FTSE 100 movers: Relx, Experian, LSEG tumble on Anthropic AI tool; miners shine

(Sharecast News) - London's FTSE 100 was down 0.7% at 10,272.07 in afternoon trade on Tuesday. Relx, Experian, LSEG, Informa and Pearson all slid as US AI company Anthropic released an AI-powered productivity tool for companies' in-house legal teams.

On its website, Anthropic described the tool as an AI-powered productivity plugin for in-house legal teams, primarily designed for its agentic desktop application Cowork, although it also works in Claude Code.

The tool is part of 11 plugins designed to automate specific tasks within a company.

According to the GitHub page, the legal productivity plugin can "review contracts, triage NDAs, navigate compliance, assess risk, prep for meetings, and draft templated responses". All of this is configurable to an organisation's "specific playbook and risk tolerances," it said.

Elsewhere, JD Sports was under the cosh as Deutsche Bank cut its price target on the stock to 85p from 95p and kept its 'hold' rating as it said the retailer was "running against the trend". It said that beyond the Nike comeback, there are three fashion trends it is watching that suggest potential for ongoing downside risk to JD's demand outlook.

On the upside, heavily-weighted miners Anglo American, Antofagasta, Rio Tinto and Glencore all rallied as metals prices recovered from the recent selloff, with precious metals miner Fresnillo also up as gold and silver prices bounced back.

Chilean copper miner Antofagasta was also in focus after Morgan Stanley downgraded the stock to 'underweight' from 'equalweight' and reduced the price target to 3,050p from 3,070p.

In a broader note on metals and mining, the bank said it was turning "more cautious on the pure plays" against a backdrop of record valuations and softening copper micro drivers.
