Good post, ElithX.   I would sumbit that I think the Fintel site is the better one and I am going to add it to the Link Library.  I think I have posted about it once before, but I wouldn't swear to it.  One thing about updates, though, if I remember correctly the info on the Fintel site is only updated every 3 months.  That would make sense, because I believe the previous update was something like 3 September 2020.

Anyway, I like your suggestion and maybe someone here knows a better way to monitor those Institutional Investors and will post about it.    Okiedo
