Henderson and Janus form a two-faced asset manager
Shares in Henderson Global Investors shot up more than 18 per cent to 274p in early trading after it unveiled plans to merge with Janus Capital, the asset manager bond king Bill Gross famously ditched Pimco for.
In a statement today Janus said it was merging with Henderson Global Investors to create a giant asset manager with $320bn (£247bn) of assets under management and a combined market capitalisation of $6bn.
The merger of equals will leave Henderson and Janus shareholders with 57 per cent and 43 per cent respectively of the creatively-titled Janus Henderson Global Investors – although the deal isn't expected to be sealed until the second quarter of next year.
