People will tell you to buy at ATHs and after every red candle, stop listening to them
If you’re buying $MU after a massive run and think one red day suddenly means it’s a safe dip buy, you probably shouldn’t be chasing it. A lot of these momentum names don’t bottom in one candle, first bounce can easily just be a dead cat bounce before another flush lower the next day.. this sub treats every red candle after ATH like it’s a guaranteed bounce + buying opportunity
if you’re buying near ATHs that’s on you, you should already be okay with the possibility of being down another 10% without losing your mind. Fomo buying only works if you actually accept the volatility before entering, not after it starts dropping. So to answer your question, sometimes doing nothing is healthier than forcing an entry just because everyone else is talking about it.
