I added to my holding this morning. I wanted to buy more than what was on the 81c offer (there were only about 3k on offer). I expected to see it bid over at 81c, and have to wait a few hours to get filled. I put the order on and in the split second it took me to get back to my original screen, I was filled. Bots at play. Absolutely no idea what to read into it. Seems to be common for dual listed stocks.
Re the quarterly... I gave it a 7 out of 10, hence happy to top up my holding (aka average down).
