Follow the Leaders

This week the investment community mourned the death of John Bogle, the founder of Vanguard, the mutual fund giant. He had the crazy idea that mom-and-pop investors should buy a basket of stocks and not attempt to beat the market (Note #1). In 1976, he launched the first SP500 index fund, VFINX, a low-cost “no-brainer” or passive fund. Because people did not want to invest in the idea of earning just average stock returns, the initial launch raised very little money. “Bogle’s folly” now has more than fifty imitators (Note #2).

Vanguard has over $5 trillion under management. Let’s turn to them to answer the age-old question – what percent of my retirement portfolio should be invested in bonds? Bond prices are much less volatile than stocks and stabilize a portfolio’s value. Several decades ago, people retired at 65 and expected to live ten years in retirement. An old rule was that the percentage of bonds and cash should match your age. A 50-year old, for example, should have 50% of their portfolio in bonds and cash. Few advisors today would be so conservative. Many 65-year-olds can expect to live another twenty years or more.

Vanguard, Schwab, Fidelity and Blackrock offer various life cycle funds that have target dates. The most common dates are retirement; i.e. Target 2020, or 2030 or 2040. These funds are composed of shifting portions of stock and bond index funds offered by each investment company. The funds adjust their stock and bond allocations based on those dates. For example, if a 55-year old person bought the Vanguard Retirement Target Date 2020 Fund VTWNX in 2005, it might have been invested 75% stocks and 25% bonds when she bought it. As the date 2020 nears, the stock allocation has decreased to 53% and the bond portion increased to 47%. The greater portion of bonds helps stabilize the value of the portfolio.

In the chart below, I’ve compared the stock and bond allocations of various retirement funds offered by Vanguard (Note #3). Notice that the stock portion of each fund increases as the dates get further away from the present.

A 46-year old who intends to retire in 2040 when they are 67 might buy a Target 2040 fund which is 84% invested in stocks. The bond allocation is only 16%. Using the old rule, the bond portion would have been 46%.

What happens after that target date is met? The fund continues to adjust its stock/bond allocation towards safety. Over five years, Vanguard adjusts its mix to that of an income portfolio – 30% stocks and 70% bonds (Note #4).

These strategies can guide our own portfolio allocation. I have not checked the allocations of Schwab, Fidelity and others in the industry but I would guess that they have similar allocations for their life cycle funds.
