Hong Kong’s stock-market liquidity task force will hold its first meeting this week to study methods to expand capital sources and flows, attract more high-quality listings and boost efficiency and competitiveness, the city’s financial secretary Paul Chan wrote in a blog Sunday.

Lowering stamp duty on transactions isn’t enough to stimulate long-term trading, Chan wrote, citing historical data. The key “is to let investors feel optimistic about the outlook,” he said. “This depends on economic performance, company earnings, the pipeline of potential company listings and so on.”
