Comprehensive Institutional Breakdown
When an investor is decumulating (withdrawing cash for living expenses), experiencing market crashes (such as 1929, 1973, or 2008) in the first 3 to 5 years forces liquidations of depressed shares. Because depleted shares can never participate in the subsequent recovery, the portfolio runs out of money decades prematurely, even if long-term average returns appear adequate.
Carl Brent Anthony Institutional Rule
Insulate decumulation with 24–36 months of short-term liquid cash reserves to avoid selling depressed equities during cyclical drawdowns.
Algorithmic Formula / Notation
W_{t+1} = [W_t - Withdrawal_t] × (1 + R_t); Negative R_t early permanently degrades terminal capital W_T.
Institutional Scenario Example
Two retirees with identical 7% average returns: Retiree A experiences -15% in years 1-2 and exhausts funds by age 78; Retiree B experiences -15% in years 25-26 and dies with millions.
