It may only be a lesser-known firm managing $400 million for a clutch of strategies for Nordic clients but Seilern Investment Management has something to shout about. A decent performer even before the latest rally in large-cap growth and quality stocks, it is now shooting the lights out.

Over the three years to the start of 2016, Seilern's Stryx World Growth fund returned a cumulative 55.2% in dollar terms, against 31.8% from the MSCI World index. This takes it to 99.2%, against 52.8%, since inception in 2006. Following an indifferent start to the year, the fund has outperformed its peers over the first quarter, according to FE Analytics.
