Andreas Halvorsen · Viking Global
Long-short fundamental (Tiger cub).
The board ranks candidate holdings for a later filing. The stored hit-rate and lift summaries have not been reconciled to the serving model version, so they are withheld. The ranks are not return forecasts. See the methodology for the separate historical ranking evaluation.
Ranking evidence is model- and population-specific. The current serving board and stored per-investor holdout summaries do not yet have a verified version mapping, so no per-investor hit rate or AUC is shown.

Predicted exits, conviction fading
Of Andreas Halvorsen · Viking Global’s current disclosed holdings, the names a model flags as most likely to be EXITED or TRIMMED next quarter, before the 13F shows it. Model score (not a calibrated probability), ranked. Holdings as of 2026-06-30.
| Ticker | Company | Weight | Last move | Sell likelihood |
|---|---|---|---|---|
| ATI | Ati Inc | 0.65% | trimmed last Q | ▲▲ 70 |
| TSLA | Tesla Inc | 0.66% | trimmed last Q | ▲▲ 69 |
| MDLN | Medline Inc | 0.54% | trimmed last Q | ▲▲ 69 |
⚠️ This predicts the ACTION (whether Andreas Halvorsen · Viking Global reduces the position), not a return and not a short. A 13F shows long positions only, so a “sell” here means exiting or cutting a long, never shorting the stock. Walk-forward validated on the decision (AUC ≈ 0.66), but acting on it is not shown to make money. Research, not advice.

Reported value per share: latest filing
13F shows quarter-end holdings, not trades or trade prices. The “Reported $/sh” column is the filing’s reported value ÷ shares, which is the quarter-end price, not what the fund paid. The range is the price band that quarter. A snapshot shows only the net position at two dates, so the fund may have traded more, or at other prices, in between. “vs reported” is today versus that figure, not a future price.
| Ticker | Reported $/sh | Quarter range | Today | vs reported |
|---|---|---|---|---|
| V | $343.09 | $297 to $342 | $385.45 | +12.3% |
| TSM | $477.57 | $336 to $476 | $453.31 | -5.1% |
| APD | $293.18 | $268 to $302 | $283.87 | -3.2% |
Factor fingerprint, the style behind the book
86% of Andreas Halvorsen · Viking Global’s day-to-day swings are explained by public, buyable factors (Fama-French 5 + momentum), regressed on their current disclosed book (15 of 15 names, ~390 trading days). Market beta 1.02.
⚠️ 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.
This mirror’s track: backtest vs S&P 500
Read this honestly. Leak-free walk-forward backtest: top-10 predicted new buys ranked from a broad ~2,000-name universe known at the rebalance date, equal-weight, 1-quarter holds, complete quarters only, gross (before costs). Small samples, per-investor edges are noisy and not statistically significant. Historical simulation only. Portfolio outcomes do not establish prospective performance, and the average is sensitive to a small number of quarters. Past performance does not predict future results. Not investment advice.
