Introduction

Two companies in the same sector can trade at very different prices in the stock market. One stock keeps rising while another barely moves, even though both operate in similar businesses. For investors, the real question becomes simple: is the higher price justified, or is the market overpaying?

This is where relative valuation becomes useful. Instead of estimating a company’s exact intrinsic value, relative valuation compares a business with similar companies in the market. By looking at common metrics and market multiples, investors can quickly judge whether a stock looks expensive, fairly priced, or potentially undervalued.

The idea is straightforward. Rather than analysing a company in isolation, you evaluate it alongside its peers. This comparison helps investors understand whether a stock’s price reflects real business strength or simply market enthusiasm.

Understanding Relative Valuation

Relative valuation determines a company’s value by comparing valuation multiples, such as Price-to-Earnings (P/E), Price-to-Book (P/B), or Enterprise Value-to-EBITDA, to similar companies in the same industry or to market indices.

For example, consider two large private-sector banks in India: HDFC Bank and ICICI Bank. Both operate in the same sector and serve similar customer segments. If HDFC Bank trades at a higher P/E multiple than ICICI Bank, investors usually expect stronger asset quality, better growth visibility, or more consistent profitability to justify that premium. If those advantages are not present, the higher valuation may indicate the stock is expensive relative to its peers.

The core principle is simple: similar companies should trade at similar multiples, adjusted for growth rates, profitability, and risk factors. If Company A trades at 30× P/E while its peers average 20×, investors are paying a 50% premium, which should be supported by stronger fundamentals.

SEBI guidelines encourage registered research analysts to use appropriate valuation methodologies, including relative valuation, while maintaining transparency in assumptions and peer selection.

Common Relative Valuation Methods

P/E RatioMarket Price ÷ Earnings per ShareMost sectors, growth companiesNifty 50 at 22-23x
P/B RatioMarket Price ÷ Book Value per ShareBanks, capital-intensive sectorsBSE Bankex at 2.5-3x

Sector-wise P/E ratios vary significantly: IT averages 28-30x, FMCG 45-50x, Auto 20-25x, and Pharma 25-30x, enabling meaningful peer comparisons.

Advantages and Limitations

Why investors use relative valuation:

  • Simpler and faster than intrinsic valuation methods
  • Uses real market data reflecting current sentiment
  • Easier for retail investors to understand and apply
  • Provides a quick comparison across multiple stocks

Critical limitations to consider:

  • Assumes the market correctly values peer companies (not true during bubbles or crashes)
  • Doesn’t account for company-specific competitive advantages
  • Can mislead if the entire sector is overvalued or undervalued
  • Not suitable for loss-making companies or unique business models without comparable peers

Investment Approach

Relative valuation is a useful starting point because it quickly shows how the market prices a company relative to its peers. However, numbers alone rarely tell the full story. Regulators such as the Securities and Exchange Board of India encourage investors to combine valuation metrics with deeper fundamental analysis that examines financial statements, business models, and management quality.

Context is what turns a simple ratio into meaningful insight. A low P/E ratio may indicate that a stock is undervalued, but it can also signal weak growth prospects, poor asset quality, or declining earnings. Similarly, a high P/E ratio might suggest that a stock is expensive, yet it could also reflect strong growth expectations, market leadership, or a business with superior profitability.

For investors, the real advantage of relative valuation lies in how it complements broader analysis. Use it to compare companies, identify potential mispricing, and narrow down opportunities. Then evaluate the underlying fundamentals to decide whether the price truly reflects the company’s long-term potential.

FAQs

1. What is the difference between relative and absolute valuation?

Relative valuation compares companies using market multiples such as P/E or P/B, while absolute valuation (DCF) calculates intrinsic value based on future cash flows and requires detailed financial projections.

2. Which relative valuation method is best for Indian stocks?

The P/E ratio is most commonly used, but the best method depends on the sector: P/B for banks and EV/EBITDA for capital-intensive industries. No single method suits all companies.

3. Can relative valuation be used for all types of companies?

Not suitable for loss-making companies with negative P/E, startups without earnings history, or unique business models lacking comparable peers in the market.

4. Is a low P/E ratio always better?

Not necessarily. A low P/E may indicate undervaluation or fundamental problems, while a high P/E may signal overvaluation or high growth expectations. Context and sector norms matter.
