The capstone requires you to write one, share it, and defend it against questions. # Stock Investing Capstone: Write and Defend an Investment Memo The capstone of the stock investing learning path is a written investment memo that integrates all prior skills into one defensible document. This page defines the required sections, a grading rubric, and the oral defense process. ## Key Takeaways - The capstone is a research defense, not a performance review; the goal is process quality, not return prediction. - A complete investment memo has seven required sections, from the business description through position sizing. - The rubric grades documentation quality, not whether the stock performs well afterward. - An oral defense requires you to answer challenges without referring back to the memo. - A memo that identifies what is unknown is better than one that projects false precision. ## The capstone is a research defense The capstone is not a prediction exercise. It is a defense of a process. The evaluator asks: is the business quality assessment supported by primary-source evidence? Are the scenarios built from plausible assumptions? Are the break conditions specific enough to trigger a review? Does the position size reflect the uncertainty in the analysis? A memo that answers these questions with documentation is passing; one that substitutes confidence for evidence is not. ## Required sections The required sections are: (1) Business description in plain language, (2) Business quality scorecard with sourced evidence, (3) Earnings quality scorecard from at least three annual periods, (4) Management and capital allocation review from the proxy statement and cash flow statement, (5) Bull, base, and bear scenarios with the key variable identified, (6) Thesis falsification with at least two break conditions, (7) Position size with stated rationale and portfolio context. ## Rubric Excellent: every factual claim has a source, every assumption is stated, every break condition is specific and measurable, and the position size is tied to the scenario gap. Satisfactory: most claims are sourced, scenarios are plausible if not fully specified. Needs work: assumptions are implicit, break conditions are vague (the stock goes down a lot), or position size is not tied to any documented analysis. ## Oral defense The oral defense is a 15-minute structured review with one or two challenge questions per section. Typical challenges: what would change your bear scenario into a catastrophe case? How did you verify the moat mechanism? Why is the position size appropriate given the bear scenario outcome? Prepare by attempting to break your own thesis before the review begins. ## Applied Exercise: Evidence and Interpretation Use a company you already follow or a fictional company. Begin by writing the decision question. Then create this two-column note: | Evidence | Interpretation | | --- | --- | | What the primary source reports | What you think it means | | What changed from the previous period | Why the change may matter | | What is still unknown | What would resolve the uncertainty | Add a third column only after the first two are complete: **Decision impact**. Mark each item as *supports*, *weakens*, *neutral*, or *unresolved*. This keeps evidence collection separate from persuasion. ## Frequently Asked Questions ### Is this page investment advice? No. It teaches a research and decision process. The examples are educational and do not recommend any security or allocation. ### Do I need to finish every Swoopr stock page before using this? No. The learning path intentionally points to deeper reference material only when it becomes relevant to the skill being practiced. ### How do I know when I am ready for the next stage? Use the stage gate. Progress when you can produce the required artifact without relying on the lesson as a script and can explain both the conclusion and its limitations. ### Should I use a stock screener or AI summary instead of filings? Those tools can help with discovery and organization, but material facts should be checked against the closest available primary source when practical. A summary is not a substitute for the evidence it summarizes. ### What if the evidence conflicts? Preserve the disagreement. Do not average conflicting signals into a false sense of certainty. Identify which evidence is more direct, more relevant, and more current, then record what would resolve the conflict. ## References - [Swoopr Stock Research Workbench](https://www.getswoopr.com/research/) - [Swoopr Research Methodology and Formulas](https://www.getswoopr.com/research/methodology/) - [Investor.gov: Researching Investments](https://www.investor.gov/introduction-investing/getting-started/researching-investments) - [FINRA: Evaluating Stocks](https://www.finra.org/investors/investing/investment-products/stocks/evaluating-stocks) ## Disclaimer This page is for educational purposes only and does not constitute investment, financial, or trading advice.
