FTSE 100 Live: UK stocks in the red ahead of flat Wall Street open
FTSE 100 was down about 30 points near 10,801 as miners fell after Antofagasta cut 2026 copper output guidance to 625,000-655,000 tonnes. JPMorgan upgraded Aviva to overweight and downgraded Legal & General and M&G. UK Q2 GDP grew 0.4%. Investors awaited US producer prices and jobless claims; US inflation eased to 3.4% in July.
How this was made
The 30-second read
Why it matters
Traders can act on two concrete inputs: (1) insurer relative-value positioning via JPMorgan’s upgrade/downgrade package, and (2) copper-miner risk via Antofagasta’s 2026 guidance cut and its weather-related operational cause. The rest of the market tone is framed around US PPI and jobless claims affecting Fed rate expectations.
Market read
Company-specific rating and guidance changes are driving sector rotation, while US inflation and upcoming PPI and jobless claims are setting the macro rate backdrop.
What to watch
The article notes Goldman downplayed the DRC copper concentrate ban impact; if that view gains traction, copper-sensitive miners could rebound even if near-term guidance remains pressured.
Background
The piece is a live-style UK market wrap with specific company catalysts: a JPMorgan insurance coverage reshuffle and Antofagasta’s production guidance cut, plus macro context from easing US inflation.
Ticker impact
JPMorgan reiterated Standard Life as overweight while upgrading Aviva and cutting other UK life insurers.
Mild near-term positive bias, mainly relative to the downgraded group.
The article reiterates the rating but does not provide a new Standard Life-specific catalyst beyond the sector-relative valuation framework.
Rio Tinto fell 4.08% as the mining sector sold off after Antofagasta’s production guidance cut.
Near-term downside pressure likely to track copper sentiment and sector flows.
The article reports Rio’s price move but does not cite a Rio-specific new fact; linkage is indirect via sector read-across.
Anglo American fell 2.59% as copper-related guidance and metals momentum drove broader mining weakness.
Slight-to-moderate downside bias while copper sentiment remains pressured.
The text attributes the broader decline to Antofagasta and metals dynamics, not a new Anglo American fact.
The article says strong earnings from Amazon helped support the UK market bounce ahead of the Wall Street open.
No direct trading edge from this article for AMZN; any impact is indirect via sentiment.
No new Amazon earnings figures or guidance are provided, only a general statement that earnings were strong.
The article cites strong earnings from Microsoft as part of the backdrop supporting the market bounce.
No direct trading edge for MSFT from this article alone.
The text does not provide new MSFT data, guidance, or a fresh catalyst.
CoreWeave is cited as jumping on 112% revenue growth, with the move linked to AI infrastructure trade strength.
Positive spillover risk for AI-exposed portfolios; direct trading edge depends on CoreWeave’s own tape reaction.
The article provides a concrete growth figure (112% revenue growth) tied to CoreWeave’s jump, which is a specific catalyst.
Super Micro is mentioned as having more than doubled earnings estimates, contributing to the AI infrastructure trade.
Near-term positive bias for AI infrastructure sentiment, though SMCI is not the article’s primary subject.
The article provides an estimate-change claim but does not detail timing, source, or magnitude beyond the qualitative 'more than doubled' framing.
Nvidia is cited as adding 2.7% as part of the AI infrastructure trade supporting Scottish Mortgage.
Supports risk-on in AI complex; limited standalone edge for NVDA.
The article reports a price move and portfolio linkage, without new NVDA-specific disclosures.
Market effects
Copper guidance cuts and metals momentum reversal pressure the resources complex; insurer rating reshuffle can drive relative-value rotation within UK life insurance.
FTSE 100 direction is tied to US rate expectations (PPI and jobless claims) and to UK insurer positioning.
US inflation easing and AI complex strength influence global long-duration growth sentiment, spilling into UK growth-oriented portfolios.
Counterpoint
The Antofagasta guidance cut is weather-driven and may be partially reversible, so the sector read-across could overstate longer-term copper supply risk.
