What Acumen Capital does

Acumen Capital is a privately held South African boutique investment management firm founded in 2001 by Stuart Conway and Mark O'Brien, headquartered in Fourways, Johannesburg. The firm operates a single core product — the Acumen SCI Absolute Income Retail Hedge Fund (originally launched as the AcuityOne hedge fund in September 2009) — which invests primarily in South African Government Bonds and interest rate derivatives including swaps and FRAs. The fund is regulated under CISCA (effective 1 September 2016) and classified by ASISA as a Retail Hedge Fund – South African – Fixed Income. Acumen Capital serves both retail and institutional investors seeking positive returns independent of interest rate direction over a long-term horizon, with a moderate-to-high risk profile.

The firm's investment process is anchored on proprietary analytical tools developed over a 20-year period specifically for the South African interest rate environment. These tools enable rigorous analysis of yield curves on both historical and forward bases across short, medium, and long-term horizons, allowing the portfolio managers to identify pricing anomalies and capitalise on supply/demand inefficiencies. Portfolio construction combines fundamental and technical expertise with comprehensive cash flow analysis. Leadership is concentrated in three directors — Conway (BSc Actuarial, ex-Head of Interest Rate Trading at Absa Bank), O'Brien (ex-Chief Dealer at Absa Capital Markets), and Greg Kamstra (BSc Hons, ex-Merrill Lynch Capital Markets SA, ex-Citibank NA, ex-Peregrine) — collectively bringing over 60 years of investment industry experience. A compliance officer (Chris Oelschig) supports the regulated entity Acumen Capital (Pty) Ltd (FSP No. 14927).

Revenue is generated through a Class 2 fee structure comprising a 1.5% annual management fee and a 20% incentive fee calculated on the fund's NAV. Distribution is direct, with daily subscription and monthly redemption available to investors and no lockup period. Service providers include Apex Fund and Corporate Services SA (administration), RMB/ABSA (prime brokerage), SCI Management Company (CISCA management company), FirstRand Bank (trustee), ECOVIS ARB Auditors (audit), and Edward Nathan Sonnenbergs (legal). The fund has delivered 14.69% annualised returns since inception and won the HedgeNews Africa 2020 award for best 5-year annualised returns in the fixed interest category.
