For investors aiming to assemble a portfolio of durable, long-term holdings, the principles of quality investing offer a useful framework. This method centers on finding companies with lasting competitive strengths, sound financial condition, and the capacity to produce steady and increasing profits over many years. Instead of looking for large discounts, quality investors are prepared to pay a reasonable price for outstanding businesses they can hold for a very long time. A structured method to start this process is with a stock screener that selects for measurable signs of quality, such as solid profitability, effective use of capital, and a sound balance sheet.

One company that appears from such a quality-oriented screen is Southern Copper Corp (NYSE:SCCO), a leading global producer of copper, molybdenum, zinc, and silver. By using a group of filters based on quality investing principles, we can assess how SCCO's financial profile matches the traits desired by long-term investors.
A basic quality screen searches for proof of past growth, high returns on capital, and financial soundness. Southern Copper shows solid results across these important measures:
A wider look at Southern Copper's fundamental analysis report supports the results from the quality screen. The company receives a high total rating, performing very well in Profitability and Financial Health.

For an investor using a quality strategy, Southern Copper offers a useful example. It works in an industry basic to global electrification and infrastructure, a possible long-term growth direction. Its top-tier resource portfolio provides a competitive edge in cost and size. The numerical screening standards—superior ROIC, solid and increasing profitability, and a strong balance sheet—all indicate a company with the traits quality investors want: stability, effectiveness, and the capacity to build value over time.
While the screen finds numerical strengths, a complete quality investing study would also think about non-numerical aspects like management's history of capital allocation, the political risks of working in Peru and Mexico, and the changing nature of commodity prices. The current high valuation also requires thoughtful study of the price paid for this quality.
Southern Copper is one instance found through a structured quality investing screen. Investors wanting to find other companies that meet similar strict financial standards can examine the screen on their own.
