Why Growth Matters

A company that grows its earnings will almost certainly see its stock price grow too. Let's understand why growth is so powerful.

The Growth Equation

Stock Price = Earnings × Multiple (P/E)

If earnings grow, stock price tends to follow—even if the multiple stays the same.

Example:

  • Year 1: $5 EPS × 20 P/E = $100 stock price
  • Year 5: $10 EPS × 20 P/E = $200 stock price

Earnings doubled → Stock price doubled. That's the power of growth.

The Rental Property

You buy a rental property for $200,000 generating $15,000/year rent.

Over 10 years, rents increase to $25,000/year. Even at the same valuation multiple, your property is now worth $333,000.

Growth in the underlying cash flows drives value—for real estate and stocks alike.

Types of Growth

Revenue Growth

What it is: Increase in total sales

Why it matters:

  • Shows demand for products/services
  • Indicates market share gains
  • Foundation for earnings growth

Earnings Growth

What it is: Increase in profits

Why it matters:

  • Directly drives stock value
  • Shows operational leverage
  • Funds dividends and buybacks

Dividend Growth

What it is: Increase in cash payments to shareholders

Why it matters:

  • Growing income stream
  • Sign of confidence from management
  • Compounds over time

Key Takeaways

  • Growing earnings typically lead to growing stock prices
  • Revenue growth is the foundation; earnings growth is the goal
  • Consistent growth is more valuable than erratic growth
  • Growth compounds—small differences become huge over time

The Compounding Effect

Small differences in growth rates create massive differences over time:

Initial EPSGrowth RateEPS in 10 YearsEPS in 20 Years
$1.005%$1.63$2.65
$1.0010%$2.59$6.73
$1.0015%$4.05$16.37
$1.0020%$6.19$38.34

A company growing at 15% will have 6x the earnings of one growing at 5% after 20 years!

Growth vs. Value: A False Dichotomy

Some investors think you must choose:

  • Growth investing: Buy fast growers at any price
  • Value investing: Buy cheap stocks regardless of growth

The truth: The best investments combine both—reasonable growth at reasonable prices.

GARP: Growth at a Reasonable Price

GARP investors seek companies with:

  • Above-average growth rates
  • Below-average valuations (relative to growth)

This is essentially what ShareValue.ai helps you find—quality growth at fair prices.

When Growth Matters Most

High Impact:

  • Long time horizons (growth compounds)
  • Reinvesting companies (growth funds more growth)
  • Expanding industries (tailwinds help)

Lower Impact:

  • Short time horizons (valuation matters more)
  • Mature industries (growth is limited)
  • High-dividend payers (income, not growth, is the goal)

Growth Red Flags

🚩 Unsustainable growth — Fueled by one-time factors

🚩 Unprofitable growth — Revenue up, losses up too

🚩 Acquisition-driven growth — Buying growth, not earning it

🚩 Slowing growth — Deceleration often continues

🚩 Growth at any cost — Destroying value to grow

Growth Traps

  • Assuming past growth will continue forever
  • Paying any price for growth
  • Confusing revenue growth with earnings growth
  • Ignoring the quality of growth
