Practice Drills: Applying Munger's Mental Models to a Live Stock Pick
A hands-on drill course for serious investors who know Munger's mental models and now need to use them on a real decision. You pick one live NSE stock and run it through the latticework, drill by drill: test whether it sits inside your circle of competence, filter a screener.in shortlist through the too-hard pile, and map which models actually apply. Then invert the thesis, measure the stock against your opportunity cost, quantify the compounding machine through ROCE and reinvestment runway, and score the moat on evidence. Read promoter and management incentives straight from the annual report, audit related-party deals and pledges, and run Munger's psychological tendencies against your own thesis. Finish by setting a buy price with a margin of safety, sizing the bet with Kelly-style limits, and writing a complete checklist and decision journal entry you can act on. Every drill uses Indian companies, NSE and BSE filings, and INR figures.
