What is Trailing Price-To-Earnings (P/E)?
The Trailing Price-to-Earnings (P/E) ratio is a financial metric used to determine the relative value of a stock by dividing the current market price of the stock by its earnings per share over the past 12 months. Unlike its cousin, the forward P/E, which gambles on future earnings, the trailing P/E relies on the ol’ trusty—actual earnings—making it a dear friend to conservative investors who prefer a “show me the money” approach.
Why Do Analysts Use P/E?
Analysts turn to the P/E ratio to stitch an earnings-based tailored suit for comparing stocks. It helps them identify which stocks are dressed to impress with reasonable prices, and which are the financial equivalent of wearing a Hawaiian shirt to a black-tie event—overpriced and out of place. By using past earnings, the trailing P/E offers a snapshot of fiscal responsibility, or occasionally, fiscal fantasy.
Example of Inspiration and Perspiration
Imagine a company, let’s call it “GadgetCorp,” with a stock priced at $100 and a trailing EPS of $5. The math wizards among us will quickly shout “20x!"—yes, GadgetCorp has a trailing P/E ratio of 20. Now, if GadgetCorp’s stock drops to $80 with no change in earnings (perhaps investors are just having a bad day), the trailing P/E dips to 16x. Yes, cheaper stock, same old earnings! This could mean a sale sign in the world of investments, or an ominous cloud signaling trouble ahead.
Trailing vs. Forward P/E: A Tale of Two Ratios
While the trailing P/E wears its graduation cap and looks back with nostalgia, the forward P/E is all about futurism, embracing forecasts and prognostications. The Trailing P/E says, “What have you done for me lately?” while the forward P/E queries, “What will you do for me tomorrow?” Each has its place, like wisdom and youth, in the grand tapestry of stock evaluation.
Limitations - Not All that Glitters is Gold
Of course, relying solely on trailing P/E might make you the financial equivalent of a one-trick pony. Earnings aren’t always a perfect crystal ball, and sometimes what’s past isn’t prologue but rather an anomaly. Hence, the savvy investor uses the trailing P/E as one tool among many, like a chef who knows that the right dish requires more than just one spice.
