No bonds! No bonds! No bonds! Why would you include bonds in your portfolio if you aren’t within a few years of retirement? Yes, I know bonds provide a less volatile portfolio with a minor reduction in return. Why would anyone want that?
Most people have the majority of their retirement in their 401k or IRA. Assuming that who cares about volatility! If you are 20, 30, 40…even 50 you probably won’t be pulling any money out of these vehicles any time soon. These accounts are not being used to save for a house, a new car or a vacation, so what do you care if your account goes down 20% this year. A loss in an account you aren’t going to touch for 20 years…big deal.
Of course, along with larger potential loses come larger potential gains. Maybe you get a 30% return the next two years and easily outpace the 7-9% target on a “properly” allocated portfolio.
So, let’s take a look at the returns produced by different mixes of stocks and bonds. These numbers are from 1980 to 2004, so the overall return is a little higher than normal due to the huge bull market. However, the curve is very consistent no matter what time period you use, so the chart is applicable.

As you can see the more stocks the more risk/volatility, but as we have already discussed who cares. The difference of return between an 80/20 stock/bond portfolio and 100% stock portfolio is roughly .5-1%, based on the above graph. This doesn’t seem like much, but it adds up over time.
Also, how much are the bonds really protecting? Let’s assume you are 2-3 years from retirement and the worst happens. We experience a stock market disaster equivalent to the worst in modern history (after the Great Depression), which would be from January 1973 to December 1974 and results in a 45% drop in your stock portfolio. Now assume two people have been consistently saving and investing $10,000 a year for 30 years. One person did the 80/20 method, so they averaged a 7% return per year. The second person invested in 100% stocks and averaged an 8% return per year. As you can see both returns are easily within historical norms, so no wild assumptions have been made.
After 30 years person one, with the 80/20 portfolio, has $1,005,750, while person two, with the 100% portfolio, has $1,216,005. Unfortunately, one year before retirement, in year 31, a huge bear market occurs causing a 45% drop in the market. Person one is pleased they were “smart” enough to have allocated 20% of their portfolio to bonds, so they get a 4% return from the bonds and are hit with a 45% loss on 80% of the portfolio in the stock market. All of this brings person one’s retirement to $651,726 from $1,005,750, which is only a 35% loss for the entire portfolio.
Person two with a 100% stock portfolio gets hit with the full 45% drop. Well, this should be pretty bad…right? Nope…their $1,216,005 portfolio is now worth $668,903.
Hmmm…person two with the “risky” 100% stock portfolio had $17,076 more for retirement after the largest market drop in 40 years and the second largest drop in 80 years. How is that possible when person two failed to maintain a conservative portfolio? It’s because you can’t make up for years and years of poor returns by investing like the world is going to collapse every year. Being conservative doesn’t improve your odds of retiring; it increases the risk you will not have enough money to retire on by lowering the total return of your portfolio.
I’m not advocating holding 100% stocks a few years before retirement, I’m saying don’t even think about bonds until your within 10 years of retirement…even then, think about waiting a little while longer.
Don’t accept below average returns in a portfolio when volatility doesn’t matter! A 100% stock portfolio is the only way to go.
