Royal London Short Term Money Mkt Y Acc has given up its place as the weekly ISA bestseller, ending a six-month spell at the top of the table.

The fund, which offers cash-like returns, has fallen to second place, displaced by the US-light Artemis Global Income I Acc, which returned roughly 45% in 2025.

The reshuffle partly reflects the sheer strength of returns from the Artemis fund, which takes the top spot for the first time. But there’s also a chance that the Royal London fund, and cash funds in general, could lose their shine as interest rates fall.

The Bank of England cut the rate to 3.75% in December and returns from cash funds (and cash accounts) have reduced in turn.

Investors could well now look to seemingly safe assets which pay out higher amounts, such as bonds, or even turn to riskier assets.

We’ve noted that Artemis is enjoying a moment in the sun, and another of its strong performers crops up in the list this week.

Artemis SmartGARP European Equity, which uses a proprietary screening tool to identify stock picks, returned roughly 56% last year and has a big allocation to financials, moves into the table in eighth place. The UK offering from the same franchise, Artemis SmartGARP UK Eq I Acc GBP, sits just outside the table in 15th place.

There’s the usual presence of global equity trackers (and one of Vanguard’s LifeStrategy funds) in the list, plus two very different investor favourites in the form of adventurous global growth fund Scottish Mortgage Ord  SMT

 and steady UK income play City of London Ord  CTY.

Elsewhere, it’s interesting to see two investment trusts with very different runs of performance in the top five.

With geopolitical strife back on the agenda, shares in Seraphim Space Investment Trust Ord  SSIT

many of whose holdings have been busy signing defence contracts, have returned almost 9% so far in 2026. That has pushed the shares on to a premium to net asset value (NAV), which at one point reached almost 18% last week but has since moderated to around the 9% mark.

Greencoat UK Wind  UKW

which has been in the wars amid a challenging few years for the renewable energy infrastructure sector, moves up to fourth place. It’s likely that investors still spy a bargain here, given that the shares trade on a roughly 31% discount and come with a dividend yield of more than 10%.

There are plenty of big yields now available in that sector, although this may suggest investors are sceptical about how sustainable they are. NextEnergy Solar Ord  NESF

shares now come with a yield just shy of 17%, for example.
