The below is from an email Sam sent me so clearly the TDF is a factor to some degree!
"As you will know there are a lot of moving parts to get HBR out and Navitas in Harbour/FIG/TDF/RKH/Navitas Plainly we are still hopeful to get all this over the line but itās not all in our own hands"
As it is reported after market has closed it just shows the bid and ask at that point. Likelihood is that trade has been accumulating over the last couple of days.
