Blue chips in London enjoyed another strong day on Friday, hitting a fresh peak, with a pick up in new listings adding to the more optimistic mood.

The FTSE 100 index closed up 63.52 points, 0.7%, at 9,491.25, a new closing high, and just shy of a fresh intra-day best level of 9,494.64 hit earlier in the trading day.

The FTSE 250 ended up 150.32 points, 0.7%, at 22,197.62, and the AIM All-Share advanced 7.57 points, 1.0%, at 796.52.

For the week, the FTSE 100 was up 2.2%, the FTSE 250 was 2.4% higher, while the AIM All-Share added 2.1%.

The upbeat mood came despite the ongoing US federal government shutdown and some downbeat domestic economic data.

AJ Bell investment director Russ Mould said: “There is growing expectation that the shutdown in Washington might continue until mid-October.

“How long investors remain relaxed about this state of affairs remains hard to predict, but one worry is that it makes it significantly harder for the Federal Reserve to make informed decisions around interest rates,” he added.

In the UK, speculation of tax hikes ahead of the Autumn budget was blamed for a slowdown in services sector activity in September.

The S&P Global UK services purchasing managers’ business activity index fell to 50.8 points in September from 54.2 in August, and missed the flash reading of 51.9 released late last month.

Tim Moore at S&P Global said: “Many survey respondents suggested that corporate clients had deferred spending decisions until after the Autumn budget, while households were also hesitant about major purchases.”

In better news for the “Square Mile”, consumer staples company Princes Group said it intends to float on the Main Market of the London Stock Exchange.

The Liverpool-based firm reported £2.1 billion in pro forma revenue in 2024, and pro forma adjusted earnings before interest, tax, depreciation and amortisation of £122.3 million.

Its portfolio includes Princes tuna, Branston, Flora, Napolina and own-brand products.

Chief executive Simon Harrison said: “Whilst we are renowned for our iconic Princes tuna, through a combination of organic growth and focused M&A, we have built an international £2 billion food and drink portfolio.”

In addition, Beauty Tech Group made its stock market debut in London.

The Cheshire-based seller of at-home beauty treatment technology, including laser devices and LED face masks through the brands Tria Laser, CurrentSkin and Ziip Beauty, closed at 288p per share, above the 271p initial public offer price in a successful first day’s trading.

Stocks in New York were higher at the time of the London close. The Dow Jones Industrial Average was up 0.8%, the S&P 500 index was 0.4% higher and the Nasdaq Composite 0.2% to the good.

In European equities on Friday, the CAC 40 in Paris closed up 0.2%, while the DAX 40 in Frankfurt fell 0.2%.

Amid the bullish market mood, Bank of America strategists said there is a risk that markets are “under-pricing the risk of weakening growth momentum”, and as well as “potentially over-pricing the support from productivity growth”.

As a result, BofA said it is positioned for macro data to “surprise to the downside relative to lofty expectations”, implying scope for widening risk premia and fading EPS expectations, consistent with “more than 10% downside for the Stoxx 600 and 10% underperformance for European cyclicals versus defensives”.

The pound was quoted higher at 1.3469 dollars at the time of the London equity market close on Friday, compared to 1.3415 dollars on Thursday. The euro stood at 1.1741 dollars, up against 1.1697 dollars. Against the yen, the dollar was trading at 147.43 yen, slightly higher compared to 147.37 yen.

The yield on the US 10-year Treasury was quoted unchanged at 4.11% from Thursday. The yield on the US 30-year Treasury stood at 4.70%, also flat from Thursday.

Broker recommendations drove a number of the leading risers on the FTSE 100.

Bunzl climbed 4.5%, as Goldman Sachs took the international distribution and services group off its “sell” list, moving to “neutral”.

While RBC Capital Markets double upgraded London-based supplier of specialised technical products and services Diploma to “outperform” from “underperform”, sending shares 2.3% higher.

RBC said Diploma’s track record in terms of organic growth, earnings before interest, tax and amortisation margins, cash conversion and, importantly, return on invested capital, “speaks for itself”.

The broker added: “The majority of financial metrics are at the top-end of the sector whilst the diversity of the business provides resilience through the cycle.”

Schroders closed up 3.7% as Citi upgraded to “buy” from “neutral” after recent underperformance that it called “somewhat surprising”.

The broker said the financial services provider has among the highest gearing to strongly-performing equities across its coverage, recent flow momentum appears strong, while it should also be “positively geared” to any improvement/recovery in private markets activity.

Meanwhile, Intertek advanced 2.6% as Bank of America restarted coverage with a “buy” rating.

Banks were a firm feature, with NatWest up 3.8%, Standard Chartered up 1.7%, Barclays up 1.4% and HSBC up 1.7%.

Elsewhere, JD Wetherspoon failed to cheer investors with shares down 5.6%, despite a strong rebound in profits and record sales, as analysts warned that rising wage and energy costs could crimp margins and stall momentum in the new financial year.

Audioboom stormed 18% higher after Sky News said it is working with advisers to explore terms of a potential takeover of the company.

New York City-based Fox Corp and San Antonio, Texas-based iHeartMedia could be potential bidders for the London-based podcast producer of Formula One motor racing’s official podcast, according to media analysts.

Brent oil traded at 64.61 dollars a barrel on Friday, up from 64.42 dollars late on Thursday.
