I think Crown Castle is absolutely a long term hold and a buy especially considering the infrastructure needed to build the 5G network.
It looks like it is forming a bearish wedge but is staying within the trendlines. We had a break of the high and it tested the trendline twice before it retracted. Overall, the MACD and RSI divergence does not look too great to me. I am looking for the 168.75 level to hold as support. We'll see what happens.
Not financial advice. Trade at your own risk. Good Luck!
