问题背景 "五一"假期期间境内休市而境外市场仍在交易，投资者面临"无法即时对冲"的风险。期权隐含波动率（VIX）成为衡量假期不确定性的 关键指标。对50ETF期权而言，交易者普遍认为"节前买保护、节后消化"是经验法则，但这种印象缺乏系统量化验证。本研究希望回答 两大问题：一是波动率在"五一"前后具体呈现怎样的时间结构，二是能否据此设计可行的波动率交易策略。探索这些问题不仅能丰富国 内节假日效应文献，还可为期权做市商、对冲基金与量化交易员提供优化 Vega 暴露与 Gamma 管理的实证依据。 表为"五一"前后波动率规律的解释 上表将"五一"前后相对交易日分为五大区段：节前第一阶段（T-5→T-4）、节前第二阶段（T-4→T-2）、节前第三阶段（T-2→T-1）、节 后第一阶段（T+1→T+2）、节后第二阶段（T+3→T+5）。其中，节前阶段先现小幅抬升,从第5日均值19.6升至第4日19.7，标志风险溢 价初显；随后在第3日到第2日，隐含波动率快速回落至18.9，反映卖方平仓与套利流动性入场；最后一个交易日（T-1）跌至全周期最低 18.8，说明做市商通过降价吸纳Gamma敞口，平滑假期前头寸。假期结束后的首 ...
