GlobalData Share Price Slide Continues Despite FTSE 250 Promotion

Shares in GlobalData (LON: DATA) fell sharply on Monday, adding to the recent decline as investors continued to sell into the news of the data intelligence company’s inclusion in the FTSE 250 Index, with the stock dropping 5.3% to 80.7p.

The sell-off marks a painful irony for the London-listed firm, which confirmed its entry into the mid-cap benchmark following FTSE Russell’s latest quarterly review.

Despite the milestone, shares have retreated since the announcement in early June, touching a session low of 80.7p on volume of more than 1.6 million shares on Monday.

Open Account Spread bets and CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. 68% of retail investor accounts lose money when trading spread bets and CFDs with this provider. You should consider whether you understand how spread bets and CFDs work, and whether you can afford to take the high risk of losing your money.

The stock has now shed around 27% from its early-June high of 110p, suggesting investors had already priced in the promotion ahead of its formal confirmation.

The FTSE 250 inclusion caps a period of rapid progress for GlobalData. The company moved from AIM to the Main Market of the London Stock Exchange in March 2026, and its latest promotion broadens its exposure to a wider institutional investor base.

Mike Danson, CEO of GlobalData, said the milestone “reflects the strength of our business, the progress we have made together, and the confidence the market has in our future,” adding that the achievement belongs to colleagues across the business.

Jonathan Hardinges, Chief Strategy Officer, described the progression from AIM to the Main Market and now the FTSE 250 as underscoring “the scale and maturity of the platform we have built,” calling it “a foundation for our next phase of growth.”

GlobalData, whose productivity and intelligence platform serves over 5,000 organisations worldwide, said it will continue to invest in its connected platform and AI capabilities in line with its Growth Transformation Plan.
