About me

我关注 A 股量化研究、风险建模与数值方法。这里不是一张只展示漂亮结果的成绩单,而是一份持续更新的研究航海日志:提出问题、明确假设、实现代码、检查偏差,也如实保留没有通过检验的方向。

  • 🔭 研究兴趣:因子检验、事件驱动、组合构建、尾部风险
  • 🧭 方法偏好:时点一致、口径透明、结果可复核
  • 🧪 研究态度:先证伪,再解释;区分回测表现与可交易结论
  • 🌊 当前航线:A 股策略原型与稳健性验证

Research compass

Question → Point-in-time data → Reproducible code → Robustness checks → Honest limits
  1. 时间一致性 — 尽量只使用决策时点真正可获得的信息。
  2. 成本意识 — 把手续费、滑点、流动性和成交约束视为模型的一部分。
  3. 稳健性优先 — 关注样本外表现、参数敏感性与替代口径。
  4. 保留失败 — 负结果同样能界定方法的适用边界。
