Maximizing Your Portfolio's Potential: The Case for Unbundling Asset Classes
When it comes to investing, simplicity is often touted as a virtue. Total market funds, in particular, offer a straightforward and low-maintenance way to diversify your portfolio. However, this approach can also lead to a lack of flexibility and potential missed opportunities for growth. By unbundling asset classes and leveraging automation, investors can create a more tailored and effective investment strategy. Target date funds, which have become a popular option for retirement savings, are a prime example of this trade-off between simplicity and potential.
The Limitations of Target Date Funds
Target date funds have been a staple of retirement planning since the 1990s, and their growth has driven the industry towards lower-cost, automated investing. However, these funds often come with constraints, including a relative lack of choice and limited ability to fine-tune your exposure to different asset classes. For instance, if you're targeting a traditional retirement age, you may be limited to a single fund option, such as the 2050 fund. In contrast, automated investing platforms like Betterment offer a range of portfolios to choose from, including those tailored for social responsibility and innovation. This increased flexibility allows investors to better manage risk and optimize their returns.
Optimizing Your Portfolio for Maximum Savings
One of the key benefits of unbundling asset classes is the potential for cost savings. While the expense ratios of target date funds have been trending downward, there is still room for optimization. By splitting a portfolio into multiple funds, investors can take advantage of lower-cost options and minimize their overall expenses. For example, instead of paying 6 basis points for a total world stock fund, investors could pay one-third of that by breaking it up into three separate funds. This may seem like a small difference, but it can add up to significant savings over time. In fact, using Betterment's Core portfolio as an example, this approach could result in combined savings of roughly $7.6 million per year for customers with nearly $20 billion worth of U.S. stocks.
Unlocking the Full Potential of Your Investments
A simple portfolio can be a great starting point, but it's not always the most effective way to achieve your investment goals. By strategically using a few more funds, investors can sprinkle tax advantages on more of their investments, optimize across account types, and potentially unlock even more cost savings. The key is to strike a balance between simplicity and flexibility, using technology to do the heavy lifting behind the scenes. With the right approach, investors can enjoy the benefits of a streamlined portfolio while still maximizing their returns.
