Film and Entertainment Sector - The film and entertainment sector faced substantial drops, with DMG Entertainment down by 9% and Maoyan Entertainment falling over 7%, hitting new lows. According to a report from CICC, the effective box office for the first six days of the 2026 Spring Festival was 5.077 billion yuan, a decrease of 38.7% compared to the previous year. The expected box office for the period may fall below the previously anticipated range of 6.5 to 8.5 billion yuan due to a lack of leading films [3]. Tourism and Retail Sector - The tourism and retail sector also declined, with China Duty Free Group dropping over 8%. During the first five days of the Spring Festival holiday, duty-free shopping in Hainan reached 1.38 billion yuan, with 177,000 shoppers, representing increases of 19% and 24.6% year-on-year, respectively. However, the stock price of China Duty Free has largely reflected this demand [3]. Semiconductor Sector - The semiconductor and memory stocks showed resilience, with Hynix reporting strong demand from AI clients and limited supply, leading to continued price increases in memory products. Hynix indicated that its inventory for DRAM and NAND is only about four weeks, and it expects this level to continue to decline throughout the year [4]. AI Applications - AI application companies, particularly Zhiyuan and MINIMAX-WP, performed strongly, with Zhiyuan rising nearly 21% and MINIMAX-WP up nearly 8%. Reports indicate that Chinese large models are capturing a significant share of the global developer market, with Chinese models accounting for 61% of the total token volume [4].
