Frequently Asked Questions (FAQs)

Q:What is the difference between S&P 500 Forward P/E and Trailing P/E?

Trailing P/E uses actual reported earnings over the past 12 months (LTM), while Forward P/E uses Wall Street consensus estimated earnings over the next 12 months (NTM EPS), making it more forward-looking for valuation.

Q:What is the historical average Forward P/E ratio for the S&P 500?

The 10-year average Forward P/E is approximately 18.2x, while the 25-year average is approximately 16.8x. Readings above 21.0x place the market in the top 10% of historical valuation percentiles.

Q:What is the relationship between high Forward P/E and subsequent 10-year returns?

Historically, starting Forward P/E multiples above 21x correlate strongly with lower subsequent 10-year annualized returns (typically 3% to 6% nominal annualized), whereas starting at Forward P/Es below 15x historically produced 10%+ annualized returns.
