Rockwool’s updated margin outlook came right as the stock is navigating a tough stretch. The 1-month share price return is -13.1% and year-to-date the stock is down nearly 20%. Despite the recent slide, its 3-year total shareholder return is still comfortably positive, which hints at longer-term resilience even as near-term momentum fades.
