On Thursday, the Shanghai Composite Index experienced a modest increase of 0.2%, reaching above 4,120, while the Shenzhen Component Index saw a slight decline of 0.1%, settling at 12,245. This divergence in performance among mainland stocks occurred amidst a growing regulatory crackdown on trading activities. Earlier in the week, China's securities regulator imposed a substantial fine of approximately $12 million on a social media influencer for engaging in market manipulation, emphasizing a stricter stance on online market misconduct. In addition, authorities targeted high-frequency trading and heightened margin requirements. Despite these regulatory developments, investors remain optimistic that the Chinese government will implement new fiscal and monetary stimulus measures within the year to bolster economic growth. In terms of individual stock performers, Montage Technology increased by 3.7%, China Aerospace saw a 7.9% rise, and China Greatwall advanced by 5.6%. Conversely, Giga Device Semiconductor decreased by 2%, TBEA Co fell by 2.6%, and JCET Group declined by 5.3%, negatively impacting the indices.
