Diploma trades at £71.95, which is 62% above the £27.20 our discounted cash flow model puts on the business. On that measure it screens as expensive, which is not the same as saying it will fall.

Our moat model scores it 66 out of 100, which is a moat, but not a deep one. A moat is a structural reason competitors cannot take the profits away, and it matters more to a long holding period than any single quarter's numbers do.

It changes hands at 48.2 times earnings. Be careful reading that in isolation: for a cyclical business a low P/E arrives at the top of the cycle, when profits are peaking and about to fall, which is exactly when the shares look cheapest and are not.
