I need to ask the question but isn't that practise illegal, and unethical when a large player tries to do that as they're obviously privy to important information that we or the general market have not yet known about. Just to illustrate, UBS is one of Mercedes formula 1 corporate partners so could a large % of those shares that were accumulated early from 80 cents and during the steep rise and then sold/dumped have this banks hallmarks? Im trying to understand this as this SP action as very unusual and only big funds can buy / sell huge volumes. Broker reports will reveal this. It's unnerving as I also have been at the high end of a trade in the past but luckily got out.
