Money Marketing research, in conjunction with Financial Express, shows that of the 313 top-quartile funds between December 2004 and 2007, 160 produced third or fourth-quartile performance in their respective sectors last year.
Of the underperforming funds, six managed to lose more than 50 per cent of their assets, with JPM New Europe heading the list with a loss of 61.76 per cent.
Other funds which fell flat include Neptune Russia and Greater Russia, which lost 59.2 per cent while the SVM UK opportunities and New Star hidden value funds lost 55.19 and 54.98 per cent respectively.
Bestinvest analyst Tom White says: “There are various factors that investors may tend to overlook in the midst of a bull market. For example, a fund may be aggressively positioned and may get caught by things such as the mid and small-cap struggles.”
Hargreaves Lansdown investment manager Ben Yearsley says: “There were so many funds that made the small or mid-cap call and until 2008 that was the right call to make. It is more of a structural bias by them rather than a case of fund managers chasing the hot spot and getting burned.”
