智通财经APP获悉，6月9日，香港交易所宣布更新股票期权主要庄家计划，此次计划将于7月2日(星期四)生效，为期1年至2027年6月30日，包括该日。本次纳入主要庄家计划包括友邦保险(01299)、百度集团(09888)、比亚迪股份(01211)、中国移动(00941)、汇丰控股(00005)、腾讯控股(00700)等22只标的。
根据规则要求，本次计划的申请主体有着明确门槛，合资格申请人须为该股票期权合约过往12个月的现有主要庄家及/或持续报价庄家。履职责任方面，新规对主要庄家的报价服务提出标准化要求：
针对期权买卖盘差价，港交所会根据相关股票的流动量及波幅而为每只股票期权合约划分为水平1(流通量高期权的正常差价)，水平2(流通量低期权的较阔差价)及水平3(波幅较高期权的较阔差价)，若出现任何变动会以电邮预先通知主要庄家。同时为激励庄家履职、提升市场流动性，港交所配套了梯度化交易费用折扣政策。
