Check out the latest calls and chatter below. 5:37 a.m. ET: Piper Sandler upgrades Sunnova, Sunrun Renewable energy companies Sunrun and Sunnova could benefit from the Federal Reserve’s “pivot,” according to Piper Sandler. The firm upgraded shares of the two solar companies to overweight from neutral. Analyst Kashy Harrison thinks the three rate cuts the Fed indicated at its last policy meeting could be a key theme for the two solar companies. The renewable energy sector is highly sensitive to rates, meaning that Sunrun and Sunnova have struggled this year and are down 24.9% and 26.9%, respectively. RUN NOVA YTD mountain RUN and NOVA in 2023 “While the Fed pivot is undoubtedly positive, it is no ex-machina for all of our coverage’s 2023 challenges and some sub-sectors benefit more than others. We view the resi installers as the largest/immediate beneficiaries of lower rates,” Harrison wrote, referring to the two companies. Harrison raised her price target on Sunnova shares to $26 from $13, suggesting shares could essentially double from Monday’s close. She also increased her price target on Sunrun to $31 from $15, implying nearly 72% upside potential. “With lower rates, we expect equity appreciation given asset valuation sensitivity to rates,” Harrison added. — Hakyung Kim 5:37 a.m. ET: Jefferies says buy Elanco The firm initiated coverage of the pets pharmaceutical stock with a buy rating and a price target of $17, implying upside of 24% over the next 12 months. Elanco shares have lagged the broader market this year, rising just 11.9% in that time, while the S & P 500 is up 23.5%. However, analyst Glen Santangelo thinks potential “blockbuster launches, coupled w/improving execution, creates an attractive setup into ’24 against backdrop of a discounted valuation.” “We see ELAN entering 2024 w/ increased optimism given a multitude of impending product launches (Zenrelia, Credelio Quattro, Bovaer),” he said. Zenrelia is a product used in canine dermatology, while Credelio Quattro fights off ticks and kills fleas. Bovaer is a cow feed that looks to reduce methane emissions. “We expect this pipeline to bolster the recent inflection to growth and are encouraged by mgmt’s commitment to growth in 4Q and 2024,” Santangelo said. “[Long-term] we think these launches could improve the product mix … driving both rev growth and margin expansion.” — Fred Imbert
