From the 2005 Main page of The Economic Fractalist : “A sudden nonlinear drop in the last 0.5x time period of the 2.5X is the hallmark of a second cycle (SECOND FRACTAL) and characterizes this most recognizable cycle.”

The 1807 36/90/90/54 year :: x/2.5x/2.5x/1.5x fractal cycle ending in 2074 had in the terminal portion of its 90 year 2.5x second cycle or fractal ending in 1932, relative nonlinearity in equity and commodity valuations from 1929 to 1932.

After a 1932 10+/21-22/21-22 year :: x/2x/2x growth fractal ending in 1982, a 13/ 32 year interpolated 1st and 2nd fractal series from 1982 to 2025 is expected to end in a relative nonlinear devaluation of equities and commodities. The 90 year 2nd Fractal ending in 1932 with a 36 year first fractal occurred over 32 months from its final peak to its nadir. With a 1982 year 13 year first fractal, by proportionality, this might occur in 9-10 months.
Below are four first and second fractal series dating from about 1982, March 2020, and 27 October 2023.
The first is composed of a 1982 49-51 quarter/ 126 quarter :: x/2.5x first and second fractal series ending in about June 2025.
The second is a March 2020 19/39 of 46-48 month :: x/2-2.5x first and second fractal series.
The third is a 27 Oct 55/139 day :: x/2.5x first and second fractal series ending on 5 August 2024.
The fourth is a 27 Oct 74/185 day :: x/2.5x first and second series ending 5 November 2024.

A 1982 49-51 quarter/ 126 quarter :: x/2.5x first and second fractal series ending in about June 2025. the first 49-51 quarter fractal is composed of a 10/25/16-18 quarter fractal series. The last three quarters of the 51 quarter first fractal appears to be shared with the 126 quarter 2nd fractal. The 126 quarter second fractal is composed of a 60 quarter sub cycle and a 67 quarter subcycle as below.

The first 60 quarter subcycle of the second fractal of a 1982 49-51 quarter/ 126 quarter :: x/2.5x first and second fractal series ending in about June 2025.

The second 67 quarter sub cycle of the second fractal of a 1982 49-51 quarter/ 126 quarter :: x/2.5x first and second fractal series ending in about June 2025.

A March 2020 19/39 of 46-48 month :: x/2-2.5x first and second fractal series.

A 27 Oct 55/139 day :: x/2.5x first and second fractal series ending on 5 August 2024.

A 27 Oct 74/185 day :: x/2.5x first and second series ending with an initial crash on 5 November 2024 and continuing with lower growth and greater decay cycles with a nadir in about June 2025.
