Alpha is the excess return achieved by a fund manager after accounting for beta-driven return. Beta refers to the market's overall return, while alpha represents the manager's skill in generating returns beyond what is explained by market movements. Choosing an appropriate benchmark is crucial for accurately assessing alpha.
The challenge in measuring alpha lies in correctly identifying all beta-driven factors in advance. Unrecognized beta factors may be mistaken for manager skill. Additionally, alpha is not static, and some strategies once considered alpha may later be recognized as beta. Therefore, selecting the right benchmark is crucial to avoid underestimating or overestimating a manager's skill in generating alpha-driven returns.
To generate alpha, fund managers need to deviate from the benchmark and relax investment constraints. Loosening constraints may involve:
Short Selling: Allowing short selling enables managers to profit from declining asset prices, adding a potential source of alpha.
Portfolio Concentration: Concentrating investments in a smaller number of assets allows managers to focus on their highest-conviction ideas. This concentration amplifies the impact of successful stock picks on overall portfolio performance.
Expanding Investment Universe: Managers can explore a broader range of markets, securities, and investment strategies. This flexibility provides more opportunities to uncover mispriced assets.
By breaking away from benchmark restrictions, fund managers can pursue unique strategies and exploit market inefficiencies, potentially generating excess returns. However, this increased freedom also comes with higher risks, as more unconstrained strategies can lead to greater volatility and the possibility of negative alpha.
Long/short investments play a crucial role in generating alpha for a portfolio manager. Here's a breakdown of how they work:
Market Neutral Strategy: Long/short investments allow a portfolio manager to create a market-neutral strategy by holding both long (buy) and short (sell) positions simultaneously. This strategy aims to eliminate or significantly reduce exposure to overall market movements (beta). If the manager achieves a fully hedged or market-neutral position, any positive return is considered alpha.
Beta Reduction: By combining long and short positions, the portfolio manager can adjust the net exposure to the market. For instance, in a 130/30 strategy (long 130%, short 30%), the resulting beta is 1, indicating a neutral market exposure. However, if the manager shortens the portfolio enough, beta can be reduced to zero, meaning the portfolio's return is driven entirely by alpha.
Stock Selection Skill: The return generated from a market-neutral strategy is attributed to the manager's stock-picking or security selection skill. If the manager achieves positive returns in a market where the overall performance is flat or declining, it demonstrates the ability to pick winning investments (alpha).
Hedging with Futures: Shorting the market through the sale of futures contracts on the index is a common method to hedge the long positions in individual stocks. This helps in achieving a market-neutral stance and isolating the stock selection skill from the overall market movements.
In summary, Long/Short investments provide a powerful tool for portfolio managers to enhance their alpha by focusing on stock selection rather than market direction. Achieving a market-neutral position through shorting allows managers to showcase their skill in choosing securities that outperform the broader market.
Portfolio concentration is another strategy that portfolio managers can use to generate alpha. Here's an explanation of how it works:
Concentrated Portfolios: Instead of holding a large number of securities, a concentrated portfolio involves making significant investments in a select few securities. This strategy allows the portfolio manager to take substantial positions in what they believe are the most promising opportunities.
Divergence from Benchmark: Concentrated portfolios intentionally deviate from the traditional approach of diversification, which aims to minimize tracking error relative to a benchmark. In contrast, a concentrated strategy assumes greater tracking error, meaning that the portfolio's performance may deviate significantly from the benchmark.
Active Return: The goal of a concentrated portfolio is to produce a larger active return. Active return represents the excess return generated by the portfolio manager's skill in selecting securities compared to the benchmark. In this case, any return above or below the benchmark is considered alpha.
Number of Securities: The number of securities held in a concentrated portfolio is relatively small compared to more diversified portfolios. It could range from a handful to a few dozen, depending on the manager's strategy and convictions about specific investments.
Investment Universe: Concentrated portfolios may include securities that are not part of the benchmark index, allowing the manager to explore opportunities beyond the benchmark's constraints. This flexibility enables the portfolio manager to seek alpha in areas where they believe the market is mispricing securities.
Alpha Driver: Concentration is considered an alpha driver because the excess return it aims to achieve is attributed to the manager's active decisions rather than broad market movements.
In summary, a concentrated portfolio focuses on a limited number of securities, allowing the manager to take larger positions and deviate from the benchmark. The potential for alpha comes from the manager's skill in selecting specific investments, and this strategy intentionally introduces tracking error in pursuit of higher active returns.
Absolute return investments represent a strategy where the primary objective is to achieve positive returns consistently, irrespective of broader market conditions. Here's an overview of how absolute return strategies work:
Objective: The main goal of an absolute return manager is to generate positive returns over a specified time period, regardless of whether the broader market is rising or falling. The focus is on achieving an absolute, positive return rather than outperforming a benchmark.
Unconstrained Style: Absolute return managers are not bound by traditional investment styles or benchmarks. They have the flexibility to employ a wide range of strategies, including long and short positions, derivatives, and alternative investments. This unconstrained approach allows them to adapt to changing market conditions and capitalize on various opportunities.
Diverse Investment Universe: Absolute return managers have the freedom to invest in a broad array of financial instruments, asset classes, and markets. They can explore opportunities in equities, fixed income, currencies, commodities, and alternative investments based on their assessment of risk and return potential.
Risk Management: While seeking positive returns, absolute return managers also prioritize risk management. They aim to control downside risk and preserve capital, emphasizing the importance of managing volatility and drawdowns.
Market-Neutral or Directional: Absolute return strategies can be market-neutral, meaning they attempt to hedge out market risk by balancing long and short positions. Alternatively, they may take directional bets on market movements, depending on the manager's assessment of market conditions.
Adaptability: The adaptability of absolute return strategies allows managers to respond to changing economic conditions, market trends, and geopolitical events. This flexibility is a key feature, enabling them to navigate diverse market environments.
Alpha in absolute return strategies is derived from the manager's ability to make skillful investment decisions that result in positive returns, regardless of market direction. Successful alpha generation requires astute risk assessment and the identification of mispriced opportunities.

In summary, absolute return investments focus on delivering positive returns in various market conditions, employing an unconstrained and adaptable approach. This strategy aims to generate alpha by making informed investment decisions across a diverse range of assets. ∞ALPHA
