What this is

This page reverses the usual 13F view: instead of "what does Buffett hold," it answers "who holds NVDA?" Across the dozen tracked filers, all current 13F-disclosed holders of TACT are listed, with the position size and what fraction of each filer's overall portfolio it represents.

Caveats: only the filers tracked here are included (~12 names) — not the whole 13F universe (~6,000 filers). Position values are at the most recent quarter-end, not current market price. Only long positions are visible; shorts and synthetics aren't.
