What is PE TTM?

Cfefinances

The Trailing Twelve-Month P/E (PE TTM) ratio is calculated as the current stock price divided by the sum of the company's earnings per share reported over the last 12 months. It reflects valuation based on actual reported earnings rather than forward estimates.
Think about a P/E built on the last twelve months of actual earnings. TTM means trailing twelve months — real reported numbers, not forecasts.
