China's flash HSBC PMI for April slides to 50.5, missing expectations by a full point and against March's read of 51.6. "New export orders contracted after a temporary rebound in March, suggesting external demand for China's exporters remain weak," says HSBC. "Weaker overall demand has also started to weigh on employment in the manufacturing sector." Shanghai (FXI, CAF) is off 1.5 in early trade. Hong Kong (EWH) -0.9%.
