SoftBank shares dive after Nvidia sale puts AI valuations in spotlight – business live

8.42am GMT UK bond yields rise amid 'leadership challenge fears' UK government borrowing costs are rising, a little, this morning as bond traders ponder the latest political turmoil in Westminster. The cost of borrowing for a decade, and for 30 years, has risen, following reports that prime minister Keir Starmer’s allies fear he could face a leadership challenge in the wake of this month’s budget. However, it’s not a major selloff, and borrowing costs remain lower than in the summer. With bond prices falling, the yield (or interest rate) on 10-year UK gilts has risen by 3.8 basis points (0.038 percentage points) to 4.42%. That wipes out around half of yesterday’s fall in yields, when expectations of a UK interest rate cut in December pushed up bond prices. The yield on 30-year bonds has risen by almost four basis points, to 5.2% – having fallen by over 7bps yesterday. These long-term borrowing costs remain lower than the 27-year high of 5.7% hit in early September. The PM’’s allies suggest the bond markets would react badly to a change of leader, as investors would have less trust that the UK government was committed to its fiscal rules and to controlling borrowing. Starmer’s most senior political aides warned that any attempt to oust the prime minister over tanking poll ratings would be a “reckless” and “dangerous” move that could destabilise the markets, international relationships and the Labour party, our political editor Pippa Crerar reported last night.

Royal Mail reported a 1.5% increase in revenue to £3.98bn for the 26 week period to 28 September, but said its growth rate would have been 3% if the exceptional period of UK general election mail last year was excluded. The business also saw a strong increase in the number of parcels delivered over the period, up 5% year-on-year to 661m. Letter volumes were down 10% year-on-year, stripping out the general election bump in 2024. Martin Seidenberg, group chief executive of International Distribution Services (IDS), the owner of Royal Mail, says: “We never underestimate the important role we play at Christmas and we are hiring more people, opening temporary parcel sorting centres and putting more vans on the road to deliver for our customers again this year.” However, the company also pointed to rising costs and macroeconomic pressures, including a £120m increase in employer National Insurance contributions (NICS), as well as increased wage costs at its UK business, a result of chancellor Rachel Reeves’s budget last year. In September, IDS acquired a 49% stake in Collect+, which offers access to almost 8,000 pickup points which will be rebranded as Royal Mail. On Wednesday, Royal Mail said it plans to almost double its overall number of collection points to 45,000 locations by 2030, including shops, lockers and parcel postboxes. In September, Royal Mail reported its first annual profit for three years in its maiden results since its £3.6bn takeover by the Czech billionaire Daniel Křetínský. The company said that it will take “many months” to roll out a new system to enable it to slash second-class deliveries, after postal regulator Ofcom gave permission in July to end second-class post on Saturdays and reduce the service to alternating weekdays from Monday to Friday. So far the changes have been limited to a pilot running across 35 delivery offices, with a further roll out planned for next year. 8.21am GMT FTSE 100 hits new record, putting 10,000 point mark in sight Fans of large, round numbers are getting excited as Britain’s stock market hits a new record high at the start of trading. The FTSE 100, which closed at a new peak last night, gained 28 points or almost 0.3%, in early trading to 9,928 points. Energy company SSE are the top riser on the FTSE 100 this morning, up 11%, after announcing a £33bn five-year investment plan which it says will deliver attractive growth and returns. Tabletop gaming company Games Workshop are up 4%, followed by luxury goods maker Burberry (+2.7%). This morning’s rally takes the FTSE 100 closer to the 10,000-point mark for the first time ever, which would cap a super year for the index. Why has the FTSE 100 done well this year? Dan Coatsworth, head of markets at AJ Bell, explains: “Investors have faced considerable uncertainty this year and many have looked away from the US for opportunities. They’ve focused on cheaper areas of the market, of which the UK is one. We’ve seen increased interest from foreign investors looking to diversify their holdings and the FTSE 100 has also shone during the more tumultuous periods thanks to its plethora of defensive-style companies. “When everything looks gloomy or chaotic, such as in the depths of the Liberation Day fallout earlier this year, investors often seek solace in companies whose goods and services should be in demand no matter what’s happening in the world. For example, we all need to pay insurance or water bills, or nicotine addicts will still buy cigarettes or vapes, and the FTSE 100 has plenty of these companies on offer. “Other tailwinds for the FTSE 100 this year include the sharp rise in gold which has benefited the likes of Fresnillo and Endeavour Mining. A push for more governments to spend on defence has also improved the earnings prospects for contractors such as Babcock, another sector well-represented on the UK stock market. “Lots of people have criticised the UK for being an old economy market, full of boring companies in the banking and natural resources sector. Yes, it lacks the excitement of go-go-growth stocks omnipresent in the US, but boring can also be beautiful when it comes to investing. “The UK is a rich hunting ground for dividends, and it is also full of companies that have slow but steady growth and which are underappreciated engines for wealth creation.” Updated at 8.57am GMT 7.59am GMT Japan’s finance chief issues warning over weakening yen Japan’s government is growing anxious about its weakening currency. The yen, which has been generally weakening since the start of October, is approaching the significant level of ¥155 to the dollar, a point where Toyko has intervened in the markets before Japan’s finance minister Satsuki Katayama told the country’s parliament today that the government was watching the sutation closely, saying: “We’re seeing one-sided, rapid currency moves of late. The government is watching for any excessive and disorderly moves with a high sense of urgency.” Katayama also warned that the negative aspects of the weak yen are becoming clearer. The yen’s weakness may be a sign tht the “yen carry trade” is growing in popularity, as risk returns to the markets. This is the situation where investors borrow yen, and use it to buy other, higher-yielding currencies such as the US dollar. Hopes that the US government will reopen soon have spurred risk-on moves, such as the yen carry trade, explains Stephen Innes, managing partner at SPI Asset Management: The reopening of the U.S. government has been a bittersweet elixir for the greenback. On one hand, risk is back on — stocks have caught a second wind, buybacks are flowing, and high-beta FX like AUD are catching the same tailwinds that power stocks. On the other hand, the same optimism that revives equity appetite also reawakens the yen’s old nemesis: carry. When risk levels rise, the mechanical gears of the USD/JPY carry trade start spinning again — cheap yen funding chasing higher U.S. dollar returns, pushing the pair higher almost reflexively. 7.39am GMT Taylor Wimpey blames budget uncertainty for sales slowdown UK housebuilder Taylor Wimpey has warned that sales growth has slowed in the usually busy autumn season. Taylor Wimpey told the City this morning that it was seeing “softer market conditions in the second half of the year”, which it blamed on current uncertainty in the housing market ahead of the November Budget. This slowdown has pulled down Taylor Wimpey’s net private sales rate to 0.63 per outlet per week since June 30, down from 0.71 a year earlier. Jennie Daly, chief executive of Taylor Wimpey. says: “We have delivered a resilient performance thanks to the hard work of our teams on the ground. Market conditions remain challenging, impacted by uncertainty ahead of the upcoming UK Budget and continued affordability pressures. We welcome the Government’s planning reforms, and we hope to see continued momentum to enable the supply of much needed new homes across the UK as focus moves to the implementation phase. However, the Government’s housing ambitions, and the significant economic and social benefits of increased housing supply can only be unlocked by effective demand, particularly for affordability constrained first time buyers. 7.36am GMT The debate over tech stock valuations has intensified, reports Tony Sycamore, market analyst at IG, following the sharp decline in CoreWeave’s share price yesterday. CoreWeave, the Nvidia-backed cloud computing and AI infrastructure provider, plummeted 16.31% to $88.39, driven by disappointing Q3 guidance escalating debt concerns, market rotation away from growth stocks, and supply chain challenges within Nvidia’s ecosystem. It was joined by Nvidia, which slid 2.96% to $193.16, reflecting broader tech weakness ahead of its November 19. Elsewhere, AMD dropped 2.65% to $237.52 and Oracle fell 1.94% to $236.15, significantly below its September peak of $345.72, a decline of about 33%. Updated at 7.44am GMT 7.24am GMT Introduction: SoftBank shares slide after Nvidia stake sale Good morning, and welcome to our rolling coverage of business, the financial markets and the world economy. Shares in Japanese tech investor SoftBank have taken a knock, after it revealed it has sold its stake in chipmaker Nvidia. SoftBank surprised investors yesterday by revealing it sold its shares in Nvidia last month, raising $5.8bn, to fund its other investments in artificial intelligence pioneers, such as ChatGPT parent OpenAI. And the market verdict today has been decisive. SoftBank’s shares touched a one-month low when trading opened in Tokyo - down as much as 10% at one stage – before closing down 3.5%. Although SoftBank insisted there wasn’t a “specific” reason to sell its Nvidia shares in October, the move has raised more questions about whether the sky-high valuations given to companies in the AI sector are solid. It also highlights the growing funding demands SoftBank faces to bankroll its bet on OpenAI and other investments. Shares in Nvidia, whose high-speed chips are used to power AI data centres, fell 3% yesterday, amid a wider drop in tech shares. Related: SoftBank sells stake in Nvidia for $5.8bn as it doubles down on OpenAI bets Analysts have suggested SoftBank’s move shouldn’t cause alarm, though, as it isn’t giving up on AI. Ipek Ozkardeskaya, senior analyst at Swissquote, explains: It appears SoftBank is looking to boost its bets further down the AI chain — toward companies that actually use AI, like OpenAI and ABB Robotics. For those unhappy with the circularity of current AI deals, this is good news…. Meta, for instance, signed a deal with Dutch cloud provider Nebius, which predicted rapid growth next year – and when I say rapid, it’s rapid: their sales soared by more than 300% last quarter. Their share price? It tanked 7% yesterday, along with CoreWeave, which fell 16%.
