Growth Investing Strategy

Own the companies expanding faster than the market, and let years of compounding revenue and earnings do the heavy lifting.

Understanding Growth Investing

What is Growth Investing?

Growth investing focuses on companies expected to grow their revenue and earnings significantly faster than the overall market. Rather than buying cheap, growth investors pay up for businesses with large addressable markets, durable competitive advantages and the ability to reinvest profits at high rates of return — betting that rapid compounding will justify today's higher price.

How Does It Work?

The investor identifies companies early in a long growth runway — often in technology, healthcare or other innovative sectors — and holds them as the business scales. Returns come primarily from earnings growth compounding over many years, and secondarily from the market awarding a higher valuation as that growth proves durable.

The Core Ideas

1. A Large Runway

Growth needs somewhere to go:

  • A big and expanding total addressable market (TAM).
  • Low current penetration, leaving years of room to grow.
  • Secular tailwinds — structural shifts the company rides rather than fights.

2. Reinvestment & Returns on Capital

The engine of compounding:

  • The company can deploy profits into growth at high returns on invested capital.
  • Each dollar reinvested produces more future earnings than it would as a dividend.
  • A widening competitive moat protects those returns from competitors.

3. Paying Up — Carefully

Growth rarely comes cheap:

  • High P/E and P/S multiples are common and can be justified by future growth.
  • The risk is overpaying — if growth slows, rich valuations contract sharply.
  • The PEG ratio helps weigh the multiple against the growth rate.

What to Look For

How to Apply It

  1. Find the trend, then the leaders

    Start from a durable secular shift, then identify the companies best positioned to capture it.

  2. Verify the growth is real

    Check that revenue, margins and cash flow are trending up — not just the narrative.

  3. Mind the entry valuation

    Use the PEG ratio and scenarios to avoid overpaying for growth that may not materialize.

  4. Hold winners, cut broken theses

    Let compounding run, but sell when the growth thesis clearly breaks rather than on price alone.

A Worked Example

Sizing Up a Growth Candidate

  1. A software company grows revenue 30%+ a year into a large, under-penetrated market.
  2. Gross margins are high and expanding, and the customer base keeps spending more over time.
  3. The stock trades at a rich sales multiple — but the PEG looks reasonable against the growth rate.
  4. You confirm returns on capital and a widening moat, then build a position you can hold for years.
  5. You re-underwrite each quarter: as long as growth and unit economics hold, you stay invested.

Best Practices

  • 🚀
    Focus on Durable Growth

    A long runway and a real moat matter more than one explosive quarter.

  • 💸
    Valuation Still Matters

    Even a great company can be a poor investment if you pay too much. Weigh price against growth.

  • 🎢
    Expect Volatility

    Growth stocks swing hard. Size positions so you can hold through the drawdowns.

  • 📉
    Respect a Broken Thesis

    When growth structurally slows, the original reason to own it is gone — act on that.
