Case studies built from real positions and the research memos that judged them — including the ones we got wrong. Every claim traces to a cited memo; every quiz answer is derivable from it.
The method, ticker-free — glossary terms linked inline.
One definition per term, used everywhere it appears.
Every quiz across courses and cases, in one place.
A trader down $25,000 asks the internet how to trade SPY 0DTE options. The most-upvoted answers — EMA crosses, credit spreads, afternoon bounces, OPEX avoidance — get graded here against 890 measured sessions of our own tape. Most of them fail. What survives is a clock, not a chart pattern.
The same morning Hertz was fading, a healthcare-software company nearly doubled before the open on an earnings report whose headline numbers barely moved. This case teaches the discrimination that matters most in big-move analysis: a SQUEEZE mean-reverts when the forced buying exhausts; a RE-RATING holds or fails on whether the next quarter delivers. They demand opposite trades, opposite risks, and opposite falsifiers.
A $2 rental-car stock jumps ~30% in a day on huge volume, doubles its Reddit mentions every few hours, and the internet calls it a short squeeze. The positioning evidence said otherwise — and the option buyer who chased it anyway lost half the premium in a day. Every claim in this course traces to the cited research memo.
Educational only — not investment advice, and not a recommendation to buy or sell anything. Vendor-licensed number tables stay on the operator research surface; these courses carry public-domain filings and our own derived conclusions.
