We made a mock portfolio buying 100 shares of companies scoring high on the American Customer Satisfaction Index (ACSI).

These companies are in the top 20% on the ACSI scale relative to their competition, and their score is higher than the national ACSI average (75.2).

We used the same methodology as an article in the Journal of Marketing whose backtested portfolio outperformed the major indexes by 93%

We’ll monitor the portfolio and see if you can really beat the stock market by buying companies with high customer satisfaction. — BEN POPKEN
