Analyst Sophie Karp downgraded the Texas-based residential and commercial solar energy company to sector weight from overweight and removed her price target on the stock. Sunnova shares have plunged nearly 75% this year, punished by a higher-for-longer interest rate environment that has been challenging for solar companies’ project financing and cash flows. “The overall residential solar landscape in the U.S. remains challenging due to the combination of lower energy prices and elevated financing costs,” Karp wrote in a Monday note, saying that a lack of encouraging data from the industry suggests that recovery remains elusive. “NOVA specifically is under pressure to demonstrate positive q/q cash movement and to define its capital allocation strategy going forward.” Karp reiterated her sector weight rating on solar peers Sunrun, SolarEdge Technologies and Enphase Energy, meanwhile. — Pia Singh 5:43 a.m.: JPMorgan upgrades Roblox The sell-off in Roblox shares has created a big buying opportunity, according to JPMorgan.

That pullback “presents a compelling entry point for a company growing bookings ~20%+, exiting a heavy investment cycle, and ramping two new revenue streams in advertising (2H24) & commerce (2025),” Carpenter said. Roblox shares popped 3% in the premarket following the upgrade. RBLX 1D mountain Roblox rises — Fred Imbert
