股指期货贴水缩窄 量化基金迎契机

2017-09-22 07:57:13   中国经济网

随着技术进步,量化投资逐渐与基本面投资并驾齐驱,成为当前主流的投资分析方法之一。在过去一年,由于中小创表现不佳,习惯于配置中小创的大多数量化策略没能获得较好收益,不少产品甚至出现较大回撤或亏损。

不过,随着市场风格转变,情况已经得到扭转。数据显示,近期量化基金业绩开始回暖。业内人士指出,随着股指期货的基差情况改善,以及股指期货逐渐松绑,量化策略迎来更好的市场环境。

量化策略回暖

东方财富choice数据显示,截至9月21日纳入统计的496只量化基金中,最近3个月的中位数收益率已经超过7%。相比之下,最近6个月的中位数收益率仅有3.34%。总体而言,量化基金收益率已经回暖。

嘉实基金股票投资alpha策略组组长刘斌表示,今年量化策略整体alpha水平良好,但各产品表现有较显著的分化,偏向基本面及低估值类的量化策略表现相对理想,而偏向小市值风格的量化策略则出现了较明显的回撤。

“与2015年股指期货受限之前相比,量化对冲策略效果不佳,主要源于股指期货深度贴水。股指期货的深度贴水导致量化对冲策略需要付出极高的对冲成本,从而明显侵蚀了策略收益。相信随着股指期货市场的逐渐恢复,无论是股指期货流动性还是基差情况均会所有改善,量化对冲策略也将逐渐恢复正常运作,为投资者带来更好地风险调整后收益。”刘斌表示。

泰达宏利金融工程部总经理刘欣表示,今年量化对冲策略整体都在好转,潜在收益空间随着期货贴水减弱而增加。他说:“我们看重剔除所有风格因子之后的纯alpha回报,因此更稳定。”

擅长量化投资的私募人士徐东波告诉中国证券报记者,其所在团队运用强趋势策略取得了不俗战绩。该策略主要从大盘指数规律、板块指数规律、个股走势规律、基本面消息面宏观面四个维度进行定量和定性分析,形成概率的叠加共振,从而锁定龙头板块、龙头个股。

“运用强趋势策略,我们在2014年成功捕捉到军工板块中的抚顺特钢,券商板块中的兴业证券、中信证券;在2015年成功捕捉到铁路基建板块中的南车北车;2016年成功捕捉到水泥板块中的青松建化;最近半年主要在钢铁、有色、造纸、保险等板块集中操作。”徐东波说。

对冲条件改善

股指期货是量化投资中的重要对冲工具。业内人士指出,如果市场处于贴水状态,将损失贴水部分的基差,多的时候每个月会损失1%以上的收益。反之,升水时则可获得基差部分的额外利润。当前,股指期货贴水缩小,甚至转为升水,对冲条件逐渐改善。
