Halma plc

“Halma is a structurally exceptional serial acquirer — regulation-mandated end-markets, niche dominance, 46 years of dividend growth, and an inexhaustible M&A pipeline — but at 35x forward adjusted earnings and 8.5x book, the market has already priced in a decade of flawless execution, compressing the probability-weighted 5-year total return to roughly 4% annualized with meaningful downside if organic growth disappoints; the right response is to admire the business, build a position only on a 20-30% drawdown to the 25-28x forward P/E range, and hold without adding if already owned.”
