Regarding the P/E multiple, which statement is generally true?

• A. The P/E multiple is not terribly useful in most cases because it's affected by different tax rates, capital structures, non-core-business activities, and more; it is often used for completeness.
• B. It is the most reliable valuation metric across industries.
• C. It is unaffected by differences in tax rates among companies.
• D. It is always the best starting point for valuations.

Answer: (A)

The P/E multiple can be distorted by factors that don’t reflect the underlying business value, so it isn’t terribly useful for clean cross-company comparisons. Earnings per share come after taxes and financing decisions, so differences in tax rates and capital structure directly affect earnings—and thus the P/E ratio—even if the operating business is similar. If one company has higher leverage, higher taxes, or non-core or one-time items, its net income can be higher or lower for reasons unrelated to the core profitability of the business. Because of these distortions, the P/E is often used only as a rough checkpoint or for completeness rather than as a reliable, universal comparator across industries. Other valuation metrics may be preferred in practice because they reduce sensitivity to taxes and financing choices, and valuation typically relies on a combination of measures rather than a single starting point.
