if there are a lot of people buying and selling stock in the Chinese stock market , the Chinese stock market would come close to be perfect competition, which means there is chance that there is little money to be made..if the price reflects accurately what a person is willing to pay then how is someone suppose to make money out of others expectation. so if the Chinese are letting ordinary people trade stocks..i am guessing the return on stocks going to decline..i know it does not look like that but i am guessing..we will see what happens..hehe..
