The SPX base 1st decay fractal starting from the SPX secondary high 12 October 2026 will be exactly the same as from the SPX 3 Sept 1929 peak valuation: 7 days.

3 Sept 1929 to 13 Nov 1929: 7/18/18/10 days :: y/2.5y/2.5y/1.5y

12 Oct 2026 to 10 December – 22 December 2026:
7/15-18/15-18/9-10 days : y/2-2.5y/2-2.5y/1.5-1.6y(y’)

The 43 day second fractal low of a 29 July 2026 17/43/37-44 day :: x/2.5xy/2-2.5xy fractal series will occur on 20 Oct 2026 ending 1230 -330 EST.

Hourly fractals from the 5 hour 1230 EST 9 Oct to 930EST 12 Oct 1st 5 hour fractal:

5/10/13 hours :: y/2y/2.5y ending 930 EST 15 Oct 2026 then

4/10/8-10/6-7 hours :: y/2.5y/2-2.5y/1.5-1.6y ending 1230-330 EST 20 October.

For the SPX composite a nonlinear lower low gap is expected between Friday 16 October and Monday 19 October 2026. 19 October concludes the 42 day second fractal of a 29 July 2026 to 9 December 2026 17/42/37 day :: xy/2-2.5xy/2-2.5xy (of a SPX 1982 13/33-4 year :: x/2.5x 1st and 2nd fracal series) terminal 3-phase peak valuation growth and initial crash decay Lammert fractal series. Interpolated within this series is a (secondary SPX lower high peak valuation occurring on) 12 October 2026: 6/15/15/9 day :: y/2.5y/2.5y/1.5y, a 4-phase Lammert fractal decay series ending on 9 December 2026. This is fractally self similar to the 1929 3 September 1929 peak valuation and initial 13 November 1929 crash decay as described in the previous post.

The Lammert hourly fractal pattern predicted for 19 October 2026 is depicted above. Two hourly decay fractal series are shown above: a completed 5/10/13 hour :: y/2y/2.5y 3-phase fractal decay series with a 5 hour 1st fractal starting on 1230 EST 9 Oct 2026 and ending 930 EST 12 October 2026 and the 13 hour 3rd fractal ending 930 EST 15 Oct 2026.

The 3/8/5 of 8/4-5 hour :: y/2.5y/2.5y/1.5-1.6 4-phase fractal decay series starts on 930 EST 15 Oct 2026 and ends on 230-330 EST 19 October 2026 with an expected nonlinear lower low gap between 330 EST 16 October and 930 EST 19 October and between day 41 and day 42 of the 2nd Fractal of the 29 July 2026 to 9 Dec 2026 17/42/37 day :: xy/2-2.5xy/2-2.5xy SPX Lammert 3-phase peak valuation and initial crash decay series.

From the 2005 main web 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 (fractal)and characterizes this most recognizable cycle(fractal)...

6 October 2026 concluded the SPX’s peak valuation growth in a 1982 to 2026 13/33-34 year :: x/2.5x 1st and 2nd fractal series, an interpolated series within a US hegemonic 1807 36/90/90/54-57 year :: x/2.5x/2.5x/1.5-1.6x 4-phase fractal series.

The SPX 1929 peak valuation on 3 Sept 1929 was near the end of a 1807 36/90 year :: x/2.5x 1st and 2nd fractal series which ended at year 90 (2.5x)in 1932.

The above depicts the Aug to Nov 1929 12/29/27 day :: xy/2-2.5 xy/2-2.5xy 3-phase fractal series that contains the 1807 :: 36/87 x/2-2.5x 3 Sept 1929 peak valuation and initial 13 Nov 1929 crash nadir valuation decay.

From the 3 Sept 1929 peak, a 7/18/18/10 day :: y/2.5y/2.5y/1.5y 4-phase fractal decay series ends at the initial crash nadir on 13 November 1929.

The above depicts the current fractal model of a 1929 self similar SPX 29 July 2026: 17/42/37 day :: xy/2-2.5xy/2-2.5xy with a 1982 13/33 year :: x/2.5x peak valuation on 6 Oct 2026, a secondary peak on 12 Oct 2026 and an initial crash nadir on 9 December 2026.

The 29 July to 20 Aug 2026 17 day 1st fractal is composed of a 3/8/8 day 3 phase fractal series. The 20 Aug 42 day 2nd fractal ending Monday 19 Oct 2026 is composed of two 4-phase fractal subseries: a 20 August 3/7/7/5 day series ending 16 Sept 2026 and a 16 Sept 4/9/8/6 day series ending Monday 19 Oct 2026.

From the SPX secondary peak on 12 Oct, day 8 of the 3rd 8 day fractal of a 1 Oct 4/9/8 day 3-phase growth fractal series, a 6 day 4th fractal ends on the 16 Oct 2026 42 day 2nd fractal nadir. A 4-phase y/2.5y/2.5y/1.5y : 6/15/15/9 day fractal series ends on the 9 December 2026 nadir.

The above daily 29 July 2026 to 9 December 2026 fractal series completes a 7 April 2025 17/36/37 week :: xy/2-2.5xy/2-2.5xy fractal series. The 37 week 3rd fractal is composed of a 30 March 2026 6/13/12/9 week :: x/2-2.5x/2x/1.5x 4 phase fractal series corresponding to a 30 March 2026 25/60/57/37 day :; x/2-2.5x/2-2.5x/1.5x 4-phase fractal series. The 3-phase xy/2-2.5xy/2-2.5xy 29 July 2026 to 9 Dec 2026 daily peak valuation and initial crash to nadir value fractal series is fractally self-similar to the 7 April 2025 to 9 Dec 2026 weekly 3-phase xy/2-2.5xy/2-2.5xy peak valuation and initial crash to nadir valuation fractal series.
