FTSE 100 holds firm as Wall Street tech sell-off rattles global markets

The FTSE 100 ended the first week of June in positive territory, edging up to close at 10,368 on Friday, even as the technology-heavy Nasdaq Composite tumbled more than 4 per cent and the S&P 500 shed over 2.5 per cent in a punishing session for US equities. The divergence between London and New York was among the widest seen this year, and it offered a textbook illustration of how differently the two markets are built.

London's resilience underlined the defensive character of the UK market, which is weighted towards banks, energy and mining rather than the high-growth technology names that led the American decline. Where Wall Street's recent gains have leaned heavily on a handful of mega-cap technology stocks trading at rich valuations, the FTSE 100 derives the bulk of its value from companies whose earnings are tied to interest rates, commodity prices and global trade flows.

That structural contrast, often a source of frustration for British investors during long technology-led rallies, became an asset in a week when the most expensive corners of the US market were sold aggressively. For once, the absence of a domestic equivalent to Silicon Valley's giants worked in the index's favour.

Banks and miners lead the way

Financial stocks were among the strongest performers, with the major UK lenders all posting solid gains. Banks tend to benefit when interest rates are expected to stay higher for longer, because the gap between what they charge borrowers and pay savers widens. With markets reassessing how quickly central banks might cut rates, lenders found themselves back in favour.

Mining shares also advanced as investors rotated towards companies seen as better insulated from the turbulence in the tech sector. Commodity producers offer exposure to physical assets and dividend income, qualities that look attractive when sentiment turns away from speculative growth stories. Precious-metals miners in particular benefited from a flight to safe-haven assets.

• HSBC and Lloyds both rose around 4 per cent
• Barclays climbed close to 5 per cent
• Rio Tinto gained almost 3 per cent, with Antofagasta and Fresnillo up more than 5 per cent
• Defensive sectors such as utilities and consumer staples also held their ground

Sentiment remained cautious overall, with traders weighing elevated oil prices and uncertainty over tensions in the Middle East against the relative calm in domestic shares. Brent crude has stayed firm in recent sessions, a development that lifts the energy majors that loom large in the FTSE 100 but also raises the spectre of renewed inflation.

Analysts noted that the UK's heavier exposure to value sectors has helped the index outpace its US counterparts during periods when richly valued technology stocks come under pressure. The FTSE 100 has quietly become one of the better-performing major indices of the year, a turnaround for a market that spent much of the past decade in the shadow of Wall Street.

“When the most crowded trades in the world unwind, a market with no exposure to them suddenly looks like a haven rather than a backwater.”

Why the two markets moved apart

The immediate trigger for the US sell-off was a combination of profit-taking in artificial-intelligence-linked shares and renewed doubts about how much further valuations could stretch. After a prolonged run higher, even modest disappointment in earnings guidance or a shift in rate expectations can prompt a rapid repricing of stocks that have priced in years of flawless growth.

London, by contrast, never participated in that exuberance to the same degree. The FTSE 100's price-to-earnings ratio has long trailed the S&P 500's, a discount that has drawn complaints about chronic undervaluation but that also limits the downside when global risk appetite sours. The pound's movements add a further wrinkle: because many FTSE 100 constituents earn their revenues in dollars, a softer sterling can flatter their reported earnings.

Background: a market reshaped by global forces

The London Stock Exchange has spent recent years grappling with a wave of takeovers and a steady trickle of companies choosing to list elsewhere, fuelling anxiety about the long-term vitality of the UK equity market. Yet the same factors that critics cite as weaknesses, including the index's old-economy tilt and comparatively low valuations, are precisely what cushioned it this week.

The episode also reflects a broader recalibration under way across global markets, as investors weigh the prospect of stickier inflation, geopolitical risk in the Middle East and a more uncertain path for interest rates. In that environment, diversification away from a narrow group of technology winners has regained appeal.

What happens next will depend heavily on whether the Wall Street wobble proves to be a brief correction or the start of something deeper. If technology shares stabilise, the gap between the two markets may narrow again. But for now, the week served as a reminder that the FTSE 100's unfashionable composition can be a strength as well as a handicap, and that British investors may not always need to look enviously across the Atlantic.
