KeyBanc upgraded Sunrun (NASDAQ:RUN) to Overweight from Sector Weight with a $27 price target, based on the company's attractive valuation, strong data from CA, and its view that residential solar firms have a significant pricing power to execute in the higher interest rate environment.

KeyBanc noted that residential solar company shares, such as Sunrun, have significantly underperformed during the tightening cycle. Although the shares have been noticeably cheap for some time, analysts believe that the worst of the tightening cycle appears to have passed, indicating that the sentiment should reach its lowest point at current levels.

Moreover, KeyBanc has a positive outlook on the company's fundamentals and expects that multiple concerns arising from California regulatory changes and rate volatility will start to dissipate in the near term.
