Filing facts / Q1 2025

The record behind the replay.

The replay is anchored to the May 15 SEC filing, not the February announcement. It cannot measure the announcement reaction, and the earlier disclosure makes it unsuitable as a clean test of a new-information effect at the 13F timestamp.

Combined from 1 non-option row for this security in this single filing. The original table reports values in USD. Value is a quarter-end mark, not purchase cost. Source rows retain their manager designations in the linked table.

No UBER CUSIP appears in the reviewed December 2024 original table or April 2025 additional-holdings amendment. The amendment supplements the original. The separate February public announcement is retained above.

How to read the numbers

A replay you can check.

01 / Start after the filing

The base entry is the next trading session’s close after the filing date, whether the filing arrived during trading or after the close. Scion’s Alibaba filing arrived during market hours; the other selected filings arrived after the close. It is a reproducible daily-price convention, not the earliest executable trade. Overnight and first-session moves are already in that entry price.

02 / Keep the exit fixed

Choose an exit 20 or 60 trading sessions after the base entry. Waiting one or five sessions moves the entry only. All scenarios exit on the same date; delayed entries therefore have shorter holding periods. Sessions follow the observed SPY trading dates, including holiday gaps.

03 / Compare like with like

Price change = (exit close ÷ entry close − 1) × 100. SPY uses the same dates. The difference is measured in percentage points, not risk-adjusted alpha. The chart rebases both series to 100 at the selected entry. Prices are USD closes from Yahoo Finance; the reviewed windows contain no recorded stock splits.

04 / Keep the limits visible

Dividends, trading costs, taxes and slippage are excluded. The snapshot-to-filing comparison is not the manager’s return. A weekend quarter-end uses the last trading close on or before that date. For an intraday filing, the filing-day close includes post-disclosure trading. Options, short positions and a manager’s actual trade dates are not reconstructed. These six selected cases cannot establish causation, predictive power or a profitable strategy.
