Top 10 best-selling ISA and SIPP funds in April

Cash funds remained the most popular choice among Fidelity’s Personal Investing ISA and SIPP customers last month, while global funds regained some of their earlier popularity at the expense of UK funds. One of the global funds was a gold fund, which entered the SIPP top 10 as the price of the precious metal reached repeated record highs this year.

The most popular ISA funds in April 

ISA investors rediscovered some of their appetite for American stocks in April, perhaps ‘buying the dips’ after the sharp falls on Wall Street in the wake of Donald Trump’s ‘Liberation day’ tariffs announced on 2 April. Just one US fund had made it into March’s top 10 best-sellers’ list, Fidelity Index US in ninth place, but it climbed to sixth position in April and was joined in ninth place by the UBS S&P 500 Index fund. 

Savers also put more money into global funds, which in practice are heavily invested in American companies. Whereas just three global funds had appeared in the top 10 in March, compared with five in February, four featured in April’s table: Fidelity Index World in an unchanged second position, Fidelity Global Dividend unmoved in fourth place, Legal & General Global Technology Index in eighth position after dropping out of the table in March, and Rathbone Global Opportunities likewise reappearing in 10th place after a month’s absence from the top 10. 

To make way for these arrivals, two UK funds disappeared: Legal & General UK Index Trust (eighth place in March) and Fidelity Special Situations (10th most popular in March). Just one UK fund remained, Fidelity Index UK in an unchanged seventh position. 

The remaining three places were taken up by cash or ‘money market’ funds. The Fidelity Cash Fund was in first place, the Royal London Short Term Money Market Fund in third and the Legal & General Cash Trust in fifth – all unchanged from the previous month. Many investors seem to be seeking safety in cash as Mr Trump’s economic policies trigger volatility on the stock market.
