Not sure what's with the personal attack.
I will say it again. GMG has been removed from the FTSE NAREIT Index. This has nothing to do with the "top 20" as you suggest.
This is all publicly available information.
"Up all day and a text book dump into the close" Would actually suggest major selling...as indicated by the 80 million shares that were sold by the index followers...
The good news (in my opinion) and why I am long GMG is that this forced selling event has now passed and the selling pressure that has been on GMG since mid-August may now be reduced.
I also note bond yields have reversed their recent rise which should assist the reversal.

Not that I even need to bother, but for the removal of any doubt.
I'm a full time trader completely self employed and I am LONG GMG... goes to show that maybe you need to take a look at how you process information and biases if you felt so worried by my post which contained nothing but facts and needed to turn it personally.
