Forward Multiple
A forward multiple relates a company's current market value to an expected future figure, usually next year's earnings or revenue. It is the most common metric for judging whether a stock is expensively or cheaply valued – especially for fast-growing tech and AI companies.
Anyone who buys a stock buys a share of a company. The question is always: is the price reasonable? To answer that, you divide the price by something the company actually generates – for example, its profit. The result is called a multiple, meaning a multiplier value. A forward multiple does not use last year’s profit for this, but the profit that experts expect for the coming twelve months. “Forward” here simply means: looking ahead.
Why investors prefer to look ahead rather than back
A stock’s price is driven by the future, not the past. Nobody pays money today for profits that flowed two years ago. What is being paid for is the claim to everything the company will earn from now on. That is exactly why looking backward is often misleading.
This becomes especially clear with young technology companies. An AI start-up may have posted losses last year and still be worth billions. If you calculate using past profit, no meaningful number comes out at all. If you calculate using the expected profit in two years, the valuation suddenly tells a coherent story.
The forward multiple also makes different companies comparable. A chipmaker and a software provider have very different sizes and revenues. With the multiple, only the ratio of price to expected performance matters. This makes it possible to say in one sentence which of the two stocks the market is pricing more expensively.
The math behind the number
The basic formula is simple: you divide the share price by the expected earnings per share. If a share costs 200 euros and the company is expected to earn 10 euros per share next year, the forward multiple is 20. Colloquially, one then says: the stock is trading at twenty times its earnings.
Instead of profit, other figures can also be used. For companies without profit, expected revenue is often used instead. This is then called the revenue multiple. A software company trading at fifteen times its annual revenue is considered highly valued, while a carmaker trading at one times its revenue is considered low. Which reference figure makes sense therefore depends heavily on the industry.
The crucial catch lies in the word “expected”. The future figures come from analysts, meaning experts at banks and research firms. These are estimates, not facts. If actual profit turns out lower, the stock was, in hindsight, much more expensive than thought. A forward multiple is therefore only ever as reliable as the forecast it is based on.
From quarterly results to bubble debates
This metric appears in financial news almost daily. Sentences like “The stock is trading at 30 times expected earnings” are standard. The phrase “forward P/E” is also commonly seen, the English abbreviation for the expected price-to-earnings ratio. It always refers to the same ratio of price to future figure.
Around the AI boom, this metric has taken on special significance. When critics warn of a bubble, they usually point to unusually high forward multiples at chip and cloud companies. Defenders counter that expected profits are still rising sharply, causing the number to shrink on its own. The debate therefore is not just about the price alone, but about the credibility of the forecast.
A common mistake is to automatically consider a low multiple a bargain. Often it is low because the market expects declining profits. Conversely, a high multiple can be justified if a company grows strongly for years. The number does not replace analysis – it merely summarizes what the market currently expects.
