Trailing vs forward P/E
Trailing P/E uses the most recent 12 months of actual reported earnings. It's based on known data.
Forward P/E uses analyst estimates for the next 12 months of earnings. It incorporates expectations about the future but is based on predictions that may prove wrong.
For dividend investors focused on sustainability, trailing P/E using actual earnings is generally more reliable. Forward P/E can look artificially low if analysts are optimistic.
P/E ratios across sectors
P/E ratios vary significantly by sector and shouldn't be compared across industries:
- Utilities: Often trade at 15–20× (stable, predictable earnings)
- Consumer Staples: Typically 20–28× (premium for defensive quality)
- Technology: Often 25–40× (growth premium)
- Financials: Often 10–15× (lower multiples for banking businesses)
- REITs: P/E is misleading; use funds from operations instead
P/E and dividend stocks
High-quality dividend growers — Dividend Aristocrats in consumer staples and healthcare — often trade at premium P/E ratios (20–30×) because the market pays up for consistency. This doesn't necessarily make them overvalued; it reflects a genuine premium for reliability.
The risk: when markets broadly re-rate from high to lower P/E multiples (as in 2022), even high-quality defensive dividend stocks fall in price despite unchanged business fundamentals.
