(Sharecast News) - FTSE 250 (MCX) 24,652.69 -0.21%
IT services provider Kainos surged to the top of the FTSE 250 as it said full-year revenue and adjusted pre-tax profit were set to be "comfortably ahead" of current market expectations.
Kainos' update comes after it delivered double‑digit revenue growth, a very strong sales performance and record backlog levels in the year ended 31 March, with management stating momentum had continued through the opening months of FY27. Digital services remained a key driver, supported by several major contract wins in the second half of FY26 and further awards since the new year began. Both Workday Services and Workday Products also continued to trade well, each posting double‑digit revenue growth compared with the same period last year.
JPMorgan Japanese Investment Trust fell in line with a weaker Tokyo market overnight.
Diversified Energy, Ithaca Energy and Harbour Energy all gained on a stronger oil price.
