As previously reported, KeyBanc analyst Sophie Karp initiated Vivint Solar with an Overweight rating and $12 price target. The analyst notes that the company dealt with some growing pains in 2018, and as it returned to profitable growth in 2019, the shares reacted positively, outperforming the peers and the index by a wide margin. Despite the year to date outperformance, Vivint Solar still trades at a discount to the value of its existing portfolio - creating an attractive margin of safety since, at these levels, investors essentially pay nothing for the growth, she contends.
