The whale race?Each line is $1 copying that whale's filings at every quarterly deadline, rebalanced each quarter, rebased to your chosen start date. Add or remove whales with the tags; press Replay to sweep quarter by quarter. Dividends excluded.

what copying each whale's filings returned, $1 at your chosen start
What a copycat would have made: buying each filed book, bought at every filing deadline, rebalanced quarterly. Price returns, dividends excluded on all lines. Copycat of public filings, not the fund's actual performance. * = under 80% of the book priceable, read loosely.

The Crowd Meter: quiet ownership crowd arriving crowded, late-money risk

Crowd arriving fastest?Names whose active institutional holder count grew fastest in the latest filings. Our ten-year backtest says fast pile-ins mark late money, so read this as a caution list, never as picks.

Fast pile-ins mark late money, not early money. These are caution flags, not picks.

Fire exits?Names where a big share of the active holders closed out entirely last quarter, right after the name was crowded. The unwind phase of the crowding cycle.
