$NIO Inc.(NIO)$ I've in this stock since $8.15.....I saw it go down to sub $2, then back up to $66. My average price is $13.40.... never have i thought about selling...... rarely has this stock provided negative news...... but on good/great news do we ever rise & hold it. I'm not an expert investor but someone just trying to have a middle-class retirement. Do I hold, or take my much lower profits?
