Cofunds, Fidelity's FundsNetwork and Seven Investment Management, the UK-based mutual funds supermarkets, have agreed to introduce sharing of client portfolios. The three on-line wrap platform groups argue that the unprecedented initiative - planned for the first quarter of 2008 - will allow advisors to see clients' overall portfolios more clearly and to make asset allocation decisions accordingly. The tie-up should permit contract enquiries to be undertaken between 7IM and Cofunds and 7IM and FundsNetwork. There are no plans for Cofunds and FundsNetwork to share data. The move to increase visibility between platforms will lessen the need for platform-to-platform in-specie transfers, which has recently divided the Platform Group of which Cofunds and FundsNetwork are members. In the first part of the collaboration, Cofunds and FundsNetwork are both putting 7IM's discretionary funds on their platforms. 7IM chief executive Tom Sheridan said: "This additional connectivity will provide financial planners and wealth managers with more choice for their clients, adding more credibility to their independent positioning. Not only will a wider range of tax wrappers be available, but also a broader selection of securities and services.
