ENPH now at $78 after Q3 earnings call. How much lower can it go? Two weeks ago at $120 it felt like the bottom.

I have watched this stock for years and I only recently bought my shares at $126 after seeing it tank from its ≈ $300 ATH. Now the stock is flirting with costing half of what I thought the bottom was. I do think solar energy will continue to grow but I'm uncertain now whether or not ENPH will be part of that. I don't own any of the other solar stocks like Solar Edge, I specifically am interested in ENPH. Is anyone buying? Ir should I wait two weeks for the price to drop another 20% /s?
