What is investment portfolio rebalancing and how to do it

Financial markets are constantly moving. Asset prices change, portfolio relationships distort. The initial structure no longer reflects the original goals. It is in these moments that the key management mechanism is activated – portfolio rebalancing. The process of adjusting assets maintains a balance between return and risk. Without regular review, the capital structure deviates from the planned trajectory, reducing the effectiveness of the strategy.

Essence and goals: what is portfolio rebalancing

Adjusting an investment portfolio involves redistributing shares between assets to restore target distribution parameters.

Why the need arises:

1. The growth of one group of assets increases its share above the norm.
2. The decrease in the value of another group leads to imbalance.
3. The current structure does not correspond to the changed risk level.

Portfolio rebalancing restores the initially embedded investment logic, reduces imbalances, maintains control over returns and volatility.

How to conduct portfolio rebalancing: action algorithm

The correct procedure starts not with emotions, but with numbers and strategic analysis. Basic steps:

1. Determine current asset allocations. Calculate how many percent each asset class occupies in the actual portfolio structure.

2. Compare with the target model. Check the deviation from the planned ratio: stocks, bonds, gold, funds, real estate, etc.

3. Calculate the necessary volume of redistribution. Determine how much to sell or buy to restore proportions.

4. Assess the market and choose the entry point. Consider liquidity, commissions, taxation.

5. Fix the structure and set a time reference for the next review

Portfolio rebalancing requires discipline and cold logic. Only such an approach ensures the preservation of the investment trajectory.

Frequency of portfolio rebalancing: how to choose the frequency

The choice of interval depends on the strategy, asset volatility, and investor’s goals. Frequent correction enhances control but increases costs. Rare correction reduces accuracy and increases risk.

Main formats:

1. Calendar rebalancing. Carried out at equal time intervals: quarterly, semi-annually, annually.

2. Threshold rebalancing. Assets are adjusted when the share deviates from the target by a certain percentage (e.g., 5–10%).

Situational portfolio rebalancing: unplanned intervention

Sometimes the market situation requires immediate intervention. The calendar and percentages lose relevance – it’s time for situational rebalancing.

Reasons for unplanned correction:

• significant price changes in key assets;

• change in investment goal (approaching deadline, change of strategy);

• change in economic conditions (crisis, geopolitics);

• increase in volatility or sharp decrease in returns.

Example: portfolio rebalancing in practice

Initial structure:

• stocks — 60%;

• bonds — 30%;

• gold — 10%.

After 6 months:

• stocks — 72% (significant growth);

• bonds — 22%;

• gold — 6%.

Actions:

• sell some stocks, buy bonds and gold;

• restore proportions to the original.

Portfolio rebalancing allows you to lock in profits from overheated assets and add capital to undervalued directions.

When reviewing an investment portfolio becomes mandatory

Some signals require immediate action. Delay results in lower returns or increased risk.

Reasons for review:

• change in investor’s life stage (retirement, birth of a child);

• change in investment horizon;

• rise in interest rates, inflation, or decrease in global liquidity;

• radical market trends;

• sharp imbalance between expected and actual returns.

Types of assets involved in rebalancing

Key asset classes:

1. Stocks. Provide capital growth but are characterized by high volatility.

2. Bonds. Add stability and fixed income. Often act as a counterbalance.

3. Precious metals (gold, silver). Used as protection against inflation and currency instability.

4. Funds (ETFs, index funds). Allow diversifying investments in one click.

5. Real estate. Provides a real asset, stable rental income, low correlation with the stock market.

6. Cryptocurrencies. High potential returns and risk. Suitable only for a certain portion of the portfolio.

7. Cash and short-term instruments. Create a liquidity cushion and protect against losses in crisis phases.

Portfolio rebalancing works more efficiently with a clear understanding of the function of each asset type.

Mistakes in portfolio rebalancing and how to avoid them

Even with a clear investment plan, investors make actions that can undermine the effectiveness of the strategy. Mistakes occur either due to emotional pressure or technical incompetence. To ensure that portfolio rebalancing fulfills its tasks, it is necessary to eliminate typical miscalculations in advance:

1. Emotional decisions. Panic on a decline or euphoria at a peak provoke unfounded transactions. Instead of preserving the investment structure, the investor chases short-term returns. This disrupts risk management logic and reduces portfolio stability.
2. Ignoring commissions and taxes. Mechanical selling and buying of assets without calculating costs leads to a loss of part of the income. When rebalancing at short intervals, it is especially important to consider commissions, spreads, and capital gains tax.
3. Lack of strategy. Rebalancing without a clearly defined portfolio model turns into chaos. Without pre-selected proportions, an acceptable deviation range, and review rules, it is impossible to maintain a systematic approach.
4. Violation of investment logic. Often, after the share of a particular asset increases, the investor leaves it hoping for the trend to continue. This contradicts the principle of selling overvalued assets and buying undervalued ones. Violating logic disrupts goals and structure.

Connection with investment policy: not just correction, but a strategic tool

Financial goals require specific parameters: risk level, expected return, investment horizon. All this is formalized in the investment policy. Portfolio rebalancing acts as a tool that aligns practice with this document.

What ensures consistency:

• maintaining the specified asset share depending on goals (accumulation, capitalization, passive income);

• reducing the risk of deviations from the planned trajectory;

• controlling volatility without losing potential returns.

If the portfolio structure deviates from the logic of the investment policy, the strategy loses its meaning. Only regular redistribution can maintain focus on the goal.

Impact on risk and return

Changing the asset structure directly affects portfolio behavior. Skewing towards stocks increases volatility, towards bonds – reduces returns. Maintaining balance allows controlling both.

Main impact mechanisms:

• Redistribution reduces the risk of portfolio overheating;

• Realizing profits protects against a collapse of overheated assets;
