Top 10 stocks and funds to invest in for 2011 circulate widely. It’s a recurring theme with a predictable storyline at the end of the year. The analyst: “Well, we indicated that stock XYZ should be the best performing one this year, and it should have been the case, but it has not for good reasons.” Analysts then borrow the “deus ex machina” plot device from the theatre (literally, “God out of the machine”), in which a seemingly inextricable problem is suddenly and abruptly solved with the unexpected intervention of some new character. For analysts this usually boils down to central banks not behaving like they should, politicians meddling with economics or misplaced optimism or pessimism of consumers or companies.
So unless the investing public suffers from collective amnesia with a yearly cycle, the real merit of predicting is not the prediction itself. Maybe it’s a form of mating game in the investment industry. The analyst, bank or mutual fund signals with his prediction to the investor that he knows the intricate details of financial markets, and is therefore fully in control of the risks attached to an investment. And once you’re in control of the risks, then there is actually no risk attached, is there? An elegant way to play into investor’s permanent desire for free investment lunches, an important theme in Meir Statman’s insightful book “What Investors Really Want”.
Maybe institutional investors and pension trustees should be given a second chance for better New Year’s resolutions. If they’re smart, they won’t focus on predictions, but on understanding why predictions continually fail, and how to benefit from this insight. This requires delving more into the beliefs behind the economic theories, and how they affect your investment decisions, the central theme of our recently published book Investment Beliefs. A Positive Approach to Institutional Investing. The problem at hand is quite simple. Despite all the research done and money spent in the financial industry, diverging views persist in economics and finance. A solid theory, broad dataset and sound research methods should be able to resolve ongoing debates and lead to accurate predictions. Economists and researchers surely put an enormous effort into research, but resolving debates tends to move slowly. Economics and finance are tough subjects to investigate. Why is this?
A historic perspective comes in handy. Investing theory and practice have developed dramatically over the past five decades, yet as Andrew Lo argues, there still is no objective framework around for viewing capital markets and deciding how to apply these insights for investment purposes. Active management, passive management, absolute return strategies – all are different views of capital markets that happily co-exist. Yet none can be pinpointed as the right one. Theories in investments and finance simply do not have the same degree of confidence as theories in physical sciences. The main theories have not been road tested; basic premises are not conclusive. For example, is there any agreement on whether financial market pricing is efficient; the basis for passive management? Research findings are inconclusive. There is an increasing amount of evidence on “anomalies”, unexplained gaps between predictions and realizations. However, no workable alternative for the underlying theory has been formulated that can be put to good use on a large scale. Moreover, few investors are actually able to exploit these “anomalies” and turn them into higher returns.
So in the meantime, students and investment managers learn that efficient pricing exists, but observe and act otherwise in practice. Believers in inefficient markets usually invest in what they perceive as undervalued stocks, sectors or assets, and do appreciate market-timing. In a brilliant stroke of marketing, they have labeled themselves as “active” managers, ideally positioned for investors who want to be in control and want to win. Believers in efficient markets on the other hand focus on buying the index against the lowest costs possible: costs are after all a certain drag on your returns, while the free investment lunches pictured by the active managers have yet to materialize.
This discussion suggests that the smart, rational money is on passive investing. The reality is the other way around. The overwhelming share of equities is invested by active managers. Our experience is however that pension funds would make fundamentally different choices if they were aware of the uncertainties behind the economic and finance theories – after all, it boils down to what you believe in. We call this investment beliefs: an explicit view on how to interpret, and approach a debate in the financial markets. We covered active versus passive management as a noteworthy investment belief, but there are many other beliefs out there: on sustainability, risk premium, investment horizon, risk management- to name a few.
Investors simply have to deal with the fact that many debates never really reach a firm conclusion and keep haunting them. Proponents of active management have just as much ammunition in the form of anecdotal evidence or research to prove their case to sympathizers of passive management as the other way round. There is no single objective truth in the financial markets, just an accumulation of learning by doing and adapting to new realities. Investment beliefs address this uncertainty and make it manageable – not predictable.
So, chances are that the predictions will once again miss the mark. This shouldn’t worry investors, and certainly not prevent us from filling out the sweepstakes. The process of arriving at a prediction might well be more important than the prediction itself. Wouldn’t that be a great way to actually realize a New Year’s resolution?

Think of an investor who had a $2 million portfolio in October 2007, $1 million in bonds and $1 million in stocks. Visit him again in February 2009 when his bonds are still worth $1 million but his stocks are worth only $500,000. What should he do now? Should he re-balance his portfolio? And, if so, how should he re-balance?
The initial portfolio was a 50/50 stock/bond portfolio and the standard advice is to re-balance back to a 50/50 portfolio by selling $250,000 worth of bonds and using the proceeds to buy $250,000 of stocks. This advice flows from two distinct reasons, one related to risk tolerance and the other to expected returns.
The risk tolerance reason is that an investor who has chosen a 50/50 portfolio has declared that his risk tolerance corresponds to an optimal 50/50 portfolio. The February 2009 portfolio is a 33.3/66.7 stock/bond portfolio, so it is sub-optimal. The portfolio can be made optimal again by restoring it to its 50/50 proportions.
The expected returns reason is that securities returns tend to be mean-reverting, so it is likely that the returns of stocks would be high relative to their long-term mean following periods where their returns were low relative to their mean, and the same is true for bonds. If our world of returns is a mean-reverting world then investors benefits by buying stocks just before their returns are especially high and selling them just before their returns are especially low. In a recent exchange of letters to the editor of the Financial Analysts Journal, William Bernstein argued that our world is a mean-reverting world while William Sharpe argued that it is not clear that this is our world.
The re-balancing answer of behavioral portfolio theory is quite different from these two answers. The investor with a $2 million portfolio chose to invest $1 million in stocks and $1 million in bonds because he has two distinct goals reflected in two mental accounts or “buckets.” Being-rich is one goal, and that is the purpose of the $1 million in stocks. Not-being-poor is the other goal, and that is the purpose of the $1 million in bonds. We can think of the not-being-poor goal as the goal of retirement at a basic level of comfort. We can think of the being-rich goal as the goal of enjoying luxuries in retirement or leaving a substantial bequest to children or charity.
A “behavioral investor” might well object to selling bonds from his not-being-poor mental account because the proceeds of such sales might be lost if invested in stocks, diminishing his basic level of comfort in retirement. Our investor has good reason to refuse the usual re-balancing advice and financial advisers should listen to him.
