The Chinese economy is supposed to be skipping along nicely down the road to recovery. Yet you wouldn’t know it from earnings forecasts – few upgrades have been made since the third quarter of last year. And over the weekend ZTE warned that it expected a full-year loss of up to 2.9 billion yuan ($463-million) for 2012. Back in October, China’s second-largest telecom equipment maker, which depends on the home market for almost half its sales, said it hoped to break even. It comes after another profit warning from TCL Communication, a mobile phone maker, this month. Comba, a larger peer, is expected to follow suit.
