Market Observation - The Shanghai Composite Index experienced narrow fluctuations on January 8, with the ChiNext Index dropping over 1% during the session. The total trading volume in the Shanghai and Shenzhen markets was 2.8 trillion yuan, a decrease of 53.8 billion yuan compared to the previous trading day, marking the fourth consecutive day of trading volume exceeding 2.5 trillion yuan. By the close, the Shanghai Composite Index fell by 0.07%, the Shenzhen Component Index by 0.51%, and the ChiNext Index by 0.82% [1]. Sector Performance - The commercial aerospace sector has seen a resurgence, highlighted by the recent groundbreaking of a large liquid rocket assembly and recovery reuse base by Arrow Yuan Technology in Qiantang. This marks the establishment of China's first offshore recovery reusable rocket production base and the launch of the first stainless steel rocket super factory [2]. Commodity Market Dynamics - Experts warn that investors are now living in a new era of geopolitical risk, which has increasingly influenced commodity pricing mechanisms. The ongoing conflicts, from Ukraine to Venezuela, have impacted the prices of oil, gold, copper, and other commodities. Oxford Economics noted that geopolitical risks are becoming a persistent pricing factor rather than a temporary shock, with markets now incorporating a fixed risk premium reflecting supply chain vulnerabilities and resource nationalism [3][4].
