Layer 2 · Looking at a Stock¶
Stage Mission
After learning the industry, now we land on a single stock. From "I know where NVDA sits in the AI supply chain" → "I have 1 yaml to discuss with others why I buy / don't buy now."
Stage Invariant — The Backbone of This Layer
Thesis 4 Dimensions = WHAT / WHY / SO WHAT / RISKS Each of the 5 chapters returns to these 4 dimensions, changing only 1 detail. The backbone stays fixed; the content grows.
5 Chapter Map (Learn in Order)¶
| # | Title | 核心一句话 | What You Can Do After | Estimated Time |
|---|---|---|---|---|
| C1 | What Problem Does Your Stock Solve | First WHAT, then WHY | Explain in 30 words why you're looking at a stock | 30 minutes |
| C2 | 4-Dimensional Thesis Framework | Don't miss a single dimension | Expand 1 sentence into yaml, discuss with friends | 1 hour |
| C3 | Valuation/Financial Glossary | Translate terms first | Map each term to the 4 dimensions, fill yaml with real numbers | 1 hour |
| C4 | Real Walkthrough (NVDA) | First time running a real case | Go from transcript to yaml to KPI in 1 loop | 2 hours |
| C5 | Write Your Own Thesis | You only learn by writing | Ship 1 personal thesis within 24 hours | 1 hour + ongoing |
Total Time: ~6 hours of focused reading (1-2 weekends) + C5 continuous review.

C5 --> L3[Layer 3<br/>Multiple Perspectives]
- Day 1 (1.5 hr): C1 + C2 in one go — both are frameworks
- Day 2 (1 hr): C3 with your own ticker's financials to look up terms
- Day 3-4 (2 hr): C4 Follow along with NVDA + wait for next NVDA earnings to truly verify (this step of waiting for a real catalyst is critical, don't skip)
- Day 5-7 (1 hr + ongoing): C5 Ship your first personal thesis, add it to a weekly review rhythm
What You Can Do After This Layer¶
- Use the yaml template (view / supports / red_flags / catalysts / price_outlook) to break down any stock
- Understand financial terms (revenue / EPS / gross margin / segment / RPO / FCF / Rule of 40)
- Turn vague predictions into verifiable KPI predictions (with numbers + verify date)
- Know what to look for before a catalyst (earnings / product launch)
- Have 1 personal thesis + a weekly review rhythm

This is the core layer — spend most of your time here
Layer 1 (Industry) is the introduction; Layer 2 is the main battlefield. Most of your time will be spent cycling between C2-C5 — writing thesis / waiting for catalyst / verifying / rewriting. A year from now, your thesis library will be your most valuable asset.
