Materials Lag as Breadth Dries Up Across the Sector

On Thursday, September 3, the Materials sector stood apart from the wider market as breadth narrowed sharply, with only 15.4% of its member stocks advancing. While 10 of the 11 sectors rose, the exchange-traded fund Materials Select Sector SPDR Fund (XLB) slipped -0.6% to close at $52.64, and the cap-weighted sector fell -0.5%. The drop reflected internal fragmentation: gold producers rallied as bullion prices climbed alongside cooling bond yields, but broad selling across the sector offset those gains.

The divergence at the individual stock level explains the drag on the sector. Newmont Goldcorp Corp (+4.2%) led the gainers as higher gold prices supported mining shares. Modest support also came from Packaging Corp of America (+0.4%). However, widespread declines across the sector dominated trading. Albemarle Corp (-4.1%) fell after announcing a leadership succession plan that will install a new chief executive on February 1, 2027.

Breadth highlighted how widespread the weakness was below the surface. The sector's equal-weighted return of -0.9% fell further than its cap-weighted -0.5% move, showing that smaller and mid-sized constituents suffered steeper declines than the largest holdings. That uneven performance leaves XLB flat over the past month with a 0.0% return.

For investors holding Materials Select Sector SPDR Fund (XLB), the underlying quality mix shows why broad exposure was vulnerable during the session. In EasyAlpha's peer-relative grading, 43.5% of the fund's graded weight sits in companies graded A or B. Companies graded A or B have stronger fundamentals, and historically they have carried a lower risk of large drawdowns than companies graded D or E. That leaves more than half of the fund concentrated in tiers that face greater peer-relative pressure.
