Key Takeaways
  • • AlphaQuest, a $2 billion quantitative hedge fund founded by Nigol Koulajian in 2001, is shutting down after a three-year consecutive losing streak, returning all capital to investors.
  • • The fund has declined approximately 30% since October 2022, marking its worst performance period in its 25-year history, with a 15.2% loss last year and an 11.4% decline through August of the current year.
  • • AlphaQuest rebranded from Quest Partners to AlphaQuest in January to emphasize its alpha-driven investing approach, but the name change failed to reverse persistent underperformance in quantitative markets.
  • • The closure reflects broader challenges facing quantitative hedge funds, particularly in market environments where traditional quant strategies have struggled to generate consistent returns.
Summary
AlphaQuest, a roughly $2 billion quantitative hedge fund led by founder and Chief Investment Officer Nigol Koulajian, is closing operations after enduring its worst-ever losing streak spanning three consecutive years. The fund, which had maintained a 25-year operational history since its founding in 2001, will return all remaining capital to investors, according to Bloomberg reporting.

The fund's performance deterioration has been severe and sustained. AlphaQuest has declined approximately 30% cumulatively since losses began mounting in October 2022. More recent figures show a 15.2% loss in the prior full year and an 11.4% decline through August, representing the fund's worst performance since inception. This extended underperformance stands in stark contrast to the firm's historical track record, which had featured over two decades of double-digit annual returns before the losses began.

The timing of the closure is particularly notable given that AlphaQuest rebranded from its former name, Quest Partners, in January specifically to emphasize its "alpha-driven approach to investing." The rebranding was positioned as a reflection of the firm's money-making prowess, yet the strategy failed to reverse the fund's deteriorating performance trajectory. The closure underscores the vulnerability of even long-established quantitative strategies to sustained market headwinds and changing market dynamics.

Koulajian's decision to shutter the fund reflects broader industrywide challenges facing quantitative hedge funds. The quant sector has experienced material headwinds in recent years, with competitive pressures, technological disruption, and shifting market regimes creating a more challenging investment environment for systematic strategies that historically delivered consistent alpha generation.
