The value of the assets changes per the returns they generate. Accordingly, the weightage of the assets differs. Depending on the current weight of the assets, the investors require categorizing them under the portfolio labels best suited for the respective financial instruments per the investment plan. This, in turn, helps balance investor portfolios as per the changing market scenario.

Key Takeaways

  • Portfolio rebalancing is a reallocation of the weight of portfolio assets. It includes buying and selling existing assets either fully or partially from time to time to maintain the desired level of return.
  • Rebalancing can be industry or sector-specific or in combination.
  • The portfolio assets can be a mix of bonds, equity, and other stocks depending on the investor’s appetite for risk and return and movement and value of stocks.
  • Portfolio rebalancing can be time-based, threshold-based, or risk-based, depending on the investors’ approach and suitability.

Portfolio Rebalancing Explained

Portfolio rebalancing keeps investor profiles balanced. Given the frequent fluctuations in the market, individuals must have a provision for adjusting their portfolios to ensure minimum risks and maximum profits on any investment. In addition, the rebalancing process enables them to reallocate their assets, so the holders do not incur losses.

Rebalancing is done to ensure investors do not depend on the performance of a single investment. It gives investors a chance to have a diversified portfolio. The scattered investments make people control risks by not depending on the success or failure of a single portfolio.

The portfolio is rebalanced from time to time so that investors can gain maximum return on investment. Wealth managers, mutual funds providers, and investment bankers who handle portfolios involving a huge amount of money pay careful consideration to rebalance to deliver the expected return level throughout the investment tenure.

The investor or fund manager shuffles the stocks in the portfolio to maintain the desired return and risk level. This shuffling is done after careful stock analysis, facilitated by a lot of decision-making and experience. The portfolio is based on an investor’s risk appetite. For example, a risk-averse investor (low-risk taker) invests more in bonds than in equity. The reason is that bonds deliver fixed and periodic interest rates and volatile equity. In such a case, the investor might invest around 70%-80% in bonds and balance 30%-20% in equity.

Similarly, an investor who wants a high return and has a good risk appetite will invest less in bonds and more in inequity. In such a case, the scenario is reversed, and they invest 70%-80% in equity and the remaining 30%-20% in bonds. Again, an investor who wants an average return will invest 50% each in bonds and stocks.

Time-based rebalancing refers to balancing portfolios at specific intervals based on status, as revealed through regular monitoring. Though it is an effective means of determining ways to rebalance, overdoing the same could hamper the returns. Thus, time-based rebalancing must be done carefully.

The threshold-based portfolio enables investors to reallocate asset classes to have a mixed or diverse portfolio. This, in turn, ensures individuals adopting the strategy reap maximum profits as they do not have to depend on a single investment. Instead, they can have diversified portfolios for profits and risk control.

The risk-based rebalancing lets investors rebalance portfolios if they realize the risks would increase. In short, they can choose to diversify their investments to tackle the losses wisely. Learning these practices makes investors understand the portfolio rebalancing meaning better.


Let us consider the following portfolio rebalancing example to understand the concept better:

A Mutual funds manager pools in $10m from individual investors, and diversifies the risk in the portfolio by investing 50% in equity and 50% in bonds. The manager also diversifies risks further across different sectors in the percentage below.

Real Estate10%
Oil and Gas15%
Information Technology10%

The fund manager chooses to review the performance regularly and decide to rebalance the portfolio monthly, quarterly, or yearly per the suitability.
