A new link allowing cross-border stock buying between Hong Kong and the southern Chinese city of Shenzhen made a low-key debut on Monday, mirroring a weak start to the week for markets throughout Asia, Caixin writes. Trading volume over the Shenzhen-Hong Kong Stock Connect was slow on its first day, with only a small fraction of the daily allotted quota in both directions being used. Money flowing from Hong Kong to the Shenzhen stock market totaled 2.7 billion yuan ($392 million) – or just 21% of the total allowed. Money flowing the other way totaled HK$902 million ($116 million), or an even-smaller 8% of the maximum allowable daily volume. The sluggish debut mirrored a similarly weak start to the week for markets across Asia.
