Twitter shares were hammered after the company reported no gain in its user base in the past quarter, at 328 million monthly active users.
It reported a net loss of US$116 million (S$157.5 million) in the second quarter, slightly wider than its US$107 million loss for the same period last year.
Amazon reported that profit for the second quarter plunged 77 per cent, although its revenue grew 25 per cent from last year to US$38 billion.

"The US dollar index rebounded last night as the euro retraced from its three-year high due to profit-taking activities. If tonight's GDP data shows strength in the US economy, the dollar could be supported, and set for a rebound," she said.
