Managing Retirement Risks: Longevity, Markets, and Spending Shocks
We were pleased to feature Dr. Wade Pfau, PhD, CFA, RICP®, Professor of Practice at The American College of Financial Services and one of the leading academic voices in
retirement income research, in a recent Knowledge Hub+ (KH+) presentation.
In this discussion, I had the opportunity to interview Dr. Pfau as part of our Master of Science in Financial Planning (MSFP) program,
where we examined the structural risks retirees face — particularly:
• Longevity risk
• Market sequence risk
• Inflation-adjusted spending
• Portfolio sustainability under varying withdrawal rates
Dr. Pfau's research has significantly shaped the profession's understanding of retirement income, including deeper analysis of the so-called "4% rule."
As discussed in the session, the original research identified an initial withdrawal rate — not a fixed percentage indefinitely —
and sustainability depends heavily on sequence of returns, inflation adjustments, and spending flexibility.
Using historical data and practical modeling frameworks, Wade explored how early-market performance and disciplined withdrawal structures materially influence retirement outcomes.
This KH+ presentation reflects the analytical depth emphasized in both:
• The Master of Science in Financial Planning (MSFP) program
• The Retirement Income Certified Professional® (RICP®) program
Retirement income planning is not simply an extension of accumulation strategy. It requires dedicated modeling, risk awareness, and thoughtful implementation. https://www.raymondjamesconnect.com/aIldbt
