Getting real about investment returns

Financially Speaking
John Spoto

---- — Despite two steep stock market declines in the last 13 years, baby boomers who are now retiring in droves have grown accustomed to earning strong returns on their savings and investments. Over the last 30 years the stock and bond markets returned roughly 10 percent and 6 percent respectively before inflation and about 7 percent and 3 percent in real (after inflation) terms.

Although we are repeatedly cautioned that “past performance does not guarantee future results,” research in the field of behavioral finance has demonstrated that even for sophisticated investors, past experience shapes our outlook of the future. In other words, in the context of the financial markets, “the good times should continue to roll.” That perspective, however, doesn’t square with the realities of today’s investing environment.

Investors worldwide are still grappling with the effects of the deepest economic downturn since the Great Depression. In an effort to stimulate the economy the Federal Reserve and central banks around the world embarked on an aggressive strategy to drive down interest rates to near historic levels.

The result is that we have transitioned to a world of low interest rates that most experts anticipate will continue for the foreseeable future. This presents a challenge for investors seeking to preserve and grow their nest eggs for two reasons.

First, with bonds generating miniscule yields, extrapolating the high bond returns of the last 30 years into the future would be pure fantasy. Second, because both history and basic financial principles teach us that equity returns are affected by interest rates; low rates also have important implications for stock returns.

The dilemma faced by every investor from institutional fund managers to average individuals is that projecting future investment returns with certainty is unrealistic because we don’t know precisely how the future will unfold.

However, in order to make intelligent decisions including how much to allocate to the different asset classes, how much we can spend today, and how much we need to save to fund future goals, we need a projection of the markets’ long-term performance.

In basic terms, the more optimistic the return assumption, the less we need to save in order to accumulate a desired amount of money.

Conversely the more conservative the assumption the more we’ll need to set aside to reach that goal. So, how do we construct reasonable return expectations for U.S. bonds and stocks going forward? Fortunately we have guidelines that have proven helpful in the past, particularly for bond returns, and from these we can estimate equity returns.

Since most of the returns that bond investors earn come from the yield (the interest the bond is paying), a good predictor of future bond returns is the current yield. A 10-year Treasury bond currently offers a yield of about 3 percent, so this would be a reasonable return to expect for the next 10 years.

Although stock returns are unpredictable in the short-run, when investment experts apply metrics that have demonstrated predictive value in the past including the relationship between stock market returns and U.S. government bonds, expected long-term stock returns hover around 6 percent

When we adjust for a projected inflation rate of about 2 percent, we arrive at real returns close to zero for bonds and about 3 to 4 percent for stocks. To carry out the arithmetic further, this means an investor with a portfolio of 50 percent stocks and 50 percent bonds should be targeting an overall assumed return of about 5 percent before inflation and 2 percent after inflation. In other words, less than half the return we have enjoyed historically.

This means that many of the return assumptions built into the financial plans of individual investorsare overly optimistic. This may result in large funding shortfalls posing serious problems, especially for those trying to determine how much to save for retirement and once in retirement how much to spend without running out of money prematurely

Next week we’ll talk about some sensible strategies investors can employ to minimize the effect of low investment returns on their financial goals.
