Kosmos Energy LTD (KOS) SEC 13F Holdings (Q2 2026): Institutional Buyers & Sellers

KOS ranks #2331 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

KOS is a disclosed holding of Two Sigma (Two Sigma Investments), one of the tracked superinvestors on AlphaSMO — it makes up 0.0% of that fund's own 13F portfolio.

KOS is a top-conviction position for Equinox Partners Investment Management LLC — at 20.5% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in KOS belongs to California State Teachers Retirement System, but the position matters far more to Equinox Partners Investment Management LLC, who has 20.5% of their own portfolio riding on it — a reminder that the biggest holder by size and the holder with the biggest bet aren't always the same fund.

California State Teachers Retirement System has added to its KOS position for two straight quarters, increasing it by $727.4M to reach $727.8M today.

Raymond James Financial Inc has trimmed its KOS position for two straight quarters, cutting it by $696.0K while still holding $106.1K.

KOS is up 3.2% today, and institutions have been net buyers of $124.3M this quarter — today's price move and the underlying institutional flow are pointing the same direction.

KOS reported a net loss of $542.2M over the trailing twelve months.
