What Are Target Date Funds?
Target date funds are a type of collective investment scheme, often structured as a mutual fund or collective investment trust, designed to provide a simplified, long-term investment solution for individuals, typically geared towards retirement savings. These funds fall under the broader category of Investment Management and Portfolio Theory, offering a professional approach to managing an investment portfolio over time. A defining characteristic of target date funds is their "glide path," which automatically adjusts the underlying asset allocation as the specified target date approaches. This means the fund typically holds a higher proportion of growth-oriented assets like equities in its early years and gradually shifts towards more conservative investments such as bonds and cash equivalents as the target date draws nearer.
History and Origin
The concept of target date funds was pioneered in the early 1990s by Donald Luskin and Larry Tint of Wells Fargo Investment Advisors (later Barclays Global Investors, BGI). These funds were initially introduced in 1994, with BlackRock's LifePath solutions being among the first to offer this strategy.16 Their widespread adoption significantly accelerated in the United States following the passage of the Pension Protection Act of 2006.15 This legislation facilitated the auto-enrollment of employees into defined contribution plans, creating a demand for Qualified Default Investment Alternatives (QDIAs). Target date funds emerged as a popular choice for QDIAs due to their "set-it-and-forget-it" convenience, making them ideal for plan participants who prefer not to actively manage their retirement savings.14
Key Takeaways
- Target date funds are professionally managed investment portfolios that automatically adjust their asset allocation over time.
- They are designed with a specific future date in mind, usually an investor's anticipated retirement year.
- The fund's "glide path" dictates the gradual shift from more aggressive investments (like stocks) to more conservative ones (like bonds).
- Target date funds aim to simplify retirement planning and are a common default investment in many employer-sponsored retirement plans.
- While offering convenience, it is important for investors to understand the fund's underlying strategy, including its fees and specific glide path.
Interpreting the Target Date Fund
Understanding a target date fund primarily involves examining its stated target year and its "glide path." The target year, often included in the fund's name (e.g., "2040 Fund" or "2050 Fund"), indicates the approximate year the investor expects to retire or begin withdrawing funds. The glide path illustrates how the fund's asset allocation will change from the present until and sometimes beyond the target date. It defines the fund's strategy for managing risk tolerance as an investor ages, aiming to reduce volatility closer to retirement. Investors should compare the fund's specific glide path and final asset allocation to their individual financial situation and comfort level with risk. For instance, some target date funds might maintain a higher equity exposure even at the target date ("through retirement" glide path), while others become most conservative at the target date ("to retirement" glide path).13
Hypothetical Example
Consider an individual, Sarah, who is 30 years old and plans to retire around 2065. She decides to invest in a "Target Date Fund 2065."
Initially, the Target Date Fund 2065 holds a high percentage of equities, perhaps 85% stocks and 15% bonds, aligning with Sarah's long-term investing horizon and capacity for market fluctuations. As Sarah moves through her career, the fund's professional managers will automatically rebalance the portfolio. By the time Sarah is 45 (2040), the fund might have adjusted to 70% stocks and 30% bonds. By 2060, five years before her target retirement, the allocation could be closer to 40% stocks and 60% bonds, significantly reducing exposure to equity market swings. This automatic adjustment means Sarah does not need to manually change her investment mix, providing a hands-off approach to her diversification strategy.
Practical Applications
Target date funds are predominantly used in employer-sponsored retirement plans, such as 401(k)s, where they often serve as the Qualified Default Investment Alternative (QDIA) for participants who do not make an active investment election.11, 12 They simplify investment decisions for individuals by providing a single, professionally managed fund that adapts to their changing life stage. This makes them highly practical for those who prefer a hands-off approach to their retirement savings.
Beyond employer plans, target date funds can also be held in other investment accounts like individual retirement accounts (IRAs) or college savings plans. The Department of Labor (DOL) has issued guidance for fiduciaries of ERISA-covered plans on selecting and monitoring target date funds, emphasizing the importance of understanding the fund's investment strategy, fees, and glide path.10 The Securities and Exchange Commission (SEC) has also proposed rules to enhance disclosures for target date funds, aiming to provide investors with clearer information about their asset allocation over time and highlight that they are not guaranteed investments.8, 9
Limitations and Criticisms
Despite their convenience, target date funds face several criticisms. One common critique is the "one-size-fits-all" nature, as these funds base their asset allocation primarily on a single factor: the target retirement date. This approach may not adequately account for an individual investor's unique risk tolerance, other assets, or personal financial goals. For example, some studies suggest that target date funds have underperformed simpler, static asset mixes over long periods due to their rigid allocation rules and potential over-reliance on certain bond types.5, 6, 7
Another area of concern revolves around fees. While the average expense ratio for target date funds has generally decreased over the years, they may still carry higher costs compared to basic index fund alternatives that track broad market benchmarks.3, 4 Critics argue that these additional fees can erode long-term returns, particularly when the fund's underlying investment choices do not consistently outperform lower-cost options. Furthermore, variations in glide paths among different fund providers mean that a "2050 fund" from one company might have a significantly different risk profile than a "2050 fund" from another, leading to potential investor confusion.2 Some argue that these funds, by their rigid nature, may not adapt quickly enough to changing capital markets or economic conditions, potentially hindering performance.1
Target Date Funds vs. Balanced Funds
Target date funds and balanced funds both invest in a mix of asset classes, typically stocks and bonds, to create a diversified portfolio. However, their fundamental approach to asset allocation differs significantly.
| Feature | Target Date Funds | Balanced Funds |
|---|---|---|
| Asset Allocation | Automatically adjusts over time according to a predetermined "glide path," becoming more conservative as a specific target date (e.g., retirement) approaches. | Maintain a relatively static mix of assets, often adhering to a fixed proportion (e.g., 60% stocks, 40% bonds). |
| Investor Input | Designed for minimal investor input; "set-it-and-forget-it" convenience. | Requires the investor to choose a fund that aligns with their desired risk level and potentially rebalance manually. |
| Goal | Geared towards a specific future event, commonly retirement, with the portfolio becoming increasingly conservative. | Aims for a balance of growth and income, suitable for various investment objectives without a predefined "end date" adjustment. |
| Underlying Strategy | Dynamic asset allocation based on time horizon. | Static or tactically managed asset allocation. |
While both aim for diversification and professional management, the key distinction is the automatic, time-based adjustment inherent in target date funds. Balanced funds require investors to actively select a fund with a risk-reward profile that matches their needs and, if desired, to periodically rebalance their overall portfolio.
FAQs
What is a "glide path" in the context of target date funds?
A glide path refers to the predetermined schedule by which a target date fund's asset allocation shifts over time. It dictates the gradual reduction of risk, moving from a higher concentration of equities to a greater proportion of bonds and cash as the target date approaches.
Are target date funds guaranteed investments?
No, target date funds are not guaranteed investments. Like all investments, they carry inherent risks, and their value can fluctuate based on market conditions. The asset allocation within the fund is designed to manage risk over time, but it does not eliminate the possibility of losses.
How do I choose the right target date fund?
When selecting a target date fund, consider your expected retirement year and align it with the fund's target date. Beyond the date, it is crucial to examine the fund's specific glide path, its underlying investments, and its expense ratio. Some funds maintain a more aggressive stance closer to retirement ("through" glide path), while others become very conservative ("to" glide path), so understanding these differences is important for your personal risk tolerance.
