Trailing P/E
Uses earnings per share from the last twelve reported months. Backward-looking but grounded in audited numbers. The most commonly quoted P/E figure.
Definition
What is the P/E ratio?
The P/E ratio (price-to-earnings) is a stock's share price divided by its earnings per share over a 12-month period. It tells investors how many dollars they pay for each dollar of current company earnings. A lower P/E means the stock is cheaper relative to recent profits.

Short answer
Think of P/E as the price tag in years of earnings. A P/E of 15 implies it would take fifteen years of unchanged earnings to recoup the share price. The metric is meaningless in isolation. Always compare to sector, history, growth, and balance-sheet quality. A 30x growth name can be cheap and a 9x cyclical can be expensive.
Three flavours of P/E
When a financial site reports a P/E, the version matters. Each tells a slightly different story.
Forward P/E
Uses analyst-consensus earnings forecast for the next twelve months. Reflects expectations rather than history. Sensitive to estimate revisions.
Shiller P/E
Cyclically-adjusted price-to-earnings divides price by the ten-year inflation-adjusted average of earnings. Smooths cyclical distortion and is a long-run valuation gauge for indexes.
A worked example
Coca-Cola trades around 62 dollars and earned roughly 2.50 dollars per share over the trailing twelve months. The trailing P/E is 62 divided by 2.50, or about 25. The S&P 500 long-run trailing P/E sits near 16. Coca-Cola at 25 reflects investor willingness to pay a premium for a well-moated, dollar-stable franchise.
