Amarin Corp Plc (AMRN)

The 13F tape is quietly getting more constructive. Sarissa’s newest filing (filed Feb 17, 2026) reinforces that Denner remains heavily involved, and that ‘big-holder’ positioning hasn’t vanished — if anything, it continues to consolidate. Meanwhile AMRN still has a meaningful institutional footprint with multiple funds/market makers reporting positions (Sarissa, Acadian, Kynam, MS, Susquehanna, Millennium, Citadel, BNP, etc.). That matters because in a thin-float, post-split stock, it doesn’t take much incremental demand (or a small shift in sentiment into the Q window) to create an air-pocket higher. When the morning is ‘dead’ and the volume looks staged, that’s often the tell: weak hands are being tested for supply before the real bid shows up later in the session.
