You’ve spent sixteen posts learning how to value a business and protect yourself from overpaying. Now comes the second act — finding businesses that grow faster than everyone else.
In The Rules series, you learned discipline. Buy and hold. Let compounding run. Minimize friction.
In the Intrinsic Value series, you learned how to estimate what a business is actually worth — the free cash flow, the discount rate, the margin of safety.
Those two series taught you to think like a value investor: find a good business, estimate its worth, buy it at a discount, and wait.
That’s a complete investing approach on its own. It works. But it’s not the only approach — and it’s not always the right one for every company.
This series is about something different: growth investing. And the first thing we need to do is get clear on what that actually means — because the term gets used loosely, and the confusion costs people money.
Growth Investing vs. Value Investing — What’s the Real Difference?
Here’s how people often describe it: value investors are cheap, growth investors pay up.
That’s not wrong, but it misses the deeper distinction.
Value investors are looking for businesses whose stock price is below their estimate of intrinsic value — the present value of the cash the business will generate. The discount to intrinsic value is the margin of safety. You’ve seen this model in detail. You built it. The key assumption is that the market has temporarily mispriced a business, and that over time, the price will converge toward true value.
Growth investors are looking for something different. They are looking for businesses expanding their revenue and earnings faster than the market — faster than the economy, faster than competitors, faster than most other investments. The bet is not that the stock is cheap today. The bet is that the business will be so much larger tomorrow that today’s price, which looks high, will look like a bargain in hindsight.
Both approaches work. They’re just answering different questions.
Value investing asks: What is this business worth, and am I paying less than that?
Growth investing asks: Is this business expanding fast enough, and consistently enough, that holding it over time will compound my money at an above-average rate?
The two approaches are not opposites. They’re just looking at different parts of the same investment. Some of the best growth investments are also cheap by value measures. Some of the worst are expensive by both. The distinction is really about what you’re emphasizing — the current price discount, or the future growth trajectory.
What a Growth Stock Actually Looks Like
Not every company growing its revenue qualifies. Growth investing, done carefully, means looking for a specific pattern. A genuine growth stock has several characteristics.
Sustained revenue growth. The top line — total revenue — is expanding at a pace well above average, year after year. Not just one or two good years. Not a flash of growth followed by flatness. Consistent expansion over five years, ten years, through different market conditions.
Earnings growing at least as fast as revenue. Revenue growth is easy to fake — a company can buy it by acquiring other businesses, cutting prices, or spending heavily. What matters is whether the bottom line — earnings — is growing at the same pace or faster. That shows the growth is real and profitable, not just purchased.
Reinvestment into the business. Growth companies do not hand out their profits as dividends. They reinvest. They’re building new products, expanding into new markets, hiring, developing technology. You will often see lower dividend payments — or none at all — from genuine growth companies. That’s not a flaw. It’s evidence that management sees better uses for the capital than returning it to shareholders at this stage.
Higher P/E multiples — and why that can be legitimate. You know that the P/E ratio — price divided by earnings per share — is a measure of how much investors are paying for each dollar of earnings. A P/E of 20 means investors are paying $20 for every $1 the company earns annually.
Growth stocks often trade at high P/E ratios. That surprises some readers — doesn’t that mean you’re overpaying?
Not necessarily. And here’s why.
The P/E ratio is based on current earnings. If a company is growing its earnings at 20% per year, the earnings in three years will be roughly double what they are today. Investors are paying today’s high price anticipating tomorrow’s much larger earnings stream. If the growth materializes, the multiple was justified. If it doesn’t, you overpaid. That tension is what makes growth investing hard.
Why Growth Investing Carries More Risk
When you buy a stock at a 40% discount to intrinsic value, you have a cushion. The business can disappoint your projections somewhat, and you still did fine because you didn’t overpay to begin with. That’s the whole point of margin of safety.
When you buy a growth stock at a high P/E multiple, you have no such cushion. You’re paying for the future. If that future doesn’t arrive — if growth slows, if competition shows up, if the company stumbles in a critical year — the stock can fall hard. Not because the business failed, but because the growth investors expected didn’t materialize.
This is sometimes called multiple compression. A company trading at P/E 35 because the market expects 20% annual growth can drop to P/E 18 if that growth rate slips to 8%. The business is still growing. Earnings are still going up. But the valuation collapses because the premium built on high expectations evaporates.
Growth investing requires you to be right about the future more consistently than value investing does. That’s not impossible — but it means more positions will disappoint, and the positions that disappoint will often disappoint dramatically.
The other risk is timing. Growth companies require patience. If you buy a genuine long-term grower but sell during a bad quarter because the stock pulled back, you’ve paid the growth investor’s higher entry price without capturing the growth investor’s long-term payoff. That’s the worst of both worlds.
The upside, when you’re right, is also larger. A business that grows earnings at 15% annually for ten years has grown those earnings four times over. Owning that at the start, even at a premium, produces outstanding long-run returns. The risk and the reward are two sides of the same coin.
A Systematic Way to Narrow the Field
Given these risks, the obvious question is: how do you find growth companies likely to deliver on their promise, and screen out the ones trading on hype?
That’s exactly what Part 2 will cover in detail.
The approach I use runs every candidate through six sequential gates. Each gate is a hard pass or fail — no averaging, no partial credit. A company must clear every gate to make it onto the candidate list.
Here’s a brief preview of the territory Part 2 will map:
The first two gates focus on price and debt — asking whether the stock is trading at a reasonable multiple and whether the company is conservatively financed. Growth paid for with borrowed money is fragile growth.
The next two gates measure the growth itself — not just recently, but over the last five and ten years. Has the company actually grown revenue and earnings at a pace that justifies calling it a growth stock? Both the short run and the long run matter.
The final two gates go deeper into quality — asking whether the business is genuinely creating value for shareholders, and whether it has delivered consistent profitability without a single losing quarter in five years.
Companies that clear all six gates are rare. That’s the point. Part 2 will walk through each gate, explain why it’s there, and show you how to think about what it’s measuring.
A Note to Luca and Lili
By the time you read this, you’ll have been through sixteen posts on the rules and the valuation model. You know more than most investors twice your age.
Here’s what I want you to take from this post before we go any further.
Value investing and growth investing are not competing religions. They’re two lenses. Sometimes the same stock looks attractive through both. Sometimes a company passes every growth screen and still carries too high a price for a value investor to feel comfortable — and that’s okay. You get to decide which framework fits the opportunity.
What I want you to be careful about is the story. Growth investing attracts a lot of exciting stories. Companies changing the world. Disrupting industries. “This is the future.” Stories feel compelling. They’re also often how people end up paying 80 times earnings for a company whose growth turns out to be ordinary.
The gates in Part 2 exist precisely to cut through the story. They ask whether the numbers confirm the narrative. Most exciting stories do not pass all six gates. A few do — and those are the ones worth a serious look.
Be skeptical of excitement. Be curious about the numbers. They usually tell different stories.

The One-Sentence Summary
Growth investing means paying a premium for companies expanding their revenue and earnings at exceptional rates — which can produce outstanding long-run returns, but only if the growth actually materializes, which means the risk of being wrong is higher than in value investing.
Next: Part 2 — The Six Gates. We’ll walk through each screening criterion in detail: what it measures, why it matters, and how to calculate it from a company’s real financial statements.
