CapeView Capital and Henderson Global Investors have decided to wager against G4S this year. Both firms have set up short positions in the troubled security firm’s shares.

The two London hedge funds’ strategy is undoubtedly justified by the turbulence endured by the company in the last few years since it failed to provide adequate security standards for the 2012 London Olympics.

When setting up short positions in a company’s shares, firms are loaning these out for a defined period of time with the intention of buying them back later, at a lower price.

The two firms join another hedge fund giant, Ako Capital, which has been shorting the security firm’s shares for more than two years.

The majority of the City’s biggest hedge funds, however, has taken the opposite course and closed out their short positions in the company during the last year.
