Seen similar with the REITs around end of month option time.
I think MOF or MCW did a 10 million buy order in close which jumped it 30% a couple of months ago, Dec?
I've also seen 10 million odd orders being used to do end of month manipulation - 10 million buy at 1 price , 10 million sell a couple of cents lower and then move that around to achieve the desired price.
Typically followed by XT transactions after close. Given the XT I'd say it's just manipulation and drop pretty quickly tomorrow morning. Lucky to hold the price at the open.
