期权观察:认购期权增持

2017-09-13 10:07:39   中国经济网

周二A股冲高回落尾盘跳水,上证综指、深成指均创下反弹新高。板块方面,新能源汽车、白酒、充电桩、证券等涨幅居前;高送转、次新、军工等板块回调。期指方面,主力合约均收红,IH主力走势弱于现货指数,但仍维持升水状态。期权方面,标的资产上证50ETF上涨0.59 %收于2.746,隐含波动率基本持平,目前上海证券交易所公布的iVX指数为15.17%。

期权持仓量增加成交量减小。当日全市场合计成交70.60万张,较上一交易日减小4.27万张。其中,认购期权合约总成交42.94万张,较前一交易日减少1.36万张,认沽合约总成交28.12万张,较前一交易日减小2.80万张。日成交量PCR为0.65,较前一交易日0.7有所减小。持仓方面,截至周二收盘,期权总持仓197.83万张,较周一持仓量增加3.51万张。其中,认购合约持仓102.83万张,较前一交易日增加2.57万张,认沽合约持仓99.72万张,增加1.0万张,持仓量PCR值由0.98减小为0.97。

图为9月平值期权隐含波动率走势

从当月期权合约成交持仓变动看,9月合约成交量较上一交易日减小5.48万张,持仓量增加1.49万张,其中认购期权增持1.28万张,认沽期权仅增持0.21万张。从各执行价的成交持仓数据看,认购期权执行价为2.75的合约增持最大,为0.6万手;认沽期权执行价为2.70的合约增持0.25万手。整体来看,市场偏空振荡情况下上证50指数受青睐,认购增持更多。

从9月平值期权隐含波动率及历史波动率对比看,最近10个交易日50指数振荡回调,历史波动率回落至12.2%。隐含波动率分化,认购期权明显强于认沽期权,两者差值达到3.5%,为近期新高。

随着尾盘热点板块跳水,市场情绪有所回落,近期上证50指数有望接力上行。投资者可布局牛市看涨价差组合,激进者可做多认购期权。
