What moved the S&P 500 today?

A selloff in software and data names followed news of Anthropic legal AI entering key legal tasks. Investors reassessed the defensiveness of research and drafting tools. The index closed at 6939.02, down 0.43%, with volume above average as traders trimmed exposure to names most tied to legal workflows.

How could Anthropic legal AI affect RELX share price?

If AI automates research and drafting, clients may push for lower prices or smaller seat counts. That could weigh on growth and margins. Offsetting factors include proprietary datasets, workflow integration, and compliance needs. Monitor product updates, renewal rates, and client migration before drawing firm conclusions on valuation.

What levels matter most for the S&P 500 today?

Watch 6964 as near resistance, then 6980 and 7002. On the downside, 6893 intraday support, the 50-day at 6852, and the 200-day at 6421 are important. Sustained closes above the 50-day favor buyers, while breaks below that level argue for patience and tighter risk controls.

Is Thomson Reuters stock attractive after the dip?

It depends on product stickiness, pricing power, and how AI is embedded in tools. Review guidance on renewal rates, workflow adoption, and cost savings from AI. If margins hold and churn stays low, sentiment can stabilise. Wait for management updates before making large allocation changes.
