XLB maintains a long-term BULL trend and a short-term UP signal, though the September 9 session ended in retreat — the ETF slipped $0.55 to close at $51.39, a decline of 1.06%, on volume of 13.1 million shares, running well above the 10.8 million average. The FUM Score of 48.12 signals moderate technical strength. The current UP trend has been in place since July 30, and while it holds, price sits below the FUM fast moving average of $52.41, putting near-term resistance squarely in focus for the materials complex.
