China's industrial profits soared last month, helped by favorable year-ago comparisons and a raft of stimulus measures aimed at reinvigorating an economy that has struggled with deflationary concerns. Profits jumped 29.5 percent, sharply accelerating from October, according to official data published yesterday. Companies also recorded large investment returns in November, further boosting their bottom line, the National Bureau of Statistics said. Despite initial expectations that lifting the curbs would see the economy roar back to life, profits for China's big industrial companies from January-November were still down 4.4 percent, although that's eased from a 7.8 percent decline through the first 10 months. The profit data adds to mixed signals on the economy.
