What is a normal P/E ratio?

Historical S&P 500 average P/E: approximately 16-17x. Current 2024 S&P 500 forward P/E: approximately 20-22x. Tech sector: 25-40x. Value sectors: 10-15x.

Trailing vs forward P/E: which is better?

Trailing P/E uses actual historical earnings (objective but backward-looking). Forward P/E uses analyst estimates (more relevant but subject to estimation error).

What does a very low P/E mean?

Low P/E can mean undervaluation, value trap, cyclical peak earnings, deteriorating business quality, or sector rotation out of favor. Always understand WHY the P/E is low before assuming it is cheap.
