Should You Be In an Asset Allocation Fund?

February 09, 2017

One of the most common questions we get on the Financial Helpline is how to choose investments in your employer’s retirement plan. Investing can be complex and intimidating so it doesn’t surprise me that people are looking for help with their decision. What does surprise me is how few of them understand and use an option that was created to help simplify their decision.

Depending on your plan, you may have a target date or a target risk fund available to you. Both are “asset allocation funds” that are designed to be fully-diversified “one stop shops.” All you need to do is pick one fund that most closely matches your target retirement date or your risk level. (Target date funds can also be “set it and forget it” because the funds automatically become more conservative as you get closer to the target retirement date.)

If you think of investing as getting you from point A to point B, asset allocation funds are like the commercial jets of investing. They’re much cheaper than a private jet (a financial advisor) and much simpler than piloting your own plane (picking your own investments). That’s why when I first heard about these funds early in my financial career, I assumed they would take over much of the mutual fund industry and even replace the need for a lot of financial advisors. While they have seen a meteoric rise, especially as the default option in retirement plans, they still aren’t utilized as much as I thought they would be. I think there are 3 main myths responsible for this:

1. Putting everything in one asset allocation fund is having all my eggs in one basket. What you don’t see is that an asset allocation fund is actually a basket of baskets. Each fund is composed of several other funds. In fact, one asset allocation fund is usually more diversified then the typical mix of funds that I see people in.

So why not have other funds in addition to it? Isn’t that making your portfolio even more diversified? The problem here is that these funds were professionally designed to hold a certain proportion of investments so adding others will throw the balance off. It’s like adding extra ingredients to a chef-prepared meal. Only do it if you really know what you’re doing (in which case, you probably don’t need an asset allocation fund anyway).

2. I can probably do better on my own. Remember that these funds were put together by professional money managers who’ve been trained in investment management and do this for a living. What’s the chance that you’ll create a better portfolio? One study of 401(k) participants showed that investors who chose their own funds did worse on average than those who just went with a target date fund.

Part of that is due to lack of knowledge. However, a lot is also likely due to the temptation to buy investments that are performing well and then sell them when they eventually underperform, which is a recipe for buying high and selling low. If nothing else, asset allocation funds provide discipline… assuming you don’t trade these funds too of course.

3. Asset allocation funds are always more expensive. You would think that this professional management would come at a steep price. After all, paying for investment management typically costs .5-1% of your portfolio. However, asset allocation funds are generally only slightly more expensive than other funds and if they’re composed of index funds, they can actually cost much less than most actively managed funds. Check the fund’s expense ratio before making assumptions as to their cost.

That all being said, there are reasons not to use an asset allocation fund. You may not have one available in your plan or the one you have may be too expensive. Sophisticated investors or those with an advisor may want to create a more personalized portfolio that better matches their risk level or complements outside investments to maximize tax-efficiency. But if those situations don’t apply to you, consider an asset allocation fund. Flying commercial may not be a perfect experience, but it’s better than the alternatives for most people.
