Post-Decline Deployment

Objective — deploy borrowed capital into equities after a significant decline rather than before one, on a rule written in advance.

Risk level — 3 — High risk. Risk justification — it increases net market exposure, which is level 2 at minimum under SCHEMA §2.2’s assignment rule, and it adds the timing-judgement test: the benefit depends on identifying a decline deep enough to deploy into, which is a judgement the evidence does not support most people making reliably. Held at 3 for consistency with buy-more-low, which is the tranched form of the same decision. Benefit justification — unverified — needs Talbot. Jurisdiction — Canada for tax treatment. U.S. applicability unverified. Decline type — A, C and D. Type B is adverse, not merely weaker: 2022 delivered a worse entry and rising carry at the same time, so the borrowing cost rose exactly as the opportunity appeared.

Prerequisites

Four, and the source treats all four as binding rather than advisory:

A non-callable facility — non-callable-first. A callable one is on the source’s Harmful list.
Capacity arranged in advance — standby-credit-capacity. Lenders are least willing at the moment the rule fires.
A written rule, made when calm. Which thresholds, which accounts, which amounts, which order.
An expense buffer held separately. “The expense buffer is what makes Buy More Low possible. An investor who must sell equities to eat during a decline cannot also be buying. It is infrastructure, not drag.”

Mechanism

The premise, as the source finally states it:

Adding leverage after a significant decline is almost always lower-risk than adding the same leverage before it. Whether the resulting risk is low enough, and whether remaining risks can be managed responsibly, is a separate and harder question.

Conflating those two is how responsible leverage guidance gets misread as promotion, and this record keeps them apart.

Ordering matters, and it is not optional. The source’s sequencing principle:

Cash restores the target allocation. Leverage exceeds it.

Deploying cash costs only the opportunity return on cash, which is already being paid daily. Borrowing costs the after-tax interest rate ongoing, plus a liability, facility risk, servicing obligations and a magnified drawdown. So cash goes first, and borrowing while holding idle cash means paying to rent money you already have. The only exception is cash carrying a tax toll to access — and even then, the source says plan the extraction ahead of the trigger rather than borrow around it.

What the thresholds are worth knowing about. Across 16 bear markets 1929–2026, S&P 500 closing price index:

Depth	Frequency	P(reaches, given a −20% hit)
−20%	1 per 6.5 yrs	100%
−25%	1 per 8.1 yrs	80%
−30%	1 per 12.1 yrs	53%
−40%	1 per 19.4 yrs	33%
−50%	1 per 32.3 yrs	20%

⚠ Those are S&P 500 price-index numbers. The source’s own standing rule is that the trigger index is the investor’s domestic index (TSX for Canadians) and outcome analysis must be total return. Recomputation is required before any dollar figures ship.

One structural advantage comes from the instrument rather than the timing. The project tested buying long-dated options at a decline trigger instead, and every configuration excluding March 2020 lost money — 0.18× to 0.38× across strikes and expiries:

The binding constraint is expiry, not skew. A non-callable investment loan deployed at −30% has no expiry, no time decay, no roll, and nothing to lose to the passage of time. For post-drop convexity, the absence of an expiry date is worth more than the convexity itself.

Benefits

Higher expected return than deploying the same leverage at a fixed date, on the source’s premise above.
No carry while waiting, provided the capacity is standby rather than drawn — unlike a cash-hoarding version of the same idea.
No expiry, so being early is survivable in a way an option position is not.

Risks

Wide distribution of outcomes. This is the source’s own summary: higher expected return, wide distribution.
Type B is adverse. 2022 is the case that breaks it, and “any system that doesn’t handle 2022 explicitly will be tested against it by the first sceptical advisor.”
The trigger is not the bottom. In 2001 the index fell from 966 to 777 after the −30% crossing; in 2008 from 1,057 to 677 within five months. A rule that deploys at a threshold will routinely deploy into further decline.
Valuation context matters and is currently hostile. CAPE near 40.6 in September 2026: a 20% drop lands around 32, still above the 1929 peak. 2000–02 was −49% and took roughly a decade to recover nominally.
Loan structure matters more to outcome than entry price — which is why non-callable-first is a prerequisite rather than a companion.

Failure modes

Deploying at a decline that continues, exhausting capacity before the bottom.
Holding cash in order to run this, which converts it into the strategy the evidence rejects. See Counterarguments.
Deploying through a callable facility, which is explicitly Harmful in the source.
Deploying discretionarily rather than on the written rule — the version this record’s tier assumes is the rule-based one.

Costs

After-tax interest for the life of the loan, plus facility setup. unverified — needs Talbot in magnitude.

Tax considerations

Interest on money borrowed to earn income from property is deductible under ITA §20(1)(c) — see claim-investment-interest-deduction. Tracing must be clean from the first draw: interest-tracing-hygiene. Deductibility lowers after-tax carry and is the single largest lever on the cost side, but it does not change the tier.

Who it may suit

An investor with a written rule, a non-callable facility arranged in advance, a separate expense buffer, and the income to service the loan through a period when income itself is under pressure. That is a narrow set, and the source’s own framing is that most should not act.

Who should avoid it

Anyone missing any one of the four prerequisites. They are not a checklist to mostly satisfy.
Anyone who would need to sell to service the loan during the decline.
Anyone holding cash specifically to run this — the evidence is against that version, and it is a different strategy.
Anyone who has not separately justified leverage at all.

Implementation outline

Satisfy all four prerequisites, in order, before any decline.
Write the rule: index, thresholds, amounts, accounts, order, and what happens if a threshold never fires.
Deploy cash to target allocation first; leverage only exceeds target.
Deploy on the threshold, through the non-callable facility, without re-deciding.
Document tracing at the moment of the draw.

Evidence status

documented — stated in market-drop-wins-library-v2 (T3-3) and argued across market-drop-wins-master-log-v2 §3.1–§3.7. Not modelled in sd-math, and the source’s own numbers are S&P-500 price-index figures that require recomputation on a Canadian total-return basis before they can be published as outcomes.

Counterarguments

The buy-the-dip critique, which is the serious one. AQR (2025), across 60+ years and 196 implementations: holding cash to deploy on declines underperformed passive investing in more than 60% of cases, with average alpha around 0.5%/yr — statistically indistinguishable from chance — and 18.7% lower ending wealth than dollar-cost averaging new savings. PWL Capital reached the same conclusion across six country indexes plus MSCI World. The source’s two bounds, and they are narrow: (1) it is an unconditional average, and conditioned on the highest-valuation starting points the case is materially weaker — the source flags this as needing re-testing on the top valuation quintile, and that test has not been run; (2) the critique bites on strategies that cost something while waiting. This record deploys borrowed capacity, which costs nothing undrawn — so the cash-drag mechanism the critique measures does not apply directly. That is a real distinction, not a rebuttal of the finding.
“Leverage after a decline is still leverage.” Conceded in full. The premise says lower-risk than the same leverage taken earlier, not low-risk.

Variants

The source’s working label was post-decline leverage deployment.
buy-more-low is the tranched form of this decision and is SDC’s own named strategy; this record is the general case, deliberately kept separate so the general premise can be cited without adopting a particular tranching rule.
A cash-only version — deploying existing cash rather than borrowing — is a different and much lower-risk strategy, and is where the sequencing principle sends most readers first.

Open questions

Recomputation of every frequency and outcome figure on a Canadian domestic total-return basis. Nothing quantitative ships before this.
The AQR conditional re-test on the top valuation quintile, which the source itself flags as outstanding.
Whether a fully pre-committed threshold rule executed through a non-callable facility is a level 2 strategy rather than level 3 — the timing-judgement test arguably does not apply to a mechanical rule. A level change is a Risks-then-CEO decision under the IP charter and is not made here.
