Growth Investing and Finding The High Flyers

8.5 Revenue Growth and Growth Investing: The Rhythm of Compounding Success

“The best way to measure your investing success is not by whether you’re beating the market but by whether you’ve put in place a financial plan and a behavioral discipline that are likely to get you where you want to go.” — Benjamin Graham

If value investing is like composing a great symphony—built on structure, patience, and harmony—then growth investing is jazz. It’s dynamic, full of improvisation, and rewards those who can spot the rising rhythm before the rest of the world catches on.

Growth investing is centered on one core idea: companies that expand revenue at high rates will eventually dominate their industries and reward investors handsomely. But just as not all jazz sounds good, not all revenue growth leads to profits. The great challenge for investors is distinguishing between true compounding machines and companies that grow without real economic value.

Step 1: The Essence of Growth Investing – Revenue as the Foundation

“Someone is sitting in the shade today because someone planted a tree a long time ago.” — Warren Buffett

At the heart of every great growth stock is revenue growth—the expansion of sales over time. Revenue is the fuel that powers earnings, reinvestment, and long-term compounding. Without it, even the best management teams and most innovative products will eventually hit a ceiling.

But here’s the key: revenue growth must translate into actual economic value. A business can increase sales dramatically but still fail to create wealth for shareholders if margins collapse or debt balloons.

Investor’s Rule of Thumb:

Revenue growth above 10-15% per year is a strong signal for a growing company.
Above 30% and you may be looking at a potential compounding machine—if fundamentals support it.

🔎 Real-World Example:

In the early 2000s, Amazon grew revenue at 30%+ per year, but skeptics doubted profitability.
However, Amazon’s revenue growth eventually scaled into immense profits, rewarding patient investors.
Compare this to WeWork, which had impressive revenue growth but no clear path to profitability—leading to its collapse.

Lesson? Revenue growth is a necessary but insufficient condition for a great investment.

Step 2: The Growth Investor’s Checklist – What Makes a Growth Stock Work?

Before we buy into growth, we must determine whether we’re looking at a compounder or a money-burning illusion.

1. Revenue Growth Rate – How Fast Is the Company Growing?

Growth stocks typically expand 15% or more per year.
Hypergrowth stocks expand 30%+ per year, but require strong fundamentals.

🔎 Investor’s Rule of Thumb:

If growth is slowing dramatically, the market may reprice the stock lower.
If growth is accelerating, it may signal a breakout investment opportunity.

2. Gross Margins – Can Growth Turn into Profits?

Gross margin measures how much profit remains after direct costs.
High gross margins (above 50%) indicate a company with pricing power.
Low gross margins (below 30%) may mean the company struggles to convert sales into profit.

🔎 Why It Matters:

Tesla’s revenue growth was exciting, but it wasn’t until gross margins improved that the market rewarded it with higher valuations.
Uber had strong revenue growth but weak gross margins for years, making profitability a challenge.

Lesson? If revenue growth comes at the expense of profits, be skeptical.

3. Free Cash Flow (FCF) – Is the Business Self-Sustaining?

True compounders generate positive free cash flow even as they grow.
If a company burns cash indefinitely, it may need constant fundraising, diluting shareholders.

🔎 Investor’s Rule of Thumb:

If a company’s free cash flow grows alongside revenue, it’s a strong signal of sustainable growth.
If FCF remains negative for too long, it suggests growth is being funded artificially.

4. Total Addressable Market (TAM) – How Big Can the Business Get?

A company growing fast in a small market will eventually hit a wall.
Great growth stocks operate in massive and expanding markets.

🔎 Investor’s Rule of Thumb:

If TAM is under $10 billion, growth may be limited.
If TAM is $100 billion+, the company has room for many years of expansion.

Example:

Google grew exponentially because search and digital advertising was a $1 trillion opportunity.
Peloton had strong early growth, but its market was narrow and saturated quickly.

Lesson? Growth needs room to run.

Step 3: When Growth Goes Wrong – The Dangers of Overpaying

“The stock market is filled with individuals who know the price of everything, but the value of nothing.” — Philip Fisher

The biggest mistake growth investors make is overpaying for future expectations.

A company growing at 30% per year may seem like a bargain—until it slows to 10% and the stock collapses.
Valuation matters—even for growth stocks.

Price-to-Sales Ratio (P/S) – The Sanity Check

Formula: P/S = Market Cap ÷ Revenue
Meaning: How much are investors paying per dollar of sales?

🔎 Investor’s Rule of Thumb:

A P/S above 10 suggests high expectations—the company must continue rapid growth.
A P/S below 3-5 may indicate a reasonable valuation.

Example:

In 2021, Zoom traded at P/S of 50—investors assumed unstoppable growth.
When growth slowed, the stock collapsed by over 75%.

Lesson? Growth investing is about finding fast-growing companies at reasonable prices—not buying at any cost.

Step 4: The Buffett-Munger Perspective – Growth AND Value Together

“Great investing requires a lot of delayed gratification.” — Charlie Munger

While Warren Buffett is often associated with value investing, his best investments have been growth stocks bought at reasonable prices.

Coca-Cola (1980s): Buffett bought because of strong revenue growth and pricing power.
Apple (2016): Buffett saw consistent revenue growth, high margins, and strong cash flow, making it a growth stock with value characteristics.

Buffett’s best advice? Pay a fair price for a great business rather than a great price for a mediocre business.

Final Takeaways: The Growth Investor’s Compass

Revenue Growth Is the Foundation – But only if it translates into profits.
Margins Matter – High revenue growth with low margins is a red flag.
Cash Flow Is King – True growth companies generate real cash, not just hype.
TAM Determines Potential – If the market is small, future growth is capped.
Avoid Overpaying – Growth stocks must still be bought at reasonable prices.

Final Thought: Investing as a Symphony, Not a Solo Performance

Growth investing is not just about speed—it’s about endurance. The best businesses grow not just for a few years, but for decades, compounding wealth for patient investors.

Or, as Buffett would say:

“Time is the friend of the wonderful company, the enemy of the mediocre.”

So, the real question isn’t how fast a company is growing today, but how long it can keep playing the right notes in the market’s great symphony.
