Late market roundup: Stocks close higher on new hope for US-Iran peace

The FTSE 100 ended higher on Tuesday, with mining stocks among its best performers, while renewed optimism over a possible peace deal between Iran and the US pushed Brent crude's price closer to the USD80 mark.

The FTSE 100 index closed up 21.68 points, 0.2%, at 10,879.38. The FTSE 250 ended up 234.53 points, 1.0%, at 24,459.30, while the AIM All-Share closed up 5.75 points, 0.8%, at 774.36.

The Cboe UK 100 was up 0.4% at 1,082.02, the Cboe UK 250 was 0.9% higher at 21,229.96, and the Cboe Small Companies was up 0.4% at 18,742.97.

Oil prices headed towards USD80 a barrel after US Treasury Secretary Scott Bessent said a deal could be reached with Tehran by Wednesday on re-opening the Strait of Hormuz to shipping traffic.

Bessent told CNBC that "I think there is a chance we may have a deal today or tomorrow to open the strait" – a key sticking point in ceasefire talks with Iran.

"So you know, I'd expect the energy prices to settle back down, which, as I said, will be good for the entire world," he said.

In response, Brent oil for October delivery traded lower at USD80.60 a barrel on Tuesday afternoon, from USD83.92 late Monday. The falls dragged BP and Shell lower, by 4.9% and 2.5% respectively.

BP also unveiled better-than-expected second quarter results with underlying replacement profit before interest and tax soaring to USD10.31 billion in the quarter ended June 30 from USD5.25 billion the year prior, ahead of the company-compiled consensus of USD9.48 billion.

New Chief Executive Meg O'Neill called it a "strong quarter", but said there were areas "where our performance fell short."

O'Neill, who joined BP in April from Woodside Energy, said the firm has made "good progress" strengthening its balance sheet. On Tuesday, the oil major said it was looking to offload Archaea, its US biogas business, which it bought back in 2022 for USD3.3 billion.

Strengthening the balance sheet was one of five priorities O'Neill laid out to "deliver a step change in performance."

"We need to take a clear look at ourselves: assessing what needs to change, stopping what holds us back and building strength where it matters. We have to get fit to grow," the CEO declared.

Analysts at RBC Capital Markets said clearly the "devil is in the detail, and BP will need to 'walk the talk' consistently over the coming quarters to re-build investor confidence."

"That said, ownership of BP's historical failings is a good step forward for the investment case."

In European equities on Tuesday, the CAC 40 in Paris closed up 0.6%, while the DAX 40 in Frankfurt ended up 0.8%.

Stocks in New York were higher. The Dow Jones Industrial Average was up 1.6%, the S&P 500 index was 1.3% higher, hitting an all-time best, and the Nasdaq Composite advanced 1.9%.

US markets are gearing up for results from SpaceX, its first since its initial public offer in June.

After a strong start, shares in the company which owns the Starlink satellite internet system and social media platform X, have fallen back to trade below the USD135 per share IPO price. They were up 4.6% at USD119.82 on Tuesday.

Visible Alpha consensus expects revenue of USD6.86 billion, an operating loss of USD1.62 billion and diluted losses per share of USD0.19. Attention will be on the outlook and capital expenditure, with the latter forecast to increase to USD118.4 billion in 2028 from USD48.7 billion this year.

Kathleen Brooks, research director at XTB, noted that earnings are not the only big event for the SpaceX share price this week.

On August 6, a lock up period for SpaceX shares will expire, which could more than double the tradable float of SpaceX shares, Brooks pointed out.

"Thus, tonight's numbers may not be the biggest driver for SpaceX shares," she suggested.

The yield on the US 10-year Treasury narrowed to 4.64% on Tuesday from 4.69% on Monday. The yield on the US 30-year Treasury fell to 5.20% from 5.23%.

The pound traded at USD1.3445 on Tuesday afternoon, up from USD1.3425 at the equities close on Monday. Against the euro, sterling edged up to EUR1.1674 from EUR1.1669.

The euro stood higher at USD1.1517 against USD1.1505. Against the yen, the dollar was higher at JPY157.56, compared to JPY156.78.

In London, rising metals prices underpinned the FTSE 100's gains, boosting mining stocks.

Gold was higher at USD4,078.23 an ounce on Tuesday from USD4,036.96 on Monday. Silver rose 3.0% while copper was trading 1.6% to the good compared with the same time on Monday.

Mining stocks Antofagasta, Endeavour Mining and Anglo American were prominent blue-chip gainers, up 6.9%, 3.4% and 5.5% respectively.

At the other end of the blue-chip index, Smith & Nephew fell 6.3% after cutting its full-year sales growth guidance to 4% from around 6%, as second-quarter underlying revenue growth of 1.6% missed consensus expectations due to weaker demand for US hip and knee implants.

"Not a great print and the revenue miss and lowered guidance will weight on the shares," analysts at Panmure Liberum said.

Travis Perkins stole the show on the FTSE 250, surging 18%.

The Northampton, England-based building materials distributor and retailer said it is seeing encouraging early progress in its operational turnaround as it reported better-than-expected interim operating profit.

Adjusted operating profit rose 6.3% to £67 million in the six months ended June 30 from £63 million a year before, which analysts at Stifel said was above £60 million market consensus.

But Irn-Bru owner AG Barr fell 5.4% after it said revenue was impacted by reduced stock availability, primarily from internal supply chain issues.

Elsewhere, CLS Holdings dropped 8.0% as it said full-year earnings will be below market expectations.
