However, Alibaba has hit back at those claims, arguing that demand will remain robust as its target markets are more affluent and likely to weather a slowdown. Stocks bounced off session lows, though remained in the red, as investors showed their nerves ahead of the two-day Federal Reserve meeting on Wednesday. Members could decide upon their first interest rate hike in nearly a decade. Chico's (CHS) climbed on reports it was considering a sale after being approached by private-equity firm Sycamore Partners.
