Stocks fell across the globe as worries over softening demand for the iPhone prompted a tech stock selloff across the world, while the arrest of car boss Carlos Ghosn pulled Nissan and Renault sharply lower. Even China's recent rally fizzled and the Shanghai composite closed down 2.1% near session lows, signalling that the global slump led by tech shares would deepen Tuesday, adding a new layer of pessimism to markets already anxious over trade. Treasuries advanced and the dollar edged higher.

S&P 500 futures traded near session lows, down 0.6% and tracking a fall in European and Asian shares after renewed weakness in the tech sector pushed Nasdaq futures sharply lower for a second day after Monday's 3% plunge and crippled any hopes for dip buying. News around Apple triggered the latest bout of stock market selling, after the Wall Street Journal reported the consumer tech giant is cutting production for its new iPhones.
