The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 1991.6 billion yuan, an increase of 330.9 billion yuan from the previous day [3]. - The communiqué of the Fourth Plenary Session of the 20th CPC Central Committee announced that the main goals during the 15th Five - Year Plan period include significant achievements in high - quality development and a substantial increase in the level of scientific and technological self - reliance. The proportion of the science and technology innovation industry in China's future economy will increase, and corresponding policy support will be introduced. Against the backdrop of positive policy expectations, technology - related stocks rose significantly [3]. - The easing of external uncertainty risk factors brought about by China - US economic and trade consultations led to a recovery in investors' risk appetite, causing the stock indices to rebound from the bottom.
