Key Takeaways
- ServiceNow shares fell nearly 18% after weak subscription growth guidance overshadowed strong AI demand, a clear example of how growth stocks can be punished when expectations are high.
- Growth vs value investing is about what you pay for future earnings, not about whether a company is good or bad. The labels describe styles, and styles carry different risks.
- A cheap stock is not automatically a bargain and a fast-growing company is not automatically a good investment. Price relative to expectations is what matters.
A strong AI story, an 18% fall
ServiceNow stock plunged nearly 18% after the company reported third quarter results that disappointed investors and gave weak guidance for subscription growth. The drop came even though demand for the company's AI products was described as strong. Strong AI demand was not enough to offset the disappointing results and the weak guidance.
A candidate who thinks only in terms of good companies and bad companies will find this move confusing. A candidate who thinks in terms of price and expectations has a better frame for it.
We should be careful about what we claim here. The source says disappointing earnings and weak subscription growth guidance overshadowed strong AI demand, and we go no further than that. What we can say is that the market reacted sharply to a change in the growth outlook, and that is the central risk of owning growth stocks.
What the labels actually describe
In plain terms, a growth stock is one where investors expect earnings or revenue to expand faster than the market average. Investors are usually willing to pay a higher price relative to current earnings, book value, or sales because they are buying the future. A value stock is one that trades at a low price relative to those same measures. Investors buy it because they think the market is too pessimistic, or because the current price already offers a cushion.
These are styles, meaning broad approaches to selecting equities. They are often measured with simple valuation ratios such as price to earnings and price to book. Growth portfolios tend to sit on the high end of those ratios and value portfolios on the low end. The exam asks you to understand what those ratios say and what they leave out. This article will not walk through the mechanics, because the point is the intuition.
A company can grow quickly and still disappoint if it grows more slowly than investors had hoped. That may be the shape of the ServiceNow story: strong AI demand, but weak subscription growth guidance.
Why expectations matter more than quality
It is tempting to believe that buying great businesses guarantees good returns. It does not. Returns come from the difference between what the market expected when you bought and what actually happened afterwards. A great company bought at a price that assumes perfection can deliver poor results. An ordinary company bought at a price that assumes failure can deliver good ones.
This is why growth stocks tend to be more sensitive to news about the growth rate itself. When a large share of a company's value sits in cash flows far in the future, even a small downgrade to the growth path can cause a large repricing. Value stocks have their own sensitivities, but their prices lean more on current assets and earnings, which can make them less dependent on distant forecasts.
The flip side deserves equal attention. One of the stories in the news feed this week described the low multiples of value stocks as offering a margin of safety that growth stocks rarely provide, while also noting that the real challenge is working out whether the cheap assets are truly undervalued. That caveat is important. A low multiple can reflect a business in permanent decline. Candidates meet this idea as a value trap: the stock looks cheap because the future is genuinely poor, not because the market is wrong.
Where the labels mislead
Treating growth and value as two sealed boxes is a common beginner mistake. Many companies sit between them, and investors who blend the two approaches are sometimes described as seeking growth at a reasonable price. A stock with a modest multiple and strong projected growth does not fit neatly in either camp, and a style label can change as a company matures or as its share price moves.
Labels also depend on who is applying them. Index providers and fund managers use different rules, so the same stock can be called growth by one and value by another. That matters when you compare a fund's performance with a benchmark. If the style of the benchmark does not match the style of the manager, the comparison tells you less than it seems to.
Finally, style leadership rotates. Periods favour growth, then value, and the reasons are often tied to interest rates, economic conditions, and shifts in sentiment. No label guarantees outperformance, and a diversified investor often holds both on purpose.
What to watch, and how to test yourself
When you read the next earnings reaction, ask three questions. What growth rate was the price assuming? Did guidance move that assumption up or down? And is the stock being judged mainly on future cash flows or on assets and earnings already in hand? Those questions turn a headline into a CFA style analysis, and they work on any company.

FAQ
What is the difference between growth and value investing?
Growth investing focuses on companies expected to grow earnings or revenue faster than average, often at higher valuation multiples. Value investing focuses on stocks that trade at low prices relative to measures like earnings or book value, on the view that the market is too pessimistic.
Why can a growth stock fall sharply even when demand is strong?
A high price usually reflects high growth expectations. If guidance suggests growth will be slower than expected, the stock can be repriced downward even when the underlying business is healthy. ServiceNow's drop of nearly 18% despite strong AI demand is an example of this dynamic.
Is a low valuation multiple always a sign of a bargain?
No. A low multiple can mean the market is too gloomy, but it can also reflect real problems. Stocks that look cheap for good reason are often called value traps, so analysts must judge whether the discount is justified.
Do growth vs value investing styles matter for the CFA Level 1 exam?
Yes. Candidates need to understand how equity styles are described, what valuation ratios say about them, and why style labels can differ between managers and benchmarks. The focus is on concepts and interpretation rather than headlines.
