🪞 Michael Burry · Scion

Dormant. This investor last filed a 13F for Sep 2025 and has not filed under this CIK since. The holdings below are that final disclosed book, kept as a historical record; no new predictions are produced for a book that has stopped reporting.

Contrarian, special situations + short bias.

Hit rate is measured, not predicted: across 2,030 investor-quarters of walk-forward holdout, the name this model ranked first was the investor’s actual next new buy 1.7% of the time, against 0.62% for a name drawn at random from the same board. That is 2.77x chance. The model ranks the whole board; AUC and the rest of the scoring detail are on the how it works page.

Not separated from chance. Across 20 quarters this ranking scored 0.462 against 0.500, two-sided p = 0.1819. An edge above 0.556 would have registered on this board, so the test could have resolved it and did not. A figure under 0.500 here is the sampling noise around a coin flip, not a signal pointing the wrong way. Pooling every scored row instead of averaging the quarters, which uses the big quarters and the thin ones at their real weight, the same board reads 0.476 over 13,873 rows (two-sided p = 0.360).

💲 Where they bought: accumulation cost

13F shows holdings, not trade prices. Implied average cost is total value ÷ shares; the zone is the price range that quarter, where they accumulated. “vs cost” is today versus that average. This is where they bought, not a future price.

TickerAvg costAccumulation zoneTodayvs cost
PLTR$182.42$131 to $187$177.64-2.6%
NVDA$186.58$153 to $186$227.38+21.9%
PFE$25.48$22 to $24$27.66+8.6%

🎯 Disclosed options: calls vs puts

13F discloses option positions too. Calls lean bullish or levered; puts lean bearish or hedging. This is the not-just-buying side of what they disclose.

⚠️ This is the part the great investors can’t hide: their style is a tilt toward known factors, and every one of these is sold as a cheap index ETF. Buying the factors gets you most of the book for a few basis points. What’s left after the factors (the residual) is noisy on a single concentrated book and is not a reliable edge, read this as transparency about the style you’re copying, not a secret signal. Loadings are in-sample on current static weights, U.S. long positions only. Research, not advice.
