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:
- 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:
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?
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.
