On Thursday, September 10, Mueller Industries Inc shares fell 5.6% to close at $60.16, marking its largest single-session drop since Tuesday, July 21. The sharp decline occurred without major operational news, even as disclosures showed institutional funds increasing their holdings, as the stock was swept up in a broad market selloff. Equities pulled back after producer prices rose 0.4% in August and 5.4% over the prior year, reigniting concerns over persistent inflation and driving Treasury yields higher.
Market sentiment weakened further as higher oil prices and climbing bond yields weighed on equities. At the same time, copper-related shares faced selling pressure as copper prices retreated from record levels amid tariff uncertainty.
Thursday's drop adds to an extended downturn for the stock, which is -12.1% over the past month and -47.6% so far this year. EasyAlpha currently grades Mueller Industries Inc C compared to its industry peers in the top 1,000 U.S. companies, down from A in the previous evaluation. Grade C denotes average quality, placing the company in line with typical 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.
The company maintains solid profitability, highlighted by an 18.2% profit margin, and its balance sheet remains sound with debt load ranking as its primary strength. However, weaker peer-relative marks in earnings quality explain why the quality grade settled at C. At Thursday's close, the stock trades at 16.6 times trailing earnings.

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.
