Scion Capital (Michael Burry)

The California hedge fund founded in November 2000 by Michael Burry — a physician turned value investor who had built a following on internet message boards — which became the first well-known fund to buy credit default swap (CDS) protection on subprime mortgage bonds, starting with $60m from Deutsche Bank on 19 May 2005 (Michael Lewis, as cited by Wikipedia). The trade lost money and provoked an investor revolt for almost two years — a side pocket locked up about half of investors' money (Lewis, secondary) and the fund lost ~18% in 2006 (secondary table) — before paying off in 2007, when Scion reportedly returned ~138% net and made ~$725m for investors and ~$100m for Burry (Lewis, Vanity Fair, Apr 2010, via Wikipedia). The record from 1 Nov 2000 to June 2008 is reported at +489% net of fees against ~2% for the S&P 500 (same source); all of it is unaudited letter-based reporting (rule 4(c)). Burry closed Scion Capital in 2008, reopened as Scion Asset Management (2013), and became better known for his 13F filings — GameStop (2019–20), index puts (2023), Palantir and Nvidia puts (2025) — than for his returns, before Scion's SEC registration was terminated in November 2025. Its story turns on the hardest problem for any convex short: being early is indistinguishable from being wrong — for a while.
