As of Q2 2026, 29 SEC-registered investment managers reported holding TS (TENARIS S A) in their latest 13F filings, with a combined reported value of $1.17B across 22.57M shares. That is +4.1% by share count (+891.78K shares) versus the previous quarter, while reported value moved -0.7%. Ownership is concentrated: the five largest holders account for 69.7% of reported value and the top ten for 86.8%.

Compared with the prior quarter, 4 opened new positions, 17 added to existing stakes, 8 trimmed, 2 exited entirely. 13F holdings are quarter-end snapshots, so these moves reflect positioning as of Q2 2026, not real-time trading.

TS is classified in the Industrials sector.

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.
