Define what you mean by a 'scam' in this context. For example, are you alluding to misreporting of facts in the companies reporting? Misappropriation of company funds by a director? I suspect you're thinking something along the lines of Sino-Forest, and Carson Block and his Muddy Waters Research.
Whilst Hong Kong does have have occasional rogue companies and their officers exposed for wrongdoing, the majority of these are mainland Chinese companies, and frequently listed on the second tier market (GEM) rather than main board.
It seems to me that most of the recent cases of Chinese companies revealed to have over-inflated or non-existent assets, loans to directors for personal projects etc., are those listed on Nasdaq or TSX. They listed there because it was easier to pass scrutiny, which doesn't say much for US regs.
If a company is listed on HKex and its shares are actively trading (meaning, not suspended), then that means there are no red or yellow flags as far as the regulators are concerned. Beyond that you'd have to do your own digging by searching Google etc., for adverse comment.
