Growth & Quality Investing

Growth investing is the discipline of paying for tomorrow's earnings — not yesterday's book value. Done well, it produces tenbaggers, multi-baggers, and the rare hundred-bagger. Done poorly, it produces the worst drawdowns in markets. This book is the toolkit for telling the difference: what makes a real compounder, what makes a glamorous story stock, and how to value the gap.

Who this book is for

You can read a 10-K. You understand revenue, margins, and free cash flow. You've watched a "growth" stock you owned drop 70% in 2022 and want to know what you missed. You've heard the words moat, TAM, network effect, founder-led, Rule of 40 — and you want a unified framework that pulls them together. This book is for the investor moving from intuition to discipline.

What you walk away with

• A clear understanding of why growth and value are not opposites — and why the best long-term records belong to investors who refuse to choose.
• Philip Fisher's original framework: the 15 points, the scuttlebutt method, management integrity, and why he was the bridge between Graham and Buffett.
• Peter Lynch's practical playbook: six categories of stocks, the PEG ratio, the two-minute drill, and the discipline behind the Magellan record.
• Modern growth investing: software economics, subscription models, SaaS unit economics, platform businesses, the role of founder-CEOs, and what the 2022 crash taught us.
• A complete tour of the SaaS dashboard: the Rule of 40, ARR, NRR, magic number, LTV/CAC, CAC payback, gross margin trends, and free cash flow margin.
• Network effects in depth — direct, two-sided, data, local-vs-global — plus the cold-start problem, network decay, and how to quantify network value.
• Economic moats for the modern era: switching costs, brand, distribution, regulatory, IP, and ecosystem moats — and how to measure their depth via ROIC.
• Reinvestment and compounding: ROIC versus cost of capital, capital allocation, and worked compounder case studies (Costco, Visa, Microsoft).
• Founder-led companies: why founders outperform on long horizons, the data behind the premium, and case studies of Bezos, Musk, Zuckerberg, Hastings, and Ellison.
• Total addressable market done seriously: top-down vs bottom-up estimation, the TAM trap, whitespace mapping, and how disclosure tactics can mislead.
• Profitability runways: operating leverage, gross margin scaling, SBC drag, the dilution math, and the inflection from burn to free cash flow.
• Valuing high-growth stocks when traditional methods break: EV/Sales, reverse DCF, cohort-based models, real options, and disciplined growth multiples.
• Growth at a Reasonable Price (GARP): the Lynch heritage, PEG mechanics, and how the 2022 re-rating brought GARP back into focus.
• Sixteen worked case studies of real growth winners and losers: Amazon, Apple, Google, Microsoft, Netflix, Tesla, Nvidia, Shopify, Salesforce, Adobe, Block, Snowflake, ASML, LVMH, Costco, and Hermès.

How to read this book

Chapters 1–3 cover the philosophical foundations: what growth investing is, and the two intellectual lineages (Fisher and Lynch) that built the modern playbook. Chapters 4–6 introduce the modern toolkit: SaaS metrics, network effects, and the post-2010 growth era. Chapters 7–11 cover the analytical frameworks — moats, compounders, founders, TAM, and profitability runways. Chapter 12 handles valuation; Chapter 13 covers GARP; Chapter 14 walks through real case studies. Read the foundations in order; treat the rest as reference once you have the vocabulary.
