According to the Employee Benefit Research Institute, 22% of people in their 60s have more than 80% of their 401(k)s allocated to equities.

With only a few years left until retirement, an 80% allocation to stocks is asking for trouble. An 80-20 mix of stocks and bonds can experience crushing losses that are difficult to recover fromโ€”especially if one is already taking an income stream from the portfolio.

Our chart shows the drawdown of an 80-20 portfolio invested in the S&P 500 and the Merrill Lynch Government and Corporate Bond Index and rebalanced annually. The drawdown is the peak-to-trough decline in a portfolio. The chart uses monthly data.

During the last big bear market an 80-20 portfolio would have suffered a peak to trough decline of over 40%. A 65 year old investor on the verge of retirement would have seen his retirement income future devastated by such a loss.

If you are in or nearing retirement, a good back of the envelope guide to a proper asset allocation is to invest your age in fixed income. You can also try your age minus 10. So if you are 65, you might consider putting 55-65% of your portfolio in fixed. This is of course a general guide and does not take into account your own financial situation or risk tolerance, but it can keep you out of trouble.
