BloombergThe earliest-available indicators of China’s economic performance pointed to a continued slowdown this month. Profits at Chinese industrial firms fell the most on record last month, dropping 9.9 percent from a year earlier, data from the Chinese National Bureau of Statistics showed yesterday. The decline in prices at the factory gate is one of the factors undercutting those profits and is expected to continue this month, according to a Bloomberg tracker of producer prices. If those deflationary effects continue, it would further hurt corporate profits at home, and eventually drag down prices and profits overseas. Warren Buffett-backed BYD Co (比亞迪), China’s biggest maker of new-energy vehicles, last month reported an 89 percent slump in third-quarter earnings and said that profit could fall as much as 43 percent this year.
