Famed investor Benjamin Graham once wrote, “The intelligent investor is a realist who sells to optimists and buys from pessimists.” To walk the line between optimism and pessimism is the task of the prudent investor, and that is challenging when the ups and downs of the market encourage ill-advised practices such as market timing or overreliance on historical performance.

The unpredictable cyclicality of the market gives the unemotional investor the advantage to make thoughtful adjustments to a portfolio, even when consumer sentiment is historically low. Staying invested over the long term and deploying more capital when consumer sentiment is pessimistic can lead to better outcomes over full market cycles.

The Michigan Consumer Sentiment Index is a monthly measurement of the health of the economy, from the perspective of consumers. Conducted by the University of Michigan’s Institute of Social Research, it was originally created in the 1940s by Professor George Katona. Katona’s data collection process began with his researchers contacting households nationwide by phone. The index has come a long way. Today, investment managers, advisors, and economists rely heavily on the Index to gain insight into the average consumer’s attitude toward the economy.

The graph pictured below tells the story of the highs and lows of consumer sentiment from 1971 through the first half of 2022, over a half-century of data. The dark line depicts the Consumer Sentiment Index over time, with the blue dots representing the peaks and troughs over the decades. The shaded vertical bars show recessions since 1971.
