Event-driven investing
From catalyst to thesis, valuation change, and portfolio exposure
Merger arbitrage, restructurings, spinoffs and tender offers are the classical event-driven universe. The same discipline applies to policy decisions, macro releases, geopolitical shocks and operational disruptions once you can name the mechanism, the line items it moves, and the assumptions it revises. Each record below does exactly that, on a longer horizon than the trading scanner.

Add this thesis to my researchTheses carry into your own valuation model with the assumptions already flagged.
Methodology
What qualifies as an event. A discrete, dated or near-dated occurrence that changes a future cash-flow distribution. Corporate actions qualify by construction. Policy, macro, geopolitical and operational events qualify only when a specific line item can be named.
Line items before narrative. A thesis must state which financial line items move — revenue, gross margin, capital intensity, cost of debt — before it states a direction. A direction without a line item is a sentiment claim and is rejected.
Assumption tracking. Revised valuation assumptions are recorded against the model, so when a later event contradicts one, the affected theses are identifiable rather than forgotten.
Limits. Impact and confidence scores are ordinal model outputs, not probabilities, and are not comparable across asset classes. Nothing here is investment advice.
