NEW YORK ( TheStreet) -- Quanex Building Products (NYSE: NX) has been downgraded by TheStreet Ratings from buy to hold. The company's strengths can be seen in multiple areas, such as its revenue growth, largely solid financial position with reasonable debt levels by most measures and solid stock price performance. However, as a counter to these strengths, we also find weaknesses including unimpressive growth in net income, poor profit margins and weak operating cash flow.

Its Engineered Products segment produces window and door components for original equipment manufacturers that primarily serve the residential construction and remodeling markets. The company has a P/E ratio of 30.6, below the average materials & construction industry P/E ratio of 32.1 and above the S&P 500 P/E ratio of 23.5.
