客户集中度风险溢价
假设
当一家公司的营收高度依赖少数大客户时，其经营稳定性面临显著风险。一旦核心客户流失、削减订单或谈判压价，公司收入和利润可能急剧下滑。市场通常在客户集中度上升初期未能充分定价该风险，导致股价高估；而在客户结构持续恶化后才反应过度，形成错杀机会。因此，对客户集中度显著上升且缺乏对冲机制的公司应建立空头仓位，而对客户结构持续分散、抗风险能力增强的公司可建立多头仓位。
实施方案
基于客户集中度指标（如前五大客户占总营收比例），使用时序差分算子计算其过去两个季度的变化率。若集中度连续上升且当前值处于历史80%分位以上，则视为高风险信号，赋予负向阿尔法权重；若集中度持续下降且处于20%分位以下，则视为结构优化信号，赋予正向权重。结合营收波动率进行交叉验证，排除因整体业务萎缩导致的“伪分散”情形。
阿尔法因子优化建议
不同行业天然具有不同的客户集中特征（如军工vs快消）。建议采用动态行业中性化处理：在每个申万二级行业内独立计算客户集中度变化的横截面分位数，并仅在行业内进行多空配对。此外，可引入“客户续约率”或“合同剩余期限”等辅助字段作为调节变量，当高集中度伴随高续约保障时，适当削弱空头信号强度，以提升因子特异性与稳健性。
Customer Concentration Risk Premium
Hypothesis
When a company’s revenue is heavily reliant on a small number of major customers, its operational stability faces significant risk. The loss, order reduction, or aggressive price negotiation by a key client can lead to a sharp decline in revenue and profits. Markets often fail to fully price this risk during the early stages of rising customer concentration, resulting in overvaluation; only later—after customer structure deteriorates further—does the market overreact, creating potential mispricing opportunities. Therefore, short positions should be established for companies with markedly increasing customer concentration and insufficient risk mitigation, while long positions are warranted for firms demonstrating sustained customer base diversification and enhanced resilience.
Implementation Plan
Using a customer concentration metric (e.g., revenue share of top five customers), compute its quarter-over-quarter change via a time-series difference operator over the past two quarters. If concentration has risen consecutively and currently exceeds the 80th historical percentile, it is flagged as a high-risk signal and assigned negative alpha weight. Conversely, if concentration has consistently declined and falls below the 20th percentile, it is treated as a structural improvement signal and assigned positive weight. Cross-validate with revenue volatility to exclude “false diversification” caused by overall business contraction.
Alpha Factor Optimization Suggestions
Industries inherently exhibit varying degrees of customer concentration (e.g., defense vs. fast-moving consumer goods). We recommend dynamic sector-neutralization: compute cross-sectional percentiles of customer concentration changes independently within each Level-2 industry classification (e.g., SW sectors) and construct long-short pairs only within the same industry group. Additionally, incorporate auxiliary variables such as “customer renewal rate” or “remaining contract duration” as moderators. When high concentration coexists with strong contractual safeguards, the short signal strength should be attenuated to enhance factor specificity and robustness.

===================== !!! 表达式复杂度约束 !!! =====================
每个因子仅可调用 2-4 个数据字段。
表达式中算术 / 时序 / 分组运算符的总数量≤4（运算符可从给定列表中选择，必要时可自定义运算符），最大化降低过拟合风险，；
若使用ts_op（时序运算符），可从 [1，5，10，20，60，120，250，500] 中选择时间窗口，且窗口需与数据类型的时效性匹配（如 news/sentiment 类数据优先选≤20 的短期窗口，fundamental 类优先选≥60 的中长窗口）；
若使用group_op（分组运算符），可从 [market，sector，industry，subindustry] 中选择组别，且组别需与Alpha逻辑匹配（如行业基本面因子优先选 industry/subindustry 中性化，全市场量价因子优先选 market 中性化）。
*=========================================================================================*
===================== !!! 内在逻辑与有效性约束 !!! =====================
逻辑坚实度：每个Alpha必须具备可验证的经济学底层逻辑，并且存在实证支撑需明确该类逻辑在发达市场（特别是发达国家市场，如美、欧）的历史有效性结论，如具备持续的盈利能力和普适性，能穿越不同市场周期（牛 / 熊 / 震荡市）。
预期表现：每个Alpha的样本内验证标准按长达10年的滚动回测中，应有望表现出高夏普比率、合理换手率、高年化收益率与低回撤的特征。
实施稳健性：每个Alpha能够在实际操作中可靠，对噪音和参数具备鲁棒性。
参数敏感性低：所选时间窗口（如60日与65日）或分组方式（如industry与subindustry）的微小变动不应导致因子排名和绩效发生颠覆性变化。
数据源容错性：对数据源的细小错误（如单日数据缺失、小幅度的定义差异）有较强的抵抗能力，核心信号不会因此失效。
idea独特性
可提供增量信息，可以提供独立于常见风险因子的增量预测能力。
具备低冗余性：其信号逻辑应与Barra等主流风险模型中的风格因子保持较低相关性。
逻辑新颖性：在遵循经典理论的基础上，鼓励通过独特的运算符组合或数据视角，对已知异象进行更精细或更稳健的捕捉。
