Liu Qiang, the master of Xiaoyao, left his job because of the stock crash. From Liu Qiang's book The Story of the Futures Master, we know that the direct cause of crushing Liu Qiang is the stock market crash that started on June 15. People familiar with the matter said that when the market fell below the 60-day moving average in the middle and late June, Liu Qiang went against his consistent investment philosophy, bought multiple stock index futures at a high level, and even allocated funds at the bottom to buy stocks, which eventually broke the position.
