ENPH. In at $150 afraid to add…..

I bought ENPH at $150 but on bought 5 shares in my ROTH at the time. Well the darn thing keeps going higher! Not that I'm complaining lol!

I've been waiting for it to come down some to add more to it, but feel over $200 it's not a buy?

Would you add a couple more shares now or wait for a market decline?

I thing long term this is a good one, but I also feel the market may sell down 20% soon and I can get in cheaper.
