13F stock ownership research
Natera Inc (NTRA) institutional holdings and quarterly fund activity
This reverse-ownership view starts with NTRA and shows every matching position in SnowballHare's tracked 13F manager universe. It connects holder-level changes with four-quarter history and company research without presenting delayed filings as live ownership.
Deterministic analysis from filing data
How institutions moved in NTRA this quarter
NTRA's reported ownership picture is concentrated in a finite manager sample. 3 active managers reported $645.8M in aggregate value. Coatue Management is the largest tracked holder. The sample is too small for a broad concentration reading.
New, increased, reduced, and exited positions separate the moving pieces. Duquesne Family Office made the largest measured share-count move at +22.0%. These filings describe quarter-end positions and do not confirm what managers held after the reporting date.
Looking back across quarters separates persistence from a single-period move. Holder count is above the trailing average of 2.5. Aggregate value also moves with quarter-end share prices, so dollar changes do not measure active buying by themselves.
Comparable ownership pages show whether NTRA's pattern is unusual. Related ownership pages include AAPL, AXP, KO. Return to NTRA stock research for financial statements, earnings, and company risks.
