"Our US$3.5 billion investments are under way, enabling us to deliver a robust start in Asia this year," Greg Hingston, regional head of wealth and personal banking business, said. "We are seeing increased trading and investment activity from new and experienced investors on mobile and, with our relationship managers and wealth specialists, for more sophisticated needs."
