Should you keep your asset allocation simple or make it more complex?

You’ll usually choose between simple portfolio strategies and complex asset allocations. Both offer benefits and drawbacks, so compare carefully before deciding what matches your goals.

When it comes to building your investment portfolio, two main approaches often come up for discussion: simple strategies like target date funds or portfolios with just a few selected securities, versus more nuanced, complex asset allocation models. Each has its merits—and its challenges. Here’s what you need to know before choosing the right approach for your financial goals. 

Why simple asset allocation strategies make sense

Simple strategies are popular for good reason. They’re easy to understand and easier to implement. Options like target date funds are designed to be hands-off. With a ‘set it and forget it’ model, these funds require minimal maintenance and align with your expected retirement timeline. For those not interested in target date funds, a straightforward 80/20 split between stocks and bonds, US and international or similar strategies allows investors to quickly start investing without extensive research or technical expertise.1 

These approaches are easy to explain because they rely on straightforward concepts that don’t require extensive technical knowledge. They are also easy to implement, as they involve clear, step-by-step processes that don't require advanced training or tools. That said, keeping your portfolio in a spreadsheet still requires manual work, and can lead to suboptimal outcomes. Even in a simple strategy, you may want to explore a portfolio tracker to replace spreadsheet.

Why more complex strategies make sense

Often we have more assets than we realize. Target date funds and basic portfolios operate in isolation. They don’t consider external assets like your primary residence, RSUs from your employer, or investments in cryptocurrency. Ignoring these factors could skew your overall portfolio and tilt your risk exposure in ways you didn’t intend. For those in medicine or working in tech, their employer already leans their portfolio heavily to their respective sectors. Investing directly in the S&P500 may cause these investors to double down on their sector because of the overlap.

Additionally, for those who have researched asset allocation approaches, simple strategies don’t account for fine-grain factors, such as the split between U.S., international, and emerging market  stocks or large-cap versus small-cap equities. This lack of specificity can inadvertently expose you to unaccounted risks or missed opportunities.

Lastly, simple models can't adapt as your life changes—whether you receive a promotion with stock options, diversify into alternative assets, or need to rebalance for tax efficiency. They might lack the flexibility to grow with your evolving financial landscape. 

However, these complex approaches have two major drawbacks. (1) it requires education to determine what the right asset allocation is for your personal circumstances, and (2) maintaining a more complex asset allocation may require more overhead.

Frequently asked questions

When is a three-fund portfolio not enough?
It may be insufficient if you have large single-stock risk, specific factor tilts you care about, or unique liabilities you want to hedge. Otherwise, it’s usually adequate for many investors.
Do I need a more complex portfolio if I have RSUs or company stock?
Not necessarily, but you should monitor concentration; it’s common to set a maximum, like 5%–10% of net worth, and gradually diversify excess over time.
Does a more complex asset allocation actually improve returns?
Many criteria, just to gain a little more return, may not pay off if the portfolio is harder to run. For most DIY investors, a simple mix you actually rebalance beats a fancy setup you can’t maintain.
