Mysterious helmeted one, I believe you are correct. I think there was general confusion today - not sure about other platforms but for me on CommSec there was no indication of an announcement either on the old MPJ tickers, nor the temporary MPJDA and MPJDB. Further, my portfolio only showed MPJ and MPJO, with a market value of zero for both. Terrible timing for the release of a really good announcement.
Hopefully there will be a bit more awareness of it tomorrow, and by next week we might see some price movements that reflect the string pipeline of coming news.
