It looks to me like some in China were spooked by the low volume and slow decline in the west on Saturday. Enough was dumped when china woke up to exacerbate this and now it seems the mania is beginning to come to an end, it's been losing steam for a good few days now. We've been lucky so far, two major events (Chinese adoption, US senate approval) synergised to boost confidence, adoption and media coverage. Unless new money enters the market soon I expect the bears will have the upper hand for a while.
Tomorrow is crucial, if there's going to be a major correction I expect it then, but I can't see a 'Great Crash'. The events that prompted this rally are real and game-changing, long term is looking better than ever
