The stock market was down again today, adding to a string of five consecutive weekly losses. A weak jobs report on Friday capped evidence of a slowing economy seen from various reports these last several weeks. Softening US economic data coupled with renewed concern with international debt issues have made investors nervous and quick to move to the sideline. The S&P 500 is down about 5.5% since the end of April, erasing most of the 6.2% return seen year to date prior to this pullback. Notably (according to the talking heads), this is the worst 5 week showing since mid 2004. The question is, at this juncture, should we buy, hold or sell strategic positions? What can we discern from this recent action that is usable to make decisions that will benefit us going forward?
I received an MBA in finance in 1986 and started my investment career that year. As such, I have been in the investment business for about 25 years and counting. As a student, I learned about efficient markets and the cons of trying to outsmart or outguess the market, but then I was hired as a securities analyst and was paid for my opinion. In the bull market years of the 1990’s, we picked winning stocks with impunity. Interestingly enough, it got a lot harder to pick winners in the early 2000’s. Looking back, I see that the market’s underlying direction had a lot to do with our perceived skill or lack thereof, rather than much in the way of unique insights.
These last nine years, I have been managing portfolios for individuals and small company profit sharing plans. I have worked hard to add value by moving securities around the asset allocation board, either to generate incremental returns or in an effort to mitigate loss. Sometimes moving around helped, but other times it didn’t. As a Registered Investment Advisor, I owe my client’s a fiduciary responsibility to act in their best interest. Last year I decided it was time to review the body of evidence and refresh my opinion on the age old debate between Market Efficiency and Market Timing. While the debate rages on, the data indicates there is no debate.
The body of evidence strongly suggests that markets very quickly discount new information and which way the market is going to go next depends on the next piece of information, and so on and so on. Guessing which way the market is going to go next is well, guesswork. We can only know whether or not we should respond to this current 5.5% pullback by buying or selling with hindsight as a guide. Undoubtedly some market “professional” will guess correctly that person will be paraded out on all the talk show to tout their market prowess, until the next prognosticator comes along. But they in all likelihood just got lucky. Statistically, it takes 63 years to separate skill from luck at the 95th percentile.
Surely, some people are sharp enough to add value over a “buy and hold” strategy, but the key is to add value net of fees, transaction costs and taxes. Many peer reviewed studies show that “time in the market” actually outperforms “timing the market”, net of costs. The only observation that is statistically noteworthy (using multi-linear regression for you geeks out there) is that over the longer term (1927-2010) the stock market outperforms the Treasury bond market by about 8.0% per year, on average. Beyond that, small capitalization stocks outperform large capitalization stocks by an average of 3.75% per year and value (low price to book) stocks outperform growth (high price to book) stocks by an average of 4.9% per year. This phenomenon has persisted over all 20 year periods and over the vast majority of 10 year periods.
Beyond these investment “risk factors”, there is NO statistical evidence that professionals, much less average investors add value by moving pieces around the board. In numerous academic studies, no more top decile performers in any 3, 5 or 10 year periods were again top decile performers in subsequent 3, 5 or 10 year periods than would be expected by pure chance.
The reason professional money managers continue to try to beat the market in spite of all the evidence that it is a loser’s game boils down to one reason and one reason only. They are paid to play the game by individual and institutional investors. Hope springs eternal. Wouldn’t it be great to pick the winners and avoid the losers. It is everyone’s greatest hope. It has surely been mine. However, honest reflection begs to differ.
What we know with certainty is that fees, transaction costs and taxes are drags on performance. Rather than view the market as an enemy to conquer, the smart money says we should view the market as a friend, to be embraced and ridden for all it is worth. Establish your strategic asset allocation that is consistent with your goals, time horizon and ability to sleep at night. Invest based on your personal goals. That is, based on when you expect to spend the money: Long term investing for long term needs. When markets invariably tumble and your allocation percentages stray, rebalance and buy more of the asset classes that have fallen. When the market invariably recovers (and it always does), rebalance and sell the asset classes that rose.
Leave the market timing to those that don’t need their money. You’ve worked too hard for yours.
