Renaissance Technologies, one of the world’s most successful and secretive hedge fund groups, is to wind down a $1bn investment fund after its underwhelming performance failed to attract enough outside investors.

全球最成功且最隐秘的对冲基金集团之一文艺复兴科技(Renaissance Technologies)将关闭旗下一只10亿美元的投资基金，此前该基金平平的业绩未能吸引足够多的外部投资者。

The hedge fund manager, founded by former Pentagon codebreaker and mathematician James Simons, is mostly known for its phenomenally successful flagship fund Medallion, which is now closed to outside investors.

这家对冲基金管理公司由美国前五角大楼密码破译者、数学家詹姆斯缠馉斯(James Simons)创建，最知名的是其极其成功的旗舰基金大奖章(Medallion)，目前不对外部投资者开放。

But Renaissance Technologies has also set up a handful of other funds that remain open to investors, including a so-called “managed futures” fund called Renaissance Institutional Futures Funds that uses algorithms to invest in financial derivatives across the world, taking advantage of market trends.

但文艺复兴科技也建立了少量仍对投资者开放的基金，包括一只名为文艺复兴机构期货基金(RIFF)、所谓的“管理期货”基金(managed futures)，它利用市场趋势运用算法投资于全球金融衍生品。

The fund has about $1bn of assets, and has returned 1.75 per cent this year and 2.86 per cent annualised since its establishment in September 2007, according to a person close to the situation. But that is less than the almost 4 per cent average for managed futures funds and well below the industry’s best-known vehicles.

据一名知情人士称，该基金管理着大约10亿美元的资产，今年的回报率为1.75%，自2007年9月创建以来年化回报率为2.86%。但这不及管理期货基金近4%的平均水平，也远远低于该行业最知名的投资工具。

However, RIFF was ended primarily because many investors preferred the Renaissance Institutional Alpha Funds, which was set up in 2012 and invested in futures and cash equities. Most of the capital in RIFF is now internal Renaissance money, according to a person familiar with the matter, so the decision was made to close the fund altogether.

RIFF关闭的主要原因是很多投资者青睐2012年成立的文艺复兴机构阿尔法基金(RIAF)，该基金投资于期货和现金股票。据一位知情人士称，目前RIFF的多数资金都是文艺复兴内部资金，因此做出了彻底关闭该基金的决定。

“We kept RIFF open for any investors who wanted, or had a mandate, to invest in a futures-only fund. Unfortunately, there are not enough such investors to justify the standalone futures fund,” Renaissance Technologies said in a letter to its investors. A spokesman for the hedge fund manager declined to comment.

文艺复兴科技在一份写给投资者的信中表示：“RIFF曾向所有希望或获得委托要投资于期货基金的投资者开放。不幸的是，投资者数量不足以证明该独立期货基金存在的合理性。”这家对冲基金管理公司的发言人拒绝置评。
