We made a mock portfolio buying 100 shares of companies scoring high on the American Customer Satisfaction Index (ACSI).
Using a back-tested paper portfolio and an actual case, the authors of a study published in the Journal of Marketing found that companies at the top 20% of the the American Customer Satisfaction Index (ACSI) greatly outperformed the the stock market, generating a 40% return.
We’re obsessed excited by this ACSI data so let’s slice it another way!
Here are the winners and losers on the American Customer Satisfaction Index for industries of particular interest to Consumerist readers. The scores are out of 100. Format is company name (score, difference from last year’s score).
But if the increase in quality is minor and ACSI growth is driven mostly by lower prices, or an absence of price increases, satisfaction becomes vulnerable to more volatility because prices change much quicker than quality…. Pricing power depends on upward shifting demand curves. But an upward shift is unlikely unless there is shrinking supply or higher levels of buyer satisfaction. There are no signs of the former in most industries, so the latter becomes more critical.
