Shares in financial sector buyout firm Resolution were today trading 15% above their offer price in the first successful flotation of more than $100m (€77m) on the London Stock Exchange for 21 weeks, while shares in London-based fund manager Henderson Global Investors also jumped over 10% on speculation that it could be bought by Resolution.

Insurance entrepreneur Clive Cowdery raised £600m (€691m) in funding last week from some of the UK's largest pension funds and hedge funds for today's flotation of Resolution.
