FTSE 100 Slides as JD Sports Warning and Rising Yields Shake Markets

The midcap FTSE 250 index followed the downward trend, shedding 0.3% to reach 24,575.63 points.

JD Sports' pessimistic forecast serves as a bellwether for consumer spending, amplifying concerns that the market rally may face sustained resistance in the coming weeks.
