A target date fund's glide path is a critical component that determines how aggressively the fund invests in stocks versus bonds as it approaches its target retirement date. The glide path is a schedule that outlines the fund's asset allocation over time.
The typical glide path is a gradual shift from a more aggressive stock-heavy allocation to a more conservative bond-heavy allocation. This shift usually starts around 20-25 years before the target retirement date and continues until the fund reaches its target date.
Investors can expect the fund to become more conservative as it approaches the target date, with a greater emphasis on preserving capital rather than growing wealth.

What are Target Date Funds?
Target Date Funds are a type of investment that adjusts its mix of stocks and bonds over time to help you reach your retirement goal.
To learn more about investing concepts and investing through your plan, you can visit a resource center for more information.
A Target Date Fund's investment mix gradually becomes more conservative as it approaches your target retirement date, a process known as the glide path.
Think of the glide path like an airplane touching down on a runway - the closer the airplane gets to the landing strip, the more conservative your investment mix gets.

Understanding Glide Paths
Vanguard Target Retirement Funds and Trusts reach a 30% equity allocation via a Target Retirement Income Fund or Trust.
The glide path is designed to evolve as the investors' risk profiles change over time. Each vintage assumes a retirement age of 65.
Participants can maintain a 50% equity allocation by switching to Vanguard Target Retirement Income and Growth Trust.
Target date allocations are designed to change over time. The Principal LifeTime Strategic Index does not include exposure to real assets/other category.
Investment risk always remains, and neither the principal nor the underlying assets of the target date allocations are guaranteed.

Participant Behavior and 'To' vs. 'Through'
Participant behavior and the type of glide path used in a defined contribution (DC) plan can have a significant impact on retirement outcomes.
Participants who plan to annuitize once they hit retirement may benefit from a "to" glide path.
However, "through" glide paths have seen more popularity due to the rising number of retirees keeping assets in their DC plans post-retirement.

Equities and Investment Strategy
The equity weighting across the glide path is one of the most important determinants of TDF outcomes, as it characterizes the trade-off between growth and safety throughout the portfolio's life cycle.
A higher equity weighting can lead to greater-than-necessary risk exposure due to the higher volatility profile that equities have relative to fixed income securities.
Some TDFs allocate more heavily toward risky assets, such as equity securities, in the early years of the glide path, with equity starting points of 95% or higher.
Our own TDF has a 90% equity starting point, which is lower than some of our competitors but still allows for growth over time.
A higher equity weighting can enhance a TDF's ability to grow wealth over time, but it also increases the risk exposure.
The industry tends to allocate more heavily toward equities in the early years of the glide path, but it's essential to strike a balance between growth and safety.
Continuous evaluation of the equity weighting is crucial, as seen in our annual glide-path revalidations, which emphasize the importance of this topic.

Many Plans Offer Funding
Many plans offer target date funds (TDFs), which are designed to make it easier for participants to know what to select for their assets.
A popular choice for retirement savers, TDFs have a fund with the year closest to their retirement date in its name, suggesting that the fund is being managed for investors who plan to retire in or near that year.
Some TDFs are set up to take the investor to retirement, while others are managed to take you through it.
TDFs that take you to retirement reach their most conservative when the target date occurs and their asset allocations don't generally change after that.
In contrast, TDFs that take you through retirement continue to change their asset allocations, reaching their most conservative later in retirement.
