capital or trim over-positions
The "never sell" sectors
Some sectors are so reliably compounding that rotation away from them hurts:
- Top-quality private banks (HDFC Bank, Kotak)
- Dominant FMCG (HUL, Nestlé)
- IT leaders (TCS, Infosys)
- Asset-light platform businesses (BSE, CAMS)
These form your CORE. Rotate only within your TACTICAL allocation.
