Architect 2.2: Great Depression Anchor and Rolling Anchor Tests

DJI rolling-anchor Fibonacci study: 1932 through the modern era

HP Fib AI Structural Series Post 2.2 Asset: DJI Weekly Range: 1932–Present

Method: Each major market correction is used as a fresh Fibonacci anchor. The same 1.272 / 1.618 / 2.20 / 2.618 / 3.60 / 4.236 / 6.80 extension ladder is then tested against the subsequent cycle. When a cycle reaches the 6.80 region or beyond and then rolls over, or produces a confirmed 4.236 retest, that swing becomes the primary input for the next anchor. This produces a rolling, repeatable cross-era test of the framework across different compositions, regulatory regimes, and volatility conditions.

Context note: the previous post established the DJI inception swing from 1896. This post continues from where that sequence concluded — the 1929–1933 Depression — and tracks each subsequent major cyclic anchor through to current structure. By the time this series reaches post-2000 anchors, the moves described had generally-accepted news catalysts and were widely considered unpredictable in real-time. The data is presented without narrative adjustment.

Anchor 1: Great Depression Expansion Cycle (1932–1987)

Symbol:
Dow Jones Industrial Average (DJI), Weekly
Anchor High:
385.00 (1929 Peak)
Anchor Low:
42.92 (July 1932)
Range:
342.08 points — extension levels derived from this swing

Following the 1932 low, the DJI began a multi-decade recovery phase. The Fibonacci extension ladder derived from the 1929 high and 1932 low governed structurally significant price interactions for the following 55 years.

DJI Great Depression anchor swing: 1929 high 385 and 1932 low 42.92 with Fibonacci extension levels derived
Overview: The 1929–1932 anchor swing defines the Fibonacci extension ladder governing DJI price structure through to 1987.

Phase 1: Initial Expansion and the 1.272 Reaction (1955)

The post-war recovery produced a largely uninterrupted rally from the 1932 low. The first structurally meaningful interaction with the extension grid occurred at the 1.272 level.

DJI reaction at the 1.272 Fibonacci expansion level in September 1955
September 1955: Price tags the 1.272 extension (approx. 477), producing the first notable weekly reaction and consolidation in the post-war era. The approach was largely uninterrupted from the 1942 low.
  1. September 1955: 1.272 extension (approx. 477) tagged. First notable weekly reaction occurs here after an uninterrupted post-war advance.

Phase 2: The 1.618 Stall and Multi-Year Consolidation (1959–1963)

The 1.618 extension acted as a structural ceiling across a four-year period, transitioning the market from a straightforward recovery phase into a structured range.

DJI reaching the 1.618 Fibonacci extension in April 1959 at approximately 596
April 1959: Price reaches the 1.618 extension (approx. 596). General upside drift continues but the level initiates a multi-year stall characteristic of this tier.
DJI sideways range around the 1.618 Fibonacci level in the early 1960s
Early 1960s: Continued oscillation around the 1.618 level. The stall here is consistent with the 1.618 acting as a trend gate in prior and subsequent cycles.
DJI decisively breaking above the 1.618 Fibonacci level in October 1963
October 1963: The 1.618 level is decisively cleared on a weekly close basis, initiating a smooth directional rally toward the next major structural tier.
  1. April 1959: 1.618 extension (approx. 596) reached. Pronounced stall begins.
  2. 1959–1963: Multi-year oscillation around the 1.618 level.
  3. October 1963: 1.618 decisively broken on weekly basis. Rally toward the 2.618 begins.

Phase 3: The 17-Year Range — 2.20 to 2.618 (1965–1982)

This period represents the most structurally defined phase of the Great Depression anchor. For approximately 17 years, the DJI remained contained within the 2.20 and 2.618 extension levels, with the ceiling failing repeatedly before a decisive break.

DJI reaching the 2.618 Fibonacci extension at approximately 938 in November 1965
November 1965: Price reaches the 2.618 extension (approx. 938) for the first time, beginning the 17-year structural range.
DJI September 1966 corrective low near the 2.20 Fibonacci expansion
September 1966: A sharp correction from the 2.618 ceiling finds a weekly low close to the 2.20 expansion (approx. 795). The 2.20 acts as structural floor.
DJI October 1968 retest of the 2.618 Fibonacci ceiling without sustained breakout
October 1968: Price retests the 2.618 ceiling (approx. 938), failing again to sustain a breakout above the level.
DJI June 1970 liquidity crash finding support at the 1.618 Fibonacci expansion level
June 1970: A liquidity event produces a sharp crash move that finds support at the 1.618 level (approx. 596) — the same level that previously capped the market from 1959–1963.
DJI September 1972 retest of the 2.618 level with a brief overshoot before a 40% decline
September 1972: Price hits the 2.618 ceiling again with a brief overshoot, followed by a crash move of approximately 40%.
DJI November 1974 generational low reversing near the 1.618 Fibonacci expansion
November 1974: The crash move terminates precisely at the 1.618 level (approx. 596). This marks the secular low of the decade; the same level provided support in 1970 and again here, bookending a 4-year range.
DJI 1976–1980 range oscillation between the 2.20 and 2.618 Fibonacci levels
1976–1980: Recovery from the 1974 low returns to the 2.618 range. Oscillation between the 2.20 floor and 2.618 ceiling resumes.
DJI May 1982 final low of the 17-year range holding on the 2.20 Fibonacci expansion
1980–1982: Range chop continues. The final low of the 17-year structure holds on the 2.20 level in May 1982, completing the range-defined phase.
  1. November 1965: 2.618 extension (approx. 938) hit for the first time.
  2. September 1966: Sharp correction to a low close to the 2.20 expansion (approx. 795).
  3. October 1968: Retest of the 2.618 ceiling; breakout fails to hold.
  4. June 1970: Liquidity crash finds support at the 1.618 level (approx. 596).
  5. September 1972: 2.618 ceiling tagged again with brief overshoot; 40% decline follows.
  6. November 1974: Crash low terminates at the 1.618 level — generational low.
  7. 1976–1982: Range oscillation resumes between 2.20 and 2.618.
  8. May 1982: Final range low holds on the 2.20 level.

From November 1965 through May 1982 the DJI spent approximately 17 years in a range almost entirely bounded by the 2.20 and 2.618 levels, with the 2.618 as a ceiling that repeatedly failed and the 2.20 as the recurrent structural low. Two crash events during this period reached the 1.618 level rather than the 2.20. The final range low in May 1982 held precisely on the 2.20. This mirrors the 14-year 0.76–1.61 range observed in the original inception swing cycle, one structural tier higher.

Phase 4: Parabolic Expansion Through the 6.80 to the 1987 High (1982–1987)

The break of the 17-year 2.618 ceiling in October 1982 produced an immediate and sustained acceleration characteristic of over-performance phases identified across prior anchor cycles.

DJI October 1982 decisive breakout above the 2.618 Fibonacci level at 938, initiating trend acceleration
October 1982: The 2.618 level (approx. 938) is decisively cleared. Per the model's pattern across prior cycles, this triggers an immediate acceleration phase.
DJI 1983 reaching the 3.60 Fibonacci extension at approximately 1274
1983: Price reaches the 3.60 extension (approx. 1,274). A brief stall occurs before momentum carries the market through.
DJI clearing the 4.236 Fibonacci level at approximately 1492 with minimal resistance in parabolic regime
Mid-1980s: Price clears the 4.236 level (approx. 1,492) with essentially no resistance, confirming the parabolic regime that characterises cycles at this stage.
DJI 1987 cycle high in the region of the 6.80 Fibonacci extension near 2368
Spring 1987: price reaches the 6.80 extension (approx. 2,368). The 6.80 is not where the cycle ended — price carried about 15% further to the August 1987 peak near 2,722, which sits around the 7.8× extension of this anchor. This is the pattern across the series: cycles reach the 6.80 as a minimum and typically run beyond it before turning.
DJI October 1987 Black Monday crash low occurring near the 4.236 Fibonacci retest level
October 1987: The "Black Monday" crash low occurs just ahead of a full retest of the 4.236 level (approx. 1,492). This completes the ending sequence of the Great Depression anchor cycle: 6.80-region high → crash → 4.236 retest.
  1. October 1982: 2.618 level (approx. 938) decisively broken; acceleration follows immediately.
  2. 1983: 3.60 extension (approx. 1,274) reached; brief stall then through.
  3. Mid-1980s: 4.236 level (approx. 1,492) cleared with no meaningful resistance.
  4. Spring 1987: 6.80 extension (approx. 2,368) reached; price overshoots to the August peak near 2,722 before the crash.
  5. October 1987: "Black Monday" crash terminates near a full retest of the 4.236 level.

The 1987 crash was attributed in contemporaneous analysis to computerised program trading. Structurally, the peak was derivable from the 1932 anchor 50 years prior, and the crash low aligned with the 4.236 retest, echoing the ending sequences seen in prior cycles. The 1987 swing (August high to October low) now becomes the primary input for the next anchor cycle.

Anchor 2: The 1987 Crash Cycle (1987–2007)

1987 anchor definition: high 2,722.42 and crash low 1,738.74. Fibonacci extensions are projected from this 983-point swing as the primary unit of measure for the subsequent cycle.

Phase 1: The 1.272 and 1.618 Phases (1990–1994)

DJI approaching the 1.272 Fibonacci extension from the 1987 anchor in mid-1990
Mid-1990: Price approaches the 1.272 extension (approx. 2,989). The recovery from the 1987 low has been orderly, consistent with prior cycle behaviour at this stage.
DJI July 1990 sharp weekly correction at the 1.272 Fibonacci extension level at 2989
July 1990: Price tags the 1.272 extension (approx. 2,989), producing a sharp weekly correction consistent with prior 1.272 interactions in this series. The Gulf War period.
DJI multi-year consolidation at the 2.20 Fibonacci level at 3330 in the early 1990s
Early 1990s: Multi-year consolidation at the 2.20 expansion (approx. 3,330). The market stalls here for an extended period before a decisive break, replicating the 1959–1963 pattern one anchor higher.
DJI definitive weekly break above the 1.618 Fibonacci level signalling transition to the next expansion tier
Late 1993 / early 1994: Definitive weekly break above the 1.618 level. Per the model, this signals transition into the next structural tier.
  1. July 1990: 1.272 extension (approx. 2,989) reached; sharp weekly correction consistent with prior 1.272 interactions.
  2. January 1991: Correction low near 0.76 level (approx. 2,487).
  3. Early 1990s: 2.20 expansion (approx. 3,330) reached; multi-year consolidation phase begins.
  4. Late 1993: Definitive break above the 1.618 level.

Phase 3: Mid-Cycle Expansion and the 2.618 Break (1995–1997)

DJI decisive breakout above the 2.618 Fibonacci level at 4314 in 1995-1996 signalling trend acceleration
1995–1996: Clean breakout above the 2.618 ceiling (approx. 4,314). Per the model's precedent, a decisive 2.618 break initiates the over-performance phase of the cycle.
  1. 1995: 2.20 level (approx. 3,902) cleared without significant hesitation.
  2. 1995: 2.618 extension (approx. 4,314) reached.
  3. 1995–1996: Decisive break above the 2.618 ceiling; over-performance phase begins.

Phase 4: Parabolic Acceleration to the 4.236 (1997–2000)

The late 1990s Dot-com era contains the parabolic acceleration characteristic of 4.236 expansion targets in prior cycles.

DJI reaching the 4.236 Fibonacci extension at approximately 5906 during the late 1990s bull market
Late 1990s: The DJI reaches the 4.236 extension (approx. 5,906). Note: the index subsequently extended significantly beyond this level as the Nasdaq bubble inflated, but the 1987-anchor 4.236 remained a structural reference point throughout that period.

  1. Late 1996: 4.236 extension (approx. 5,906) initially reached. The Federal Reserve chairman uses the phrase "irrational exuberance" this same month.
  2. 1998: Asian Contagion correction. The 4.236 level acts as a structural pivot during this event.
  3. End of 1999 / early 2000: The index extends significantly above the 1987-anchor 4.236 as the Nasdaq bubble peaks.
  4. 2000–2003: Dot-com bust. The correction navigates near the 1987-anchor 4.236 before a recovery.
  5. February 2009: The 1987-anchor 4.236 is retested at the GFC crash low. This completes the ending sequence for the 1987 cycle.

The 1987 anchor cycle is the first in this series where the 6.80 level was substantially exceeded and the final crash low did not produce a clean 4.236 retest in a single move. However, the primary extension levels continued to function as structural reference points throughout, and the broad pattern — 1.272 reaction, 1.618 consolidation, 2.618 over-performance trigger, 4.236 area as late-cycle pivot — remained consistent with the model. With the GFC swing providing a confirmed major correction, the 2007–2009 high-to-low becomes the next anchor.

Anchor 3: The GFC Anchor Cycle (2007–Present)

Symbol:
DJI Weekly
Anchor High:
14,165 (October 2007)
Anchor Low:
6,547 (March 2009)
Range:
7,618 points

The GFC swing represents one of the most structurally significant anchor inputs in modern market history. The following sequence documents the expansion of the DJI from the 2009 low against the Fibonacci extension ladder derived from the 2007–2009 collapse.

DJI GFC anchor swing definition: 14165 high to 6547 low with extension levels
GFC anchor: high 14,165 (October 2007) and low 6,547 (March 2009). Extension levels project the expansion framework for the subsequent cycle.

Phase 1: Reclaiming the 1.0 and 1.272 Extension (2013)

Per prior anchor cycles, the reclaim of the anchor's 1.0 level (the prior swing high) initiates the expansion ladder.

DJI reclaiming the 2007 high in 2013 and extending toward the 1.272 Fibonacci target
2013: The DJI reclaims the 1.0 level at the 2007 high and extends toward the 1.272 target near 16,221. This marks the formal transition from anchor recovery to expansion-phase continuation.
  1. 2013: DJI reclaims the 1.0 level (14,165). Breakout immediately targets the 1.272 extension (approx. 16,221), consistent with model norms.

Phase 2: The 1.618 Consolidation (2014–2016)

DJI consolidating at the 1.618 Fibonacci expansion at 18872 in 2015-2016 with multiple tests
2014–2016: The 1.618 extension (approx. 18,872) acts as resistance and then support across multiple tests. This level will later serve as the primary support floor during the 2020 crash.
  1. 2014–2015: 1.618 extension (approx. 18,872) reached; approximately 18-month sideways consolidation begins.
  2. August 2015: 1.618 retested and holds as support.
  3. January 2016: 1.618 retested a second time; clean hold. The subsequent rally from this level is notably sustained.
  4. November 2016: 1.618 definitively broken to the upside.

Phase 3: The 2.20 to 2.618 Decision Phase (2017–2020)

DJI 2017 clearing the 2.20 level at 23306 and reaching the 2.618 decision level at 26490
2017: Price clears the 2.20 level (approx. 23,306) and reaches the 2.618 "Decision" level (approx. 26,490).
DJI 2018-2020 broadening formation and volatility around the 2.618 Fibonacci level including Volmageddon
2018–2020: Significant volatility around the 2.618 level (approx. 26,490), including the Volmageddon event (February 2018). A multi-year broadening formation develops around this structural decision zone.
DJI 2019 decline stopping just under the 2.20 Fibonacci extension at 23306
2019: The Q4 2019 decline stops just under the 2.20 extension (approx. 23,306). The subsequent COVID-19 crash would break decisively below this level to retest the 1.618 floor.
  1. 2017–2018: Price clears the 2.20 (approx. 23,306) and reaches the 2.618 Decision level (approx. 26,490). A multi-year broadening formation and elevated volatility follows.
  2. January–December 2018: Correction from the 2.618 ceiling to the 2.20 floor. The Volmageddon event (February 2018) occurs within this range.
  3. 2019: Q4 2019 decline stops just under the 2.20 extension (approx. 23,306).
  4. October 2020: 2.618 reclaimed and retested as support; the second break is validated, initiating the over-performance phase.

The 2018–2019 broadening formation at the 2.618 level, including the Volmageddon event (February 2018), can be read as an extended 2.618 decision zone. The Q4 2019 decline stops just under the 2.20 extension (approx. 23,306), maintaining structural integrity before the COVID-19 crash broke decisively through the 2.20 and retested the 1.618 floor (approx. 18,872).

Phase 4: Acceleration Through the 3.60 and 4.236, Toward the 6.80 (2021–Present)

DJI March 2020 COVID crash finding support just above the 1.618 Fibonacci extension at 18872
March 2020: The COVID-19 crash low finds support just above the 1.618 extension (approx. 18,872), validating this level's structural significance established during the 2014–2016 consolidation. The Federal Reserve announces unlimited quantitative easing at this inflection point.
DJI oscillating around the 3.60 Fibonacci level using it as a base for the next expansion leg
2022: Price action oscillates around the 3.60 level, establishing it as a structural base for the next expansion leg.
DJI continued oscillation around the 3.60 Fibonacci level as support in 2022-2023
2022–2023: Continued use of the 3.60 level (approx. 33,970) as structural support across multiple weekly tests before the move up through the 4.236.
DJI reaching and clearing the 4.236 Fibonacci expansion near 38815
The 4.236 extension (approx. 38,815) was reached in late 2023 and then cleared. As of mid-2026 the DJI trades near 53,300 — roughly 37% above the 4.236. The 4.236 was not a cycle end here; price continued well past it into the higher rungs of the ladder, which is the expected progression once 4.236 is cleared. (Note the 4.236's other role in this cycle: the 2009 crash low itself sat at a 4.236 downside extension of the preceding 2007–08 topping swing.)
  1. 2021: Price clears the 3.20 (approx. 30,923) and reaches the 3.60 extension (approx. 33,970).
  2. 2022–2023: 3.60 level (approx. 33,970) acts as repeated weekly support during mid-cycle consolidation.
  3. December 2023: 4.236 extension (approx. 38,815) reached.
  4. 2024–2025: 4.236 cleared; price continues higher rather than turning here.
  5. Mid-2026: DJI near 53,300 — about 37% above the 4.236 and roughly 9% below the 6.80 extension (approx. 58,350).

Longitudinal note: the GFC anchor shows the same ladder levels acting as structural reference points. The 1.618 level (approx. 18,872) acted as the 2020 crash floor. The 3.60 (approx. 33,970) acted as the 2022–2023 mid-cycle pivot. The 4.236 (approx. 38,815) was reached and then cleared. It is worth being precise about what the 4.236 is and is not: in none of the three cycles is it the level at which the expansion ended. Measured against each anchor's own range, the 1929/1932 cycle topped in 1987 around the 7.8× extension; the 1987 cycle topped in 2000 around the 10× extension; and the GFC cycle has, so far, carried past its 4.236 and is extending into the upper ladder. Every completed cycle in this series reaches at least the 6.80 and then runs further. The 4.236 is a waypoint — a level expansions pass through, sometimes pausing at — not a terminal.

Cross-Cycle Summary

Recurring structural pattern across all three anchors:

  • The 1.272 level produces the first notable corrective weekly reaction after the initial recovery from a crash low.
  • The 1.618 level acts as a multi-year consolidation gate; the market stalls here for an extended period before a decisive break, after which the next major tier is targeted.
  • The 2.20–2.618 band functions as a decision range; oscillation within this band, with the 2.618 repeatedly failing, precedes an over-performance trigger.
  • Once the 2.618 is cleared on a weekly basis, a high-momentum acceleration phase toward the 4.236 follows with minimal structural resistance.
  • The 4.236 is a waypoint, not a cycle end: in this series every expansion clears it and continues. Once it is cleared, a parabolic move toward the 6.80 tends to follow, and the cycle high has consistently landed beyond the 6.80 — near the 7.8× extension in 1987 and near the 10× extension in 2000. The 6.80 is best read as a level every cycle reaches at minimum, not as an upper bound.
  • The 1.618 from the current cycle tends to act as major structural support during crash events that occur within the expansion phase (e.g., 1970 and 1974 crashes at Depression-anchor 1.618; 2020 COVID crash at GFC-anchor 1.618).
