Aviva Investors has hired eight fund managers from Standard Life Aberdeen's (SLA) equity team for its new Edinburgh office.
The hires come after Aviva recruited former Standard Life Investments equities head David Cumming at the start of this year as chief investment officer.
The hires include Mikhail Zverev, who has been appointed as head of global equities and Alistair Way, who has been named head of global emerging market (GEM) equities.
All eight held similar roles at SLA and were part of the Standard Life Investments equity team prior the firm's merger with Aberdeen Asset Management last year.
Aviva has also hired Stephanie Niven, who joins from Tesco Pension Investment and will be based in London.
Commenting on the hires, Cumming said: 'We are delighted to attract such high-calibre, experienced individuals with strong performance track records to Aviva Investors, and look forward to them joining the team in the coming months.
'These appointments, along with additional hires we plan to make this year, will complete the creation of strong, integrated teams in the key areas of Global, Emerging Markets, Europe, US and UK Equities.'
Aviva's new Edinburgh office opens this month and has the the capacity to house 60 staff.
The appointments will intensify the rivalry between the fund giants, with Aviva headed by Gars architect Euan Munro (pictured) since his defection from Standard Life Investments in 2013.
'Investing in our equities capabilities is a strategic priority for our business', Munro said.
'These hires will enhance our ability to offer compelling equity propositions for wholesale and institutional investors, as well as strengthening idea generation for our broader range of investment solutions.'
The news comes after SLA restructured its UK equity team earlier this year. The firm indicated the departures were a natural consequence of last year's merger.
'Inevitably when you integrate two investment teams there will be some departures. Following the merger of Aberdeen Asset Management and Standard Life, we have created one of the largest and best-resourced equities teams in the industry,' a spokesperson for SLA said.
'We now have over 150 equity investment professionals on the ground around the world. That scale is important because our approach relies on fundamental research, which we think is best carried out by well-resourced teams which are close to the markets in which they are investing.
'We're grateful for their hard work over the years and are pleased they have found new roles in Edinburgh.'
