You obviously do not do your homework, understand who is and who isn't regulated in HK nor know who offers access to markets other than the US.

For our financial health - it is no secret that the IB Group is sitting on over $5 BILLION USD in equity capital, financials are reported publicly quarterly and with monthly metrics you can also get a feel for how things are going on the brokerage side.

On September 15, 2008, Lehman Brothers filed for bankruptcy. With $639 billion in assets and $619 billion in debt, Lehman's bankruptcy filing was the largest in history, as its assets far surpassed those of previous bankrupt giants such as WorldCom and Enron.
IB is nothing comparing to what Lehman Bothers used to be.
