Why Active Funds Struggle to Generate Alpha Consistently

Why in the News ?

The 2025 SPIVA report indicates that nearly three-fourths of large-cap active funds underperformed their blended LargeMidCap benchmark over a 10-year period. This highlights the difficulty portfolio managers face in generating consistent alpha despite expertise and information.

Understanding Alpha: Skill versus Luck

●     Alpha refers to the excess return generated by a portfolio compared with an appropriate benchmark.

●     In simple terms, Alpha = Portfolio Return − Benchmark Return.

●     Alpha depends on two broad factors: portfolio-manager skill and luck.

●     Skill is influenced by:

○      Knowledge — acquired through education, professional qualifications and investment experience.

○      Information — corporate developments, economic data and other publicly available information used for investment decisions.

●     Differences in portfolio-manager skill have narrowed because:

○      Most professional managers possess broadly comparable qualifications and financial knowledge.

○      Market participants have access to largely the same publicly available information.

●     Therefore, differences in fund performance cannot always be explained by differences in managerial skill.

●     Luck can consequently play an important role in determining whether a skilled manager generates positive or negative alpha.

●     Even a highly capable portfolio manager can experience bad luck, causing temporary or prolonged underperformance.

Market Structure and Implications for Investors

●     The article describes financial markets as “efficiently inefficient”:

○      Markets can contain mispriced securities, creating opportunities for active managers.

○      However, such mispricing often disappears quickly because many investors compete for the same opportunities.

●     Cheap computing power, sophisticated analytical tools and widespread access to information have intensified competition among fund managers.

●     Consequently, identifying mispriced stocks significantly ahead of competitors has become increasingly difficult.

●     This does not mean that active funds cannot generate alpha or that investors should avoid them altogether.

●     However, consistently outperforming benchmarks requires overcoming both market competition and the element of luck.

●     For investors, the timing of underperformance is particularly important when investments are linked to specific financial goals.

●     Negative alpha during the period preceding a major life goal can create a wealth shortfall, potentially preventing the investor from achieving the required terminal wealth.

●     Hence, investment decisions should consider risk, time horizon, diversification and goal requirements, rather than relying solely on the possibility of excess returns.

 About Alpha and Active Fund Management :

●     Active fund management involves selecting securities with the objective of outperforming a benchmark.

●     Passive investing, in contrast, seeks to replicate the performance of a market index, generally at lower costs.

●     Alpha measures excess risk-adjusted or benchmark-relative performance, while beta broadly measures sensitivity to market movements.

●     Benchmark selection is crucial because alpha is meaningful only when portfolio performance is compared with an appropriate benchmark.

●     SPIVA (S&P Indices Versus Active) regularly compares actively managed funds with relevant market indices.

●     Persistent outperformance is difficult because of competition, information efficiency, transaction costs, management fees and market volatility.

●     For long-term investors, the focus should therefore extend beyond chasing alpha to asset allocation, risk management and alignment with financial goals.
