On Thursday, September 17, the Materials sector closed +0.6%, supported by broad participation as 65.4% of its stocks advanced. Gains were led by Albemarle Corp (+5.1%) and International Paper (+4.4%), while Dow Inc (-2.0%) weighed on the capitalization-weighted total. The equal-weighted basket moved +0.9%, indicating that smaller and mid-sized producers outpaced the largest components. The session took place during a broad market advance in which 10 of the 11 sectors rose. The sector gained as lower oil prices and declining Treasury yields buoyed basic materials. That move coincided with a wider rally where broader equity markets staged their strongest session in weeks. In related corporate news, one industrial manufacturer announced a facility expansion.
Fund Vehicle and Quality Mix
The primary vehicle for the sector is Materials Select Sector SPDR Fund (XLB), an exchange-traded fund that closed +0.7% at $50.73. EasyAlpha grades the individual companies in the sector against their industry peers. Currently, 30.5% of the fund's graded weight sits in companies graded A or B. Historically, companies in those top tiers have demonstrated stronger fundamentals and experienced a lower risk of large drawdowns compared to companies graded D or E.
Longer-Term Trend
The session's modest advance follows an extended stretch of mixed performance across basic materials. Over the past month, the fund stands -2.0%, matching its -2.0% move across recent sessions. Over longer horizons, the fund sits +6.3% over the past six months, but remains -44.2% over the past twelve months. While softening energy prices and bond yields provided immediate relief on Thursday, September 17, the fund's longer trajectory reflects ongoing challenges across basic materials.

How grades work
Every day we grade each company against the other companies in its sector, looking at its finances, how its stock trades, and what the market is signaling. The result is one simple letter.
- AExcellent quality
- BGood quality
- CAverage quality
- DBelow average
- EWeakest quality
A grade measures quality against the other companies in a sector, from historical data. It is not a prediction, not a price target, and not advice. A company can be graded A and still fall.
