The 2 November 2026 Initial SPX Crash Nadir, a SPX Terminal-Growth-to-Peak-Valuation-and Initial-Crash Fractal Series “Exact” Replica of 1929.

The current Fractal Model for the US SPX is a 3-Phase terminal Peak Growth and Crash Decay Model which reaches its nadir on Monday 2 November 2026, the day before the US congressional midterms. Fractally it is exactly, to a day, following the 1929 11/26/27 day :: xy/2.5xy/2.5xy peak valuation and inital crash fractal decay series which ended on 13 Nov 1929.

A 2 November 2026 Crash Nadir, a day before the midterms:
Woowee … God doth have a sense of humor…



In the above 1929 SPX daily fractal graph, the fractal time unit ‘xy’ is used to denote terminal fractal peak valuation growth and initial crash decay. The last 3 days of the 7 day 3rd fractal of a pre-terminal 3/8/7 day :: x/2.5x/2-2.5x 3-phase fractal growth series is shared (conjoined) with the first 11 days of a 11/26/27 day :: xy/2.5xy/2.5xy 3-phase fractal series in which 3 Sept 1929 is contained in the 26 day 2nd fractal and day 27 of the 27 day 3rd fractal is the nadir 13 Nov 1929 crash low.

In the above 2026 daily fractal graph, the fractal ‘xy’ notation is again used to denote terminal fractal peak valuation growth and initial crash fractal decay. The last 3 days of the 4th fractal of a pre-terminal 29 July 2026 2/4/4/3 day 4-phase fractal series is shared (conjoined) with following 8 days of a 2/5/3 day fractal series to form a 10+/11 day 1st fractal (day 1 of the 10 day series is upgoing and double counted.) A 10+/26/27 day :: xy/2.5xy/2.5xy 3-phase fractal series in which 13-14 August 2026, the SPX all-time peak valuation, is contained in the 10+/11 day 1st fractal and day 27 of the 27 day 3rd fractal is the crash nadir occurring on Monday 2 November 2026.

Below Added 1055 EST 18 Sept 2026:

The comparison weekly 1928 and weekly 2025 fractal charts are shown below.

From the 20 Feb 1928 nadir to the 13 Nov 1929 initial crash nadir the DJIA and SPX self-assembled in a 26/66 week :: x/2-2.5x 1st and second fractal series part of a 3 phase x/2-2.5x/2-2.5x :: 26/66/58 week 3-phase fractal series. Three weekly fractal series make up the 66 week 2nd fractal: a 4-phase 3/7/7/3 or 18 week series, a 5/12/10 week or 25 week series ending 27 May 1929 and a 27 May 1929 3 phase 25 week, 5/12/11 week fractal series with 2 weeks of the 2nd 12 week fractal shared with the 3rd 11 week fractal. The 12 week 2nd fractal is composed of of a 2/5/5/3 week series and the terminal 11 weeks series is composed of a 2/4/5/3 week series.

On a weekly basis, the 2026 SPX fractal series is following a terminal 17/35/32 week :: x/2-2.5x/2-2.5x’ fractal series with a peak valuation on week 20-21 or 1.5x’ of the terminal 32 week 3rd fractal and ending with a initial crash low on week 32 or 2 November 2026.

A Fractal Primer on the two laws of Asset-Debt Saturation Macroeconomics, Fractal Series, and Elemental Fractals

1st Law/Pattern: a 3-phase time-based fractal series: x/2-2.5x/1.5-2.5x growth and decay
2nd Law/Pattern: a 4-phase  time-based fractal series: x/2-2.5x/2-2.5x/1.5-1.6x growth and decay

Each element of the above two series is  termed ‘1st’, ‘2nd’, and ‘3rd’ Fractal and ‘1st’, ‘2nd’, ‘3rd’,and ‘4th’ Fractal, respectively

Fractal groupings are generally determined by straight or curvilinear underlying slope terndlines

The 2nd 2.5x Fractal of the 3-phase and 4-phase fractal series determines the ideal “x'” 1st fractal whose ideal time length  equals the time duration of the 2nd Fractal divided by 2.5; this ideal length “x'” then determines the expected length of the 3rd and 4th Fractals

The  Asset Valuation Self-Assembly Process and the Grand US Hegemonic 1802  Fractal Series Cycle: 

Equity and commodity price cycles are deterministic and self-assembled in regular time-unit based simple mathematical  above fractal patterns representing the macroeconomic asset-debt system’s most efficient manner of trading valuation growth during times of ongoing government deficit spending and  during times of excessive private debt investment, the latter resulting in  overproduction and over valuation of asset to a retrospectively recognizable peak asset valuation – and thereafter asset valuation decay occurs with  ongoing debt default and unpayable debt reorganization. Targeted eras of excess private credit and overvalued assets are 1630’s tulips; 1720 south sea certificates; mid-1840’s Britain and early 1870’s US railway stocks; 1929 equities with 10% margin buying; and equities associated with the 2000 internet innovation mania, US 1830’s and 2000-2007 real estate manias, and  the 2025-2026 AI/data center manias. For the US, the great fractal cyclical time-unit framework is a 1807 36/90/90/54-57 year :: x/2.5x/2.5x/1.5-1.6x 4-phase fractal cycle ending in 2074-2077.  The 1807  36 year 1st  Fractal ended in 1842-3 and the 90 year 2nd Fractal in 1932. The 90 year 3rd Fractal and  the 54-57 year 4th Fractal of the 1807 36/90/90/54-57 year fractal series are composed of 2 sequential fractal series: a 51 year 1932 10-11/21/21 year :: x/2x/2x series ending in 1982 and a 1982 96-97 year 13/33-34/33/20 years :: x/2.5x/2.5x/1.5x fractal series ending in about 2077. The 90 year 3rd fractal peak valuation is interpolated in the 13/33-34/33/20 year series and occurred in Nov 2021.  11-14 % Covid -related GDP deficit spending and  subsequent 6-8% GDP deficit spending (the peacetime  average before 2009  is 3%) and chip/AI/data center mania private spending  in 2025 and 2026, accounting for  40-90% of  US GDP growth, extended the 3rd fractal 90 year cycle to the end of the 1982 13/33 year cycle.

Comparisons of 1928 to 1929  with  2025 to 2027: expansion of private debt; national deficit to GDP ratios, and SPX and DJIA equity blow-off 
valuation gains:

1928 to 1929


From the end of 1927 to 1929 US non-mortgage private consumer credit expanded by 30% from 5.7 to 7.6 billion dollars. Most automobiles, appliances, and radios were purchased on installment plans with private credit. GDP rose 8.4% or 95.5 billion to 104.6 in those two years or 4.2% per year. The non-mortgage private consumer credit expansion accounted for 25% of the increase of the GDP in 1928 and 1929. US governmental debt was 18.5 billion in 1927 and dropped to 16.9 billion in 1929, the latter 14.8% of GDP. As consumer credit and private debt rapidly expanded by 30% during 1928 and 1929, DJIA valuation in the interval between its 20 Feb 1928 nadir valuation and its 3 Sept 1929 peak valuationthe , witnessed an increase of 87.45% from 203.35 to 381.17.

2025 to 2026

Unlike the 1928 to 1929 period where the US national debt decreased by 9%, the national debt increased from 34.1 trillion to 40 trillion from the beginning of 2025 to Aug 2026 and is expected to be 41.5 trillion by Dec 2026, a 21.7% increase in 2 years and 10.85% increase on annual average. GDP in that same time span rose from 29.30 trillion to an expected 31.48 trillion or 2.18 trillion by 2026 year’s end: or nominally in the two year span by 7.4% or 3.7% annually. Private credit expansion in AI/hardware/software/data centers has accounted for an estimated 40-90% of the increase in the 2.18 trillion increase in GDP. Current federal governmental debt to GDP stands at 123% as opposed to 14.8% in 1929.

Following the executive order announcement of tariffs, later deemed to be unconstitutional, the DJIA and SPX eventually reached nadirs on 7 April 2025 at 37,965.60 and 5062.25, respectively. After the administration’s non-congressionally approved initiation of the Iran war on 28 February 2026 and sharp oil price increases, the DJIA and SPX declined to a higher nadir low on 30 March 2026. With a temporary cessation of military activities the DJIA reached a peak valuation on 5 August 2026 at 54744.33 and the SPX on 13-14 Aug 2026 near 7800 representing a 35% increase and a 30.6% increase, respectively. The NASDAQ containing AI stocks had a 45.4 % gain from its 7 April 2026 intraday low of 14849.96 to its 1 June 2026 intraday high at 27190.21. Percentage-wise the terminal 7 April 2025 to 2026 equity blow-off gains were less than 43% of the terminal 20 Feb 1928 to 1929 gains. The great percentage difference between peak SPX valuations 3 Sept 1929 and 13 August 2026 may have been the ongoing man-made diesel, oil, natural gas, helium, sulfuric acid, copper global supply shock shortages which in themselves will ultimately have an estimated 10% negative effect on global GDP. The Ongoing shortages will have a profound synergistic effect on the natural over-investment fractal decay cycle.

Which political party will be blamed for the Monday 2 November initial Crash Nadir?

It is the opinion of this economic fractalist that without presidential involvement, the final peak valuations for the SPX/DJIA would have been higher, but that the timing of the Monday 2 Nov 2026 crash nadir would have been the same. The superimposed synergistic effect of the Iranian oil, helium, fertilizer,et. al. global supply shocks (and the US mutable, unpredictable trade policies) – on the natural fractal peak and decay pattern of terminal private funding mania, asset overinvestment,  over production and overvaluation –   will result in an initial lower 2 November 2026 global equity composite crash nadir valuation.

{In the following posting, compare the numerous daily, weekly, yearly empirical fracta charts shown below with this simple primer on the two self-assembly laws of Lammert time-unit based fractal macroeconomcs:

One: a 3-phase fractal series: x/2-2.5x/1.5-2.5x growth and decay
Two: a 4-phase fractal series: x/2-2.5x/2-2.5x/1.5-1.6x growth and decay

(This website promotes the concept that equity and commodity price cycles are deterministic and self-assembled in regular time-unit based simple mathematical fractal patterns representing the macroeconomic asset-debt system’s most efficient manner of trading valuation growth during times of gradual and times of excessive private debt investment, the latter with overproduction and over valuation to peak asset valuation – and thereafter asset valuation decay with debt default or unpayable debt reorganization. Targeted eras of excess private credit and overvalued assets are 1630’s tulips, 1720 south sea certificates, mid-1840’s Britain and early 1870’s US railway stocks, 1929 equities, and equities associated with the 2000 internet innovation manias, US 1830’s and 2000-2007 real estate manias, and 2025 AI/data center manias. For the US, the great fractal cyclical time-unit framework is a 1807 36/90/90/54-57 year :: x/2.5x/2.5x/1.5-1.6x 4-phase fractal cycle ending in 2074-2077.)

The 8 July 1932 SPX and DJIA nadir completed the US 1807 36/90 year :: x/2.5x 1st and 2nd fractal series with a 1st fractal low in 1842/43 after the massive state-bank-owned credit expansion and real estate overvaluation in the 1830’s, ending in the panic of 1837 with 5 to 6 years for bad debt and asset valuation recalibration.

The 90 year 3rd fractal and 54-57 year 4th fractal of the 1807 36/90/90/54-57 year fractal series are composed of 2 sequential fractal series: a 51 year 1932 10-11/21/21 year :: x/2x/2x series ending in 1982 and a 1982 96-97 year 13/33-34/33/20 years :: x/.5x/2.5x/1.5x fractal series ending in about 2077. The 90 year 3rd fractal peak valuation is interpolated in the 13/33-34/33/20 year series and occurred in Nov 2021.

Qualitative Economic Conditions: The 1928 SPX /DJIA Composite Equity Low to the 1929 Blow-0ff Peak Valuation: 20 Feb 1928 to 3 Sept 1929

Qualitative Economic Conditions: The SPX 2025 Composite Equity Low to the 2026 Equity Blow-off Peak Valuation: 7April 2025 to 13 Aug 2026

Unlike the 1928 to 1929 period where the US national debt decreased by 9%, the national debt increased from 34.1 trillion to 40 trillion from the beginning of 2025 to Aug 2026 and is expected to be 41.5 trillion by Dec 2026, a 21.7% increase in 2 years and 10.85% increase on annual average.

1928 and 2025 Quantitative Fractal Comparisons

The Weekly Self-assembly Fractal Progression of the DJIA/SPX 20 Feb 1928 Higher Low Nadir to the 3 Sept 1929 Peak Valuation and to the Initial 13 Nov 1929 Crash Nadir and to the Final 8 July 1932 Crash Nadir … And the Current 7 April 2025 to 15-23 Oct 2026 x/2-2.5x/2-2.5x’ 3 Phase Fractal Series: Weekly and Daily Fractal Self- similaritiy to the initial 13 Nov 1929 crash nadir.

The 20 Feb 1928 to 13 Nov 1929 18/41/34 x/2-2.5x/2-2.5x’ Fractal Progression and 25 week 27 May 1929 5/12/11 week :: x/2-2.5x/2-2.5x 3 Sept 1929 Terminal Blow-off to a 13 Nov Initial Crash Nadir

From the 20 Feb 1928 nadir to the 13 Nov 1929 initial crash nadir the DJIA and SPX self-assembled in a 26/66 week :: x/2-2.5x 1st and second fractal series part of a 3 phase x/2-2.5x/2-2.5x :: 26/66/58 week 3-phase fractal series. Three weekly fractal series make up the 66 week 2nd fractal: a 4-phase 3/7/7/3 or 18 week series, a 5/12/10 week or 25 week series ending 27 May 1929 and a 27 May 1929 3 phase 25 week, 5/12/11 week fractal series with 2 weeks of the 2nd 12 week fractal shared with the 3rd 11 week fractal. The 12 week 2nd fractal is composed of of a 2/5/5/3 week series and the terminal 11 weeks series is composed of a 2/4/5/3 week series.

The daily fractal pattern shown above is highlighted in the below bold italicized type in the terminal 25 week 3-phase 5/12/11 (2 shared) 27 May 1929 fractal series pattern: 5//12 =(2/5/5/3)//11 =(2/4/5/3). The 1st bolded italicized 5/3 week fractal pattern is composed of 2 fractal subseries: a 10 day 2/4/4/3 day 4-phase fractal series pattern and a 3-phase fractal series of 5-/10/9 for a total of 31 days. (In 1929 US equities traded 6 days a week). The 3rd 9 day fractal contained the 3 Sept 1929 peak valuation occurring on day 4 of the 9 day 3rd fractal. This terminal 9 day 3rd fractal is shared as a 9 day 1st decay fractal of a 9/19/16/12 day :: x/2.5x/2x’/1.5x’ 4-phase fractal series ending with the crash low on 13 Nov 1929. In this 4 phase series, the ideal base x’ is 8 days.

The 7 April 2025 to Oct 2026 17/35/28-29 week :: x/2-2.5x/2-2.5x’ Fractal Progression and the 30 March 2026 to 15-23 Oct 2026 28-29 week :: 6/13/12-13 week :: 27/58/56-62 day :: x/2-2.5x/2-2.5x Fractal Progression Terminal Blow-off and initial October 2026 Crash Nadir.

Like the 1928 and 1929 terminal highest equity valuations in the 1807 36/90 year 1st and 2nd multiyear fractal progression, 2025 and 2026 represent the terminal highest equity valuations in the multiyear 1982 13/33 year :: x/2.5x fractal progression.

The Buffet indicator chart of composite equity value to GDP is at all time time follows the same 13/33 year :: x/2.5x fractal growth progression.

On a weekly fractal basis the SPX is following a 17/35/30-31 week :: x/2-2.5x/2-2.5x’ terminal growth and crash sequence. Individual weekly subfractal series self-assembly is shown above. Just as the 1929 crash from its 3 Sept 1929 peak occurred in a 4-phase 2/4/5/3 week fractal series fashion, the initial fractal crash series from its 13-14 Aug 2026 appears to be a 2/5/4-5/3 week self-similar fractal series.

On a daily basis from 30 March 2026, the SPX is following a 27/58/54-60 day :: x/2-2.5x/2-2.5x. with a gapped blow-off between 5 and 6 May days 26 and 27 of the 27 day 1st fractal. The 56-62 day 2nd fractal series is composed of a 10/25/25 day :: x/2.5x/2.5x 3 phase fractal series with an under lying curvilinear slope line. The 56-62 day 3rd fractal begins with a 3/8/8 day fractal series with the 13-14 Aug 2026 , the SPX peak valuation on day 3-4 of the 8 day 3rd fractal self-similar to the 3 Sept 1929 peak on day 4 of the 9 day 3rd fractal of the 5-/10/9 day 3-phase final blow-off. The 8 day 3rd fractal containing the peak valuation then becomes an 8 day 1st fractal decay base for a 4-phase 8/17-20/14-16/11-12 day :: x/2-2.5x/2-2.5x or 2-2.5x’/1.5x or 1.5x’ crash fractal decay series; exactly self-similar to the 1929 9/19/16/12 day :: x/2-2.5x/2x/1.5x crash fractal decay series ending on 13 November 1929. The expected 2020 October Initial Crash Nadir is in the 56-62 day 3rd fractal window, or 15-23 October 2026.

Political considerations: Who will own the 2026 Great October initial Crash?

It is the opinion of this author that without presidential involvement, the final peak valuations for the SPX/DJIA would have been higher, but that the timing of the end of the initial October 2026 crash would have been the same. The synergistic effect of the Iranian oil (et. al. important supply assets) shock (and trade policies) will result in an initial lower October 2026 global equity composite crash nadir valuation.

1929 and 2026 Self-Organizing Fractal Self-Similarities: The US Mid- Midlate October 2026 Initial Crash Nadir

If 1929 and 2026 weekly and daily fractal growth and decay self-similarities hold true, the 2026 initial great crash nadir will occur in mid-midlate Oct 2026.

In 2026 the US economic GDP growth is being propelled by an anticipated 2.6 trillion dollars of global credit expansion and debt accumulation on AI software, hardware, and data centers. This credit expansion has been responsible for 60-90% of 2026 GDP growth.

The real consumer US economy propelled by governmental deficit spending is in dire straights and pushing on a long thready string. Compare the ratio of average annual US %GDP growth to average annual governmental GDP% deficit spending during the following periods:
1940-45: WW2, 1945-1980: post war industrial boom, 1980 to 2000: deregulation and tech boom, 2000-2009: housing boom and crash, 2009-2025: post great recession and covid QE, and 2025-2026 private credit AI and data center bubble.

….. …….. …… Average Annual %GDP Growth
….. ….. ….. ….. …. (%) to annual
….. ….. ….. ….. ….. Deficit Spending …. …. Ratio
1940–1945 : … 1 2.1% to 14.5% …. …. 0.83 : 1
1945–1980 : … 3.2% to 1.1% …. …. … .. 2.91 : 1
1980–2000: … 3.2% to 2.7% … …. … … 1.19 : 1
2000–2009: … 1.8% to 3.2% …. …. … … 0.56 : 1
2009–2025 … . 2.1% to 6.5% …. …… … . 0.32 : 1
2025-2026:
excluding
private AI
bubble growth: … 0.3-0.5% to 6% …. .. 0.05 to 0.08:1

With US deficit at historical high peace time levels, GDP growth in 2025 and 2026 excluding bubble AI credit expansion is likely less than a .08% ratio, and 1/35 to 1/55 of the post WW2 war boom GDP growth to GDP deficit spending ratio.

Had the Iran war and trade wars not intervened, blow-off valuations for equities and in particular AI-related stocks would have been much higher, but the timing of the fractal nadir would have likely been the same. With inflation driven by tariffs and high energy costs, the 10 year Note and 30 year Bond increasing interest rates have put a damper on the equity blow-off and further private investment. Trailing yields on US ten year notes have been negative for the last 24 months for the first time in 223 years (with the exception of one month in 1959.
