INSIGHT

Pre-Retirement Returns Drive Retirement Success

  • Returns in the five to ten years before retirement can matter more than returns after retirement for your long-term success.
  • Research calls this the fragile decade: 10 years before and 10 years after retirement show outsized impact on whether you can actually retire as planned.
INSIGHT

Lost Decade Can Stop Retirement Even With Modest Required Returns

  • The impact of returns after retirement diminishes rapidly, especially in the first five years, but pre-retirement shortfalls can prevent ever reaching the retirement date.
  • A zero-return five-year lead-in (or a 'lost decade') can block retirement even when required returns seem modest.
ADVICE

Check Target Date Fund Risk Before Retirement

  • Don't assume target date funds automatically reduce risk enough in the fragile decade; check their equity exposure and stress-test them.
  • Example: Vanguard 2030 fund held ~60% equities and would still fall ~43% in a 2008-style crash.
