港股汽车股走低，蔚来跌超6％

Group 1 - The core viewpoint of the articles indicates a significant decline in Hong Kong automotive stocks, particularly among electric vehicle manufacturers, due to a decrease in consumer traffic during the 2026 New Year holiday compared to 2025 [1][2] - NIO, Great Wall Motors, and XPeng Motors saw stock declines of over 6%, nearly 6%, and over 5% respectively, marking new lows since their listings in September 2025 [1] - The decline in consumer traffic is attributed to increased purchasing costs from changes in the new energy vehicle purchase tax policy, leading to a cautious consumer sentiment [1][2] Group 2 - In 2026, the new energy vehicle industry faces two major policy changes: the reduction of the vehicle purchase tax exemption from full exemption to a 5% tax rate, and a shift in subsidy policies from fixed amounts to percentage-based subsidies [2] - Although many automakers have implemented "safety net" measures, these do not fully offset the increased costs from the purchase tax [2] - For example, a consumer purchasing a NIO model priced at 119,800 yuan will incur nearly 6,000 yuan in purchase tax in 2026, while NIO only offers a 2,000 yuan subsidy, resulting in a higher overall cost compared to 2025 [2]
