forward p/e
Forward P/E is a share price ratio that divides today's price by a company's expected future earnings, not its past ones.
In plain English
Here is the strange part. The most popular number investors use to judge whether a share is cheap or costly is built entirely on a guess that has not happened yet.
Forward P/E takes the current share price and divides it by the earnings a company is forecast to make over the next twelve months, usually estimated by analysts who study the company closely. Compare that to the regular P/E, which uses earnings the company has already reported, numbers that are settled and cannot change. Forward P/E is betting on tomorrow, and tomorrow has a way of surprising everyone.
Say a Nigerian investor is looking at MTN Nigeria. If the share trades at ₦220 and analysts expect the company to earn ₦20 per share next year, the forward P/E is 11. That looks attractive next to a rival trading at a forward P/E of 18, until you remember that the 11 depends on MTN actually hitting that ₦20 forecast. If naira depreciation or a regulatory fine eats into profit, that tidy 11 can calmly become 15 once the real numbers land.
This matters for someone in London deciding whether to top up an investment platform holding with shares like Shell or Barclays. A low forward P/E can mean a genuine bargain, or it can mean the market already suspects the earnings forecast is too rosy and is pricing in disappointment ahead of time. The ratio never tells you which story is true. It just repeats the guess back to you dressed as a fact.
The honest way to use forward P/E is as a conversation starter, not a verdict. Ask why the forecast looks the way it does, who made it, and what could knock it off course, before you let one number decide where your money goes.
A company's share price is ₦150 and analysts forecast earnings of ₦10 per share for the coming year. Forward P/E equals 150 divided by 10, which is 15. If actual earnings come in at ₦8 instead, the real P/E once results are out would rise to 18.75, even though the share price never moved.
Questions people ask
Is a lower forward P/E always a better buy?
Not always. A low forward P/E can mean the share is undervalued, but it can also mean the market doubts the earnings forecast will actually be met. Always ask what is behind the number before treating it as a bargain signal.
Where do the earnings forecasts in forward P/E come from?
They usually come from equity analysts at banks and research firms who study the company's business, guidance and industry trends, then publish an estimate. Different analysts can forecast different figures, so the forward P/E you see is often an average of several guesses.
How is forward P/E different from trailing P/E?
Trailing P/E uses earnings the company has already reported, so it is based on fact. Forward P/E uses earnings that have not happened yet, so it is based on forecast. Comparing both together often gives a fuller consider than relying on either alone.
