In competitive markets, firms are rewarded by treating their customers well and punished for treating them badly. The rewards/punishments show up, not only in earnings, but also in stock prices and make equity markets better aligned with consumer utility, which, in turn, causes an upward shift in demand curves. As a result, consumer spending increases and so does economic growth.”

As the only national cross-industry measure of customer satisfaction available in the United States, the American Customer Satisfaction Index is a strategic resource for business, investment, and government communities alike.
U.S. Overall Customer Satisfaction
Quarter 1, 2025 – Over the long term, what is the stock return for companies with higher levels and greater improvements in customer satisfaction, relative to competition? ACSI researchers analyzed this using ACSI scores and stock prices of those companies from 2006 through the first quarter of 2025.
ACSI Portfolio vs. S&P 500
Companies with high ACSI scores typically do very well in the stock market. If one created a portfolio of the top 30-35 ACSI companies in their respective industries each quarter, weighted by customer satisfaction elasticity to customer retention, it would demonstrate something quite extraordinary.
