📉 Predicted exits, conviction fading

Of Light Street’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 2026-03-31.

⚠️ This predicts the ACTION (whether Light Street 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.

💲 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.

Dip target = the recent high discounted by this investor’s historical tendency to add on weakness. Behavioral, not a guarantee.

🎯 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.

🧬 Factor fingerprint, the style behind the book

81% of Light Street’s day-to-day swings are explained by public, buyable factors (Fama-French 5 + momentum), regressed on their current disclosed book (12 of 13 names, ~451 trading days). Market beta 1.46.

⚠️ 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.
