In another sign that China's economy is downshifting, an index released on Monday showed China's service sector growth slowing in October to a nine-month low. The bad news followed Saturday's poor showing for manufacturing, which grew at its slowest pace in five months. The service reading, issued by the National Bureau of Statistics and China Federation of Logistics & Purchasing in Beijing, fell to 53.8, from 54 in September. Manufacturing came in at 50.8, down from 51.1 the month before. The economy still faces some headwinds.
