Do not wait to be right


In order to "become right," some investors will stand by their predictions despite a stock or the market going the opposite way, hoping to be proven correct. Ned Davis called this the curse of "being right rather than making money."There are only two kinds of predictions that have some value to investors: One is probability-based, and the other is risk-based. As long as you apply the same rules -- no one knows the future, they are subject to revision and should not be taken as gospel -- then these are sometimes worth considering.Probability assessments are typically based upon historical comparisons of prior markets with similar characteristics: The more variables that align, the higher the likelihood that a given scenario plays out in a similar fashion. They are of this variety: In the past, when X, Y and Z all happened together, then we expect that A is most likely, then B is possible, while C is the least likely.That doesn't mean A will happen or C cannot -- only that there's a specific probability of these events occurring out of the millions of ways the future might unfold. Whether any particular scenario plays out is determined by how the countless variables interact over time.

Looking at the future in terms of various probabilities is a productive way to position assets and manage risk. Why? If your expectations for the future recognize that this is but one possible outcome, then you are more likely to consider and plan for other contingencies. It builds in an expectation that other scenarios can and will occur.
