GSK stock closed at GBP 1,877.50 on the London Stock Exchange on September 18, 2026, losing 1.2% from the prior session.

September 18, 2026 in numbers
GSK plc (ISIN GB0009252882, LSE: GSK) ended the last completed London session on September 18, 2026 at GBP 1,877.50, down 22.50 pence or 1.18% on the day, after moving between a low of GBP 1,852.50 and a high of GBP 1,912.00, with reported turnover near 15.67 million shares. According to United Kingdom share tables from a major market portal, this placed the close below the upper end of GSK's recent trading band while the broader FTSE 100 index finished little changed on the same date, so GSK underperformed its home benchmark in that session.
As IT-Boltwise reported on September 20, 2026, Berenberg recently upgraded its view on GSK and lifted its price target to GBP 22, citing confidence in the pipeline and earnings outlook. The same report noted that the shares had shown relative stability around current levels following the recommendation change, suggesting that analyst commentary remains a relevant factor for trading interest even when the stock posts a modest daily decline.
