Dollar size maxes out at 35 of 35 on the strength of Gordon's $16,150,000.00. Everything else is thin: conviction adds 1.4 of 20 because both stakes were already large, breadth 15 of 30 for two insiders, and seniority 5 of 15 since both are directors rather than officers.
• Carl L. Gordon's 950,000-share purchase was reported alongside ORBIMED ADVISORS LLC as a co-filer.
• Affiliated filers reporting the same purchase are counted once, so the $16,150,000.00 is not double-counted in the cluster total.
• This is why the cluster shows 2 insiders despite three filing documents.
