After making its debut here a week ago at number three, GCM Resources (LSE:GCM) now tops this list of most-bought stocks in ISAs on the ii platform.
Having surged by almost six times the previous week, the Bangladesh-focused mining company peaked at 21.5p last Monday before ending the week down almost 18%. That’s not surprising given the rapid rise in the share price. And GCM’s finance director Keith Fulton appeared to be one of the profit takers, offloading 144,368 shares at 17.255p each to pocket nearly £25,000.
NVIDIA Corp (NASDAQ:NVDA) received a results day boost following a multi-month absence from the top 10, re-entering the list at number five. Quarterly earnings and guidance both exceeded Wall Street’s expectations, prompting a jump in the share price to $230, towards the top of its four-month trading range.
Ithaca Energy Ordinary Share (LSE:ITH) enters this list just behind the American tech giant. The North Sea-focused business, currently worth around £4.5 billion, could gain promotion to the FTSE 100 index this week. Investors have chased the shares higher given its growth pipeline that includes a 20% interest in the Rosebank field, which is subject to regulatory approval for first oil in the first half of 2027. An impressive dividend yield only adds to the attraction.

Ongoing hostilities in the Middle East pushed up the price of oil during the second half of last week, having earlier been laid low by optimism around a solution to the Iran war. It’s why BP (LSE:BP.) shares attracted attention, sending the oil major into this list for the first time since the beginning of August.
Another yo-yo stock, Glencore (LSE:GLEN), is back among the most bought, in at number four from 12 the week before. Shares have been stellar performers for well over a year now but fell sharply on Thursday. However, that was just to factor in the latest dividend plus a special payout, with shares now trading without the right to the latest dividends worth around 12.5p in total. Shareholders receive their money on 18 September.
And finally, Tungsten West (LSE:TUN) makes its debut in this list of hottest ISA stocks. The shares are one of the UK stock market’s best performers so far this year with a 360% gain. A couple of years ago they were worth just 2p. Now they’re changing hands for over 50p.
We reported a week ago that the AIM company will receive £71 million of funding support from the UK National Wealth Fund to restart a Devon tungsten and tin mine.
Politicians were clearly very happy with the deal. Business Secretary Jonathan Reynolds called it “a major vote of confidence in our critical minerals sector.”

Chancellor John Healey said: “We are living in a more dangerous world, which is why backing British industry is more important than ever before. That is what this deal does. We are tapping into one of the largest deposits of tungsten in the world, right here in the UK. This investment will supply vital minerals to British defence, energy and aerospace businesses - and keep good, well-paid jobs in the UK.”
The five stocks making way for this week’s new entries are Aviva, Barclays, NatWest, Imperial Brands and Space Exploration.
Top 10 funds and trusts in ISAs
High-yielding renewables trust Greencoat UK Wind (LSE:UKW) has returned to the bestseller list in a week that has otherwise been marked by consistency.
The trust, which comes with a share price dividend yield just shy of 10% and trades on a roughly 17% discount to portfolio net asset value (NAV), moves to sixth place from 11th a week earlier. Exiting the list, and now at 14th, is the Fidelity Index World P Acc (BJS8SJ3) tracker fund.
Otherwise, investors are sticking with their usual favourites. Royal London Short Term Money Mkt Y Acc (B8XYYQ8) continues its spell in first place, while the rest of the top five is populated by tracker funds and the value-minded Artemis Global Income I Acc (B5ZX1M7).
Growth-focused favourites also remain in the list, in the form of Polar Capital Technology Ord (LSE:PCT), the L&G Global Technology Index I Acc (B0CNH16) and Scottish Mortgage Ord (LSE:SMT).
