KTOS institutional ownership: holders, changes, and four-quarter trend
This reverse-ownership view starts with KTOS 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
The latest institutional read on KTOS
KTOS's reported ownership picture is concentrated in a finite manager sample. 2 active managers reported $246.5M in aggregate value. ARK Invest is the largest tracked holder. The sample is too small for a broad concentration reading.
Position changes show where the quarter differed from the prior filing. ARK Invest made the largest measured share-count move at +1.1%. 1 manager initiated positions, led by Soros Fund Management. These filings describe quarter-end positions and do not confirm what managers held after the reporting date.
KTOS's ownership trend is more informative than one filing alone. Holder count is above the trailing average of 1.0. Aggregate value also moves with quarter-end share prices, so dollar changes do not measure active buying by themselves.
Comparable ownership pages show whether KTOS's pattern is unusual. Related ownership pages include AAPL, AXP, KO. Return to KTOS stock research for financial statements, earnings, and company risks.
