What are the flaws with public company comparables?

• A. There is never a 100% comparable
• B. The stock market contains emotion
• C. Share prices for small companies with thinly-traded stocks may not reflect their full value
• D. All of the above

Answer: (D)

Public company comparables are useful, but they have notable flaws. First, there is rarely a perfect match—no two companies are identical in business mix, margins, growth, leverage, geography, or capital structure. Even peers within the same industry differ in meaningful ways, so you can’t expect a 100% apples-to-apples comparison; adjustments help, but they can’t remove all differences. Second, the stock price and multiples reflect what investors think now, including sentiment, momentum, and macro headlines. This market psychology can push valuations away from underlying fundamentals in the short term, which can distort how comparable multiples behave. Third, for small or thinly traded stocks, prices can be illiquid and not reflect the company’s true value; wide bid-ask spreads and trading limits can distort market pricing, making those examples less reliable as comps. Taken together, these issues explain why relying on public company comparables requires caution, and why all of the above is cited as the flaw.
