Spread of the Day, 4/6/26: XLK - XLB

XLK (technology) rose 0.6% while XLB (materials) fell 0.4%, a 1.0 percentage-point gap.

That was a growth-over-cyclicals rotation: investors leaned into secular tech while dumping commodity-linked names as global growth sensitivity (and China/industrial demand exposure) took a hit amid volatile oil and geopolitical stress.

The divergence fits a market that’s drifting higher at the index level but with underlying macro tension—war risk lifting uncertainty while cyclicals struggle to hold bids.
