一、股票期权成交量
港股期权今日成交总数为320430张,其中腾讯个股期权成交量最大,达4.2万张; 阿里巴巴期权成交量居于第二,成交 4万张;美团成交2.2万张; 小米集团居第四,期权成交1.9张。

二、异动观察
百度业绩将出炉,半日升0.6%

百度认沽合计 3,453 张 vs 认购 2,380 张,认沽/认购 ≈ 1.45,整体偏防守。
但单一最大成交是 105 认购(1,976 张),即有资金押业绩后上破约 +4%,这是列表里唯一的明确向上单。
最值得注意的是 8/21 到期的 89 / 90 认沽,合计 1,852 张。3 天后到期、离现价 11%–12%,这种合约只有业绩后向下跳空才有价值——典型的低成本事件尾部对冲。
同样今日公布业绩的小米半日则跌1.7%

全部七个合约的行使价都挤在 25.00–26.00,现价 25.44 正好落在中间。认沽 6,593 张、认购 4,423 张(P/C ≈ 1.49),同一批行使价上认购认沽同时放量,这是跨式/宽跨式押波动率的形态,而非单边。
26.00 是明确的多空分水岭:正股全日最高刚好 26.00,成交量第一的认沽行使价也是 26.00,第二位则是 26.00 认购。
成交量榜首的 26 认沽已经是价内期权(现价 25.44),买入价内 put 的成本高、Delta 大,更像实盘持仓在做业绩前的直接保护。
