With the end of the year fast approaching, it is an excellent time to discuss the concept of rebalancing one’s investment portfolio.  The simplest definition of rebalancing is the periodic reallocation of an investment portfolio back to the original percentages desired.  The fluctuations of the financial markets over time will inevitably alter the amount of exposure in one’s investment portfolio to different types of assets.  The jargon in the financial services industry is your asset allocation

These changes may cause the portfolio to be suboptimal given an individual investor’s financial goals and tolerance for risk.  Knowing about rebalancing is so important because it is one of the most effective ways to eliminate, or at least reduce, the emotions surrounding investment decisions that affect even professional investors.  Additionally, numerous academic studies have concluded that 85% of the overall return of an investment portfolio comes from asset allocation.

I published a three-part series of articles to define and explain the various nuances of rebalancing an individual investor’s investment portfolio several years ago.  However, I thought that it would be a great idea to bring it back as an updated version because the end of the year is fast approaching.  The first article covers the definition of rebalancing in its entirety.  Furthermore, the article looks at an illustration of how rebalancing works in the real world.  It offers an introduction to this important investing tool.  The link to the complete article can be found here:


The second article discusses a unique way to get assistance with rebalancing an investment portfolio.  Many of the largest asset managers in the financial services industry, such as Vanguard, Fidelity, and T Rowe Price, offer life cycle or target date mutual funds.  These mutual funds have a predefined year that the individual investor intends to retire.  Moreover, the combination of assets in the mutual fund is structured to change over time and become less risky as the target date approaches.

Since these mutual funds report their holdings on a periodic basis, any individual investor is able to replicate the strategy for free.  Plus, another feature is that an individual investor can be more conservative or aggressive than his/her age warrants according to the mutual fund family’s calculations.  The individual investor is able to pick a target date closer than the endpoint (i.e. more conservative) or pick a target date later than the endpoint (i.e. more aggressive).  For a more comprehensive discussion of this facet of rebalancing an investment portfolio follow this link:


The third and final article discusses the most advanced feature of rebalancing utilized by a subset of individual investors.  The investing strategy is referred to as dynamic rebalancing in most investment circles.  Dynamic rebalancing follows the general tenets of rebalancing.  However, it allows the individual investor to exercise more flexibility during the rebalancing process of the investment portfolio.  Essentially the individual investor determines bands or ranges of acceptable exposures to asset classes or components within the investment portfolio.

For example, a lower bound and upper bound for the asset allocation percentage to stocks is set.  The individual investor is free to allocate monies to stocks no less than the lower bound and no more than the upper bound.  Note that the bands or ranges are normally fairly tight and applies to the subcomponents of the investment portfolio, such as small cap stocks, emerging market stocks, international bonds, and so forth.  To learn more about this fairly complex aspect of rebalancing follow this link:


The articles above capture the vast majority of information individual investors need to know about rebalancing an investment portfolio.  It is good to get a head start on learning about or reviewing this topic prior to the end of the year.  The reason is that most rebalancing plans utilize the end of the calendar year as the periodic adjustment timeframe.
