IEX US Equity☆

Held by — the largest Section 13(f) filers reporting a long position in IEX for 2026-Q1. A LAGGED quarterly snapshot filed up to 45 days after quarter-end; it excludes shorts, options, cash and non-US-listed lines. “% of shares out” uses the reported cover-page share count and is omitted when that denominator is unusable. Institutional 13F holdings sum to 101.5% of shares outstanding. Readings above 100% reflect securities-lending double counting: shares on loan to short sellers are reported long by both the lending institution and the one that bought them. FINRA short interest of 1,961,102 shares (settlement 2026-04-30) accounts for the excess.
In these books — membership is looked up in a small NAMED set of constituent books (listed in that column); a miss means “not in those books”, never “not in any index”. Each book carries the issuer's own as-of, and cadences differ (daily to quarterly).
Congress — members with a disclosed STOCK Act transaction in IEX, most recent first, from the API's returned window (so the per-member trade counts in the tooltip are counts within that window, not lifetime). Amounts are disclosed RANGES, not exact values, and reports arrive up to 30–45 days late. As disclosed — no causal claim, not investment advice.
