Some of the best-known computer-powered hedge funds have struggled to adjust to the chaotic markets rocked by the coronavirus, with Renaissance Technologies, Two Sigma and DE Shaw seeing some of their biggest funds hurt this month.
一些最知名的计算机驱动型对冲基金近来一直难以做出调整，以适应被新冠疫情扰乱的市场，文艺复兴科技(Renaissance Technologies)、Two Sigma和萧氏企业(DE Shaw)旗下一些大型基金本月损失惨遭。
So-called quantitative funds rely on high-powered computers, vast data sets and algorithms to systematically exploit patterns in securities prices. Their success has spawned a multitude of copycats and led many traditional investment groups to try to emulate their techniques. DE Shaw, Two Sigma, and Renaissance — considered the gold standard of quant funds — now manage close to $200bn combined.
所谓的量化基金就是依靠高性能计算机、庞大的数据集和算法系统地在证券价格中利用模型谋利。它们的成功催生了大量的模仿者，并使得许多传统投资公司尝试效仿它们的技术。被视为量化基金黄金标准的萧氏企业、Two Sigma和文艺复兴科技，目前总计管理着近2000亿美元的资产。
But the ferocity of the recent market turmoil has inflicted some painful losses, forcing many quants to ratchet back their positions. One big investor in hedge funds described the numbers from his quant portfolio as a “disaster”, while some say the setbacks resemble a “ quant quake” — a reference to a brief but traumatic period for the industry in August 2007.
但近期市场的剧烈波动造成了惨重损失，迫使多家量化基金削减头寸。一位对冲基金大型投资者将其量化投资组合的业绩数字形容为一场“灾难”，而一些投资者表示，这些损失类似于一场“量化地震”，上次地震是在2007年8月，导致了该行业一段短暂但痛苦的时期。
