SecFinex, a European trading platform for stock lending, has appointed an ex-consultant and senior advisor at a financial services consultancy as chief executive to grow the business following its takeover by NYSE Euronext last December.

Peter Fenichel succeeds Allen Postlethwaite, who is a co-founder of the group and was serving as interim chief. Postlethwaite will now move to the role of chief operating officer at SecFinex.
