This has been happening almost daily. Sometimes the MMs buy a trivial amount of shares to start the day (like around 480 shares a few days ago on the US side) at a much higher price than the last close, so they could induce the FOMO crowd to buy the shares they immediately start dumping at a slightly lower price.

Perhaps that was an artifact of the warrant overhang and those selling to buy. Let's hope that's done with.
