dead cat bounce, page-9

I Just noticed the difference in BHP and RIO for London versus here. They fell by 1.84% and 1.27% respectively last night.

BHP in Australia $36.65
BHP in London $32.96
Difference 11.2 percent

RIO Tinto in Australia $115.50
RIO Tinto in London $104.45
Difference 10.6 percent

Has anyone here noticed this before. Surely there must be some people arbitraging this. I am staying short the ASX200 for now. I see further weakness in the resources sector especially given these numbers.
