The assets of Sloane Robinson, one of London’s oldest hedge fund managers, have fallen five-fold from a peak of $15bn before the financial crisis, after years of gradual decline.

The firm's assets more than halved from $7.2bn to $3bn in the year to June 30, 2012, according to Financial News' recent annual survey of the largest managers in Europe. This was enough to push it out of the top 20 largest managers in Europe.
