Goldman Sachs analyst Ben Hartwright upgraded China Southern Airlines (ZNH) to Buy from Neutral with a price target of HK$6.70, up from HK$6.60. The analyst also reiterates a Buy rating on Air China (AIRYY) and maintains a Buy rating on China Eastern Airlines (CEA). His new 12-month price targets offer 38%-60% upside potential. Hartwright continues to be positive on Chinese airlines, as he believes supply growth "should be kept in check" due to airspace capacity constraints and the Boeing (BA) 737 MAX groundings. The analyst also sees a demand recovery supported by "recent strong loosening signals" in China, and expects a lower oil price in Q4 relative to last year.

Barclays analyst David Strauss lowered the firm's price target on Boeing to $190 from $235 and keeps an Equal Weight rating on the shares. The company reported 13 total deliveries in Q1, four storage and nine off line, the analyst tells investors in a research note.
