Portfolio Management: Introduction, Types, and Strategies

What Is Portfolio Management?

Portfolio management involves the skillful and systematic process of choosing and supervising a collection of investments that align with the specific long-term financial goals and risk appetite of an individual, a corporation, or an organization.

While some individuals prefer to personally handle their investment portfolio management, this undertaking necessitates a fundamental comprehension of the essential components of constructing and maintaining a successful portfolio. These components include strategic asset allocation, the practice of determining the ideal distribution of investments across various asset classes, such as stocks, bonds, and cash, taking into account factors such as risk tolerance and investment objectives. Additionally, diversification plays a crucial role by spreading investments across different securities within each asset class to mitigate the risk associated with any single investment. Lastly, regular portfolio rebalancing is essential to ensure the portfolio’s alignment with the desired asset allocation and to adapt to changing market conditions.

By acquiring a strong grasp of these fundamental concepts and implementing effective portfolio management strategies, individuals can aim for enhanced control and achievement in managing their investment portfolios.


  • Investment portfolio management involves building and overseeing a selection of assets such as stocks, bonds, and cash that meet the long-term financial goals and risk tolerance of an investor.
  • Active portfolio management requires strategically buying and selling stocks and other assets in an effort to beat the performance of the broader market.
  • Passive portfolio management seeks to match the returns of the market by mimicking the makeup of an index or indexes.
  • Investors can implement strategies to aggressively pursue profits, conservatively attempt to preserve capital, or a blend of both.
  • Portfolio management requires clear long-term goals, clarity from the IRS on tax legislation changes, understanding of investor risk tolerance, and a willingness to study investment options.

Understanding Portfolio Management

Professional portfolio managers, who are licensed and experienced, play a crucial role in managing portfolios on behalf of clients. However, individuals also have the option to take charge of building and overseeing their own investment portfolios. In both scenarios, the primary objective of the portfolio manager is to optimize the expected return on investments while maintaining an acceptable level of risk exposure.

Effective portfolio management entails skillfully evaluating the strengths and weaknesses, as well as identifying opportunities and potential risks, across the entire range of investment options. This involves making strategic decisions that involve trade-offs, such as choosing between debt and equity investments, domestic and international markets, and balancing growth potential with safety considerations.

The portfolio manager must carefully assess various factors, including market conditions, economic trends, company fundamentals, and financial indicators, to make informed investment choices. They analyze available data, conduct thorough research, and apply their expertise to construct well-diversified portfolios that align with the clients’ objectives and risk tolerance.

The decision-making process involves weighing the potential benefits and drawbacks of different investment opportunities. For instance, they may evaluate the trade-off between the income stability of debt instruments and the growth potential of equity investments. They also consider the advantages and disadvantages of investing in domestic markets versus international markets, taking into account factors like currency risk and geopolitical influences.

Furthermore, portfolio managers need to strike a balance between pursuing growth opportunities and preserving capital. They must carefully assess the risk-return trade-off inherent in each investment decision, aiming to generate attractive returns while managing the associated risks within acceptable limits.

In summary, portfolio management, whether conducted by professionals or individuals, requires a comprehensive evaluation of investment options and a disciplined approach to decision-making. It involves analyzing various trade-offs, such as debt versus equity, domestic versus international, and growth versus safety, to construct portfolios that aim to maximize expected returns while effectively managing risks.

Portfolio Management: Passive vs. Active

Portfolio management may be either passive or active.

Passive management is the set-it-and-forget-it long-term strategy. It may involve investing in one or more exchange-traded (ETF) index funds. This is commonly referred to as indexing or index investing. Those who build indexed portfolios may use modern portfolio theory (MPT) to help them optimize the mix.

Active management involves attempting to beat the performance of an index by actively buying and selling individual stocks and other assets. Closed-end funds are generally actively managed. Active managers may use any of a wide range of quantitative or qualitative models to aid in their evaluations of potential investments.

Active Portfolio Management

Investors who adopt an active management approach enlist the services of fund managers or brokers to engage in buying and selling stocks with the goal of outperforming a specific benchmark, such as the Standard & Poor’s 500 Index or the Russell 1000 Index.

An actively managed investment fund operates under the guidance of an individual portfolio manager, a team of co-managers, or a management team that actively makes investment decisions for the fund. The success of such funds hinges on a combination of thorough research, market analysis, and the expertise of the portfolio manager or team.

Portfolio managers practicing active investing closely monitor market trends, economic shifts, political developments, and relevant news that impact companies. This information is leveraged to strategically time the buying or selling of investments, aiming to capitalize on market anomalies. Advocates of active management argue that these processes enhance the potential for generating returns surpassing those achieved by simply replicating the holdings of a specific index.

However, attempting to outperform the market through active management introduces additional market risk. In contrast, indexing mitigates this particular risk since there is no possibility of human error in terms of stock selection. Index funds are also characterized by lower trading activity, resulting in reduced expense ratios and increased tax efficiency compared to actively managed funds.

Investors weigh the potential benefits and drawbacks of both active and passive approaches, considering factors such as investment objectives, risk tolerance, and the belief in the ability to consistently outperform the market.

Passive Portfolio Management

Passive portfolio management, also referred to as index fund management, aims to duplicate the return of a particular market index or benchmark. Managers buy the same stocks that are listed on the index, using the same weighting that they represent in the index.

A passive strategy portfolio can be structured as an exchange-traded fund (ETF), a mutual fund, or a unit investment trust. Index funds are branded as passively managed because each has a portfolio manager whose job is to replicate the index rather than select the assets purchased or sold.

The management fees assessed on passive portfolios or funds are typically far lower than active management strategies.

Portfolio Management: Discretionary vs. Non-Discretionary

Portfolio management encompasses the distinction between discretionary and non-discretionary management, which determines the extent of authority granted to a third party in managing your portfolio.

The discretionary and non-discretionary management styles specifically apply when you have an independent broker overseeing your portfolio. In a non-discretionary investment account, you instruct the broker to only execute trades that you have explicitly approved. The broker may provide advice on investment strategy and propose potential moves, but they are bound to follow your discretion and require your approval for any actions.

Conversely, some investors prefer to delegate all decision-making authority to their broker or financial manager. In such cases, the financial adviser has the power to buy or sell securities without seeking the explicit approval of the investor. However, even in discretionary management, the adviser maintains a fiduciary responsibility to act in the best interest of their client when managing the portfolio.

Investors have the flexibility to choose the approach that aligns with their preferences and level of involvement in the decision-making process. Whether opting for non-discretionary or discretionary management, it is crucial to establish a trusting relationship with the broker or financial adviser, ensuring they possess the necessary expertise and act in accordance with your best interests.

Key Elements of Portfolio Management

Asset Allocation

The key to effective portfolio management is the long-term mix of assets. Generally, that means stocks, bonds, and cash equivalents such as certificates of deposit. There are others, often referred to as alternative investments, such as real estate, commodities, derivatives, and cryptocurrency.

Asset allocation is based on the understanding that different types of assets do not move in concert, and some are more volatile than others. A mix of assets provides balance and protects against risk.

Investors with a more aggressive profile weight their portfolios toward more volatile investments such as growth stocks. Investors with a conservative profile weight their portfolios toward stabler investments such as bonds and blue-chip stocks.

Rebalancing captures recent gains and opens new opportunities while keeping the portfolio in line with its original risk/return profile.


The only certainty in investing is that it is impossible to consistently predict winners and losers. The prudent approach is to create a basket of investments that provides broad exposure within an asset class.

Diversification involves spreading the risk and reward of individual securities within an asset class, or between asset classes. Because it is difficult to know which subset of an asset class or sector is likely to outperform another, diversification seeks to capture the returns of all of the sectors over time while reducing volatility at any given time.

Real diversification is made across various classes of securities, sectors of the economy, and geographical regions.


Rebalancing is used to return a portfolio to its original target allocation at regular intervals, usually annually. This is done to reinstate the original asset mix when the movements of the markets force it out of kilter.

For example, a portfolio that starts out with a 70% equity and 30% fixed-income allocation could, after an extended market rally, shift to an 80/20 allocation. The investor has made a good profit, but the portfolio now has more risk than the investor can tolerate.

Rebalancing generally involves selling high-priced securities and putting that money to work in lower-priced and out-of-favor securities. The annual exercise of rebalancing allows the investor to capture gains and expand the opportunity for growth in high-potential sectors while keeping the portfolio aligned with the original risk/return profile.


An important aspect of portfolio management involves optimizing the portfolio’s tax efficiency over the long term. This entails considering how various retirement accounts are utilized, the duration of holding securities, and the selection of specific securities.

One example is the utilization of tax-exempt bonds. These bonds offer the benefit of tax-exempt dividends, meaning the income earned from these bonds is not subject to taxes. In contrast, the IRS applies different rules for short-term and long-term capital gains taxes. Individuals earning less than $41,675 in 2023 may have a capital gains rate of $0. However, for individuals with income above this limit, a short-term capital gains tax rate of 15% may apply.

Portfolio managers take these tax considerations into account when shaping the portfolio. They may strategically allocate investments across different retirement accounts, taking advantage of the tax benefits offered by each account type. They also assess the optimal holding periods for securities, as longer holding periods can potentially qualify for more favorable tax rates on capital gains.

By carefully managing the tax implications of the portfolio, investors aim to minimize their tax liabilities and maximize their after-tax returns. This involves staying informed about the evolving tax regulations and employing tax-efficient investment strategies within the framework of the law.

Common Portfolio Management Strategies

Every investor’s specific situation is unique. Therefore, while some investors may be risk-averse, others may be inclined to pursue the greatest returns (while also incurring the greatest risk). Very broadly speaking, there are several common portfolio management strategies an investor can consider:

  • Aggressive: An aggressive portfolio prioritizes maximizing the potential earnings of the portfolio. Often invested in riskier industries or unproven alternative assets, an investor may not care about losses. Instead, the investor is looking for the “home run” investment by striking it big with a single investment.
  • Conservative: On the other hand, a conservative portfolio relates to capital preservation. Extremely risk-adverse investors may adopt a portfolio management strategy that minimizes growth but also minimizes the risk of losses.
  • Moderate: A moderate portfolio management strategy would simply blend an aggressive and conservative approach. In an attempt to get the best of both worlds, a moderate portfolio still invests heavily in equities but also diversifies and may be more selective in what those equities are.
  • Income-Orientated: Often a consideration for older investors, some folks who do not have income may rely on their portfolio to generate income that can be used to live off of. Consider how a retiree no longer has a stable paycheck. However, that retiree may no longer be interested in generating wealth but instead of using their existing wealth to live. This strategy priorities fixed-income securities or equities that issue dividends.
  • Tax-Efficient: As discussed above, investors may be inclined to focus primarily on minimizing taxes, even at the expense of higher returns. This may be especially important for high-earners who are in the highest capital gains tax bracket. This may also be a priority for young investors who have a very long way until retirement. By getting started with a Roth IRA, these investors may be able to grow their portfolio over their entire life and face no federal taxes on withdrawal when they retire.

Challenges of Portfolio Management

Regardless of the chosen strategy, portfolio management faces several challenges that cannot be completely eliminated. Even with a well-designed portfolio management strategy, market fluctuations and volatility can be unpredictable, potentially leading to significant losses.

Diversification, while important for managing risk, can be challenging to achieve. It requires finding the right balance of asset classes and investments to align with risk and return objectives. Building a diversified portfolio can also be costly, as it may involve purchasing a wide range of securities.

To develop an effective portfolio management strategy, investors need a clear understanding of their risk tolerance, investment horizon, and return expectations. It is essential to establish both short-term and long-term goals, considering potential changes in life circumstances. Some strategies may limit investment liquidity or flexibility, so it’s important to be mindful of such constraints. Moreover, tax legislation changes implemented by the IRS can necessitate adjustments to the overall strategy.

If an investor chooses to engage a portfolio manager, management fees will be incurred. The portfolio manager must adhere to regulatory reporting requirements, and their opinions and concerns about the market may differ from those of the investor.

Navigating these challenges requires ongoing monitoring, evaluation, and potential adjustments to the portfolio management strategy. It is crucial to stay informed about market conditions, regulatory changes, and any evolving factors that may impact the portfolio’s performance.

What Are the Types of Portfolio Management?

Broadly speaking, there are only two types of portfolio management strategies: passive investing and active investing. Passive management is a set-it-and-forget-it long-term strategy. Often referred to as indexing or index investing, it aims to duplicate the return of a particular market index or benchmark and may involve investing in one or more exchange-traded (ETF) index funds. Active management involves attempting to beat the performance of an index by actively buying and selling individual stocks and other assets. Closed-end funds are generally actively managed.

What Is Asset Allocation?

Asset allocation involves spreading the investor’s money among different asset classes so that risks are reduced and opportunities are maximized. Stocks, bonds, and cash are the three most common asset classes, but others include real estate, commodities, currencies, and crypto. Within each of these are sub-classes that play into a portfolios allocation. For instance, how much weight should be given to domestic vs. foreign stocks or bonds? How much to growth stocks vs. value stocks? And so on.

What Is Diversification?

Diversification involves owning assets and asset classes that have been shown over time to move in opposite directions. When one asset class performs poorly, other asset classes usually prosper. This provides a cushion to your portfolio, offsetting losses. Moreover, financial mathematics shows that proper diversification can increase a portfolio’s overall expected return while reducing its riskiness.

What Is the Objective of Portfolio Management?

The objective of portfolio management is to create and maintain a personalized plan for investing over the long term in order to meet an individual’s key financial goals. This means selecting a mix of investments that matches the person’s responsibilities, objectives, and appetite for risk. Further, it means reevaluating the actual performance of the portfolio over time to make sure it is on track and to revise it as needed.

What Does an Investment Portfolio Manager Do?

An investment portfolio manager meets with a client one-on-one to get a detailed picture of the person’s current financial situation, long-term goals, and tolerance for risk. From there, the portfolio manager can draw up a proposal for how the client can meet their goals. If the client accepts the plan, the portfolio can be created by buying the selected assets. The client may start out by contributing a lump sum, or add to the portfolio’s balance periodically, or both. The portfolio manager takes responsibility for monitoring the assets and making changes to the portfolio as needed, with the approval of the client. Portfolio managers generally charge a fee for their service that is based on the client’s assets under management.


When it comes to growing your wealth, you have options to consider. You can take on the role of an investment portfolio manager yourself or opt to hire a professional to handle it for you. You can choose a passive management strategy by investing in index funds or take an active approach by frequently reallocating your investments.

Regardless of your chosen path, it’s crucial to focus on the fundamentals of portfolio management. First, select a combination of assets that helps mitigate overall risk. Diversify your holdings across different asset classes to optimize potential returns. Regularly rebalance your portfolio to maintain the desired asset mix and risk level. This ensures that your portfolio stays aligned with your investment objectives.
