Direct answer: A Portfolio Autopsy reconstructs an investment decision using information available at the time. It identifies the original thesis, the assumptions that mattered, the evidence that weakened or broke the thesis, and whether valuation, leverage, fraud, or portfolio construction amplified the loss. The purpose is not to make past failures look obvious. It is to improve future decisions under uncertainty.
Portfolio Autopsies: What Actually Went Wrong?
What is a portfolio autopsy?
A portfolio autopsy reconstructs an investment decision from the perspective of an investor who did not know the outcome. The goal is to separate what was knowable at the time from what became knowable only in hindsight.
Every autopsy attempts to answer the same questions. What security or exposure did investors actually own? What was the bull thesis and what evidence supported it at the time? When did the evidence first begin to contradict the thesis? When did the thesis definitively break? What amplified the loss beyond what the business fundamentals alone would have produced?
The library covers corporate collapses, accounting frauds, financial crisis failures, leveraged buyout failures, disruption failures, crypto collapses, fund failures, and systematic investor mistakes. The organizing principle is mechanism, not outcome: understanding why a failure happened matters more than cataloguing that it happened.

Frequently Asked Questions
What is a portfolio autopsy?
A portfolio autopsy reconstructs an investment decision using information available at the time. It identifies the original bull thesis, the assumptions that mattered, the evidence that weakened or broke the thesis, and whether valuation, leverage, dilution, fraud, cyclicality, or portfolio construction amplified the loss. The goal is not to make past failures look obvious in hindsight. It is to improve future decision-making under uncertainty by understanding what was knowable and when.
What failure mechanisms appear most often in investment collapses?
Across hundreds of investment failures, the most common mechanisms are accounting fraud that conceals real economics, excessive leverage that turns moderate asset declines into solvency events, technological disruption that eliminates the basis of the thesis, demand pull-forward that confuses temporary with structural demand, and management misalignment. Many failures involve multiple mechanisms simultaneously.
How can studying historical failures improve investing?
Historical failure studies build a mental library of failure patterns: the gap between reported earnings and cash flow, leverage ratios that eliminate margin for error, demand pull-forward masquerading as structural growth, and management behavior that historically precedes corporate failure. Recognizing these patterns raises the probability of asking the right questions early.
