Caution returned to the market after a recovery in risk appetite spurred a rebound in Hong Kong stocks alongside global equities. Investors are now gearing up for the coming policy meetings by the US Federal Reserve and the Bank of Japan in the coming weeks, with rate decisions expected to have a pronounced impact on global capital flows.
