The Partnership is a long-short investment fund with a long bias. Under normal market conditions, the Partnership expect to have at least 90% of its assets invested in liquid large cap US publicly listed securities. The Partnership will generally use computer-aided, quantitative analysis to select stocks that the Manager believes may have the potential to provide a higher total return than that of the broad US equity markets. Short positions will generally be capped at 30% of assets, at the time of investment.
