Boom Retirement Readiness & Sequence Risk Lab
Stock market rallies and artificial intelligence excitement have inflated 401(k) and brokerage accounts, tempting workers 55 and older to exit early. But selling assets during the first five years of retirement after a peak introduces fatal sequence-of-returns risk. Test if your nest egg can survive historically devastating market regimes.

The Psychology & Math of the "AI Boom" Retirement Wave
When equity markets skyrocket, retirement accounts swell to all-time highs. Workers 55+ see paper wealth that easily satisfies the textbook "4% rule" based on the current balance.
However, William Bengen's foundational 4% safe withdrawal research and the Trinity Study revealed that retirees who quit at the absolute crescendo of a secular bull market suffer disproportionately. When early negative returns collide with mandatory liquidations to fund living expenses, the principal gets irreversibly decimated—a phenomenon known as Sequence-of-Returns Risk (SRR).
Essential Stress Mitigations
Why is a 4% rule dangerous right after a historic rally?
The 4% rule assumes you start at average market valuations. Starting at historic cyclically adjusted price-to-earnings (CAPE) peaks historically drops the safe initial withdrawal rate to 3.25% - 3.5% unless you have flexible spending or a cash buffer.
The Cash Cushion & Bond Tent Strategy
Holding 2 to 3 years of living expenses in short-term Treasuries, CDs, or high-yield money market funds allows a new retiree to avoid selling equities at a 30% discount during years 1 through 3 of a sudden market collapse.
Guyton-Klinger Spending Guardrails
Instead of blindly indexing withdrawals upward for inflation every year, guardrails mandate a 10% trim in your discretionary budget if your current withdrawal rate rises more than 20% above your initial target rate due to portfolio declines.
Bridging the Gap to Age 67 Social Security
Retiring at 57 means a 10-year period where your portfolio must shoulder 100% of your living expenses before Social Security starts. This front-loads liquidation pressures into the exact window where market volatility is most lethal.
