Anyone who buys a share and expects a return first thinks of profit growth. The company earns more, the share price rises. This logic is correct, but it only explains part of the reality.
A second lever often has just as strong an effect: multiple expansion. In simple terms, the share price can be broken down into profit multiplied by the multiple. Returns are therefore generated either by rising profits, by a rising multiple, or by both at the same time. The multiple does not rise because more is earned, but because the market is prepared to pay more per unit of profit.
Three factors regularly drive this.
1. change of narrative. If a company is reclassified by the market, the willingness to value it changes.
A cyclical industrial group suddenly becomes a platform. A hardware manufacturer becomes a software company. The decisive factor here is not the narrative alone, but that the market expects a structurally higher quality of cash flows: more growth, better margins, less cyclicality. $MSFT (+0.76%) is perhaps the cleanest example. Under Steve Ballmer, Microsoft was seen as a stagnating Windows company with a P/E ratio of around 10 to 12. Satya Nadella repositioned the company as a cloud platform. The multiple multiplied, but not blindly: Azure growth and margin improvement provided visible confirmation early on. Story and fundamentals picked up together.
2. interest rates. Lower interest rates increase the present value of future profits.
More precisely: the total discount rate, i.e. the risk-free interest rate plus the risk premium on equity, is decisive. Growth stocks react more strongly to this than the market average because their profits lie further in the future. The longer the term of the expected cash flows, the greater the interest rate effect on the valuation. 2022 was a real-time test of this: When the Fed aggressively raised interest rates, highly valued growth stocks such as $PYPL (+2.1%) or $SHOP (+3.35%) fell massively in value. The discount rate effect was dominant, even if operational disappointments were also a factor in both cases.
3. risk perception. When the market perceives a company as safer, the perceived uncertainty of cash flows decreases.
Lower equity costs justify a higher multiple without anything having changed operationally. At $AMZN (+0.78%) this was observed when AWS was reported separately for the first time. Investors recognized that there was a highly profitable cloud segment behind the low-margin trading business. The Group's risk profile was reassessed. The multiple increased.
$NVDA (+1.9%) illustrates multiple expansion better than any textbook example, but with an important nuance. At the end of 2022, Nvidia was trading at a forward P/E of roughly 30 to 40. Then came ChatGPT. Suddenly, investors no longer saw Nvidia as a graphics card manufacturer, but as an infrastructure provider for artificial intelligence. The multiple climbed sharply.
At the same time, earnings estimates exploded. $NVDA (+1.9%) This is therefore not an example of pure multiple run-up, but of the ideal case: narrative change, earnings revisions and multiple expansion occurred simultaneously. All three levers pulled together.
$META (+1.93%) shows the other side. In 2022, the multiple collapsed from around 25 to less than 10. The market no longer believed in the metaverse, feared a structural decline in the advertising business and saw billions disappear into reality labs. Profits fell and the multiple shrank. Double compression.
What followed was re-rating in its purest form. Mark Zuckerberg announced the "Year of Efficiency". Costs were massively reduced and the company reprioritized. Profits recovered quickly. The multiple rose from below 10 to over 25.
Who $META (+1.93%) bought at the end of 2022 or beginning of 2023 caught a rarely clean pattern: profit recovery plus re-rating. Both levers at the same time.
This leads to an uncomfortable truth. The multiple itself is not an independent force, but a function of growth expectations, interest rates and perceived cash flow quality. What cannot be reliably predicted is not the multiple, but how expectations and narratives shift. The market can read the same quarterly figures as confirmation or disappointment, depending on what it has previously priced in.
What you can do is recognize when the multiple is already pricing in a lot of optimism and assess whether the narrative supports it. A P/E ratio of 70 for$NVDA (+1.9%) needs sustained high earnings growth to remain justified. If the multiple compresses to 40 without a drop in earnings, the revaluation alone creates a significant headwind of over 40 percent. This has not happened. $NVDA (+1.9%) has grown into the valuation.
In my view, multiple expansion is more of an observation than a strategy. You can see it more clearly in the rear-view mirror than through the windshield.
The next article turns the question around: What happens when the multiple barely moves? When is pure earnings growth enough to deliver exceptional returns? $AMZN (+0.78%) has shown over two decades that this is possible.
