Frequently Asked Questions

What do P/E and P/B percentiles mean?

A percentile shows where the current valuation sits within its own historical range. For example, a 10-year P/E percentile of 30% means today's P/E is lower than roughly 70% of trading days over the past 10 years — a relatively low position historically. The closer the percentile is to 100%, the higher the current valuation sits relative to its own history.

What's the difference between the 3-year, 5-year, 10-year, and 20-year percentiles?

Longer windows (10Y, 20Y) typically span multiple full market cycles but may include periods that are less representative of current conditions; shorter windows (3Y) track the recent market environment more closely but have a smaller sample size and are more sensitive to short-term swings. It's generally more informative to look at several windows together rather than relying on a single number.
