September 14, 2026 in numbers

Intertek Group plc (ISIN GB0031638363) ended trading on the London Stock Exchange on September 14, 2026 with only a small percent change versus its prior close, and the closing level sat comfortably between the day’s high and low, according to TradingView-linked coverage from Ad-hoc-news.

While Intertek’s own share price barely moved, the FTSE 100 advanced 0.4 percent to 10,697.57 points at the close on September 14, 2026, meaning Intertek underperformed the broader blue-chip index that day, as highlighted by Ad-hoc-news. The report also emphasized that Intertek stayed within its established trading corridor, suggesting that investors neither pushed the shares toward their 52-week high nor their 52-week low during the session.
