Direct Answer
The 100-Day Stock Investor Practice Plan structures practice into five phases: mechanics and risk (Days 1 to 20), reading businesses (Days 21 to 45), comparing and valuing (Days 46 to 70), stress testing the thesis (Days 71 to 90), and capstone (Days 91 to 100).
Key Takeaways
- The first 20 days focus on mechanics and risk before any stock analysis begins.
- Days 21 to 45 require reading at least two real 10-K filings using primary SEC sources.
- Days 46 to 70 introduce valuation and peer comparison using documented frameworks.
- Days 71 to 90 apply scenario analysis and thesis falsification to a position already analyzed.
- The capstone produces a complete investment memo that integrates all prior skills.
Days 1 to 20: mechanics and risk
Open a practice brokerage account. Learn the order types available and place five practice orders with written rationales. Read FINRA's margin guidance and Investor.gov's asset allocation overview. Write a one-page investment policy: your position size limits, your concentration limits, and the conditions under which you would consider using a margin account. Deliver a written investment policy by day 20.
Days 21 to 45: read businesses
Select two companies in different industries. Read the 10-K for each. Complete the business quality scorecard and earnings quality scorecard for both. Write a one-paragraph business description for each that you could explain to someone with no financial background. By day 45, you should have two completed scorecards and two business descriptions sourced to primary filings.
Days 46 to 70: compare and value
For one of the two companies analyzed, find two peers in the same industry. Compare the three companies on revenue growth, margins, return on equity, and free cash flow yield. Identify which company the market appears to value most highly and research why. Build a simplified bull, base, and bear scenario for the company you find most interesting. Deliver the scenario analysis by day 70.
Days 71 to 90: stress the thesis
Apply thesis falsification to the company you chose in phase 3. Write two break conditions. Follow one earnings release using the three-phase checklist. After the release, update your scenario analysis based on new data. By day 90, you should have an updated thesis, a documented post-earnings review, and a position-sizing decision with written rationale.
Days 91 to 100: capstone
Combine all prior work into a complete investment memo following the required sections from the capstone lesson. Share the memo with someone who can challenge it, or review it yourself against the rubric. Record the oral defense questions you received and your answers. The capstone deliverable is the complete memo plus a written reflection on what you would research differently if you started over.
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.
