You should never anchor yourself like that, but I do know why you want to do it. The $5 is history and unless we get a brand new pandemic, it may not ever be seen again. As for the $29. If it goes to $100, it will be a bargain price and if it goes to $15 you overpaid. The important point here is only the future can determine the merits of $29 not the past.Truely an impressive come back!
In any case, knowing it hit $5 in April, I am not in a hurry to buy at $29.
All that said, I did not buy anymore today either... but I am aware I may regret that.
