Inside Materials Select Sector SPDR Fund (XLB), an exchange-traded fund tracking the sector, only 36.8% of graded assets sit in companies graded A or B against industry peers. Breadth across the group was broad on Friday, October 30, with 75.0% of member stocks advancing and the equal-weighted sector posting +0.6%. Yet the cap-weighted sector finished +0.1% and XLB closed +0.4%, held back by the group's largest names. That split was driven by opposing moves among major components: LyondellBasell Industries NV finished +5.0% and CF Industries Holdings Inc closed +4.4%, while Freeport-McMoran Copper & Gold Inc closed -5.5%. Company reports and commodity trading provided the catalyst for the moves. LyondellBasell Industries NV gained after reporting third-quarter results and agreeing to sell a Houston refinery site for $320.5 million. In contrast, Freeport-McMoran Copper & Gold Inc dropped with our sources showing no reported driver on the day.
The broader market context showed similar divergence. Materials was one of several positive areas on a day when 5 of the 11 sectors rose. The spread between the cap-weighted sector at +0.1% and the equal-weighted sector at +0.6% shows that mid-sized and smaller companies generated most of the day's strength. When smaller members outpace the largest components, the cap-weighted index records only a muted change despite positive breadth across the sector.
EasyAlpha grades the companies in the sector against their industry peers. 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. Because 36.8% of the fund's graded assets sit in those top two tiers, the remaining majority of the portfolio resides in average or below-average tiers.
Across longer horizons, performance reflects a split picture. Over the past month, XLB stands at +8.7%. Over the past twelve months, however, the fund sits at -38.8%. The steep one-year loss illustrates that despite short-term gains across individual holdings, the sector has yet to recover from its prior drawdown.

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.
