The planned change in asset allocation over time, typically shifting from stocks to bonds as you approach or enter retirement.

What Is Glide Path?

A glide path is the predetermined schedule for changing your portfolio's asset allocation over time, usually shifting from aggressive (more stocks) to conservative (more bonds) as you approach retirement.

Building Your Glide Path:

Factors to Consider:

  1. Risk tolerance
  2. Other income sources (Social Security, pension)
  3. Retirement timeline
  4. Health and longevity expectations
  5. Spending flexibility

Simple Rule of Thumb: Stock allocation = 120 - your age (or 110 for more conservative)

Customizing Your Glide Path:

  • More pension/SS income → Can hold more stocks
  • High risk tolerance → Slower equity reduction
  • Early retirement → May need more growth longer
