Management Strategy Comparison: Active vs. Passive
In the realm of alternative investments, active management in the equity hedge fund sector is a popular strategy for generating alpha, or excess returns not driven by market risk. This approach, however, comes with its own set of challenges, as active managers strive to deliver consistent outperformance in a market landscape that presents numerous hurdles.
One of the main obstacles is the cost factor. Active funds typically charge significantly higher management and expense fees than passive funds, with an average annual cost of around 1.38% more than passive funds. Over time, these fees can erode net investor returns significantly [4].
Another challenge lies in the efficiency of the markets. Most active managers struggle to generate consistent alpha because markets are relatively efficient, making it hard to identify mispriced securities regularly. Studies show that a large majority of active funds underperform their benchmark indices over long periods, for example, 64% of US large-cap funds underperformed the S&P 500 over 24 years [4].
The growing dominance of passive investing can also create complex market dynamics. This environment, marked by increased volatility and price distortions, especially in large-cap stocks, can make active management riskier and more challenging, discouraging active managers from correcting mispricings, which in turn limits their ability to outperform [1][2].
Passive investing’s rising popularity can also create feedback loops that amplify price movements in certain stocks, increasing idiosyncratic risk and complicating active managers’ decisions. Active funds sometimes take short positions against heavily weighted index stocks, which further adds risk to their portfolios [1].
Given these challenges, the author of this strategy prefers an approach that balances active management with low-cost passive investments. The focus is on market-neutral/low to no beta strategies for pure alpha returns, using models like the Capital Asset Pricing Model (CAPM) and the Arbitrage Pricing Theory (APT).
Using CAPM, the author invests in passive, low-cost investments within each asset class for market risk exposure. For non-market factor exposures like Fama-French’s 4 factors and Carhart’s momentum factor, the author uses APT to invest in passive, low-cost ETFs.
The author also avoids equity hedge funds that are heavily exposed to market risk, i.e. have a significant beta coefficient. Instead, a smaller allocation is given to risks/exposures that can be provided by active managers, such as hedge funds, to help diversify the portfolio and add to the portfolio’s return in terms of alpha.
The author believes in paying low fees for market risk, other known risk factor exposures, and paying performance fees for exposure to Beta/systematic risk-neutral exposures such as idiosyncratic risk, new/not well-known factor risk(s), and alpha generation.
In 2019, hedge fund active managers with a 2&20 fee model needed to return an additional 55.44% on top of the passive investment's gain to just break even on a net return basis versus the passive investment. This underscores the need for a well-thought-out approach that balances active management with passive investments to achieve optimal returns.

Active management in finance, particularly in the equity hedge fund sector, faces a cost hurdle when compared to passive funds, as active funds often charge higher management and expense fees. Furthermore, the efficiency of the financial markets presents another challenge for active managers, as they strive to identify mispriced securities consistently.
