Or will it?

In light of meager returns on most asset classes, many financial advisors now caution that their clients need to scrutinize their rate of spending as carefully as the performance of their portfolios. "I don’t care if a client has a million dollars in net worth, a hundred million or a billion net worth, you have to look at their outflows," says Tom Zanecchia, president of Denver-based Wealth Management Consultants. He adds, "More often than not, as people acquire more wealth they are not in fact richer, because their spending goes up more than their wealth has."

TOP VIEW: Experts caution that affluent families’ rate of spending should be analyzed with the same rigor as the performance of their portfolios. Single-digit equity market returns will affect the spending rates that fixed pools of assets can sustain. Advisors say that now is a crucial time for those living off such pools to determine if their current rate of spending will ultimately erode their overall wealth.

According to a recent study by JPMorgan Private Bank, Wealth Preservation: The Rate at Which You Spend Matters–Even More Than Your Asset Allocation, an investor who lives purely off a fixed pool of assets and annually spends just 5 percent of his net wealth has a one-in-three chance of suffering a 20 percent reduction in his real wealth over the course of two decades. "Over the long haul, we would say that spending is more important than, or as important as, asset allocation," says Tricia Stewart, author of the report and managing director with JPMorgan Private Bank in New York. "And we would recommend that our clients maintain their spending at about an annual 3 percent or 4 percent level," she adds. "You can’t be spending 5 percent or 7 percent of a fixed pool of assets every year and still expect to meet your lifestyle goals."

Stewart and her team have concluded that equity market volatility and the expectation of single-digit returns for the foreseeable future will affect the spending rates that fixed pools of assets can sustain. Now, they argue, is the crucial time for those living off such pools to determine if their current rate of spending is eroding their real, overall wealth.

To illustrate the problem, the bank’s analysts looked at how equity and fixed income market returns affected the performance of a fixed investment pool on an inflation-adjusted basis, assuming a rate of withdrawal of 5 percent per year, from 1926 through 2004. Contrary to popular opinion, they found that the way a portfolio is split between equities and fixed income makes very little difference to long-term wealth preservation. Figure 1 illustrates the annual performance of three different portfolios: a 70 percent allocation to equities, a 50 percent allocation and, finally, a 30 percent allocation.

In the context of a 20-year time frame (a typical investment horizon for a private client that would include, for example, the inflationary 1970s, when equity markets underperformed), the portfolios’ asset allocation had practically no effect on dampening wealth erosion. All three portfolios would have lost around 50 percent of their value. "We found that although asset allocation clearly helps you in a bull market, it doesn’t bail you out when markets are performing poorly," Stewart says. "The amount the investor had in equities was, within reason, almost irrelevant, as long as he had some sort of mix."

JPMorgan extended the analysis to look at what would happen to a static portfolio with a 70 percent allocation to equities with hypothetical annual spending (withdrawal) rates of 3 percent, 5 percent and 7 percent over the same time period. Figure 2 shows how even small variations in the spending rate leads to more pronounced differences in portfolio value compared to different asset allocations. Their conclusion is clear: Asset allocation cannot compensate for spending blindly.
