Sticky Price CPI Inflation Expectation The dominant 64-month cycle of the Sticky Price CPI suggests higher inflation heading into 2028, followed by a decline toward 2030. Interestingly, my cycle analysis of the S&P 500 points to a market low of sorts in 2020. Note: The Sticky Price Consumer Price Index (CPI) is calculated from a subset of goods and services included in the CPI that change price relatively infrequently. Because these goods and services change price relatively infrequently, they are thought to incorporate expectations about future inflation to a greater degree than prices that change on a more frequent basis. One possible explanation for sticky prices could be the costs firms incur when changing price.
