IAS — INTEGRAL AD SCIENCE HLDNG CO
IAS (INTEGRAL AD SCIENCE HLDNG CO) is tracked on HoldingsHub across five years of quarterly 13F filings. 42 funds have reported positions historically, with the sum of their latest reported stakes valued at $323.12M. No fund in our coverage reported a position in the latest filing period, which typically means the stock has fallen out of the tracked funds' portfolios rather than that it cannot be bought.
All figures on this page are computed from SEC Form 13F quarterly filings. 13F filers disclose long positions of $100,000 or more within 45 days of quarter end; short positions, options overlays and intra-quarter trades are not included, so treat the numbers as a quarterly snapshot of institutional ownership rather than real-time positioning.
