--- title: "Portfolio Autopsies: What Went Wrong?" description: "Investment post-mortems on famous failures: Enron, Lehman Brothers, FTX, Theranos, and more. Reconstruct each thesis, find the warning signals." canonical: https://www.getswoopr.com/investments/portfolio-autopsies/ source: "Swoopr Investment: https://www.getswoopr.com" --- ## 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. ## Autopsy library - [Enron Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/enron/) Corporate Collapse - [WorldCom Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/worldcom/) Accounting Fraud - [Lehman Brothers Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/lehman-brothers/) Financial Crisis Failure - [Bear Stearns Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/bear-stearns/) Financial Crisis Failure - [FTX Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/ftx/) Fraud / Crypto Exchange - [Theranos Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/theranos/) Fraud / Private Company - [Wirecard Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/wirecard/) Accounting Fraud - [Washington Mutual Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/washington-mutual/) Financial Crisis Failure - [Hertz Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/hertz-2020/) Bankruptcy - [JCPenney Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/jcpenney/) Retail Disruption / Execution Failure - [Toys R Us Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/toys-r-us/) LBO Failure / Retail Disruption - [Sears Holdings Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/sears-holdings/) Retail Disruption / Management Failure - [Blockbuster Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/blockbuster/) Disruption Failure - [WeWork Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/wework/) Valuation Collapse / IPO Failure - [Nikola Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/nikola/) SPAC Fraud - [GE Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/general-electric-2000-2018/) Conglomerate Deterioration - [Kodak Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/kodak/) Disruption Failure - [Silicon Valley Bank Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/silicon-valley-bank/) Bank Failure / Duration Risk - [Peloton Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/peloton/) Post-COVID Demand Normalization - [Beyond Meat Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/beyond-meat/) Growth Thesis Failure - [AOL Time Warner Merger Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/aol-time-warner-merger/) M&A Failure ## 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. ## More in This Section - [100% Employer Stock Portfolio Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/100-employer-stock-portfolio/) - [23andMe Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/23andme/) - [AIG 2008 Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/aig-2008/) - [AMC Entertainment Meme Stock Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/amc-entertainment-2021-meme-episode/) - [Archegos Capital Management Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/archegos-capital-management/) - [ARK Innovation ETF Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/ark-innovation-etf-2021-2022/) - [Averaging Down Into a Broken Thesis Autopsy: What Went Wrong?](https://www.getswoopr.com/investments/portfolio-autopsies/averaging-down-into-a-broken-thesis/) - [Bayer-Monsanto Acquisition Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/bayer-monsanto-acquisition/) - [Bed Bath & Beyond Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/bed-bath-and-beyond/) - [BlackBerry Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/blackberry/) - [Borders Group Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/borders-group/) - [Canoo Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/canoo/) - [Carvana Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/carvana-2021-2023/) - [Celsius Network Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/celsius-network/) - [Chasing High Dividend Yields Investment Autopsy: What Went Wrong?](https://www.getswoopr.com/investments/portfolio-autopsies/chasing-high-dividend-yields/) - [Chesapeake Energy Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/chesapeake-energy-2014-2020/) - [Circuit City Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/circuit-city/) - [Country Garden Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/country-garden/) - [Credit Suisse Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/credit-suisse/) - [Crypto ICO Bubble 2017 Investment Autopsy: What Went Wrong?](https://www.getswoopr.com/investments/portfolio-autopsies/crypto-ico-bubble-2017/) - [DiDi Global Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/didi-global/) - [Dot-Com Bubble 2000 Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/dot-com-bubble-2000/) - [Evergrande Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/evergrande/) - [First Republic Bank Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/first-republic-bank/) - [Fisker 2024 Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/fisker-2024/) - [GameStop 2021 Meme Stock Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/gamestop-2021-meme-episode/) - [HP-Autonomy Acquisition Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/hp-autonomy-acquisition/) - [Intel Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/intel-2000-2026/) - [Invitae Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/invitae/) - [Japanese Asset Bubble 1989 Investment Autopsy: What Went Wrong?](https://www.getswoopr.com/investments/portfolio-autopsies/japanese-asset-bubble-1989/) - [Kraft Heinz 2019 Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/kraft-heinz-2019/) - [Leveraged ETF Buy-and-Hold Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/leveraged-etf-buy-and-hold/) - [Long-Term Capital Management Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/long-term-capital-management/) - [Lordstown Motors Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/lordstown-motors/) - [Lucid Motors Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/lucid/) - [Luckin Coffee Investment Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/luckin-coffee-2020/) - [Madoff Investment Securities Autopsy](https://www.getswoopr.com/investments/portfolio-autopsies/bernard-l-madoff-investment-securities/) - [Meme Stock Bubble 2021 Investment Autopsy: What Went Wrong?](https://www.getswoopr.com/investments/portfolio-autopsies/meme-stock-bubble-2021/) - [Mt.
