EasyAlpha grades the stocks in the Materials sector against their industry peers, with 41.9% of the group's graded weight landing in the higher-quality A or B tiers. On Wednesday, October 7, breadth was exceptionally thin: only 11.5% of the sector's S&P 500 members managed to gain ground. The Materials Select Sector SPDR Fund, an exchange-traded fund that tracks the group under the ticker XLB, closed -1.5% at $48.98, matching the broader cap-weighted sector move of -1.5%. An equal-weighted reading of -1.4% showed that the largest constituents drove more of the decline. The session's primary drag came from The Mosaic Company, which finished -4.7%, while Corteva Inc bucked the trend to end +3.9% and International Flavors & Fragrances Inc finished +0.3%. Pressure built as declining prices for copper, gold, and silver pulled down producers across the board.
Shares of The Mosaic Company fell following an analyst downgrade that cut expectations because of a prolonged recovery timeline in phosphate markets. In contrast, Corteva Inc stood out as an exception after an analyst upgrade highlighted product pipeline momentum that could bolster earnings in future years. Elsewhere in the sector, capital spending continued despite the day's downturn, as PPG committed to a $70 million investment to expand its aerospace operations in Huntsville, Alabama. Yet positive project commitments and isolated upgrades were not enough to counter the broader retreat across basic materials.
Across the broader market, only 3 of the 11 sectors rose. For the materials fund, Wednesday's drop extended a difficult stretch. Over the past month, the fund stands at -5.7%, and its twelve-month performance sits at -45.2%. The fund carries an expense ratio of 0.08%, but that holding cost does not insulate the portfolio from broader downturns.
Across the sector, 41.9% of the fund's graded weight sits in companies graded A or B against industry peers. In EasyAlpha's historical research across industry peers, companies graded A or B have shown stronger fundamentals and carried a lower risk of large drawdowns than companies graded D or E. That historical finding describes relative quality rather than a guarantee against losses, and a higher grade does not prevent an individual company from falling during broad market pullbacks.

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.
