Diploma PLC share price ends week near 52-week high as UK politics loom
Diploma PLC shares ended a strong week near their 52-week peak, resisting a broader retreat in UK equities as investors continued to back the specialist distribution group’s upgraded earnings outlook. The stock added 65p on Friday to close at 7,200p. The contrast matters. Diploma gained 4.6% during a week in which the FTSE 350 fell roughly 1%, extending a run that has lifted the shares by more than a third since the start of 2026. The market is treating the company’s growth as largely self-generated rather than dependent on a broad industrial recovery.
