William Blair analyst Nicholas Heymann says Curtiss-Wright remains his multi-industry top pick to outperform in 2019. The analyst attributes the 28% selloff in the stock since mid-September to heightened fears regarding a potential decline in the company's "highly lucrative" China sales starting in 2020 and of possibly slower growth in the U.S. Department of Defense procurement budget for fiscal 2020. However, the anticipated downturn in Curtiss-Wright's China Direct reactor coolant pump sales in 2020 is likely to be largely mitigated by "strong growth" in the company's other nuclear component and service sales to the Department of Defense for upcoming new aircraft carriers and submarine programs, Heymann tells investors in a research note. He expects greater clarity surrounding the company's nuclear components and service and defense business for 2019 and 2020 is forthcoming with the Q4 earnings report. Heymann keeps an Outperform rating on Curtiss-Wright.
