The deal will see Dalton, which also offers the Melchior range of funds, take over MSK’s fund range including its Ucits-structured Global Equity, a long/short strategy.
MSK’s funds will retain the current branding after the buyout.
As part of the deal senior managers from MSK, which is based in the exclusive St James’s area of London, will join Dalton.
Among those moving are fund manager Makis Kaketsis, who was among the original founders of MSK in October 2009 along with corporate backers.
MSK’s £184m of assets will be added to Dalton’s £1.47bn to create a group with a broader range of expertise and strategies, the groups said in a statement.
The statement said both firms’ senior management had “longstanding professional and personal relationships”.
Dalton is known for being the brainchild of respected investment manager Andrew Dalton, formerly of Mercury Asset Management, who died in April 2011.
Today the firm has offices in London, New York, Hong Kong and Tokyo.
Wence Von Liechtenstein joined the firm last year and became its CEO in August.
“This is an important step forward in the development of Dalton Strategic Partnership. Makis and his team have a very strong investment process, a shared vision and are a close cultural fit,” he said.
“We look forward to welcoming and integrating them into our group.”
