5 Steps to a Minimalist Portfolio

Even if you’re not an investment collector—ahem, you know who you are—it’s a good bet that the number of holdings and accounts in your portfolio have grown right along with your age and net worth.

As assets grow, it’s only natural to want to diversify across investment types and perhaps even delve into investment arcana, such as commodities or private real estate. Accounts can also stack up as the years go by, especially 401(k)s and IRAs.

Thanks to all of these forces, investors can readily end up with what I think of as “portfolio sprawl”—too many accounts and too many holdings within them. Diversification is desirable, but when taken to an extreme, it can become difficult to keep tabs on what you have. That’s particularly true if you have individual stocks and actively managed mutual funds, which require at least some level of ongoing oversight. Portfolio sprawl can also make portfolio maintenance a heavier lift, since it’s harder to get your arms around your total asset allocation. Tax time may be more complicated than it needs to be, too.

The good news is that with a little bit of effort, it’s possible to arrive at a minimalist portfolio with fewer moving parts—both accounts and holdings.

Here are the five steps to a minimalist portfolio:

1. Inventory and document what you have.
2. Consolidate like accounts.
3. Revisit your target asset allocation.
4. Populate the accounts with simple building blocks.
5. Establish a plan for keeping it up to date.

Step 1: Inventory and document what you have.

The first step in the process is to conduct an inventory of your financial accounts. You can stick narrowly to your investments, but I’d recommend that you broaden the inventory process to encompass all of your financial relationships—banking, insurance, and so on. As you do so, document all of your account information—account numbers, passwords, financial professionals you deal with, and so on. You can use a spreadsheet for this job. Encrypt the document or, if it’s something that you plan to print out, keep it under lock and key. This document will help you identify streamlining opportunities and, if you keep it updated, can be a guide for your loved ones to know what you own if they need to help manage your accounts at some point.

Step 2: Consolidate like accounts.

The next step toward a minimalist portfolio is to identify opportunities to merge accounts of the same type. If you’ve been saving and investing for a while, you probably have assets in tax-deferred vehicles like IRAs and 401(k)s, Roth accounts, and taxable/nonretirement accounts; you might also have health savings accounts. While it’s usually not advisable and may not even be possible to combine assets held in different tax silos, duplicate accounts of the same type provide prime opportunities for streamlining. By carefully following the rules for combining like account types and letting the firms deal with one another to execute the transfer of funds, you should be able to streamline without causing a taxable event.

Tax-deferred accounts can be particularly ripe for consolidation: The typical American has 12 jobs in their lifetime, so that means that many workers have multiple tax-deferred retirement accounts, both company-sponsored retirement plans and IRAs. Consolidating those accounts into a single IRA provides a major streamlining opportunity. (If one of the 401(k)s is gold-plated and accepts “roll-ins”—outside assets—consolidating there may be advisable. Ditto for people who need the extra creditor protections that employer-provided accounts may confer.) And as high-deductible healthcare plans with health savings accounts proliferate, more employees will end up with multiple HSAs, too. Identify the best HSA of the bunch using Morningstar’s HSA research and transfer funds from the also-rans to a single mega-HSA. (Just remember, HSAs—like IRAs and 401(k)s—can only be owned by individuals. So if you’re part of a married couple, remember that you can’t merge accounts with different owners.) Finally, many households have multiple small brokerage and bank accounts that can readily be combined.

From a practical standpoint, this part of the job can be a bit of an administrative headache. If you need assistance in executing a transfer, it’s often easiest to get help through the “receiving” firm (that is, the company that you’re transferring the assets into) rather than the one you’re exiting.

Step 3: Revisit your target asset allocation.

Once you’ve finished the account-consolidation process, it’s a good time to reconsider your portfolio’s asset allocation, particularly if you haven’t done so for a while. You can use the portfolio tool in Morningstar Investor to examine your current asset-class positioning and compare it with your targets. If you don’t have targets and expect to use the assets for retirement, good target-date funds can help you get in the right ballpark.

Step 4: Populate the accounts with simple building blocks.

Armed with targets for your portfolio’s asset allocation, you can then switch into an ultrasimple, minimalist portfolio mix. The goal of a minimalist portfolio is to use the fewest number of holdings to achieve diversification. Broad-market index funds and exchange-traded funds lend themselves particularly well to this effort, providing broad asset-class exposure in a single shot and with very low expenses. If you have small accounts, all-in-one funds like target-date funds can be a terrific solution, especially if you’re not yet retired. (In retirement, I like the idea of maintaining discrete exposure to asset classes, the better to pick and choose where to go for cash on an annual basis.)

Making changes to tax-sheltered portfolios—tax-deferred and Roth retirement accounts and health savings accounts—won’t result in any taxes as long as the funds stay inside the account shell. However, you’ll want to take care when making changes to your taxable accounts because selling appreciated assets can result in a tax bill. If your taxable accounts require a major overhaul, be sure to get some tax advice and/or calculate the tax bill before proceeding.

Step 5: Establish a plan for keeping it up to date.

Establishing a minimalist portfolio will mean few oversight obligations on an ongoing basis. But unless you’re sticking with target-date funds or some other self-managed option, you’ll still need to keep tabs on your portfolio’s asset allocation as the years go by. I like the idea of using an investment policy statement to document the parameters of your portfolio—your asset allocation, how often you’ll monitor your portfolio, and what the catalysts will be for making changes. With a minimalist portfolio in place, a good annual checkup is all you really need, and you’ll probably have to make changes even less frequently than that.
