ENPH and INMD. Slowly building small positions.

I bought 2 shares ENPH last week cause it had sold off a lot this year and of course had a huge return last 5 years.

I see after earnings tonight it's up 14% so far. Would I be better to wait to add a little more after such a run up?

Also my INMD position is about 1.5% and I'm in at $66, so I'm a little red right now.

INMD reports on Thursday and I'm thinking of adding a short tern small position on my ROTH and then selling it if it jumps on earnings.

My long inmd position (about 1.5%) is in taxable and a long hold.

Thoughts?
