Overly Optimistic Investors Face Potential Disappointment

Overly optimistic investor expectations of market returns may be a problem. To wit:

“While consumers are not very confident about the economy, they are highly optimistic about the stock market. In that same consumer confidence report from the Conference Board, the expectations for rising stock prices over the next 12 months are near the highest on record.

Of course, after a decade of 12% returns, why should they not be optimistic that the future will be much the same as the past? A good example came from a recent discussion with an individual wanting me to review the “financial plan” for their retirement goals. The plan was generated by one of the many “off the shelf” software packages that take all the inputs of income, assets, pensions, social security, etc., and then spits out assumptions of future asset values and drawdowns in retirement.

The problem is that the return assumptions were grossly flawed.

In the vast majority of these plans, the optimistic assumption is that individuals will have a rate of return of somewhere between 6-10% annually heading into retirement and 4-8% thereafter. The first major flaw in the plan is the “compounding” of annual returns over time, which does NOT happen.

“There is a massive difference between AVERAGE and ACTUAL returns on invested capital. Thus, in any given year, the impact of losses destroys the annualized “compounding” effect of money.

The chart below shows the difference between “actual” investment returns and “average” returns over time. See the problem? The purple-shaded area and the market price graph show “average” returns of 7% annually. However, the return gap in “actual returns,” due to periods of capital destruction, is quite significant.”
