NATERA INC
826 institutions still hold NATERA INC as of Q1 2026. Tracked across SEC 13F-HR filings, with insider and 13D/G activity surfaced alongside.
Zevenbergen Capital Investments, Natera's largest tracked holder, cut its share count by 2.65% this quarter — a genuine $1.9 million outflow. Its position's reported value climbed $16.8 million anyway, entirely on the stock's price rise. That contradiction sits beside a far larger real move: Assenagon Asset Management, flagged quasi-passive, more than quadrupled its stake, from 60,535 to 250,869 shares, a genuine $51.7 million purchase that now makes it nearly Natera's largest holder. E. Ohman J:or Asset Management made the largest real sale, cutting 88.2% ($6.6 million outflow), while Cary Street Partners Financial grew its small stake more than sevenfold (+655.5%, a real $1.3 million buy).
