Costco's Sales Rebound in September Looks Great on Paper. Why There's More to the Story. -- Barrons.com

October 9 - RBC expects the performance of most European building material products to gradually improve quarter-on-quarter in Q3, but notes that geopolitical uncertainties in the US will continue to drive up cost inflation and increase market volatility. RBC anticipates that sales in Europe will remain sluggish due to heatwaves and rising mortgage rates, while a weak US housing market and the lack of a significant hurricane season will prompt roofing material companies to enter a destocking cycle.
