In terms of straight options, there are some very interesting possibilities in the ITM (in-the-money) calls for 2011. These calls are illiquid, but there are market makers to meet your request.
Using the 'ask' price:
The extra premium asked for the options is extremely low. A 25 call option is intrinsically worth $0.47 today. A $24 call option is worth $1.47.
If you believe the Yuan will only appreciate from here, these could be extremely good possibilities. The leverage will be very large.
Please do your own due diligence. This is not advice. Options are very dangerous and may cause 100% loss. Computed with StraddlesCalc Tool
