@Enea91 There is a reason why the market sends a share to the ATL. That's why I see no reason whatsoever not to buy a share at the ATH. After the ATL / ATH is before the new ATL / ATH.
I'm not a fan of chart analysis at all, but a share at the ATL without a recognizable countermovement ... That can go well, of course, but it can also backfire big time.
In summary, the risk/return ratio would be too bad for me.
