Reported totals, quarter ended 2026-06-30
166 reporting managers held 59,534,718 shares, reported value $2,533,294,605 exactly as filed. Values are position values transcribed from the filings, not current market prices.

Shares outstanding check: 393,312,793 shares reported by the issuer (SEC XBRL, period ended 2025-12-31). Reported 13F shares equal 15.1% of that figure. This page passed the publication sanity gate before listing.
YPF in this quarter's filings
Concentration check: the largest reported position, Aquamarine Financial (Cayman) Ltd with 12,444,948 shares, is 20.9% of all shares reported for YPF this quarter. The five largest reporting managers together account for 58.9% of the reported total, so the headline total is dominated by a handful of large managers.
Reported quarter-over-quarter change: the reporting-manager count rose by 16 versus the quarter ended 2026-03-31, and reported shares moved +29.45% (+13,545,613 shares). That is a comparison of two filing snapshots, not a record of trades on any single day.
Shares-outstanding cross-check: reported 13F shares equal 15.1% of the issuer share count used at the publication gate (393,312,793 shares, issuer period ended 2025-12-31). The gate publishes a ticker only when that relationship is plausible; lending chains can push reported totals above a simple ownership share, which is why the figure is a sanity check and not an ownership percentage.

What this page is and is not
Form 13F reports are quarterly holdings snapshots. Managers file up to about 45 days after quarter-end, so these figures describe reported positions as of the quarter-end date, not holdings today. 13F lists reportable long positions from managers above the SEC reporting threshold and omits short positions entirely.
