Neptune has shut Robin Geffen's Global Long/Short fund after just two years after co-manager Ted Alexander exited the firm.
Alexander (pictured), who managed the fund with chief executive Geffen and was responsible for implementing many of the short ideas, left in September in order to return to academic study.
Neptune then began winding down the fund, before formally closing it on 16 December.
The fund ran for less than three years having launched in October 2011. It invested in ten different sectors across the globe, holding large liquid stocks.
However, despite having Geffen at the helm, the fund failed to attract much interest, holding just £5m at its peak.
