For investors aiming to assemble a portfolio of durable, long-term holdings, the quality investing philosophy offers a useful framework. This method centers on finding companies with lasting competitive strengths, sound financial condition, and reliable earnings—businesses constructed to endure economic shifts and increase value over many years. The "Caviar Cruise" stock screen puts this philosophy into practice by selecting for firms with a record of sales and earnings increase, good returns on invested capital, solid cash flow generation, and reasonable debt. The aim is not to locate temporary discounts, but to discover superior enterprises deserving of a long-term commitment.

One company that appears from using this strict screen is Companhia Energética de Minas Gerais SA (NYSE:CIG), a Brazilian utility often called CEMIG. As an integrated participant in electricity generation, transmission, distribution, and gas distribution, CIG offers an instructive example for investors focused on quality.
The Caviar Cruise method highlights several measurable pillars of business quality. CIG’s present financial standing shows agreement with these main principles:
A look at CIG’s wider fundamental analysis report describes a company with clear positives balanced by some particular difficulties. In total, it receives a fundamental score of 6 out of 10.
CIG offers a detailed case for the quality investor. It clearly satisfies several strict numerical conditions of the Caviar Cruise screen, especially its good ROIC, outstanding cash conversion, and acceptable debt. The reality that its EBIT increase has greatly exceeded its sales increase over five years is a sign of a business enhancing its operational structure.
Still, the quality investing philosophy also weighs less measurable factors and future view. The expected near-term earnings drop, the company’s geographic focus in Brazil (with related regulatory and economic risks), and the capital-heavy, regulated character of the utility industry are significant non-numerical points. These elements may affect its competitive edge and pricing ability—main ideas of quality.
For investors wanting to use this structured method, the Caviar Cruise screen can be a useful first step. You can review the present screen outcomes and method on your own here.
To summarize, CIG displays the financial attributes of an effective, cash-producing business that matches main quality investing measures. It acts as an instance of how screens can find possibilities that justify more detailed, non-numerical investigation. A final choice to invest would need weighing these strong past financial features against a complete evaluation of the company's competitive situation, management caliber, and future possibilities inside its changing industry.
