Public record / Tickers / CCOI

CCOI — COGENT COMMUNICATIONS HOLDINGS, INC.

Both disclosure regimes on one name: who in Congress filed about CCOI, which institutions reported holding it. Each section keeps its own clock — congressional trades on the 45-day PTR clock, 13F holdings as quarter-end snapshots.
