How to Evaluate Stock Value – Relative Valuation Methods Explained: When evaluating stock value, it’s crucial for investors to determine whether a stock is fairly valued, undervalued, or overvalued. Relative valuation is a highly effective method for making this assessment. By comparing a stock’s value to that of similar companies or industry averages, investors can gain valuable insights into the stock’s relative worth. This article explains the best-known methods for determining a stock’s relative value, the pros and cons of these methods, and how they compare to absolute valuation models.
What is Relative Valuation?
Relative valuation involves comparing a stock to other similar stocks or industry benchmarks to assess its value. It provides context by evaluating how a stock is valued relative to others in the market. This method relies on financial ratios and metrics to make comparisons.
Best-Known Methods for Determining Relative Value
1. Price-to-Earnings (P/E) Ratio
The P/E ratio is one of the most widely used metrics in relative valuation. It compares a company’s current share price to its earnings per share (EPS).
$$
\text{P/E Ratio} = \frac{\text{Share Price}}{\text{Earnings Per Share (EPS)}}
$$
Pros:
- Simplicity: Easy to calculate and widely understood.
- Comparability: Useful for comparing companies within the same industry.
Cons:
- Earnings Volatility: Can be misleading if earnings are highly volatile.
- Differences in Growth: Companies with different growth rates may have different P/E ratios.
2. Price-to-Book (P/B) Ratio
The P/B ratio compares a company’s market value to its book value.
$$
\text{P/B Ratio} = \frac{\text{Market Value}}{\text{Book Value}}
$$
Pros:
- Asset-Based: Useful for companies with significant tangible assets.
- Stability: Less affected by earnings volatility.
Cons:
- Intangible Assets: Does not account well for companies with significant intangible assets.
- Industry Variability: Can vary widely between industries.
3. Price-to-Sales (P/S) Ratio
The P/S ratio compares a company’s stock price to its revenue per share.
$$
\text{P/S Ratio} = \frac{\text{Market Capitalization}}{\text{Total Sales}}
$$
Pros:
- Revenue Focused: Useful for companies with little or no earnings.
- Less Manipulable: Revenue is less subject to accounting manipulation compared to earnings.
Cons:
- Profitability Ignored: Does not consider whether the company is profitable.
- Margin Variability: Companies with different profit margins can have similar P/S ratios but very different financial health.
How to Find Information for Relative Valuation
To calculate these ratios, you need specific financial information:
- Share Price: Available on financial news websites and stock exchanges.
- Earnings Per Share (EPS): Found in a company’s income statement or quarterly earnings reports.
- Book Value: Located in the company’s balance sheet.
- Total Sales/Revenue: Found in the income statement.
Relative Valuation vs. Absolute Valuation
Relative Valuation:
- Basis: Compares a stock to others in the market.
- Key Metrics: P/E ratio, P/B ratio, P/S ratio, etc.
- Pros: Provides market context, easy to understand, useful for comparing peers.
- Cons: May not reflect intrinsic value, affected by market conditions and peers’ performance.
Absolute Valuation:
- Basis: Determines the intrinsic value of a stock using fundamental analysis.
- Key Models: Discounted Cash Flow (DCF) analysis, Dividend Discount Model (DDM).
- Pros: Focuses on the company’s intrinsic value, not influenced by market conditions.
- Cons: Requires detailed financial projections and assumptions, more complex.
Example: Comparing Relative Valuation and Absolute Valuation
Apple Inc. (AAPL):
- Relative Valuation: Using the P/E ratio, you compare Apple’s P/E to other tech companies. If Apple’s P/E is lower than its peers, it might be undervalued.
- Absolute Valuation: Using the DCF model, you project Apple’s future cash flows and discount them to present value to determine its intrinsic value. If this value is higher than the current market price, Apple might be undervalued.
Limitations of the Relative Value Model
- Market Conditions: Relative valuation can be skewed during market bubbles or crashes.
- Peer Selection: Choosing the wrong peer group can lead to incorrect conclusions.
- Growth Rates: Differences in growth rates between companies can make comparisons misleading.
The Impact of Assumptions to your Absolute & Relative Valuation Model
Assumptions play a critical role in both relative and absolute valuation models. For relative valuation:
- Industry Averages: Assuming industry averages are accurate can be risky if the industry is experiencing unusual conditions.
- Growth Assumptions: Incorrect growth rate assumptions can distort ratios like the P/E ratio.
Ensuring a Margin of Safety
To mitigate risks, investors should:
- Use Multiple Ratios: Relying on several valuation ratios provides a more comprehensive view.
- Cross-Check with Absolute Valuation: Use absolute valuation models to validate relative valuation conclusions.
- Adjust for Risk: Consider the company’s risk profile and adjust valuation metrics accordingly.
Real-World Examples
- Amazon (AMZN):
- Relative Valuation: Often considered expensive based on P/E ratio but justified by high growth rates.
- Absolute Valuation: Using a DCF model can help understand if the high P/E is warranted by future cash flows.
- Tesla (TSLA):
- Relative Valuation: Tesla’s P/E ratio is often much higher than traditional automakers.
- Absolute Valuation: Investors use growth projections and DCF to justify high valuations based on expected future growth.
Relative Valuation Conclusion
Relative valuation is a valuable tool for investors to assess whether a stock is fairly valued compared to its peers. While methods like the P/E, P/B, and P/S ratios provide quick and easy comparisons, they have limitations and should be used in conjunction with absolute valuation models to get a fuller picture. By understanding both relative and absolute valuation methods, investors can make more informed decisions, ensuring they account for market conditions, industry differences, and the company’s growth prospects.
Incorporating a margin of safety and cross-verifying with different valuation models helps mitigate risks and improves the reliability of investment decisions. Whether evaluating tech giants like Apple or high-growth companies like Tesla, using these models effectively can enhance investment strategies and outcomes.
Final Thoughts
By understanding and analyzing relative value models, investors can better assess a company’s potential for long-term growth and financial health, making more informed investment decisions. Using a combination of relative and absolute valuation methods, along with a margin of safety, can help investors navigate the complexities of the stock market and achieve more reliable investment outcomes.
