the sentiment was that the government will prop up the market before the olympics to create stability and "happiness", so the market should raise before the olympics, then followed by a major selloff after the games end.
Of course the government didnt do shit to help the financials, and the market didnt go up before the olympics. So at this point, it's like flipping a coin. Many "analyst" are now saying after the game as the country returns back to normal the market will then raise.
China (shanghai) stocks are extremely volatile, even the index, if you try to apply the same technical used in the us market to it you will be whipsawed to death in no time.
I got in a small position on the etf50 index after a 55% drop from the bull run highs partly to hedge against the usd, will probably hold it for 10+ years as i believe china is now in the same stage as the US in 1970-80s. There will be bear periods, but the growth potential is still tremendous in the next 20 years.
