Sector Rotation and Market Regimes: How the Economic Cycle Shifts Relative Sector Strength

Large institutional players — pension funds, hedge funds, insurance companies — do not move capital at random. They operate according to the logic of the economic cycle, interest rates, and inflation. A retail investor who understands these forces can better interpret market movements and avoid unnecessary allocation mistakes.

The Four Phases of the Economic Cycle

The economy is never in a fixed state. Analysts traditionally distinguish four phases that recur — not mechanically, but with recognisable logic:

Phase	Characteristics	GDP	Inflation	Interest Rates
Early (Recovery)	GDP rises from trough, unemployment falls	↑ fast	low/rising	low, beginning to rise
Mid (Expansion)	Strong growth, high consumer confidence	↑ steadily	moderate	moderately higher
Late (Slowdown)	Growth decelerates, inflation high, liquidity tightens	↓ slightly	high	rate peak
Recession	Contraction, layoffs, profit decline	↓	falling	central banks cut

Which Sectors Lead in Each Phase?

Historical analysis (Fidelity MSCI Sector Research, BofA Global Research) consistently reveals the following rotation:

Early (Recovery):

📈 Consumer Discretionary — consumers start spending again
📈 Industrials — corporate capital expenditure picks up
📈 Financials — credit accelerates, yield curve steepens

Mid (Expansion):

📈 Technology — companies invest in digitalisation, margins expand
📈 Energy — commodity demand peaks
📈 Communication Services — advertising markets are strong

Late (Slowdown):

📈 Energy — inflation drives oil and gas prices
📈 Materials — real assets provide inflation protection
📈 Health Care — defensive character, stable demand

Recession:

📈 Utilities — regulated revenues, bond-like character (analogous to ČEZ in the CEE context)
📈 Consumer Staples — Coca-Cola (KO), Procter & Gamble — people still eat and drink
📈 Health Care — recessions do not postpone illness

Interest Rates and Inflation as Modifiers of Relative Strength

The cycle phases alone are insufficient — two variables dramatically alter relative sector performance:

Interest Rates

Higher rates increase the discount rate applied to future cash flows. Sectors with long earnings duration — notably growth technology (NVDA, MSFT) — are more sensitive than sectors with near-term, stable cash flows.

Example: With 10-year US Treasury yields at 1 % vs. 5 %, the fair P/E multiple for NVDA (with implied 25 % p.a. growth) can differ by tens of points, whereas the fair P/E for KO (stable +3 % p.a.) changes minimally.

Rule of thumb: Utilities and REITs are "bond proxies" — they benefit from falling rates and suffer when rates rise. Financials, conversely, benefit from higher net interest margins (NIM) with a steep yield curve.

Inflation

High inflation favours real assets (commodities, energy, materials) and pricing-power companies (globally dominant brands). It hurts sectors with fixed contracts and rising input costs.

Inflation	Winners	Losers
Low and stable	Tech, Discretionary	—
Rising	Energy, Materials, Financials	Utilities, Long-duration growth
Peak / declining	Health Care, Staples	Energy, Materials

Market Regimes: BULL / BEAR / SIDEWAYS / VOLATILE

The economic cycle provides the fundamental framework, but markets do not respond to the economy instantly or linearly. This is why analysts separately identify the market regime — the state in which the overall market currently finds itself (typically measured via SPY / S&P 500).

QMA identifies the market regime based on a combination of:

Trend component — moving averages (50/200 MA), price position relative to them
Volatility component — VIX, realised volatility, return dispersion

Definitions of the Four Regimes

Regime	SPY Trend	Volatility	Typical Context
BULL	Above 200MA, 50MA > 200MA	Low–moderate	Mid/late expansion
BEAR	Below 200MA, 50MA < 200MA	High	Recession, crisis
SIDEWAYS	Around 200MA, no clear trend	Low–moderate	Phase transition, consolidation
VOLATILE	No clear trend	Very high	Shock, uncertainty, geopolitics

How the Regime Shifts Analytical Factor Weights

This is where the key institutional logic resides: the same factor does not carry the same predictive power in all regimes. Momentum works excellently in BULL markets, but in BEAR and VOLATILE conditions it generates false signals. Value screening uncovers opportunities in BEAR, but in VOLATILE conditions "value traps" are common.

QMA implements this logic within its 5-pillar scoring system, where pillar weights are dynamically adjusted to the detected market regime:

Pillar	BULL	SIDEWAYS	BEAR	VOLATILE
Momentum / Trend	↑ high	medium	↓ low	↓ low
Fundamentals / Value	medium	↑ high	↑ high	medium
Quality (margins, debt)	medium	medium	↑ high	↑ high
Sentiment / Smart Money	medium	medium	↑ high	↑ high
Macro / Sector	medium	↑ high	↑ high	↑ high

Why this matters: In a BEAR regime, filtering primarily for momentum breakouts is counterproductive — what matters more is whether the company has a strong balance sheet and institutional backing. In a BULL regime, by contrast, trend and momentum are the dominant predictors of continued movement.

Practical Example: A 1,000,000 CZK Portfolio and Sector Rotation

Consider a hypothetical model example (purely illustrative — not a recommendation):

Macro context: Transition from Late to Recession phase, central bank has halted rate hikes, VIX above 25, SPY below 200MA → QMA detects a BEAR regime.

Historical logic (not a guarantee) suggests that under the rotation model, a portfolio manager would evaluate a shift in allocation:

Reduce weights: Technology (NVDA, MSFT) — long earnings duration, high discount-rate sensitivity
Increase weights: Consumer Staples (KO), Health Care, Utilities (analogy: ČEZ in a CEE portfolio context)
Focus on: Quality screen — companies with low leverage (D/E < 0.5), strong FCF margin

The model works with a 1,000,000 CZK allocation:

Original allocation: 40 % Tech / 30 % Industrials / 30 % Financials
Post-rotation per macro logic: 15 % Tech / 15 % Industrials / 20 % Financials / 25 % Staples+Health / 25 % Utilities

How to Do This in QMA

QMA provides several tools that directly support macro analysis and sector rotation:

🔎 /smart-money — Sector Strength and Institutional Flows

The /smart-money section displays relative sector strength — which industries are attracting institutional capital and which are losing it. The platform surfaces changes in large-player positioning (based on publicly available data such as 13F filings, options flow, dark pool activity), allowing analysts to determine whether the current sector rotation aligns with the cycle phase or whether anomalies (early movers) are present.

📊 /screener — Filtering in Regime Context

On /screener, macro filters (sector, market cap) can be combined with fundamental and technical criteria. In a BEAR regime, an analyst would typically add filters such as FCF yield > 5 %, D/E < 0.5, Beta < 1 — corresponding to a defensive screen.

📈 /stocks/[symbol] — Detailed Sector-Level Context

The /stocks/AAPL, /stocks/KO pages display how a specific stock fits within the current macro and sector context — including QMA pillar scores and how the weights are set for the detected market regime.

🎯 /strategy — Defining Macro Rules

In /strategy, macro conditions can be incorporated as part of the investment process — e.g., a rule stating "if market regime = BEAR, prioritise Utilities and Health Care sectors with Quality score > 7". The system then filters opportunities in accordance with these rules.

📒 /journal — Documenting Decisions

/journal is used to record the macro thesis — e.g., "entering recession rotation, reducing tech, increasing defensives" — and to subsequently review whether the decision reflected the detected regime and how it developed over time.

Limitations of Sector Rotation as an Approach

It is important to acknowledge the weaknesses:

Timing is extremely difficult — phase transitions are unclear in real time, and phases last for varying durations
Sector overlap — technology companies today incorporate elements of Industrials and Staples (AAPL as a "lifestyle staple")
Geopolitical shocks (such as the 2022 energy crisis) can disrupt standard rotation for many months
Historical correlation ≠ future performance — sector rotation is a statistical tendency, not a deterministic law
