What is a Very Good PE Ratio?

The Price-to-Earnings (P/E) ratio is one of the most widely used stock valuation metrics. But what constitutes a "very good" PE ratio? The answer isn't straightforward—it depends on the industry, company growth prospects, market conditions, and your investment strategy.

This article explains what makes a PE ratio "very good" and how to use this metric effectively to identify investment opportunities.

Understanding the PE Ratio

The Price-to-Earnings (P/E) ratio measures how much investors are willing to pay for each dollar of a company's earnings:

P/E Ratio = Stock Price / Earnings Per Share (EPS)

Example: If a stock trades at $50 per share and earns $5 per share, the P/E ratio is 10x ($50 ÷ $5 = 10).

This means investors are paying $10 for every $1 of earnings.

What Makes a PE Ratio "Very Good"?

A very good PE ratio depends on context, but generally:

For Value Investors

Below 15: Often considered attractive for value stocks
10-12: Very good for mature, stable companies
Below 10: Potentially excellent value (but investigate why it's so low)
Below market average: Good relative value

For Growth Investors

15-25: Reasonable for growing companies
25-35: Acceptable for high-growth companies
Above 35: Requires strong growth to justify
PEG ratio: More important than P/E alone (P/E ÷ Growth Rate)

General Guidelines

Market average: S&P 500 typically trades at 15-20x P/E
Below average: Potentially undervalued
Above average: May be overvalued (unless growth justifies it)
Historical comparison: Compare to company's own historical P/E

PE Ratio by Industry

What's considered a very good PE ratio varies significantly by industry:

Low P/E Industries (Value Sectors)

Banks: 8-12x (very good)
Utilities: 12-18x (good)
Energy: 8-15x (very good when low)
Real Estate (REITs): 10-20x (varies)
Consumer Staples: 15-20x (good)

Moderate P/E Industries

Industrials: 15-25x (good)
Consumer Discretionary: 18-25x (reasonable)
Healthcare: 20-30x (varies by subsector)
Materials: 15-20x (good)

High P/E Industries (Growth Sectors)

Technology: 25-35x+ (acceptable for growth)
Biotech: Often 30-50x+ (growth-dependent)
Software/SaaS: 30-50x+ (if growing fast)
E-commerce: 25-40x (growth-dependent)

Key Point: A PE ratio of 10 might be excellent for a bank but terrible for a high-growth tech company.

Factors That Affect What's "Very Good"

1. Growth Rate

Higher growth justifies higher P/E ratios:

No growth: P/E of 10-12 might be very good
5-10% growth: P/E of 15-20 might be very good
15-20% growth: P/E of 25-30 might be acceptable
25%+ growth: P/E of 30-40+ might be justified

2. Profitability and Margins

Companies with:

High profit margins can justify higher P/E
Consistent earnings deserve higher P/E
Predictable cash flows warrant premium multiples

3. Competitive Position

Companies with:

Strong moats can command higher P/E
Market leadership justify premium valuations
Pricing power deserve higher multiples

4. Market Conditions

During:

Bull markets: Higher P/E ratios become normal
Bear markets: Lower P/E ratios are common
Low interest rates: Higher P/E ratios are justified
High interest rates: Lower P/E ratios are expected

5. Company Lifecycle

Mature companies: Lower P/E (10-15x) is very good
Growth companies: Higher P/E (20-30x) might be acceptable
Startups: P/E may not be meaningful (focus on growth)

Using PEG Ratio for Better Analysis

The PEG ratio (Price/Earnings to Growth) provides better context than P/E alone:

PEG Ratio = P/E Ratio ÷ Annual Earnings Growth Rate

Interpretation:

PEG < 1: Potentially undervalued (very good)
PEG = 1: Fairly valued
PEG > 1: Potentially overvalued
PEG < 0.5: Potentially excellent value

Example: Stock with P/E of 20 and 15% growth rate has PEG of 1.33 (20 ÷ 15). A stock with P/E of 30 and 30% growth rate has PEG of 1.0—potentially better value despite higher P/E.

What to Watch Out For

A low P/E ratio isn't always good—investigate why:

Red Flags

Declining earnings: Low P/E might reflect falling profits
One-time gains: Earnings spike from non-recurring events
Industry decline: Sector-wide problems affecting all companies
Financial distress: Company facing bankruptcy or restructuring
Accounting issues: Earnings may not be reliable

When High P/E Might Be Justified

High growth: Company growing earnings rapidly
Turnaround: Company recovering from temporary issues
Market leader: Dominant position in growing market
Innovation: Disruptive technology or business model

Examples of Very Good PE Ratios

Example 1: Value Stock

Company: Mature bank
P/E: 10x
Growth: 5% annually
Industry average: 12x
Verdict: ✅ Very good—trading below industry average with stable earnings

Example 2: Growth Stock

Company: Tech company
P/E: 35x
Growth: 30% annually
PEG: 1.17 (35 ÷ 30)
Verdict: ✅ Reasonable—high P/E justified by high growth

Example 3: Excellent Value

Company: Consumer goods
P/E: 12x
Growth: 10% annually
PEG: 1.2 (12 ÷ 10)
Market average: 20x
Verdict: ✅ Very good—trading at significant discount to market

Key Takeaways

A very good PE ratio depends on industry, growth, and market conditions
For value stocks: P/E below 15 is often very good
For growth stocks: P/E of 25-35 might be acceptable if growth justifies it
Compare to industry averages and company's historical P/E
Use PEG ratio for better context (PEG < 1 is very good)
Investigate why P/E is low—it might indicate problems
Consider market conditions and interest rates
P/E is just one metric—use with other valuation methods

Put It Into Practice

While P/E ratio is a useful starting point, intrinsic value analysis provides a more comprehensive view. A stock with a very good P/E ratio might still be overvalued if its intrinsic value is lower, or undervalued if intrinsic value is higher.

Use Our Intrinsic Value Calculator → to analyze stocks using DCF methodology. Compare the calculated intrinsic value to market price, and consider P/E ratio as one factor in your analysis.

Remember: A very good P/E ratio is relative. What's good for one company or industry might not be good for another. Always consider context, growth prospects, and business quality when evaluating P/E ratios.
