- 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]

而在此前，三星等存储巨头将产能优先投向AI服务器所需的HBM（高带宽内存）芯片，导致消费级芯片供应锐减。例如三星32GB DDR5内存芯片价格从 149美元涨至239美元（涨幅60%）。DDR内存芯片广泛应用于服务器、计算机和其他设备中，通过临时存储数据并管理快速数据传输和检索来提升计算性 能。而亚马逊、谷歌等云服务商则通过长期协议锁定大量存储芯片产能，2026年AI基础设施支出预计达6200亿美元，加剧消费端短缺。此前10月小米也对 旗舰产品进行提价，公司总裁卢伟冰曾表示预计2026年面临的供应链压力将"远大于"2025年。 花旗集团分析师Peter Lee曾指出：面对持续的半导体供应链压力与成本上涨，全球主要消费电子制造商已采取差异化的应对策略，其核心在于战略性备货与 审慎的价格传导。可见，芯片短缺无论对生产商和消费者都将是一个严峻的问题。 1月5日消息，三星联席CEO指出内存芯片短缺"前所未有"且"极其严重"，内存芯片价格飙升将"不可避免"推高智能手机价格。据网易科技此前报道，由于人 工智能需求推动存储芯片价格飙升，消费电子产品制造商警告2026年产品价格可能上涨5%至20%。 ...
