Amarin Corp Plc (AMRN)

Still confused why NASDAQ.com would show a -19M sale if nothing of the sort happened - that link in Sleven's post 402979 is where I saw this first before I started digging deeper. I didn't find Birdrock's SEC form showing on Sarissa's Q4 13F that they owned 4.8M shrs, but did see it on other websites. Still don't understand why Whalewisdom shows the 4.8M shrs for Q4 13F but current combined 13D/F/G is 25.2M shrs.

Didn't mean to post FUD, but I've never seen anything like that before, where 13F holdings is so far off from combined holdings. This goes beyond AMRN and Denner - how many other stocks out there have investors been mislead about because of reported ownership discrepancies like this? I mean what is the only true source for this info, as the multiple sites I checked (at least 6) were about 50:50 accurate on actual ownership as of 12/31/22 and 1/11/23?
