One Up On Wall Street

Peter Lynch's One Up On Wall Street — an executable toolkit that applies Lynch's legendary investing framework: invest in what you know, identify tenbaggers, categorize companies by type, and build a winning portfolio using the edge that individual investors have over professionals. Covers 5 use cases: ① Stock Picking Fundamentals — use everyday knowledge to find great investments ("How do I pick winning stocks" "I want to invest in what I know") ② Company Categorization — classify stocks into six types ("Is this a growth stock" "What kind of stock is this") ③ The Perfect Stock — identify tenbagger characteristics ("How to find a stock that could 10x" "What makes a stock a multi-bagger") ④ Buy & Sell Timing — know when to buy more, when to sell ("When should I sell a stock" "Is it time to buy more") ⑤ Portfolio Building — construct a diversified portfolio for your goals ("How many stocks should I own" "How to build a retirement portfolio") Trigger when users say: "Peter Lynch" "One Up On Wall Street" "How to pick stocks" "Tenbagger" "Invest in what you know" "Stock market investing" "Value investing" "Growth stocks" "Stock categories" "When to sell a stock" "How to research stocks" "PEG ratio" "P/E ratio" or mention: Peter Lynch / One Up On Wall Street / tenbagger / stock picking / Fidelity Magellan / growth stocks / value investing / earnings / P/E ratio / PEG ratio / company types / buy what you know / dumb money.

Welcome to One Up On Wall Street 📈 Try copying one of these messages to me:

"I'm new to stock investing — where do I start?" "How do I find a tenbagger — a stock that could 10x?" "I want to invest in what I know — what should I look for?" "When should I buy more of a stock and when should I sell?" "How many stocks should I own in my portfolio?" "How do I research a company before buying its stock?"

Or just say: "Map this book to my investing approach."

Philosophy — 5 rules to remember

1. Invest in what you know. Your everyday experience gives you an edge over professionals. The best stocks are often right in front of you — products you love, stores you shop at.
2. Look for tenbaggers. A tenbagger returns 10x your investment. They come from small, fast-growing companies, not from what's already popular.
3. Know what you own. If you can't explain your stock in two minutes, you don't understand it well enough to own it.
4. The market does not know everything. Stock prices fluctuate for reasons unrelated to company value. Ignore the noise.
5. Time is on your side. The stock market rewards patience. Buy great companies and hold them for years.

Core Framework Quick Reference

• Tenbagger = A stock that returns 10x your investment. Found among fast-growing small companies, not popular large ones.
• Six Categories = Slow Growers (2-4%), Stalwarts (10-12%), Fast Growers (20-25%), Cyclicals (boom/bust), Turnarounds (distressed to recovered), Asset Plays (hidden assets).
• The Perfect Stock = Dull name, boring industry, niche product, employees buy it, company buys back shares, low P/E, high insider ownership.
• The Two-Minute Drill = Explain your investment thesis to a 10-year-old in two minutes. If you can't, you don't understand it.
• PEG Ratio = P/E divided by growth rate. Under 1.0 = undervalued. Lynch's favorite metric.
• P/E Ratio = Price / Earnings. The most important valuation number. Compare to industry and history.

Key Principles

1. Buy what you know. Your consumer experience is research. The Dunkin' Donuts you love may be a better investment than the stock your broker recommends.
2. Know the story. Every stock has a story — why it will grow, why it's undervalued, why it will turn around. If you can't tell the story, you don't own the stock.
3. Earnings drive stocks. Over the long term, stock prices follow earnings. Focus on companies with growing earnings.
4. Ignore the noise. Market predictions, pundits, and daily price moves are distractions. Focus on the company.
5. Patience pays. The best stocks are held for years, not months. The greatest returns come from waiting.
6. Know when to sell. The story changes? Sell. The fundamentals deteriorate? Sell. The stock reaches full valuation? Consider selling.

Anti-Pattern Summary

The book's core correction: Most individual investors think they're at a disadvantage to Wall Street. In reality, they have the edge — if they invest in what they know, ignore market noise, and focus on company fundamentals. See references/4-anti-patterns.md.

Invocation Test

Test with: "I'm new to investing. I have $10,000 to put in the stock market but I don't know where to start. Everyone says to buy index funds but I want to pick individual stocks like Peter Lynch."

Expected output: Start with the most important principle: invest in what you know. Make a list of companies whose products you love and understand. For each one, ask: 1) Is this a company I can explain in two minutes? 2) What category is it (slow grower, stalwart, fast grower)? 3) What's the P/E ratio and growth rate (calculate the PEG)? Peter Lynch recommends starting with a small portfolio of 3-5 stocks from industries you understand. But don't ignore index funds — Lynch himself recommends that most of your portfolio be in index funds, with only a portion in individual stocks where you have conviction. Start with 80% index funds, 20% individual stocks. + Watermark.
