Imagine this not-so-unusual scenario: A company with a price-to-earnings (P/E) ratio of 77 also has a projected P/E of 22. How is it expected to change so quickly? Let's see.
Envision the Three-Legged Chair Company (ticker: OOOPS). If its stock currently trades at $77 per share and has $1 per share in annual earnings, its P/E is 77. Let's say it's growing rapidly, though, and is expected to earn $3.50 next year. If so, the projected P/E for that year is 22 ($77 divided by $3.50 is 22).
With a firm that's growing briskly, if the earnings grow more quickly than the stock price, the P/E ratio for future years will decrease noticeably.
