What Is Active Management?

Active management is an investment strategy where a professional fund manager or team makes specific investment decisions to outperform a designated market index or benchmark. This approach falls under the broader category of portfolio theory, focusing on generating returns through strategic asset allocation, security selection, and/or market timing. Unlike passive strategies, active management involves continuous research, analysis, and adjustments to a portfolio in an attempt to capitalize on perceived market inefficiencies. The primary goal of active management is to achieve alpha, which is the excess return above what would be expected from the market or a specific benchmark.

History and Origin

The concept of active management has existed as long as organized investing. Historically, most investment approaches were inherently active, as investors or their agents manually selected assets based on available information and market sentiment. The professionalization of portfolio management solidified this approach. However, the theoretical underpinnings of why active management might be challenging gained significant attention with the development of the Efficient Market Hypothesis (EMH). Pioneering work by economist Eugene Fama in the 1960s, notably his 1965 paper "A Random Walk in Stock Market Prices" and his influential 1970 review, posited that asset prices already reflect all available information, making it difficult for investors to consistently "beat the market"¹¹, ¹². Fama's work, for which he later shared the Nobel Prize in Economic Sciences in 2013, became a cornerstone in financial economics and spurred extensive research into the capabilities of active managers and the efficacy of the EMH¹⁰.

Key Takeaways

• Active management seeks to outperform a specific market benchmark through strategic investment decisions.
• It involves constant research, analysis, and adjustments to a portfolio, relying on security selection and market timing.
• The primary objective is to generate "alpha," which is a return above the benchmark.
• While active management offers the potential for higher returns, it typically comes with higher fees and does not guarantee outperformance.
• Performance of actively managed funds is frequently measured against passive benchmarks, with S&P Global's SPIVA Scorecard being a prominent example.

Formula and Calculation

While there isn't a single "formula" for active management itself, its success is often measured by the generation of alpha. Alpha quantifies the excess return of an investment relative to the return of a benchmark index, considering the investment's beta (market risk).

The formula for calculating alpha (Jensen's Alpha) is:

Where:

• (R_i) = Realized return of the investment (e.g., a specific actively managed fund)
• (R_f) = Risk-free rate of return (e.g., the return on a U.S. Treasury bill)
• (\beta_i) = Beta of the investment, which measures its sensitivity to market movements
• (R_m) = Realized return of the market benchmark (e.g., S&P 500)
• ((R_m - R_f)) = Market risk premium

A positive alpha indicates that the active manager has generated returns exceeding what would be expected given the portfolio's risk management and market exposure, suggesting skill. Conversely, a negative alpha indicates underperformance relative to the benchmark.

Interpreting Active Management

Interpreting active management primarily involves evaluating whether a fund manager has successfully achieved their goal of outperforming a benchmark after accounting for fees and risks. A key aspect of this interpretation is understanding the sources of any outperformance. It could stem from superior security selection, accurate market timing, or effective asset allocation decisions. Investors typically look for consistent positive alpha over extended periods, rather than short-term fluctuations, to ascertain true skill versus random luck. Given that active management carries higher fees than passive alternatives, the added value (alpha) must justify these costs.

Hypothetical Example

Imagine an investment firm manages the "Global Equity Growth Fund," an actively managed fund, with a primary objective to outperform the MSCI World Index.

• Fund's Starting Value: $10 million
• Benchmark (MSCI World Index) Return in one year: 10%
• Fund's Return in one year: 12%
• Management Fees: 1.0%
• Risk-free rate: 3%
• Fund's Beta: 1.1

To calculate the fund's alpha:

1. Expected Return: (R_f + \beta_i (R_m - R_f) = 3% + 1.1 \times (10% - 3%) = 3% + 1.1 \times 7% = 3% + 7.7% = 10.7%)
2. Alpha: (R_i - \text{Expected Return} = 12% - 10.7% = 1.3%)

In this hypothetical scenario, the Global Equity Growth Fund generated a positive alpha of 1.3% before considering management fees. After accounting for the 1.0% management fee, the net alpha would be 0.3%. This suggests the fund manager added value beyond the market's return for the level of risk taken. This is a crucial element in evaluating an investment strategy.

Practical Applications

Active management is widely used across various investment vehicles and strategies. It is the foundational approach for many mutual funds and hedge funds, where managers actively research and trade securities. Institutional investors, such as pension funds and endowments, also employ active management to achieve specific return objectives or manage liabilities⁸, ⁹. For instance, a pension fund might use active management for its fixed-income portfolio to capitalize on interest rate movements or credit opportunities.

Recently, there has been a significant rise in actively managed Exchange-Traded Funds (ETF), which combine the trading flexibility of ETFs with the strategic decision-making of active management. The U.S. Securities and Exchange Commission (SEC) has provided guidance and sought comments on the operations and disclosures related to these types of funds, acknowledging their evolving role in the financial landscape⁷. Active management is also applied in specific market segments like small-cap equities or emerging markets, where perceived inefficiencies might offer greater opportunities for skilled managers to generate outperformance⁶.

Limitations and Criticisms

Despite its appeal, active management faces significant limitations and criticisms. The most common critique centers on the difficulty of consistently outperforming the market over long periods, especially after accounting for fees. Data from S&P Global's SPIVA (S&P Indices Versus Active) Scorecard consistently shows that a majority of actively managed funds underperform their respective benchmarks across various asset classes and time horizons³, ⁴, ⁵. For example, a recent SPIVA report highlighted that over a 15-year period ending December 2024, no categories saw a majority of active managers outperform their benchmarks².

High management fees and trading costs associated with active management can erode any potential alpha, making it challenging for investors to achieve superior net returns. Furthermore, the skill of an investment strategy team in generating alpha may not persist over time, leading to inconsistent performance¹. Critics, often proponents of the Efficient Market Hypothesis, argue that because all public information is rapidly priced into securities, consistently finding undervalued assets or timing the financial market is largely a matter of luck rather than skill.

Active Management vs. Passive Management

The core distinction between active management and passive management lies in their investment objectives and methodologies.

While active management aims to beat the market by making calculated bets, passive management seeks to mirror market performance by investing in a diversified portfolio that tracks a broad market index. The debate between these two approaches often revolves around the empirical evidence regarding long-term outperformance and the impact of fees on net returns.

FAQs

What is the main goal of active management?

The main goal of active management is to outperform a specific market benchmark, aiming to generate returns (alpha) that exceed what a passive index-tracking strategy would provide.

Why do some investors choose active management despite higher fees?

Some investors choose active management because they believe a skilled fund manager can identify mispriced securities or make timely market calls that lead to superior returns, especially in less efficient or niche markets. They might also seek specialized risk management or specific investment themes not easily captured by passive indices.

How is active management different from simply picking stocks?

While active management involves security selection, it is a more comprehensive investment strategy that also includes broader asset allocation decisions, market timing, and sophisticated risk analysis within a structured portfolio management framework. It typically involves professional management of diversified portfolios rather than individual stock picking.

Does active management guarantee higher returns?

No, active management does not guarantee higher returns. While it aims for outperformance, many studies show that a majority of actively managed funds fail to consistently beat their benchmarks after fees over long periods.

What is the role of diversification in an actively managed portfolio?

Diversification remains crucial in an actively managed portfolio, even though managers may concentrate investments to generate alpha. It helps to mitigate unsystematic risk inherent in specific security selections, ensuring that no single investment drastically impacts overall portfolio performance if an active bet goes wrong.
