LCQ: the competitiveness of the Hong Kong stock exchange
HK Government, 6-Apr-2011
Comment: nothing prevents a "flash crash" in HK, and indeed we had a mini-version of this in HSBC on 9-Mar-2009. There are no circuit-breakers on SEHK. Regarding trading spreads, HKEx U-turned on that in 2007 and there has been no progress since then.
