缺芯,本田工厂继续停产
半导体芯闻· 2026-01-05 10:13
安世半导体出现发货延迟后,日本汽车制造商本田称因晶片库存不足,此前已停产的三家中国工厂 复工时间推迟两周至1月19日。 综合路透社和日经新闻报道,日本第二大汽车制造商本田发言人星期一(1月5日)宣布,受晶片 库存不足影响,三座与广汽集团共同运营的停产工厂,复工时间将从原计划的星期一推迟至1月19 日,凸显车商持续存在的供应链压力。 据悉,此次停产始于2025年12月29日,最初计划停产五天至今年1月2日,后因晶片供应问题未 缓解,复工时间两度延后,目前燃油车型生产线将持续停至1月16日。 本田此番宣布紧随闻泰旗下的荷兰安世半导体出现发货延迟,这一问题过去几个月已迫使部分汽车 制造商大幅削减产量。 不过,本田没有将此次复工延后直接归因于安世半导体。去年10月底至11月期间,本田也因为晶 片短缺,而令其在北美的工厂停产或减产。 作为本田在华核心生产基地,三家工厂的停摆时间延长预计将造成上万辆产能缺口,热门车型交付 周期已从原本的一至两周拉长至两至三个月,部分稀缺配置车型提车时间或超一个月。 资料显示,安世的总部位于荷兰,2019年12月被中国公司闻泰科技收购,此后一直向全球制造商 供应基础但不可或缺的芯片。 9月 ...
量化观市:内稳外缓信号确立,跨年行情如何布局?

- The report discusses a rotation model for micro-cap stocks, which uses the relative net value of micro-cap stocks to the "Mao Index" as a key indicator. If the relative net value is above its 243-day moving average, it suggests investing in micro-cap stocks; otherwise, it suggests investing in the Mao Index. Additionally, the 20-day closing price slope of both indices is used to determine potential style shifts. When the slopes diverge and one is positive, the model recommends investing in the index with a positive slope[17][24][29] - A timing risk control indicator is constructed based on the 10-year government bond yield (threshold: 0.3) and the volatility crowding degree of micro-cap stocks (threshold: 0.55). If either indicator reaches its threshold, a closing signal is triggered[17][24][29] - The report evaluates eight major stock selection factors across different stock pools (All A-shares, CSI 300, CSI 500, and CSI 1000). Among these, technical factors (IC mean: 9.30%) and volatility factors (IC mean: 6.86%) performed well, while consensus expectation factors (IC mean: -3.20%) and market capitalization factors (IC mean: -2.71%) showed weaker performance[44][45][46] - For convertible bonds, the report constructs quantitative bond selection factors, including equity-related factors (e.g., equity growth and financial quality) and valuation factors (e.g., parity and floor premium rates). The IC mean and long-short portfolio net value of these factors are tracked regularly[53][54][57]
