Tesla might have more luck on the utility side.

"Tesla, we think, is a classic example of people becoming too excited about a fast-growing company and overpricing the stock by a huge margin," said Thompson.
Langan also added that he was cautious on the long run.
"We are neutral on the stock and a lot of that is because there is going to be a lot of challenges, obviously on the car side," Langan said. "Getting battery cost down is key, but on the stationary storage side there is a lot of questions about which chemistry will dominate long term. It might not be lithium."
