S&P 100 Median Trailing P/E

## What this measures

The P/E ratio of the typical S&P 100 company: half of the companies with positive earnings over the last four reported quarters are valued above this multiple and half below.

## Why it matters

The group P/E is pulled by the largest companies. The median is not, so the gap between the two shows how much a few giants decide the market's valuation.

## How to read it

A ratio: market value ÷ trailing-twelve-month GAAP net income. Companies with losses are left out of the median because a P/E on a loss has no meaning.

## What it does not say

Not a forward P/E. It uses today's S&P 100 members and current share counts back in time.
