The US-based asset management giant will be providing research allocation data for Tavistock Wealth's new range of investment portfolios.

The wealth management business of London-listed Tavistock Investments has collaborated with BlackRock to create a new portfolio range called Tavistock Profiles.

The range will combine Tavistock's existing Acumen Portfolios, which comprise eight funds of passive investments including exchange-traded funds, with a range of actively managed BlackRock funds. The Acumen portfolios were built using BlackRock's ETF provider, iShares.

Tavistock Profiles will levy a discretionary fund manager fee of 0.125 per cent plus VAT. Tavistock portfolio strategists will use research data developed by BlackRock to target specific volatility ranges that match investor risk ratings as identified by Tavistock's attitude to risk questionnaire.

“Blending ETF-based portfolios with active strategies can be a cost-effective and flexible way to invest, and we continue to see strong demand for this type of investment. We are pleased to be providing the research data that will support Tavistock's new proposition,” said Michael Gruener, co-head of EMEA Sales for iShares at BlackRock.

“This is a huge step for Tavistock towards becoming a key influence in the UK financial services sector and we very much look forward to working with BlackRock,” added Tavistock's chief executive, Brian Raven.

In February 2015, Tavistock Investments acquired Standard Financial Group, creating a combined firm with around £3 billion ($4.5 billion) in assets under advice. It has since announced the purchases of Cornerstone Asset Holdings and Duchy Independent Financial Advisers.
