sure about that. but if you can open a broker account outside of china. seems the chinese market do have a certain corrlation with usa market. what i would do is figure out roughly idea what your house might worth on a monthly or quarterly base, and pull out s&p 500 return for the same period. and do a one factor linear optimization. the factor is based on the value of your house at different time, what is the % of capital you need to short spx. without the past data i don't even know if this is even possible. but at least that would the first approach i would do.
