Sector Analysis: P/E, ROE and Dividend Yield by Sector

Q: What is a good P/E ratio for a stock?

There is no universal good P/E. A P/E of 12 may be expensive for a utility but cheap for software. Always compare to the sector median and the company's historical range.

Q: Should I use trailing or forward P/E?

Trailing P/E uses actual earnings; forward uses estimates. Forward is better for growing companies; trailing for stable earners. For cyclicals, both can mislead — use normalized earnings.

Q: What metric matters most for REITs?

Funds From Operations (FFO) replaces net income; Price/FFO replaces P/E. ROE on book equity is distorted by depreciation. Focus on FFO payout ratio, occupancy, lease duration, and same-store NOI growth.

Q: Can I build a portfolio using only sector medians?

Sector medians are a screening tool, not a complete strategy. They ignore company-specific moats, management quality, balance sheet strength, and macro trends. Use them to narrow the universe, then apply fundamental analysis.

Sector Analysis: Median P/E, ROE and Dividend Yield by Sector

TL;DR

Sector medians for P/E, ROE and dividend yield reveal why "cheap" or "expensive" is relative to industry structure
High-ROE sectors (tech, healthcare) often trade at higher P/E multiples; capital-intensive sectors (utilities, real estate) show lower ROE but higher yields
Always benchmark a stock against its sector median, not the broad market average

Why Sector Medians Matter

Valuation multiples and profitability ratios vary systematically across industries. A P/E of 15 looks cheap for software but expensive for a utility. Return on equity above 20 % is routine in asset-light businesses but rare in heavy manufacturing. Dividend yields cluster around 3–4 % in REITs and utilities while many growth sectors pay zero.

Using sector medians — not means — avoids distortion from outliers. A single mega-cap with a 100× P/E skews the average; the median reflects the typical company in that group.

The Three Core Metrics

Price-to-Earnings (P/E) Ratio

The P/E ratio divides share price by earnings per share, expressing how many years of current earnings it takes to repay the purchase price Price–earnings ratio. Two main versions exist:

Version	Earnings Basis	Typical Use
Trailing P/E	Last 12 months reported	Historical benchmark
Forward P/E	Analyst estimates for next 12 months	Growth expectations

Sectors with predictable earnings (consumer staples, utilities) trade at lower P/E ranges. Sectors with high earnings growth (semiconductors, biotech) sustain higher multiples because investors pay for future earnings, not just today's.

Return on Equity (ROE)

ROE measures net income divided by average shareholders' equity Return on equity. It shows how efficiently management turns equity capital into profit. The DuPont decomposition breaks ROE into three drivers:

Formula

ROE = Net Profit Margin × Asset Turnover × Financial Leverage

Net profit margin: operating efficiency
Asset turnover: revenue generated per dollar of assets
Financial leverage: assets financed by equity vs. debt

Asset-light sectors (software, consulting) achieve high ROE through high margins and turnover. Capital-intensive sectors (utilities, telecom) have lower turnover and often higher leverage, compressing ROE.

Dividend Yield

Dividend yield is annual dividends per share divided by current share price Dividend yield. It reflects the income component of total return. Three calculation conventions exist:

Convention	Dividends Used	When It Misleads
Trailing	Last 12 months paid	After a sharp price drop, yield spikes artificially
Forward	Annualized latest declaration	Assumes policy unchanged
Indicated	Most recent announced, annualized by frequency	May include special dividends

High yields often signal market skepticism about sustainability. REITs and utilities structurally pay high yields due to regulatory or tax requirements to distribute income Fundos de Investimento Imobiliário (FII) | B3.

Sector Median Comparison (Illustrative Ranges)

The table below shows typical median ranges observed in developed markets. Exact figures shift quarterly; treat these as reference bands, not precise current values.

Sector	Median P/E (Trailing)	Median ROE	Median Dividend Yield	Typical Drivers
Information Technology	22–30×	25–35 %	0.5–1.2 %	High margins, low assets, reinvestment
Health Care	18–25×	18–28 %	1.0–1.8 %	Pricing power, R&D amortization
Consumer Staples	16–22×	15–25 %	2.5–3.5 %	Stable demand, pricing power
Industrials	14–18×	12–18 %	1.8–2.5 %	Cyclical earnings, capex intensity
Financials (Banks)	8–12×	10–15 %	3.0–4.5 %	Leverage-driven ROE, regulated payouts
Energy	8–14×	8–14 %	3.5–5.5 %	Commodity cycles, capital intensity
Utilities	14–18×	8–12 %	3.5–4.5 %	Regulated returns, high payout ratios
Real Estate (REITs)	12–18×*	5–10 %*	3.5–5.5 %	FFO-based valuation, mandatory distribution
Materials	10–14×	8–14 %	2.0–3.5 %	Commodity pricing, asset-heavy
Communication Services	14–20×	10–18 %	1.5–3.0 %	Mix of growth (internet) and yield (telecom)

*REITs use Funds From Operations (FFO) instead of net income for P/E equivalents; ROE on book equity understates economic return due to depreciation.

How to Use Sector Medians in Practice

1. Flag Valuation Anomalies

A bank trading at 18× P/E when the sector median is 10× warrants investigation — either the market expects a turnaround, or the stock is overvalued. Conversely, a tech stock at 15× may be a value trap if growth is decelerating.

2. Assess Quality Within Sector

Compare a company's ROE to its sector median. A utility with 15 % ROE is exceptional; a software company with 15 % ROE is lagging. The DuPont breakdown reveals whether outperformance comes from margins, efficiency, or leverage.

3. Screen for Income Sustainability

In high-yield sectors (REITs, utilities, energy), compare payout ratio to sector norms. A REIT paying 95 % of FFO has less cushion than one paying 75 %. For banks, regulatory capital requirements constrain payout ratios regardless of yield.

4. Adjust for Cycle Position

Cyclical sectors (energy, materials, industrials) show depressed earnings at cycle troughs, inflating trailing P/E. Use normalized earnings (5-year average) or forward P/E for these sectors.

Cross-Sector Valuation Frameworks

Relative Value Approach

Calculate each stock's P/E relative to its sector median: Relative P/E = Stock P/E ÷ Sector Median P/E
Stocks with relative P/E below 0.8× may be undervalued; above 1.2× may be overvalued
Overlay ROE: a stock with low relative P/E and above-median ROE is a stronger candidate

Quality-Adjusted Yield

For income-focused portfolios, rank by:

Formula

Quality-Adjusted Yield = Dividend Yield × (Company ROE ÷ Sector Median ROE)

This penalizes high-yield, low-quality names and rewards sustainable payers.

Common Errors and Fixes

Error	Cause	Fix	Source
Comparing P/E across sectors without adjustment	Different growth rates, capital intensity, risk profiles	Use sector-relative P/E or PEG (P/E ÷ growth)	Price–earnings ratio
Using mean instead of median	Outliers (mega-caps, distressed names) distort average	Always use median for sector benchmarks	Price–earnings ratio
Chasing high dividend yield without payout check	Yield spikes when price falls; payout may be unsustainable	Verify payout ratio vs. sector norm; prefer forward yield	Dividend yield
Ignoring ROE decomposition	High ROE from excessive leverage masks operational weakness	Apply DuPont: check margin, turnover, leverage separately	Return on equity
Using trailing P/E for cyclicals at trough	Earnings temporarily depressed inflate ratio	Use normalized or forward earnings for cyclicals	Price–earnings ratio
Treating REIT P/E like corporate P/E	REITs report GAAP earnings including depreciation	Use P/FFO or P/AFFO for REIT valuation	Fundos de Investimento Imobiliário (FII) \| B3

Frequently Asked Questions (FAQ)

What is a good P/E ratio for a stock?

There is no universal "good" P/E. A P/E of 12 may be expensive for a utility but cheap for a software company. Always compare to the sector median and the company's own historical range.

Why do banks have lower P/E ratios than tech companies?

Banks are capital-constrained, highly leveraged, and regulated. Their earnings grow roughly with GDP, so the market applies a lower multiple. Tech companies reinvest earnings at high incremental returns, justifying higher multiples.

Is a higher ROE always better?

Not necessarily. ROE can be inflated by high financial leverage (debt). A company with 30 % ROE driven by 5× leverage is riskier than one with 20 % ROE and no debt. Use the DuPont formula to see the drivers.

How do I interpret a dividend yield above 6 %?

Yields significantly above the sector median often signal a "yield trap" — the market expects a dividend cut. Check the payout ratio, free cash flow coverage, and management commentary before buying.

Should I use trailing or forward P/E?

Trailing P/E uses actual reported earnings; forward P/E uses estimates. Forward is better for growing companies; trailing is more reliable for stable, predictable earners. For cyclicals, both can mislead — use normalized earnings.

How do sector medians differ between the U.S. and Brazil?

Brazilian sectors often trade at lower P/E multiples due to country risk, currency volatility, and higher interest rates. However, relative relationships (tech > utilities, banks < consumer staples) hold across markets. B3 provides sector indices for local benchmarking Fundos de Investimento Imobiliário (FII) | B3.

What metric matters most for REITs?

Funds From Operations (FFO) replaces net income; Price/FFO replaces P/E. ROE on book equity is distorted by depreciation. Focus on FFO payout ratio, occupancy rates, lease duration, and same-store NOI growth.

Can I build a portfolio using only sector medians?
