Home Insights Asset allocation Retirement ready: The power of target date funds

In the landscape of retirement planning, target date funds (TDFs) have emerged as a pivotal innovation. These funds are designed to simplify the investment process for individuals saving for retirement, catering specifically to the needs of those who may lack the expertise or time to manage their investment portfolios actively. TDFs automatically adjust their asset allocation, recognizing the gradual shift in focus from wealth accumulation to wealth preservation as the target retirement date approaches, providing a streamlined risk management and strategic investment solution.

As seen in the table above, total assets in target date funds reached very nearly $4 trillion in 2024 after reaching roughly $3.5 trillion in 2023. They have accounted for nearly all net inflows into the defined contribution space over the last five years— illustrating their emergence as the default option in retirement plans. Beyond just the previous decade’s bull market, there are several reasons for this growth: TDFs simplify investment decisions, provide automatic risk management over time, and serve as a compelling choice for participants who may otherwise struggle with actively deciding among an array of investment strategies.

How target date funds emerged as the default option

Inadequacy of single asset class lineups

Historically, many retirement plans often consisted of single asset class lineups—such as equities, fixed income, or stable value—but those usually failed to address the diverse needs of investors. These limited offerings frequently left individuals without the knowledge or motivation to effectively manage their risk exposure throughout their investment horizon. As a result, many participants in these plans remained unaware of how to adjust their portfolios based on changing market conditions or personal circumstances. A lot of young workers invested too conservatively, and investors nearing retirement found themselves investing too aggressively. Many simply selected the option with the best performance.

Evolution from target risk portfolios

Target risk portfolios were introduced as a solution to cater to different investor risk profiles. This solution was designed to maintain a constant risk level, regardless of an investor’s age. These portfolios, however, lacked the essential feature of automatic risk reduction as participants moved closer to retirement, often leaving individuals in higher-risk allocations longer than appropriate. The shortcomings of these traditional approaches underscored the need for a more dynamic solution—paving the way for the emergence of target date funds.

How target date funds operate

The glide path concept

The concept of a “glide path” is central to understanding how target date funds operate. The glide path refers to the gradual shift in asset allocation as the target retirement date approaches. Investors select a fund corresponding to their anticipated retirement date, which serves as the guiding framework for investment allocation. As the “target date” approaches, professional fund managers gradually shift away from riskier assets, such as equities, toward more conservative assets, such as bonds and cash equivalents. This gradual and automatic transition in a target date fund minimizes risk and aims to protect accumulated savings as investors transition from wealth accumulation to wealth preservation.

Simplicity and convenience

One of the most attractive features of TDFs is their simplicity. Instead of juggling multiple investments, individuals can invest in one fund that aligns with their anticipated retirement date. Furthermore, with investment professionals managing all major asset allocation and rebalancing decisions, the need for hands-on involvement from investors is practically eliminated. This “set it and forget it” approach is particularly valuable for busy, uninterested, or inexperienced participants who may not have the time or expertise to manage their investments actively.

Advantages of target date funds

Automatic asset allocation

Target date funds offer automatic asset allocation that continuously adjusts the mix of investments that can significantly benefit investors who don’t have the time to manage their savings. This dynamic approach allows for a smoother transition from growth-focused investing—typically favored in the early years of saving—to preservation-focused investing as retirement nears.

One of the standout features of TDFs is their glidepath, which assists participants in transitioning seamlessly from accumulation to wealth preservation as they near retirement. This built-in risk reduction is particularly advantageous for near-retirees, who may not have the time to recover from significant market downturns as the gradual shift towards more conservative investments helps to protect their savings as they prepare for retirement. An example of a typical glidepath is illustrated below.

Professional management, diversification and behavior

Experienced fund managers design TDFs by creating a well-diversified blend of equities, bonds, and other asset classes using a combination of strategic and tactical asset allocation. Strategic asset allocation establishes the fund’s long-term investment framework, determining the optimal mix of asset classes based on the desired risk and return profile over time. Tactical asset allocation, on the other hand, involves making shorter-term adjustments to overweight or underweight specific asset classes – such as small-cap stocks, international equities, high-yield bonds, credit risk or real estate -in response to market conditions and opportunities. This professional investment management aims to reduce concentration risk in any single asset type, enhance long-term return potential, and maintain portfolio resilience. By diversifying investments across multiple asset classes, TDFs can better navigate market volatility and potentially deliver more stable returns over time.

Experienced fund managers use strategic and tactical asset allocation to diversify investments, reduce concentration risk, and potentially deliver stable returns over time.

Investment managers are also responsible for regularly reevaluating their glide paths, especially in response to significant changes in financial markets. This process is often data-driven, involving an analysis of long-term capital market behavior and assumptions, including the risk and return profiles of various asset classes across historical and expected market cycles. To optimize outcomes for different risk levels, managers may also utilize accumulation and spending models to refine their strategies.

Behavioral finance is also something to monitor closely. Understanding how savers and investors behave is essential to optimal retirement savings outcomes. How do withdrawal rates and savings rates change? How do workers respond to market shocks and left-tail events that may lead to occasional and sudden drops in portfolio balances? If workers withdraw from risk assets too early in the wealth accumulation cycle, that can profoundly impact their retirement savings. Behavioral finance research tells us that certain age groups tend to have different risk tolerances. When that risk tolerance is breached in the form of a market drawdown, there is an increased chance of portfolio abandonment risk. This is a worst-case scenario: abandoning your retirement portfolio near a market bottom. Professional managers design the glidepath with this in mind to mitigate this risk.

Target date funds address one additional and potentially devastating aspect of behavior finance: human inertia. Target date funds turn the risk of “investing and forgetting” into an advantage, relieving savers of the responsibility to check on their risky investments as they age closer to retirement. Investors who do not derisk may suffer sequential return risk at the exact worst time of their retirement savings journey, right at retirement. The glidepath addresses human inertia by derisking automatically.

Ease of use for plan sponsors

TDFs have gained widespread adoption by plan sponsors due to their regulatory acceptance and cost-effectiveness. They serve as an efficient “plug-and-play” option for automatic default investments. This simplicity benefits sponsors and enhances the overall effectiveness of retirement plans, making it easier for participants to engage with their retirement savings. Moreover, TDFs help plan sponsors address their fiduciary responsibilities with far less effort than in the era before these portfolios were introduced.

Potential drawbacks and considerations

One-size-fits-all approach

Despite their many advantages, target date funds are not without their drawbacks. One concern often raised by prospective investors is TDFs one-size-fits-all approach. TDFs may not always account for individual investors’ unique risk tolerance or personal circumstances. This potential misalignment can lead to participants investing in funds that do not adequately reflect their unique financial goals or risk appetites.

Fees and expenses

While TDF managers provide professional management and rebalancing, these services come at a cost. Although fees have declined over the years, they can still represent a significant expense for investors, especially when compounded over time. Investors should be aware of these costs and assess whether the benefits of professional management outweigh the associated fees. One solution to this issue is the emergence of passive and hybrid TDFs, which typically offer lower fees to investors but often provide similar functionality, including glide paths, simplicity, and automatic asset allocation.

Need for periodic review

Although TDFs aim to simplify decision-making, it is essential for advisors and participants to periodically evaluate whether the chosen target date fund remains suitable for their evolving goals. Changes in personal circumstances, market conditions, or retirement objectives may necessitate adjustments to investment strategies, and regular reviews can help ensure the chosen TDF remains aligned with the investor’s needs.

Actionable recommendations

TDFs as a cornerstone of modern retirement plans

Target date funds have evolved into a cornerstone of modern retirement planning. For individuals who might otherwise remain in unsuitable allocations, TDFs provide a structured approach to investing that adapts to changing needs over time. Their automatic features and professional management make them an attractive option for many investors.

To maximize the benefits of TDFs, advisors should conduct ongoing due diligence. This involves ensuring that the glidepath and underlying fund structure align with each client’s unique financial and risk profiles. Customization, through separately managed accounts, can help mitigate the risks associated with the one-size-fits-all nature of TDFs, allowing for a more tailored approach to retirement planning.

Next steps

Regular plan reviews, fee analysis, and client education sessions are essential to optimize the use of ever-evolving types of target date funds within retirement portfolios. By better understanding the different flavors of TDFs and their potential impact on retirement savings, advisors can empower clients to make informed decisions that enhance their financial well-being.

To maximize TDF benefits, advisors should conduct ongoing due diligence, ensuring that glide paths and fund structures align with clients’ unique financial profiles.

Target date funds offer a compelling solution for retirement planning, addressing many of the challenges individual investors face. As retirement landscapes continuously change, TDFs stand out as a dynamic and effective tool for navigating the complexities of investment management. With the proper guidance and periodic evaluation, these funds can play a crucial role in securing a financially stable retirement for individuals across various demographics.

Risk considerations

Past performance is no guarantee of future results. Investing involves risk, including possible loss of principal. Equity investments involve greater risk, including heightened volatility, than fixed income investments. Fixed‐income investment options are subject to interest rate risk, and their value will decline as interest rates rise. Lower-rated securities are subject to additional credit and default risks. Investment risk may be magnified with alternative investment strategies due to their use of arbitrage, leverage, and derivatives. Neither the principal nor the underlying assets of target-date portfolios are guaranteed at any time.

Target-date portfolios are managed toward a particular target date, or the approximate date the investor is expected to start withdrawing money from the portfolio. As each target-date portfolio approaches its target date, the investment mix becomes more conservative by increasing exposure to generally more conservative investments and reducing exposure to typically more aggressive investments. Neither the principal nor the underlying assets of target-date portfolios are guaranteed at any time, including the target date. Investment risk remains at all times. Neither asset allocation nor diversification can ensure a profit or protect against a loss in down markets. Be sure to see the relevant prospectus or offering document for a full discussion of a target-date investment option including determination of when the portfolio achieves its most conservative allocation.

Asset allocation and diversification do not ensure a profit or protect against a loss. The risk management techniques discussed seek to mitigate or reduce risk but cannot remove it. Inflation and other economic cycles and conditions are difficult to predict and there is no guarantee that any inflation mitigation/protection strategy will be successful.
