Everything below comes from forms this entity filed with the US Securities and Exchange Commission — not an estimate, not a survey, and not a valuation.
Computed from SEC EDGAR filings and closing prices — not copied from any wealth ranking. Dataset . How we calculate this.
Read the share counts carefully. 9 of these 10 stakes were reported on filings shared with other entities.
On a joint filing every named filer is listed against the whole position, so the same block of stock also appears under the other names. Adding those figures together would invent stock that does not exist. Joint positions are marked joint wherever they appear, and nothing on this site sums a position across owners.
What PERCEPTIVE LIFE SCIENCES MASTER FUND LTD holds, and what those companies hold in turn. A name in plain text is the end of the trail: we hold the filing that names it, but no separate record to open.
It draws at most eight holdings per level and stops after two levels, showing the holdings we can follow further first, not the largest ones — for every position in order of size, read the table below. Entities that own each other are drawn once: a chain never doubles back on a name it has already passed through.
Every company this entity has filed on, largest reported position first. Each row links to the filing it came from.
