If the recent developments in the markets hold and fear dissipates, I think a play on Hang Seng index would be terrific opportunity. To be sure, I am still expecting a slight pull back to around 18500.
This index is peculiar in the sense it has some good correlation with China but is not as violent as CSI index.
For someone with high risk appetite, this should work well. Some risk money could be allocated here.
Note: This is not exactly a China play. It's more of decoupling from the ridiculously elevated level of coupling play.
