Target date retirement funds are effective up to a certain point. Here's when you may need to reevaluate your options.

• As you near retirement, these funds automatically adjust their investments from riskier to more conservative options, allowing you to put your savings on autopilot.
• According to Morningstar, approximately $1.8 trillion is invested in target date mutual funds.
• It may be necessary to reassess the suitability of a particular fund in your investment portfolio at certain times.

It is wise to reevaluate a retirement-savings plan at the beginning of your career.

Target-date funds provide an option to automate your savings plan by gradually shifting your investments from riskier assets, such as stocks, to more conservative options, like bonds and cash, as you near retirement.

It may be necessary to reassess your target date fund when approaching retirement, as these funds may not be suitable for your situation in the long run.

In your mid-50s, when you're approximately 10 years from retirement, it's crucial to adopt a holistic perspective and examine your entire financial situation, advised Chris Mellone, a Certified Financial Planner and financial advisor at VLP Financial Advisors in Vienna, Virginia.

Mellone stated that a tailored asset allocation strategy is necessary for this group of investors.

According to Morningstar, roughly $1.8 trillion is invested in target date mutual funds. Vanguard reports that 98% of 401(k) plans include this type of fund in their lineup. Additionally, 80% of all 401(k) participants are invested in these funds.

Target-date funds are a practical option for young investors or those with limited experience, as they have an asset allocation that reflects a long-term retirement horizon (up to 95% in stocks), and they offer automatic rebalancing and de-risking over time.

That usefulness can change, however.

Charles Sachs, chief investment officer for Kaufman Rossin Wealth in Miami, stated that the downside is that you put it on autopilot for 20 years, and as it grows, you advance in your career and life, and you acquire other assets.

Sachs stated that when the target fund is working independently, it is essential to coordinate.

If your target date fund is 70% in stocks and 30% in bonds, and you have money in another fund that's invested solely in stocks or a stock index, your stock-bond ratio could be more like 90%-10%, which may not be appropriate for your risk tolerance.

If they add investments to their portfolio, they may not be aware of the additional risk they're taking on, as their allocation may no longer match their expectations, according to Megan Pacholok, an analyst with Morningstar.

Target date funds typically maintain their investments in stocks until they reach their target year, although some may adjust their equity holdings. For example, the average 2020 target date fund currently has approximately 46% in bonds, 42% in stocks, and the remaining percentage in cash and other investments, according to Morningstar Direct. The average stock-bond mix for 2025 target date funds is 47%-39%.

Although some advisors suggest that it is acceptable to continue using target date funds in retirement, others argue that there are reasons to reevaluate this option.

If you need to withdraw funds during a market downturn, you may have to sell stocks, regardless of your preference.

Mellone advised against indiscriminately taking distributions from a target date fund, suggesting instead that it's better to break down the pieces and assess what makes the most sense for funding distributions.

To avoid selling volatile investments in a down market during retirement, it is advisable to plan for a certain number of years' worth of income, such as five years, which would require $500,000 in cash and bonds.

As your financial life becomes more intricate or you approach retirement, it's crucial to reassess whether your target date fund remains suitable.

"Track it to determine if it's working for or against you, as Sachs advised. Don't forget to monitor it," said Sachs.
