Michael Burry
アメリカ合衆国 1971-06-19
21st-century American contrarian investor and former physician
Anticipated the subprime crisis with CDS and executed 'the big short'
The habit of reading primary sources yourself is the first step to closing the information gap
Born in 1971 in California, Michael Burry is a former physician turned hedge-fund manager who foresaw the subprime mortgage crisis as early as 2005 and reaped enormous profits through credit-default swaps. His story was chronicled in Michael Lewis's The Big Short and the 2015 film in which Christian Bale portrayed him. A solitary contrarian, he closed Scion Asset Management in 2025.
What You Can Learn
The lessons investors should draw from Burry's career are 'the value of independent analysis' and 'the cost of being right too early.' His practice of going directly to primary sources — scrutinizing individual loan contracts — contains a powerful message for individual investors. No one needs to comb through loan documentation, but the habit of reading a company's annual filings before accepting an analyst's conclusion is a first step toward closing the information gap. At the same time, the risk that 'being right too early still costs money' is equally important. The psychological toll of enduring mounting unrealized CDS losses while investors demanded redemptions was enormous. When taking a contrarian position, setting a maximum-loss threshold in advance and never committing living expenses is indispensable money management. Burry's story is both a contrarian hero's tale and an honest lesson in the loneliness and cost of conviction.
Words That Resonate
I wasn't wrong, I was just early.
I am a value investor. The foundation of my investment style is Benjamin Graham's approach to security analysis.
People want an authority to tell them how to value things, but they choose this authority not based on facts or results.
The late 90s almost forced me to identify myself as a value investor, because I thought what everybody else was doing was insane.
Life & Legacy
Michael Burry is the contrarian investor who saw the collapse of the U.S. housing market coming while the mainstream financial industry was still awash in optimism, and acted on that conviction. His unusual background as a physician and his diagnosis of Asperger's syndrome gave him a cognitive profile that enabled him to analyze markets from a vantage point fundamentally different from the crowd's.
Born in June 1971 in San Jose, California, Burry wore a glass eye from early childhood. He completed pre-medical and economics studies at UCLA, then entered Vanderbilt University School of Medicine and obtained his medical license. During his residency at Stanford University Hospital, Burry began posting his own investment analyses on stock-discussion forums. The sharpness of his work attracted attention from the online investing community and eventually drew the notice of professional investors and fund managers.
In 2000 Burry left medicine and founded Scion Capital. Starting with a modest pool from his father's estate and a handful of outside investors, he initially practiced Benjamin Graham-style value investing. His method of unearthing undervalued small-cap stocks through rigorous fundamental analysis generated returns well above market averages from the outset. In 2001, while the S&P 500 fell roughly 12%, Scion reportedly returned approximately 55%.
What immortalized Burry's name was his short bet against the subprime mortgage market between 2005 and 2007. As the U.S. housing market overheated, Burry individually scrutinized the lending terms and delinquency data of the subprime loans underlying mortgage-backed securities (MBS) and concluded that a surge in default rates was inevitable. On this conviction he built large positions in credit-default swaps (CDS), effectively betting on MBS declines. At the time, voices predicting a housing collapse were vanishingly few; even some of Burry's own investors doubted his judgment.
When the subprime crisis materialized in 2007-2008, Burry's CDS positions generated enormous profits. Scion ultimately delivered roughly $750 million in gains to its investors, with Burry's personal share reportedly approaching $100 million. The saga was detailed in Michael Lewis's The Big Short and dramatized in the 2015 film of the same name, with Christian Bale playing Burry.
After the crisis Burry closed Scion Capital and later resumed managing his personal assets through Scion Asset Management. His distinctive perspective remained undiminished, extending to investments in water resources and Japanese small-cap value stocks. In the social-media era, his terse market commentaries on X (formerly Twitter) commanded outsized attention in the investing community, though his habit of frequently deleting posts only reinforced his solitary stance. In November 2025 he announced the closure of Scion Asset Management and the same month launched a Substack newsletter titled 'Cassandra Unchained.' Named after the Greek mythological seer whose true prophecies were never believed, the title reflects Burry's experience of being dismissed during the subprime crisis and symbolizes a career spent defying market consensus.
Expert Perspective
In the investor landscape, Burry is a unique figure who applied value-investing principles to a macro event-driven strategy. Starting from Graham-style individual-stock analysis, he brought a value investor's eye to a structural macro risk — the subprime mortgage market. Unlike macro investors such as Soros or Dalio, he comes from a medical background, and his meticulous data-analysis skills are grounded in clinical training. His willingness to endure isolation and his distinctive cognitive profile are widely credited as the pillars of a judgment immune to herd mentality.
