Guest post, Rob Bennett
Investing is both an art and a science. There are passionate supporters of a wide range of investing methodologies and the research can be tweaked to support various approaches. From passive investors to frequent traders, myths about investing abound. But these six investing myths just might cause you to rethink your stock and bond market beliefs.

Passive investors who champion the index fund investing approach, believe that it’s difficult if not impossible to beat the long term market averages. For investors that consider investment valuations, following are six investing myths to consider.
Valuation Informed Indexing Approach
Mr. Bennett advocates valuation-Informed Indexing. This strategy calls for the investor to increase his stock allocation when prices are low and to decrease his allocation when prices are high. The concept is rooted in the research of Yale Economics Professor Robert Shiller, who found that, contrary to the widespread belief that market timing doesn’t work, long-term returns are predictably poor starting from times of high valuations.
6 Investing Myths
Here are six myths about investing that are viewed as truths by Buy-and-Holders but as dangerous investing myths by those who acknowledge Nobel Prize winner, Robert J. Shiller’s research findings.
Investing Myth 1 – Market Timing Doesn’t Work
Buy-and-Holders believe that the market is efficient; that is, all information known to affect the market price is incorporated into it at all times. It follows that market timing cannot work; no one can effectively guess how unforeseeable events are going to play out.
Valuation-Informed Indexers believe that investor emotions are the primary influence on prices in the short term and that economic realities become dominant only after the passage of 10 years or so. If this is so, long-term returns are highly predictable (prices move in the direction of fair value). Under the new understanding of how stock investing works, timing is not only possible but required; investors who fail to change their stock allocations in response to big price shifts thereby permit their risk levels to get wildly out of whack.
Barb’s comment; Actually, maintaining a constant asset allocation will do this for you. When one asset class becomes overvalued, you will rebalance by either selling the overvalued asset class or putting future cash into lower valued assets. So, a buy-and holder who rebalances might be considered a market timer as well.
Investing Myth 2 – Economic Developments Cause Stock Price Changes
Did you know that Shiller predicted a former economic crisis? So did Robert Arnott. So did Andew Smithers. So did every stock analyst who takes Shiller’s findings seriously. How did they perform this magic feat?
Valuation-Informed Indexers don’t believe that it is economic developments that cause stock price changes but that it is stock price changes that cause economic developments. The market was overpriced by $12 trillion in 2000. The inevitable return to fair value was going to cause a loss of that amount of buying power from our consumer economy. The crisis became unavoidable once we permitted the bull market to get so out of control.
Barb’s comment; Markets can remain overvalued for very long periods of time.
“The stock market can remain irrational longer than you can remain solvent.”
~John Maynard Keynes
Investing Myth 3 – The Safe Withdrawal Rate Is a Constant Number
Financial planners use the concept of the “safe withdrawal rate” to tell us how to structure our retirement plans. The idea is to use the historical return data to determine what withdrawal rate would work even in a worst-case scenario. The conventional studies are rooted in the pre-Shiller research and thus do not consider the effect of the valuation level that applies on the day the retirement begins. Studies that do consider valuations come to wildly different conclusions as to what is safe. In the event that Shiller is right, millions of middle-class people will be experiencing failed retirements in days to come.
Investing Myth 4 – Stocks Are More Risky Than Bonds
This has been the conventional wisdom for a long, long time. But risk is uncertainty. If Shiller is right that long-term returns are highly predictable, stocks are not nearly as risky as we have long believed them to be. If Shiller is right, stocks are a high-risk asset class only for those who don’t take valuations into consideration when setting their stock allocations.
Barb’s comment: Modern Portfolio research defines risk as volatility. In other words, how much your asset value moves up and down in price. In general, stocks are more volatile than bonds, although over the long term they have offered much higher returns than bonds. Warren Buffett suggests that risk is running out of money in retirement.
Investing Myth 5 – Super-Safe Asset Classes Are a Poor Choice for Long-Term Investors
The conventional wisdom is that stocks are always best for the long -term investor and super-safe asset classes never provide returns high enough to finance a comfortable middle-class retirement. But a regression analysis of the historical return data showed that at the prices they were selling at in 2000 stocks were likely to provide an annualized return of something in the neighborhood of a negative 1 percent real. In contrast, Treasury Inflation-Protected Securities (TIPS) were at the time paying 4 percent real. That’s a return differential of 5 percentage points per year for 10 years running — a total shortfall for the stock investor of 50 percent of his initial portfolio value.
Barb’s comment: During the first decade of the millennium bond returns outperformed those of stocks.
Investing Myth 6 – Stocks Are a Good Buy in the Wake of a Price Crash
Whether a stock is a good buy in the wake of a crash depends on how much the stock values fall and what their relative values are. For example, after the bursting of the dot.com tech bubble in 2000, stocks fell 9%, 11% and 22% in 2000, 2001, and 2002. Understanding stock valuations would have helped you determine whether stocks were in fact a good value or not. In many cases, after a major market decline, stocks become for fairly or undervalued, but not always. That said, trying to pick the bottom when investing is nearly impossible.
Barb’s comment: Regular investing with dollar cost averaging will lead to buying more shares a lower prices and fewer when prices are high.
