Why Reliable Consumer Ratings Matter More Than Ever
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.”

We Serve
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, 2026 – Estimates about how much has been invested to improve customer satisfaction/customer experience over the years vary, but it appears to be well over $100 billion annually with no detectable returns. If anything, the returns have been negative. Customer complaints have now reached record levels, surging by 16% in the first quarter.
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.
