It appears this has been going on since the start of the year. The posted numbers given on institutional ownership are lagging and do not reflect activity from the last update on the various exchanges that track them. Much happens in the timeframe those are posted and now. The last update to most were at Q3'18 close. We will start getting the next batch soon but that will only reflect Q4'18 end.
It will not reflect the start of Q1'19 to present until Q1'19 is closed. Always a lag in official data. This also goes for short interest too.
They make it hard to put the pieces together.
