The Divi has been PRed, there is nothing else to write home about it. The date is the end of the trading day on the 17th of December, although that is probably the date in which the shares must be settled, so realisticly 13th or 14th at the latest to qualify. After that who knows when you will see the shares in BNPD, that is a whole different story and likely not to be sorted out for months.
Once again how do you expect it to run when the company is pouring shares into the float even as we speak now? There are more shares than any amount of volume left in this thing can handle. Yesterday was the highest volume ever and it traded down to a new low.
