Although hedge funds have enjoyed unrivalled dominance after years of stellar returns, a combination of low interest rates, sustained economic growth and diminished arbitrage opportunities now threaten them. Distinguishing between funds - an onerous task with notoriously opaque investment strategies - has become paramount in the search for optimal returns.

The innovative Omega ratio is calculated for South African hedge funds and compared with both Sharpe and Sortino ratios. Omega emerges as the superior measure.
