JD Sports Fashion cut its fiscal 2027 profit guidance after weaker-than-expected second-quarter trading, with like-for-like sales down 3.1% and North America declining 6.8%. The retailer now expects profit before tax and adjusting items of £700 million to £800 million. Analysts at Citigroup, UBS and Shore Capital reacted cautiously, keeping neutral stances after the update as the company pointed to pressure in its key North American market and softer trading momentum. JD Sports shares fell nearly 15%, weighing on the FTSE 100, while broader UK markets were also pressured by higher long-dated bond yields. Oil prices rose, supporting BP and Shell, and other notable decliners included Trainline and Ashtead Technology.
