Look at what happened recently with BSL.
SPP at $1.55 substantial discount.
Shares dropped about 20 cents say from $2.70 to $2.50.
Currently $2.60.
Sure some took profit but most realise this is a counter cycle play and will be rewarded down the track.
As for PBG.
IMO opinion I would not buy today.
Once the new shares hit trader's accounts I would estimate that you could buy in the 70-75 cent range as some do look to lock in profit.
