Top 10 shares in ISAs

Rolls-Royce Holdings (LSE:RR.) is back at the top of this list of most-bought stocks in ISAs on the ii platform, but it’s a dive in the share price that’s triggered buying this time.

Shares in the aeroengine maker fell 14% last week, taking losses since August’s record high to 27% and their lowest in over five months. Rolls has already been dealing with geopolitical uncertainty and the impact of high jet fuel prices on air fares and, therefore, engine flying hours which can impact profitability.

However, there’s been a negative read across from French peer Safran SA (EURONEXT:SAF)’s third-quarter results. Although sales were broadly in line with consensus expectations, investors were disappointed at the lack of any upgrade to full-year forecasts, especially after peers GE Aerospace (NYSE:GE) and RTX Corp (NYSE:RTX) upgraded earlier in the week. While analysts at Morgan Stanley believe “the market is already pricing in a degree of uncertainty” for Safran, they expect shares “to remain range-bound pending greater clarity on the macroeconomic outlook”.

After slipping to 11th place the week before, Barclays (LSE:BARC) has returned in second place this time after its shares fell to prices not seen since early April. At one point on Friday, losses since the July peak reached 25%. We’ve seen some analysts downgrade forecasts, but some do believe the shares are cheap. Bargain hunters clearly believe that last week’s uninspiring third-quarter results were just a blip.

Lloyds Banking Group (LSE:LLOY) is also back in the top 10, up from 13th last week. The high street bank prepares to publish its own quarterly numbers on Thursday, the day before NatWest Group (LSE:NWG). Both stocks have also slumped to multi-month lows in recent weeks.

International Consolidated Airlines Group SA (LSE:IAG) hasn’t appeared here since March but makes it in at number eight as investors picked up stock at a five-month low. Higher fuel prices triggered by the ongoing conflict in the Middle East have hurt sentiment. So has a decision by Goldman Sachs to trim its price target for IAG by 20p to 500p.

Elsewhere, Aberdeen Group (LSE:ABDN) attracted buying following a dip in response to quarterly results. And a sharp sell-off at Volex (LSE:VLX) means a debut here for the company that makes critical power and data transmission products.

Volex shares slumped on hearing that half-year organic revenue would grow by “at least” 21% year on year, slower than the 28% reported for the first four months of the year, as data-centre programmes that ramped up in the year before annualise.

It says revenue for the six months ended 30 September is expected to be about 7% higher than in the second half of the year ended 31 March 2026. Second-half revenue for the current financial year are expected to be “broadly similar to the first half”. Despite that, analysts at Berenberg raised their price target for Volex to 750p from 700p. Half-year results are due on 12 November.

The five stocks making way for this week’s newbies are IQE, Micron Technology, Taylor Wimpey, Nebius and Aviva.

Top 10 funds and trusts in ISAs

The outperforming, value-minded Artemis Global Income fund is absent from our weekly bestseller list for the first time this year.

The fund, which knocked the Royal London Short Term Money Mkt Y Acc (B8XYYQ8) fund from the top spot for a spell in early 2026 and has returned around 17% so far this year, slips to 13th place.

The fund has benefited in part from its heavy exposure to financials, and to emerging markets, in the last couple of years, although it has at times looked like a momentum portfolio amid such strong returns.

Elsewhere, we see some of the usual funds trading places.

The L&G Global Technology Index I Acc (B0CNH16) returns to the table, rejoining fellow sector fund Polar Capital Technology Ord (LSE:PCT) and the growth-minded Scottish Mortgage Ord (LSE:SMT).

City of London Ord (LSE:CTY), the UK income trust that has built a fanbase around its long record of increasing dividends, moves back into the list, while the Fidelity Index World fund slips to 11th place.

We often talk about the list being fairly consistent, and that remains the case.

The Royal London Short Term Money Market fund continues to hog the top spot, while a handful of broad tracker funds also sit in the table.

We also see a couple of high-yielding trusts in the list, in the form of Greencoat UK Wind (LSE:UKW) and Henderson Far East Income Ord (LSE:HFEL).
