Just for old times' sake...27 Apr 2018 15:18
PM's Sp on April 28, 2016 = 2.12p
PM's Sp on May 4, 2016 = 5.75p (weekend in-between)
At that time news broke concerning Shell's/BG's exit from the JV agreement confirming the payment of the $10m exit fee and resulting in PM's 100% ownership of the licensed acreage. Clearly, the market could have reacted differently.
At the very least this proves that the SP can go ballistic on certain news.
Therefore: Grab your asses and get ready for "certain" news as of next Monday.
