Diploma stock gains 2.89 percent as JPMorgan raises target

Diploma plc (GB0001820412) closed at 7,485 pence on the London Stock Exchange on September 21, 2026, up 2.89 percent. The move followed Sharecast reporting on September 22, 2026, that JPMorgan upgraded the shares to Overweight from Neutral and raised its price target to 8,250 pence from 5,760 pence.

JPMorgan raises the target

The revised target represents an increase of 2,490 pence, or 43.2 percent, from the previous target. According to Sharecast on September 22, 2026, JPMorgan described Diploma as a high-quality compounder capable of sustaining double-digit earnings-per-share growth into the medium term.

The target change also places the broker's revised level 765 pence above the September 21 closing price. That gap is a quantified valuation reference, not a forecast made by this article.

Price reaction sets the signal

The September 21 close of 7,485 pence was 210 pence higher than the previous close implied by the reported 2.89 percent daily gain. Diploma therefore entered the September 22 session with the broker upgrade and the 8,250 pence target as the clearest measurable market reference.

Diploma operates as a specialist technical-products group serving industrial, life sciences and healthcare markets. The available current reporting does not provide a period-specific 2026 revenue or profit figure that can be stated reliably here, so the article keeps its financial comparison tied to the dated broker target and verified market reaction.
