Why Fast-Growing Companies Can Still Look Expensive

Finding a fast-growing company seems like an obvious starting point for an investor. Revenue is expanding, new customers are arriving, products are gaining adoption and management sees opportunities to enter additional markets. If the business keeps getting larger, shouldn't its stock become more valuable as well?

The missing variable is price.

The stock market does not offer successful companies in isolation. It attaches a valuation to them, and that valuation reflects assumptions about what the business may achieve in the future. A company can therefore have excellent growth prospects while its shares already incorporate a very optimistic version of those prospects.

Axon Enterprise illustrates the dilemma well. Rapid revenue growth, expanding recurring software sales and a broader technology ecosystem can all strengthen the business case. For an investor, however, there is a second question: how much future success is already being paid for today?

Growth Deserves a Premium — Up to a Point

Investors are often willing to assign higher valuations to companies that can expand quickly for a long time.

There is a logical reason for this. If two businesses earn the same amount today but one has a realistic path to become several times larger, their future cash-generating potential is different. The faster-growing company may therefore deserve a higher valuation multiple.

This is why ratios such as price-to-earnings or price-to-sales cannot always be interpreted in isolation. A high multiple may reflect expectations for rapid expansion rather than simple market enthusiasm.

Axon entered 2026 after four consecutive years of annual revenue growth above 30%. Management has also outlined a long-term objective of reaching approximately $6 billion in annual revenue by 2028.

Performance of that kind gives investors reasons to think beyond the current year's earnings.

But the more investors pay for expected growth, the more important it becomes for that growth to actually arrive.

A High Valuation Raises the Bar

Suppose the market expects a company to increase revenue by 30% annually. If the business delivers 30%, management has executed extremely well — but investors have also received roughly what they were already paying for.

If growth reaches 40%, expectations may rise further.

If it slows to 20%, the business is still expanding rapidly, but the valuation may need to adjust because the original assumptions no longer fit as well.

This is the difficult feature of growth stocks: a company does not necessarily have to become bad for its shares to disappoint. It may simply become less exceptional than the price assumed.

Axon's recent performance demonstrates why expectations can become demanding. In the first quarter of 2026, revenue increased 34% year over year, while management raised its full-year growth outlook to 30–32%.

Strong results can support confidence in the growth story. They can also establish a higher benchmark for the next quarter.

Valuation Can Change Without the Business Shrinking

This leads to a concept known as multiple compression.

Imagine a company earning $5 per share while investors are willing to value it at 50 times earnings. The resulting share price would be $250.

Now imagine earnings increase to $6. The company has become more profitable. But if investors become willing to pay only 35 times earnings, the implied price falls to $210.

Nothing in this example requires the business to shrink. Earnings actually increased by 20%.

What changed was the price investors were prepared to pay for each dollar of earnings.

Interest rates, changing perceptions of risk, slower expected growth or a general shift in market sentiment can all influence valuation multiples. That is why stock performance and operating performance sometimes move in different directions.

For highly valued growth companies, this relationship can be particularly important because a larger portion of the valuation may depend on profits expected many years into the future.

A Great Company and a Great Investment Are Different Questions

This distinction does not mean investors should avoid companies with high valuations. Nor does a low valuation automatically make a stock attractive.

It means business quality and investment price need to be considered separately.

An investor studying Axon might reasonably conclude that the company has attractive products, recurring customer relationships and substantial opportunities for future expansion. The next step is not simply to repeat those positives. It is to ask what assumptions about growth, profitability and execution are necessary to justify the market valuation.

That changes the investment question.

Instead of asking only “How good can this company become?”, the investor also asks “How good does it already need to become for today's price to make sense?”

The distinction is subtle but important. Stock prices represent a meeting point between business performance and expectations. The stronger the expectations become, the less room there may be for ordinary results.

A fast-growing company can therefore remain an excellent business while its stock looks expensive. There is no contradiction between those statements.

One describes the company. The other describes the price investors are being asked to pay for its future.
