State Street Materials Select Sector SPDR ETF remains rated Hold, with valuation no longer compelling after a 20% gain since November 2025. XLB's P/E has risen to 19x, while its sector exposure is highly concentrated and increasingly sensitive to geopolitical and macroeconomic shifts. Technical signals are mixed: XLB recently failed at previous highs, with the 50dma turning down, but the primary trend remains bullish above the 200dma.
