Investment Fundamentals: A Comprehensive Guide to Six Corporate Valuation Methods—DCF, P/E, P/B, and More

P/S = Market Capitalization ÷ Annual Revenue — measures how much the market is willing to pay for each RMB 1 of revenue. P/S is commonly used for early-stage, high-growth technology companies. Key prerequisites for using P/S: • High-quality revenue that can sustain growth; • A proven business model, with margins expected to improve as scale increases; • A clear industry competitive landscape—not a pure “burn-rate” game. Practical tip: Misuse of P/S is common during bull markets. Assigning a 10x P/S multiple to a company that has never turned a profit and whose business model remains unproven constitutes speculation—not investment. A high P/S ratio is not inherently wrong, but it must be justified by high-quality growth. Method Six: Comparable Company Analysis (Comps) Comparable Company Analysis is the most widely used valuation method in investment banking and M&A. Its logic is simple and direct: Identify a group of publicly traded companies with similar businesses, comparable scale, and operating in similar markets; examine their current valuation multiples; then apply a discount or premium to adjust for the target company’s relative strengths or weaknesses. Implementation Steps: 4. Screen for comparable companies (similar business, comparable size, same market); 5. Collect valuation metrics such as P/E, EV/EBITDA, and P/S for these peers; 6. Calculate the median or mean of those multiples; 7. Adjust for the target company’s competitive advantages or disadvantages (typically ±20%–30%); 8. Derive a valuation range. The essence of Comparable Company Analysis: Similar businesses command similar market valuations. It is not an absolute valuation method, but rather tells you whether the target company is relatively expensive or cheap versus its peers. III. How to Choose the Right Valuation Method? No single method fits all companies. The key is to select based on the company’s life stage, industry characteristics, and profitability. Company Type Recommended Method Supplementary Reference Mature & Stable (e.g., Food/Consumer) P/E, DCF Dividend Yield Banks / Insurance / Real Estate P/B, ROE Analysis Dividend Yield Capital-Intensive (e.g., Energy/Chemicals) EV/EBITDA, DCF P/B High-Growth Tech Companies P/S, DCF (Forward-looking) Rule of 40 Unprofitable Startups P/S, GMV / User Count Comparable Company Analysis M&A / IPO Pricing Comparable Company Analysis DCF, Premium Analysis Practical Principle: Relying on a single method may introduce bias; using multiple methods for cross-validation strengthens credibility. IV. Five Common Valuation Pitfalls Pitfall One: “More precision is always better” Many investors spend excessive time building models—calculating DCF down to two decimal places. But as Warren Buffett said: “It’s far better to be approximately right than precisely wrong.” Valuation is fundamentally a judgment about the future—and thus inherently uncertain. Obsessing over precision is merely self-comfort. A better approach is to present a valuation range, clearly articulating the logic and assumptions behind each scenario. Pitfall Two: “Low P/E means cheap” This is the most frequent mistake made by retail investors. A low P/E may signal that the company is at a cyclical trough, with profits poised to decline; that the market has applied a risk discount; or that growth potential has peaked. Buying solely because of a low P/E—without considering industry context, growth prospects, and asset quality—often leads to value traps. Pitfall Three: Applying the Same Valuation Method Across Different Industries Banks and tech companies cannot be compared using the same P/E metric—their profit calculation methodologies and asset quality differ fundamentally.

How to Estimate a Stock’s Price?

Stock valuation methods generally fall into three categories: absolute valuation, relative valuation, and hybrid valuation. When buying a stock, investors typically conduct fundamental analysis—or valuation—to assess whether its price is inflated. Absolute valuation requires investors to make accurate forecasts about the company’s future performance; the forecasting process itself constitutes an initial valuation exercise. Hybrid valuation combines absolute and relative valuation methods through weighted integration to derive a target price. Relative valuation, however, is best suited for most investors: it is intuitive, easy to grasp, and—given the inherent uncertainties in valuation—offers sufficient practical guidance for stock selection. A rough estimate is often all you need to make sound investment decisions. 1. Price-to-Earnings Ratio (P/E) = Market Price per Share ÷ Earnings per Share China’s stock market is relatively immature and retains a speculative atmosphere. Moreover, newly listed stocks rarely trade at P/E ratios below 20x. A P/E below 20x suggests insufficient returns for both primary and secondary market participants—i.e., neither issuers nor investors can profit adequately. New share offerings are fiercely contested, with abysmally low subscription rates. Even during bear markets, demand consistently outstrips supply. Initial public offerings frequently debut at P/E ratios above 30x, and many soar sharply on their first trading day. This dynamic has pushed up the overall P/E level across China’s equity market.
