私募经理被“虐哭” 量化对冲策略失灵逾四成产品亏损

今年A股市场的行情表现一反常态,“一九”特征明显,绝大多数个股跑输大盘。这就使得通过股指期货对冲来控制回撤的量化对冲私募“束手无策”,纳入私募排排网研究中心不完全统计的401只相对价值策略对冲基金产品中,负收益产品多达184只,占比达45.88%,其中甚至包括知名私募的部分产品,也出现了较大亏损。

对冲产品今年大面积亏损

今年以来,A股白马股涨势如虹,除少数龙头股外,绝大多数个股跑输了大盘。在这种极端的情况下市场“一九”行情特征明显。不过从近期来看,由于蓝筹股、周期股的上涨尚未结束,中小创在底部调仓规模还比较小。目前私募的整体仓位在70%左右,但有激进的私募仓位更高甚至满仓操作。值得注意的是,原本希望通过股指期货对冲来控制回撤的量化对冲私募基金却没有想到今年会被“虐哭”。

近期就有私募人士在私募圈表示,上半年手里重仓了一些白酒等消费类个股,收益也不错,但是因为使用了股指期货进行对冲,消费类个股的收益却被全部对冲掉了,使得上半年打了个平手,业绩也就不那么出彩,甚至影响到自己近期发行新产品了。据《每日经济新闻》记者了解,实际上在今年上半年“一九”行情中,甚至还有私募基金经理陷入两面“不讨好”的尴尬境地。

《每日经济新闻》记者注意到,今年以来,以低风险著称的市场中性和套利策略私募产品在今年出现大面积亏损,据私募排排网研究中心不完全统计,今年上半年共有401只成立时间满足6个月,并且有业绩记录的相对价值策略对冲基金产品纳入统计,其中负收益产品多达184只,占比达45.88%,其中多达19只产品今年以来亏损在10%以上。如中金浦成旗下的对冲精英之金御安远七期A今年以来亏损19.29%,宁波阿尔法旗下的阿尔法量化趋势策略3号今年以来收益为亏损13.39%,润泽允能旗下的允能量化对冲今年以来收益为负13.28%。

值得注意的是,知名百亿级私募大岩资本旗下多只相对价值产品亏损居前,其中“千石资本-大岩绝对”今年以来收益为亏损13.21%,此外还有旗下“外贸信托-安进1号”今年以来收益为亏损11.28%。

对此上海证大资产基金经理刘兵告诉《每日经济新闻》记者,今年市场风格较为鲜明,历史有效的因子均出现了一定程度的回撤,甚至有些因子起到了反效果,对冲工具因为基差的问题也较为匮乏。对此首先还是尊重历史回测数据,尊重市场,会继续使用回测表现较好的量化策略,但考虑当前的行情,对个别因子会进一步降低权重。
