P/E, Forward P/E, and P/B made simple
Learn the three most common valuation metrics and when each one is useful.
Key takeaways
- P/E compares price with earnings power.
- Forward P/E uses expected earnings, so it depends on assumptions.
- P/B is useful for asset-heavy sectors like banking and insurance.

Valuation ladder in plain English
P/E in plain English
P/E asks: how much are investors paying for each naira of earnings today? Lower is not always better, but very high values need stronger growth.
Forward P/E
Forward P/E uses projected earnings. It can be helpful when growth is changing quickly, but projections can be wrong.
P/B ratio
P/B compares price to book value. It can highlight when a stock is priced rich versus its balance-sheet base, especially in financial stocks.
Simple illustration
Valuation ratios are price tags: they help you compare what you are paying for earnings or assets, not predict tomorrow’s price.
Worked example
Two banks have similar growth.
- Bank A: P/E 6, P/B 0.9. Bank B: P/E 14, P/B 2.1.
- Ask what justifies the premium for Bank B (better quality, growth, governance?).
- If no strong reason, the lower-valued stock may offer better risk/reward.
Takeaway: Always connect valuation to business quality.
