Over here, I've gathered a list of chinese stocks which are optionable. A few of them are single digit dollar stocks and they have triple digit volatility(!)
The above list is not a recommendation but rather to provide you with a smaller universe to start your research with should you decide to option trade chinese stocks. Bear in mind that there is some element of speculation going on in some of these chinese stocks. So do exercise due diligence and as always, proper risk management.
