(... I'm well-informed? are you confusing me with @InvisibleJim maybe?)

It seems fairly clear to me that it would definitely been worth investing in a Chinese ETF at this time...but Meb Faber would suggest that it would be wisest to spread risk by investing in ten national ETFs with the lowest CAPEs...(and I think China would almost certainly be one of those 10 at the moment).

This is not something I am going to do any time soon though.
