Questions: Price-to-Earnings Multiples and Comparable Company Valuation

Question 1

Company A and Company B are in the same industry and both trade at a P/E of 20. An analyst concludes they are equally valued by the market. What is wrong with this conclusion?

• A. Nothing — identical P/E ratios in the same industry confirm equivalent valuation
• B. P/E should be compared to EV/EBITDA before drawing any conclusions
• C. The identical multiple could reflect completely different growth rates, risk profiles, or payout ratios that happen to produce the same P/E
• D. P/E is only valid for companies with positive earnings, so one company may have negative earnings

Answer: (C)

The theoretical P/E = payout ratio / (r - g). Two firms can reach P/E = 20 via very different combinations: high payout + low growth + low risk might equal 20, as could low payout + high growth + high risk. The multiple compresses all these drivers into one number, hiding what actually explains the valuation. Equal P/E ratios do not imply equivalent businesses, equivalent risk, or equivalent future returns — they only indicate the market currently prices each dollar of earnings at 20 dollars. Understanding what drives the multiple is essential before acting on a comparison.

Question 2

An analyst is comparing a heavily leveraged company to a competitor with no debt. Why is EV/EBITDA generally preferred over P/E for this comparison?

• A. EV/EBITDA is always higher than P/E, making it easier to spot undervaluation
• B. EV/EBITDA uses enterprise value and pre-financing earnings, removing the distortion caused by different capital structures
• C. P/E is affected by accounting choices for depreciation, while EV/EBITDA is not
• D. EV/EBITDA is the only multiple accepted by regulators for public company comparisons

Answer: (B)

P/E is an equity multiple — it measures market cap divided by net income, which sits below interest expense on the income statement. A highly leveraged company has large interest charges that depress net income, making its P/E look artificially inflated relative to an unlevered peer. EV/EBITDA sidesteps this by using enterprise value (equity + net debt) in the numerator and EBITDA (earnings before interest and taxes, plus D&A) in the denominator. Both numerator and denominator are capital-structure-neutral, so the multiple reflects operating performance independent of financing choices. Option C is partially true but secondary to the leverage distortion.

Question 3

All else being equal, a company with a lower required rate of return (r) should trade at a higher P/E ratio.

• T. True
• F. False

Answer: True

The theoretical P/E = payout ratio / (r - g). The required return r appears in the denominator: as r decreases, the denominator shrinks and P/E rises. A lower required return means investors need less compensation for holding the stock — typically because it has lower risk (lower beta, more stable earnings). Lower-risk stocks are worth more relative to their current earnings because the future earnings stream is discounted less severely. This is why low-volatility, blue-chip companies often command premium P/E multiples even with modest growth expectations.

Question 4

A stock trading at a P/E below its industry peers is necessarily undervalued and represents a buying opportunity.

• T. True
• F. False

Answer: False

This is the central misconception of simple multiple analysis. The theoretical P/E = payout ratio / (r - g). A below-peer P/E could reflect: lower expected growth g (making the denominator larger), higher required return r due to higher risk, lower payout ratio, or genuine mispricing. The multiple alone cannot distinguish these. A company with a P/E of 10 vs. a peer P/E of 15 might be cheap — or it might have lower growth prospects, higher leverage risk, or structural competitive disadvantages that fully justify the discount. Multiples are starting points for investigation, not conclusions.

Question 5

Why do equity analysts use multiples-based valuation alongside DCF analysis rather than relying on one method alone?

Model answer: Each method has distinct failure modes. DCF is highly sensitive to terminal growth rate and discount rate assumptions — small changes in inputs produce large swings in value, so the output can be precisely wrong. Multiples-based analysis is grounded in what the market actually pays for comparable businesses, but it assumes the peer group is correctly priced and that the subject company is genuinely comparable. Using both methods together provides triangulation: if the DCF says a stock is worth $50 but comparable companies imply $25, the analyst must explain the gap — perhaps the DCF growth assumptions are too optimistic, or the company has genuine advantages not reflected in the peer median. Agreement between methods increases confidence; divergence flags assumptions to scrutinize.

The triangulation principle is key: relative valuation (multiples) anchors analysis in market reality; intrinsic valuation (DCF) anchors it in fundamental cash flows. Neither is authoritative alone. Multiples can be uniformly wrong if the entire peer group is mispriced (as in bubbles). DCFs can be uniformly wrong if the analyst's model misspecifies growth or risk. Analysts present both because the overlap and divergence between them is itself informative about where risk and uncertainty in the valuation lie.
