A股低波动或成未来常态

2017-09-27 08:17:53   

单日振幅0.44%,上证综指昨日在不到15个点的空间内完成了全天窄幅震荡走势。上证资讯统计显示,截至昨日收盘,沪综指已经连续21个交易日单日振幅不超过1%,而上一次出现超过连续20个交易日低振幅的情形还要追溯到25年前。市场人士认为,今年以来沪综指出现波动率明显下降的现象,正是A股市场逐渐走向成熟的表现。

年内多次出现低振幅情形

今年以来,沪综指在3000点至3400点的空间内震荡,总体实现小幅上扬。市场非理性波动明显减少,指数波动率出现显著回落。

上证资讯统计显示,除了目前的情况外,沪综指历史上仅有15次出现连续10个交易日以上(含10个交易日)单日振幅均不超过1%的窄幅震荡行情,其中有7次发生在市场设立初期,即1991年至1992年期间。由于当时市场整体规模较小且参与人数有限,沪综指曾最多连续45个交易日单日振幅不足1%。其余8次均发生在2000年以后,其中半数发生在2000年8月至2001年6月,最大持续时间为10个交易日至13个交易日不等。回看彼时市场走势,沪综指在经历“5·19行情”后,围绕2000点左右窄幅震荡超过一年时间。

有意思的是,另外4次中有3次发生在今年,1次发生在2014年。具体来看,沪综指曾在今年1月18日至2月7日、2月21日至3月10日、6月8日至6月21日三段时间内出现连续单日振幅不超过1%的情况,分别持续10个、14个和10个交易日。

这也意味着,目前沪综指连续21个交易日低振幅的情况极为罕见,上一次出现类似情况还得追溯到1992年2月。值得一提的是,考虑到即将到来的长假因素,沪综指低振幅持续天数有望继续扩大。

这一现象在更长的观察周期上表现得更为明显。9月还有3个交易日,沪综指本月初至今最大振幅仅为1.76%,这一数字刷新了沪综指单月振幅新低。上证资讯统计显示,沪综指从发布至今仅有12次出现单月振幅不足4%的情形,占所有月度数据的比例为3.7%。

低波动后向上概率更大

投资者更关心的是,市场在持续低波动后会何去何从。从历史数据来看,沪综指在经历持续低振幅后,后续出现上涨的概率更大。

典型案例发生在2014年6月末。沪综指在当年6月20日至7月8日期间,曾连续13个交易日单日振幅不足1%,区间最大震荡幅度不超过60点。经过横盘蓄势后,沪综指在当年7月末放量突破,并随后在流动性宽松等多重因素影响下走出一波波澜壮阔的涨势。

据上证资讯统计,自2000年以来,以沪综指结束连续低振幅日为起点,从此后一段时间股指运行情况来看,实现上涨的概率更大。换句话说,沪综指在连续横盘后选择向上突破的可能性更高。
