I dont know if I should go back and buy that stock. Its looking like a good time right now
That's up to you.
If you know that stock well and think it will rise in the future, then I would buy and hold (don't sell if it drops, maybe add more).
If you are only speculating, then you are basically just chasing momentum, and that's luck or gambling if you win or lose.
When I play using FOMO, I usually lose, so I don't chase. Others like hmgROCK might have better luck chasing, but not me.
For example, when oil was down I bought OXY at $11, it went to $15, I didn't sell. Then went back down to $12, I bought a bunch more.
Now it is at $20+. And I'm expecting it to go to $40+.
By staying strong, it's already paying off. $1k+ today.
