Quantitative Models and Construction Methods 1. Model Name: Rotation Model - **Model Construction Idea**: The model is based on the relative performance of micro-cap stocks and "Mao Index" (a large-cap index), using rolling slopes and relative net values to determine rotation signals[19][24] - **Model Construction Process**: 1. Calculate the relative net value of micro-cap stocks to the Mao Index. If the relative net value is above its 243-day moving average, the model prefers micro-cap stocks; otherwise, it prefers the Mao Index[19][24] 2. Compute the 20-day closing price slopes for both micro-cap stocks and the Mao Index. If the slopes diverge and one is positive, the model selects the index with the positive slope to adapt to potential style shifts[19][24] 3. Timing indicators include the 10-year government bond yield (threshold: 0.3) and micro-cap stock volatility crowding (threshold: 0.55). If either indicator hits the threshold, a closing signal is triggered[19][24] - **Model Evaluation**: The model effectively captures style rotation signals and provides a systematic approach to manage risk and optimize returns[19][24] 2. Model Name: Macro Timing Model - **Model Construction Idea**: This model integrates macroeconomic growth and monetary liquidity signals to determine equity allocation levels[44][45] - **Model Construction Process**: 1. Assign signal strengths to economic growth and monetary liquidity dimensions. For December, the signal strengths were 50% and 60%, respectively[45] 2. Combine these signals to recommend an equity allocation level. For December, the recommended equity allocation was 55%[45] 3. The model's performance is tracked, with a year-to-date return of 13.57% compared to a 25.65% return for the Wind All-A Index[44] - **Model Evaluation**: The model provides a balanced approach to equity allocation, leveraging macroeconomic indicators to guide investment decisions[44][45] --- Model Backtesting Results 1. Rotation Model - **Relative Net Value**: Micro-cap stocks to Mao Index relative net value was 2.06, above the 243-day moving average of 1.80[19] - **20-Day Slope**: Micro-cap stocks' 20-day slope was -0.15%, while the Mao Index's slope was 0.00%[19] - **Risk Indicators**: Volatility crowding was -17.17%, below the 55% risk threshold; 10-year government bond yield was 7.32%, below the 30% risk threshold[19] 2. Macro Timing Model - **Economic Growth Signal**: 50%[45] - **Monetary Liquidity Signal**: 60%[45] - **Equity Allocation**: 55%[45] - **Year-to-Date Return**: 13.57% (compared to Wind All-A Index's 25.65%)[44] --- Quantitative Factors and Construction Methods 1. Factor Name: Growth Factor - **Factor Construction Idea**: Measures the growth potential of companies based on financial metrics like net income and operating income growth[58][59] - **Factor Construction Process**: 1. Use single-quarter net income year-over-year growth (NetIncome_SQ_Chg1Y) and single-quarter operating income year-over-year growth (OperatingIncome_SQ_Chg1Y) as key metrics[59] 2. Combine these metrics to rank stocks and construct the factor[59] - **Factor Evaluation**: Demonstrated strong performance with an IC mean of 10.62% across all A-shares[48] 2. Factor Name: Consensus Expectation Factor - **Factor Construction Idea**: Captures market sentiment and expectations based on analysts' forecasts[58][59] - **Factor Construction Process**: 1. Use metrics like expected ROE changes over the past three months (ROE_FTTM_Chg3M) and target return over 180 days (TargetReturn_180D)[59] 2. Rank stocks based on these metrics to construct the factor[59] - **Factor Evaluation**: Performed well with an IC mean of 9.57% across all A-shares[48] 3. Factor Name: Volatility Factor - **Factor Construction Idea**: Measures stock price stability and risk using historical price and volume data[58][59] - **Factor Construction Process**: 1. Use metrics like 60-day return volatility (Volatility_60D) and CAPM residual volatility (IV_CAPM)[59] 2. Rank stocks inversely based on these metrics to construct the factor[59] - **Factor Evaluation**: Underperformed with an IC mean of -20.21% across all A-shares[48] --- Factor Backtesting Results 1. Growth Factor - **IC Mean**: 10.62% (all A-shares)[48] - **Multi-Long-Short Portfolio Return**: 20.54% (all A-shares, year-to-date)[49] 2. Consensus Expectation Factor - **IC Mean**: 9.57% (all A-shares)[48] - **Multi-Long-Short Portfolio Return**: 15.95% (all A-shares, year-to-date)[49] 3. Volatility Factor - **IC Mean**: -20.21% (all A-shares)[48] - **Multi-Long-Short Portfolio Return**: -2.96% (all A-shares, year-to-date)[49]

一、行情速览：4300股下跌！但这两大板块逆市大涨，背后逻辑很硬核 今天（12月16日）的A股，用四个字形容：跌多涨少。收盘一看，几大指数"绿得"整齐：沪指跌 1.11%，深成指跌1.51%，创业板更是大跌超2%。全市场超过4300只股票下跌，赚钱效应挺差，成交额 维持在1.75万亿的高位。 但是！如果你只看到"普跌"，那就错过关键了。市场内部冰火两重天，资金正在用脚投票，进行一场激 烈的"高低切换"。 1. 智能驾驶：终于拿到"准生证"，行情性质可能变了！ 为什么太"聪明"反而容易吃亏？ 今天最大的亮点。驱动因素就一个：工信部正式发放了国内首批L3级自动驾驶的准入许可。这事儿意 义重大，意味着智能驾驶从过去的"概念讲故事"，迈进了"产品可上路、商业可落地"的实质阶段。有国 家政策给技术安全性背书，产业链从整车到雷达、算法的公司，业绩兑现的节奏可能会大幅加快。所 以，资金的追捧，是在押注一个产业从"0到1"进入"1到N"的爆发拐点。 2. 零售消费：防守+政策预期，成了资金的"避风港" 在市场整体慌的时候，资金最爱往哪里跑？业绩稳、估值低、还有政策撑腰的地方。零售板块今天就是 典型。一方面，三部门刚发文要加大 ...

这两条信息结合在一起，透露了一个清晰的信号：市场正在从一个纯粹由流动性和未来想象驱动的阶 段，逐步转向一个需要兼顾估值、盈利基本面和实际经济数据的阶段。 本周即将密集公布的美国零售 销售、非农就业和CPI数据，就是检验这一转变的关键试金石。 那么，这对我们A股投资者有什么具体启示呢？我认为有三点值得重点思考。 第一，重视板块间的轮动与再平衡。美股资金从高估值科技股流向更广泛标的，这种风格偏好很可能通 过情绪和全球配置影响A股。这意味着，我们在关注科技主线的同时，必须高度重视那些估值处于低 位、受益于经济复苏预期的方向。 第二，"业绩确定性"的权重正在提升。当流动性最宽松的预期逐步被市场消化后，无论是美股还是A 股，资金都会更敏锐地寻找那些业绩能实实在在兑现的行业和公司。故事依然重要，但故事的实现能力 变得更加重要。 第三，做好应对波动的准备。重磅经济数据集中公布，必然会加剧市场的短期波动。对于中长线投资者 而言，这非但不是风险，反而可能是检验手中公司成色、逢低布局优质资产的观察窗口。 朋友们，我是帮主郑重。周一晚上，美股又给全球市场出了一道思考题：纳斯达克指数跌了超过130 点，科技股普遍承压。但更有意思的， ...

2025年港股步入估值修复与结构重塑并行阶段，估值低估、资金错位与业绩分化成为核心特征。历经此 前三年调整，恒生指数形成显著的估值洼地，南向资金创纪录净流入与外资转向共同重塑资金格局。 日前，中信证券海外策略首席分析师徐广鸿在接受中国证券报记者专访时表示，2026年港股将在政策红 利与外部风险博弈中开启第二轮估值修复，内外因素共振有望进一步打开上行空间。在此背景下，投资 需紧扣"业绩确定性+估值弹性"主线，科技、医药、资源品与必选消费四大赛道，凭借政策支撑、产业 景气或供需优势，成为把握港股修复行情的核心方向。 美联储政策成为短期最大变量，徐广鸿认为，市场对12月"鹰派"降息存在担忧，但机构判断此次议息会 议或为"鹰派"恐慌顶点，后续随着美联储主席提名博弈展开，若未出现极端"鹰派"候选人，市场将重回 宽松交易逻辑。 估值洼地凸显 今年以来，港股三大指数震荡上行。Wind数据显示，截至12月9日，恒生指数、恒生中国企业指数、恒 生科技指数分别累计涨幅为49.20%、22.59%、24.32%。 "当前港股正处于估值修复与结构重塑的关键阶段，估值低估、资金错位与业绩分化构成市场核心特 征。"徐广鸿表示，从估值维度 ...
