Why the stock price of a company fall after good results?

The Company Grew 25% a Year. So Why Did You Make Only 4% Returns? Imagine getting the business call absolutely right. The company grows profits at 25% a year. Management executes well. There is no major disruption to the business. Three years later, earnings have nearly doubled.

You should have made fantastic returns, right?

Not necessarily.

You could get almost everything right about the company and still make only 4–5% annual returns from the stock.

The reason is something investors sometimes underestimate: valuation.

A stock’s return is not determined by earnings growth alone. It is also influenced by how much the market is willing to pay for those earnings. And when these two forces move in opposite directions, strong business performance can produce surprisingly mediocre investment returns.

The 25% Growth Trap

There is a common assumption in investing:

“If the company’s profits grow at 25–30% CAGR, the stock should also compound at roughly 25–30%.”

It sounds logical.

Over sufficiently long periods, earnings growth is certainly one of the most important drivers of stock prices. But over three, five or even more years, changes in valuation multiples can dramatically alter your actual returns.

Let’s understand this with a simple example.

Suppose a company currently earns an EPS of ₹10.

The market is excited about its prospects and values the company at 60 times earnings.

So:

₹10 EPS × 60 P/E = ₹600 share price

You buy the stock at ₹600.

Now assume your business thesis turns out to be correct. The company performs well and grows its earnings at 25% CAGR for the next three years.

Its EPS increases from ₹10 to roughly ₹19.5.

That is excellent performance. Earnings have almost doubled in just three years.

There is nothing fundamentally wrong with the business.

But there is another side to the equation.

What Happens If the P/E Falls?

When you bought the stock, investors were willing to pay 60 times earnings for it.

Three years later, perhaps the excitement has cooled. The company is still doing well, but the market decides that a 60 P/E was simply too expensive.

The stock is now valued at 35 times earnings.

Your calculation becomes:

₹19.5 EPS × 35 P/E = approximately ₹683

Think about what just happened.

You bought at ₹600.

Three years later, after the company’s earnings nearly doubled, the stock is worth only about ₹683.

Your investment has produced a CAGR of roughly 4.4%.

The company delivered.

The earnings thesis worked.

Yet your investment return was disappointing.

Where Did All That Growth Go?

Two powerful forces were acting on the stock simultaneously.

Earnings growth: EPS increased from ₹10 to about ₹19.5 — an increase of roughly 95%.

Valuation contraction: P/E fell from 60 to 35 — a decline of about 42%.

The huge increase in earnings was largely offset by the fall in the valuation multiple.

This is known as P/E de-rating or multiple compression.

And it explains why saying, “This company can grow earnings at 25% for the next three years,” is not enough to determine whether the stock is attractive.

There is another question that matters just as much:

How much am I paying today for that growth?

Now Consider the Opposite Situation

Let’s take another company.

It also earns ₹10 per share, but the market currently values it at only 20 times earnings.

Its share price is therefore:

₹10 EPS × 20 P/E = ₹200

This company doesn’t grow as quickly as our first company.

Instead of 25%, suppose earnings compound at around 18% annually.

After three years, EPS reaches roughly ₹16.4.

Earnings have increased by about 64%.

Clearly, the first company was the faster-growing business.

But something interesting happens here.

The second company executes consistently. Return ratios improve. Investors gain confidence in the durability and quality of the business.

As a result, the market gradually decides that the company deserves a higher valuation.

Its P/E expands from 20 to 30.

Now calculate the share price:

₹16.4 EPS × 30 P/E = ₹492

The stock that started at ₹200 is now worth approximately ₹492.

The company grew earnings slower than our first company, yet its shareholders made dramatically better returns.

Why?

Because this time both forces worked in the investor’s favour.

Earnings increased, and the valuation multiple expanded.

Business Growth and Stock Returns Are Not the Same Thing

This distinction is incredibly important.

When someone says:

“Company ki earnings 25% grow karengi next 3 years mein.”

That’s great.

But the next question should be:

“Achha hai… par us growth ke liye aaj kitna price de rahe ho?”

Predicting earnings growth is only one part of the investment equation.

You also need to think about the valuation you are paying for that growth.

A fantastic business does not automatically become a fantastic investment at every price.

High Valuations Leave Little Room for Mistakes

Suppose a company is expected to grow earnings at 25% annually and is already trading at 60–70 times earnings.

What exactly is that valuation telling you?

It may be telling you that investors already expect years of excellent execution.

The market may be pricing in 25% growth with almost no bad quarters, no meaningful margin pressure, no working-capital surprises, no major competitive threat and no reduction in management guidance.

That’s a lot of expectations packed into one share price.

And expectations matter because stocks don’t necessarily fall when businesses become bad.

Sometimes they fall because a good business becomes slightly less good than investors expected.

A company can still report 20% earnings growth and disappoint the market if investors had already priced in 30%.

When expectations are extremely high, even a small disappointment can cause the valuation multiple to fall rapidly.

A 60 P/E becoming 45 P/E represents a 25% valuation contraction — even before considering what happened to earnings.

“Results Were Good. Why Did the Stock Fall?”

Indian investors have seen this situation many times.

A company announces apparently good quarterly numbers.

Revenue increased.

Profit increased.

Margins look reasonable.

Yet the stock falls 5%, 10% or sometimes even more.

People naturally ask:

“Results toh achhe the, stock gira kyun?”

Sometimes there is nothing particularly wrong with the results.

The problem is what the share price was already expecting before those results arrived.

If the market had already priced the stock for exceptional growth, merely delivering “good” numbers might not be enough.

Markets continuously compare reality with expectations, not simply this year’s profits with last year’s profits.

That distinction becomes especially important when investing in expensive growth stocks.

The Price You Pay Matters

There is a useful lesson hidden inside these examples.

A great company bought at an excessive valuation can leave an investor waiting for years while earnings catch up with the share price.

Meanwhile, a slightly slower-growing company purchased at a sensible valuation can sometimes generate excellent returns when improving fundamentals are accompanied by a valuation re-rating.

Of course, this doesn’t mean investors should automatically buy low-P/E stocks or avoid high-P/E companies.

Some exceptional businesses genuinely deserve premium valuations because of their growth runway, competitive advantages, capital efficiency and quality of management.

Likewise, many stocks trade cheaply for very good reasons.

The point is simply that growth cannot be analysed independently of valuation.

The Simple Equation Investors Should Remember

At a basic level, you can think about stock returns as being influenced by two major components:

Earnings growth + change in valuation multiple = potential stock return

It isn’t a perfect forecasting formula. Dividends, dilution, buybacks and several other factors can also affect shareholder returns.

But as a mental model, it is extremely useful.

If earnings grow and the valuation remains roughly unchanged, the stock can broadly follow earnings over time.

If earnings grow but the valuation contracts sharply, shareholder returns can significantly lag business growth.

And if earnings grow while the valuation also expands, the combination can produce exceptional returns.

That is why your starting valuation matters enormously.

Conclusion: Don’t Just Ask How Fast the Company Will Grow

Finding businesses capable of compounding earnings at 20%, 25% or 30% is undoubtedly important.

But identifying a great business is only half the job.

The other half is deciding what price you are willing to pay for it.

A company can execute perfectly and still deliver mediocre stock returns if your purchase price already reflected years of exceptional growth.

Conversely, a somewhat slower-growing business purchased when expectations are reasonable can generate surprisingly strong returns when earnings growth and valuation expansion work together.

So the next time you hear:

“This company can grow profits at 25% CAGR for the next three years.”

Don’t stop there.

Ask one more question:

“How much of that 25% growth am I already paying for today?”

Because in investing, what you buy matters — but the price you pay for it matters just as much.
