What Is the Couch Potato Portfolio?

Scott Burns created the Couch Potato Portfolio in 1991. In terms of Lazy Portfolios, the Couch Potato Portfolio is about as simple as it gets: a 50/50 mix of stocks and bonds, using only 2 funds. Burns maintains that this makes it probably the most accessible and easy-to-understand portfolio out there, stating that anyone who “can divide by 2” can understand it.

The basic premise for the 50/50 allocation is, again, simplicity, and the idea that stocks can drive returns while bonds help protect against stock crashes and lower the portfolio's volatility. The portfolio is essentially a slightly more conservative version of a traditional 60/40 portfolio.

Interestingly, adherence to Burns's precise prescription of funds for the Couch Potato Portfolio doesn't seem to be required, and varies among investors. That is, you could use an , total US stock market fund, or total world stock market fund on the equities side. On the bonds side, you could use intermediate treasuries, total bond funds, etc.

In fact, Burns tells of how immediately after initially he initially published the portfolio, readers called in to ask him exactly how to implement it. Burns himself has actually used several different recommendations of specific assets over the years, all while keeping it pretty general and still allowing you to DIY it. In describing the original iteration of Couch Potato Portfolio, Burns suggested an S&P 500 index fund and a short-term government bond fund. Fast forward to 2018, and he mentions total stock market funds and total bond market funds.

Burns submits that more important than the fund choices are the fundamental requirements of low-fee indexing, diversification, and simplicity, and states that “the single most important thing is the basic 50/50 mix of stocks and bonds.” This is consistent with Burns's writings on investing; he aims to be “an antidote to Wall Street.” The idea is that you can sit on the couch, check and rebalance this portfolio once a year, and let it do its thing.

Burns describes the implementation of the Couch Potato Portfolio in an article from 1991. I would highly suggest checking it out, if for no other reason than to get a laugh. Here are some direct quotes from the article:

Try this: once a year – like when you add new money – you take the total value of your investment and divide by “2”. That tells you how much you need in stocks. And in bonds. So you move some money, as necessary, from stocks to bonds. Or vice versa. With telephone exchange privileges at most mutual fund families, you can do this is less time than it takes to go to the refrigerator. Indeed, as a timing exercise, I suggest you put a medium sized potato in your microwave: your annual portfolio management will be done in less than the 10 minutes it takes to cook the potato.

Call Vanguard, the mother of all indexers, at 800­662­7447, and ask to make the minimum investment in the Vanguard Index 500 fund, which mimics the Standard and Poors' 500 index, and the Vanguard Fixed Income Short Term Government Bond Fund. Both have minimum investments of $3,000 and allow additional investments of only $100. That means you start with $6,000 and add as little as $100 at a time after that.

Since the broad index funds used are somewhat arbitrary, for the sake of this blog post and the analysis herein, I'm choosing to use Vanguard's Total US Stock Market ETF (VTI) and the iShares U.S. Treasury Bond ETF (GOVT).

• Why total US stock market (VTI) instead of the S&P 500 (VOO)? The S&P 500 is comprised of roughly 500 large-cap stocks. Using a total stock market fund, we increase diversification (VTI contains about 3,500 stocks) and get exposure to some small- and mid-caps, which have outperformed large-caps historically.
  
• Why total US stock market (VTI) instead of total world stock market (VT)? If I were investing in the Couch Potato Portfolio, I would probably use the total world stock market (VT) to increase diversification and get exposure to ex-US equities at their market weights. However, I realize that the vast majority of investors seem to prefer to embrace home country bias and only allocate 20-30% max to ex-US stocks, using a combination of VTI and VXUS (total ex-US stock market). Since the Couch Potato Portfolio requires the use of only 2 assets to maintain the fundamental simplicity, that's not an option here. I've created a global pie version using VT that I include at the bottom of this post.
  
• Why treasury bonds instead of corporate bonds? Treasury bonds should be preferable to corporate bonds due to their superior volatility reduction and black swan protection in a long-term diversified portfolio, and have the added benefits of allowing you to avoid state and local taxes, credit risk, and liquidity risk that accompany corporate debt.
  
• Why treasury bonds instead of total bond market? Total bond market funds contain some allocation to corporate bonds, usually 25-30%. See above point.

So, without further ado, my interpretation of the Couch Potato is as follows:

• 50% Total US Stock Market (VTI)
• 50% Total US Treasury Bond Market (GOVT)

Interestingly, Jack Bogle, the founder of Vanguard and considered the pioneer of index investing, said this was basically what his own portfolio looked like.

Couch Potato Portfolio Performance Backtest

Going back to 1972, here's the Couch Potato Portfolio's performance vs. the S&P 500 through July, 2021:

I have to admit I expected the difference in return between these 2 portfolios to be much greater. Interestingly, the Couch Potato Portfolio achieved a lower CAGR than the S&P 500, with roughly half the volatility, much smaller drawdowns, and much higher risk-adjusted return (Sharpe). This is from the bonds doing their job of protecting from the downside risk of stocks. Granted, most of this time period – after 1982 – was great for bonds. The future may look different.
