Unique concept and strategy without the costs associated with setting up covered warrants


Why invest in Dejima?

The Japan Synthetic Warrant Fund

The Japan Synthetic Warrant Fund (JSW) was launched in October 2005 and is a synthetic warrant fund investing in Japan. The objective of the Fund is to seek geared exposure to the Japanese equity market. This is accomplished via a combination of buying asset swapped convertible bonds (CB) and purchasing both listed and OTC warrants in companies that are quoted on the Japanese Stock Exchanges.

Unique concept and strategy without the costs associated with setting up covered warrants
The asset swap of a CB creates an option to repurchase the CB at an agreed level.  The structure of the asset swapped options are made up of two components, a synthetic long call on the equity gained through exposure to a convertible bond and a synthetic short of the Japanese Bond market as the Fund sells the fixed income value of the convertible bond under a floating rate repurchase agreement at a fixed LIBOR spread.


Trevor Sliwerski

Partner and Fund Manager – is a founding partner of Dejima and has been involved with the Japanese markets for more than 35 years and was among the pioneers of the Japanese warrant market. In that time he has held senior and significant trading roles in London for Nomura Securities, Robert Fleming, Baring Securities and Investec Bank.

Trevor’s Japanese market career started at Nomura in London and after approximately 2 years Trevor left to join Robert Fleming to act as number two on the convertible trading desk to John Galvanoni. When Japanese warrants were first issued he was responsible for the setting up of their trading desk at Flemings for which he became the director. After working for Robert Fleming for a period of 5 years he left to join Baring Securities with the responsibility of entering them into the market making arena. This was done very successfully and Barings became one of the major players in the market, which led to Trevor becoming a director, and at times being responsible for over 50% of the firm’s profits.

Trevor switched from a trading role to an advisory position at Investec Bank where he originally launched Dejima in the face of the Asian Market crisis. Trevor envisaged, designed and launched the synthetic warrant strategy first with The Dejima Fund Limited in 1998 and moved Dejima to MSG & Partners Limited (MSG, the predecessor to Stratton Street Capital LLP (SSC), which was founded in August 2000 and received its license from the FSA in March 2001. MSG was formed to act as the Advisor to Dejima, which the company took responsibility for in May 2001. The Japan Synthetic Warrant Fund was launched in November 2005 as a weekly dealing sister fund to monthly dealing The Dejima Fund Limited which has since been closed.  Trevor continues to manage the Japan Synthetic Warrant Fund.
