Top 10 shares in ISAs

Despite making regular appearances in this list of most-bought stocks in ISAs on the ii platform, Lloyds Banking Group (LSE:LLOY) hasn’t topped the table since May.

And its three-place rise comes in a week when three other FTSE 100 bank shares also made it into the top 10. The UK bank sector has struggled since peaking during the summer and now trades at multi-month lows. In fact, it was one of the worst-performing sectors in September with an 8% drop.

Share prices have suffered amid concerns about bond yields reaching multi-decade highs, and the impact that could have on consumers. Barclays (LSE:BARC) has also been vulnerable given exposure to the US economy and a softer period of investment banking activity. The lender joins Lloyds, NatWest Group (LSE:NWG) and HSBC Holdings (LSE:HSBA) among the week’s most bought stocks, with investors picking up bargains while also mulling positive commentary from analysts.

NatWest makes a return to the top 10 having been 11th the previous week, Barclays is in at number six from 13th last time, while HSBC creeps into 10th spot.

Analysts at JP Morgan raised their price target for Barclays by 10p to 630p and by the same amount for NatWest to 840p. Lloyds nudges up a penny to 124p. Last month, the broker predicted a boom in corporate lending, with UK banks big beneficiaries given much lower debt levels than before.

NatWest has also received support from RBC Capital Markets, predicting that rising interest rates would have a large positive impact on profits by 2028.

Elsewhere, Tullow Oil (LSE:TLW) debuts in this list at number three. The oil company’s shares lost about half their value following developments in Ghana. A tribunal ruled that a $196.5 million (£148.6 million) corporate income tax assessment under Tullow’s corporate Business Interruption insurance policy is not in breach of its petroleum agreements with the Ghanaian government.

“We continue to expect other E&P players to take an interest in Tullow’s operated portfolio and flagship Jubilee asset, in expectation that merging with a stronger balance sheet could lower the cost of debt and boost investment levels and output,” said broker SP Angel.

Aviva (LSE:AV.) is back in the top 10 as investors picked up shares trading near their lowest in over two months and down almost 10% from their August peak. 

AstraZeneca (LSE:AZN) is also here again after a two-week break. Shares are still not far off a one-year low, but a new clinical collaboration and $2 billion (£1.5 billion) investment will make it the second-largest shareholder of Nasdaq-listed Summit Therapeutics Inc Ordinary Shares (NASDAQ:SMMT).

Analysts at Jefferies were positive, repeating their price target of 17,500p, implying more than 40% upside potential.

The six stocks making way for this week’s newbies are 80 Mile, Standard Life, Raspberry Pi, BP, BT and Strategy.

Top 10 funds and trusts in ISAs

UK equity income stalwart City of London Ord (LSE:CTY) has returned to our weekly bestseller list, alongside a global tracker fund.

City of London, which moves from 11th place to ninth, has continued to enjoy a good spell of performance, with shareholders in the trust slightly ahead of a 14.5% total return for the FTSE 100 over the last 12 months.

The trust recently marked its 60th annual dividend increase, and the shares yield around 4%. They do also trade on a 2% premium to the value of the portfolio assets, meaning investors are slightly paying up for this exposure.

Another name to return to the list is Fidelity Index World P Acc (BJS8SJ3), which joins three other broad tracker funds in the list.

Otherwise, investors continue to stick with some of the same names, from cash fund Royal London Short Term Money Mkt Y Acc (B8XYYQ8) to the hard-running value fund Artemis Global Income I Acc (B5ZX1M7), yield play Greencoat UK Wind (LSE:UKW) and Scottish Mortgage Ord (LSE:SMT), which looks to get top returns targeting future trends.

We also see L&G Global Technology Index I Acc (B0CNH16), which offers concentrated exposure to the US tech majors, in the list. But the actively managed Polar Capital Technology slips out of the table, as does the Vanguard LifeStrategy 100% Equity fund.
