Protecting Your Retirement Assets
Risk of ruin in finance can mean the probability of bankruptcy or, in the case of a retiree, outliving one's assets. A retiree who can generate all the annual income he needs from a cash/fixed income portfolio doesn't have to worry about risk of ruin. But even a bond portfolio faces reinvestment risk if a higher interest-paying bond matures when interest rates are lower. At that point, buying a new bond won't generate the same income. That may pinch the retiree, but it won't ruin him or her.

However, a retiree's real risk of ruin comes from stock market volatility and the retiree's need to liquidate assets periodically for income. Withdrawals taken during down or flat market cycles create a risk of ruin just like a string of losing trades for an active trader.
The way to avoid risk of ruin is the same for the retiree and the trader: start with enough capital to withstand a string of losses. To do so, you have to estimate the probability of future returns and the rate of inflation. Read on to find how.
The Sequence Of Returns
The greatest danger for someone in or planning on retirement is relying on this scenario - using one period of market performance as a guide. For anyone liquidating assets periodically, what's important isn't just the rate of return, it's the sequence of returns.
For 17 years, beginning in 1966, the market was flat and had the highest inflation on record. Few if any financial advisors or stockbrokers use that period for their illustrations. According to William Bernstein's book "Four Pillars of Investing" (2002) the reason is simple: No asset allocation avoids bankruptcy when a 4% withdrawal rate is applied to a $1 million portfolio using returns from that time period.
The 4% withdrawal rate used by many financial advisors is no guarantee. Illustrations using an average annual return, even for a long period of time, are especially dangerous. Actual annual returns are hardly ever average. In 54 of the 82 years between 1926 and 2007, the Standard & Poor's 500 Index (S&P 500) performance was either a loss or a gain of more than 20%. In other words, almost 66% of the time, the index returned better or worse than a return of between 0% and 20%. Only one-third of the time did the index performance fall within the range of an "average" 10% return (0% to 20%).
An average annual return is irrelevant. It's the sequence of returns that's important.
For example, over the 17-year period (1987-2003), the S&P 500's average return was 13.47%. It doesn't make any difference if we look at the returns from 1987 to 2003 or from 2003 to 1987.
But when taking withdrawals, the sequence of returns makes all the difference. The same initial capital, the same withdrawal amount, the same returns - but a different sequence produces dramatically different results.
For a $100,000 portfolio taking $10,000 a year adjusted for 4% inflation over those 17 years, the difference is a remaining balance of $76,629 to a deficit of $187,606. The following table illustrates the dramatic difference in return that occurs by inverting the rates and putting 2003's performance first and 1987's last.
|Year||Portfolio Value - Beginning of Year||Value After $10,000 Inflation-Adjusted Withdrawal||Rate of Return||Portfolio Value -Year End|
|Average Annual Return:||13.47%|
|Year||Portfolio Value - Beginning of Year||Value After $10,000 Inflation Adjusted Withdrawal||Rate of Return||Portfolio Value -Year End|
|Average Annual Return:||13.47%|
What's striking about this result is that three years of negative returns at the beginning of the withdrawal sequence completely negate the positive returns of the best bull market anyone in retirement is likely to experience in the future: Performance for 1995-1999 was +37.6%, +23.0%, +33.4%, +28.6% and +21.0% respectively. It is unlikely that we will see that kind of winning streak again for quite some time.
Regardless of those four consecutive years of great returns, the portfolio drops to $4,348 after the tenth year's withdrawal – the point of ruin.
Outliving Your Savings
Clearly, a key issue for a retiree is the condition of the market at or very early in retirement. If it happens prior to retirement, a delay of a year or two may dramatically reduce the risk of ruin. If it happens in retirement, some action is required, such as part-time employment or reducing one's cost of living.
Risk of ruin brings to the forefront the following concepts that every investor should be thinking about before making any decisions about retirement.
Risk of ruin can be an antidote for the rules that guide investors during the wealth accumulation phase. For a long-term investor, market risk is accepted as a given, because the long-term positive performance of the market takes care of that problem. But an investor liquidating principal can't depend on the long term. As such, the retiree has to know, for any given year, the maximum market loss that can be absorbed to still have money to live on in the coming year.
