The Evolution of Hedge Funds in the Data Era

The efficient market hypothesis states that all asset prices perfectly reflect the available Information and Alpha, and that the price of any given asset is constantly being efficiently set by market forces.

This is code.

This is light code.

This is SQL code. 

Such that, all things considered equal and fair, it is essentially impossible to "beat the market."

While, in theory, this approach can be considered globally accurate, the reality of markets is that Alpha is often defined and achieved by the asymmetric nature of the information shared between buyers and sellers.

The fundamental theory of efficient markets rests upon the basic ideal that information, risk, and Alpha can be made equally accessible to buyers and sellers to create market conditions reflecting a "fair market value." Yet many of these conditions have been, or had been, essentially impossible without the invention of numerous data centric technologies like databases, data streams, live market pricing, and the internet that have developed over time to support efficient markets.

The harsh reality of efficient markets is that they are genuinely only "efficient" when participants can accurately assess ALL of the available information and provide pricing forces on the market to drive the supply and demand of any given asset.

All of this being said, in the modern era, the firms with the most significant outsized impact on the market are the Hedge Funds.

Named after the concept of "a hedge," or a strategy that aims to limit or offset the risk of adverse price movement in an asset or investment. The current Hedge Fund ecosystem comprises tens of thousands of global firms with trillions of dollars in held assets, all actively competing in different areas of the market. These firms employ strategies such as short selling, derivatives investing, and leverage to buy and sell other assets and achieve financial growth.

Yet the one element that defines these firms is their active, if not structurally dependent need for data. From the beginning of the first funds to the modern-day AI-driven, algorithmically traded ETFs, every fund depends on data to make decisions and compete in the market.

In this article, we will provide a quick dive into the evolution of hedge funds and their uses of data for various applications while outlining how the future of markets will depend more on data-based decision-making than ever before.

The History of Data in Hedge Funds

Hedge funds have long relied on traditional data sources for their investment strategies.

Traditional financial data, such as company filings, earnings reports, and economic indicators, have been the backbone of investment decision-making for over 100 years. Since the early 1960s, financial data companies like Compustat have supplied detailed financial information on publicly held companies via tabular data like income, balance sheets, and cash flow statements. However, the limitations of traditional data sources, such as their inability to provide real-time insights and the potential for biases and inaccuracies, led to the search for more innovative, bleeding-edge data sources.

From the 1960s to the late 1990s, the evolution of data sources like modern databases and the advent of computerized trading significantly transformed the financial industry. This period saw the rise of what can be considered modern-day hedge funds and the adoption/development of algorithmic trading, which relied heavily on data sources for their operations.

These hedge funds, which grew spectacularly in the 1980s and boomed in the 1990s, relied on various databases for their operations (TASS, SEC Filings, etc..). However, these databases often had limitations due to the limits  of the data available and the overall secretive nature of hedge funds, as they are not required by law to report their returns to any single database or even to regulators. As such, the firms with the most accurate datasets and the most developed decision-making criteria allowed them to succeed where their competitors failed.

And with the creation of the internet in the early 90s and the big boom in digital data sources, hedge funds began leveraging alternative data sources to add to the models and datasets they were using to pick stocks and place bets on the market. Data sources like credit card transactions, geolocation data, geospatial data, and internet search histories started playing a crucial role in informing investment decisions. These alternative data sources gave hedge funds a more granular view of consumer behavior and market trends, often in real-time.

This shift marked a significant departure from the traditional reliance on historical financial data, enabling hedge funds to anticipate market movements more accurately and react to changes swiftly. While simultaneously learning from and leveraging the fundamental style analysis that had proven successful in the prior years.

In essence, the history of hedge funds is a history that is closely tied with the use of data to make efficient market decisions and to drive better performance within the funds that are created. Now more than ever, data is being leveraged across firms to make the best possible bets and to create models of the market that define a systematic and rules-based approach to creating returns for the customers of these funds.

Modern Uses of Data in Hedge Funds

In the evolving landscape of hedge funds, data has emerged as a critical asset, driving decision-making and strategy formulation. The advent of advanced analytics and machine learning has revolutionized the way hedge funds operate, enabling them to leverage data in various aspects of their operations.

Here are some key areas where data plays a pivotal role in hedge funds:

Portfolio Management and Risk Analysis

Modern hedge funds possess vast data about their trades and investment decisions. This data, collected from various divisions, funds, and investment groups, is used to manage portfolios and analyze risk. Unique risk management approaches, often proprietary to the organization, are built around specific investment theses. However, the challenge lies in modeling, analyzing, reporting, and standardizing this data in an actionable way for the more advanced, data-driven firm. Tools have emerged to address this issue (like Sigma), providing an integrated platform for building highly customized portfolio management tools and reports. This allows for real-time access across businesses and data warehouses, creating a centralized repository of all financial information while empowering portfolio managers to use the most advanced and modern models the firms have provided. 

Compliance and Regulatory Reporting

Hedge funds face stringent regulatory pressures to comply with modern data governance and operational requirements. Internal and external compliance practices can change rapidly; managing compliance can be labor-intensive and risky without a centralized data repository and flexible analytics infrastructure. With recent changes in the reporting and performance requirements for funds of various sizes, a flexible approach to data analytics, modeling, and operational workflows is essential, enabling firms to build specific reporting tools for managing compliance and quickly being able to report upon regulatory requests. If these funds fail to manage risk and stay compliant the risks can be disastrous.

Market Analysis and Investment Discovery

Financial markets are complex and varied, and building proprietary models of the market is one of the most competitive and differentiating actions a fund can take. Lowering the barrier to entry for asset management companies to develop sophisticated market models without employing large teams of data scientists and analysts is crucial. By providing a visual interface for consolidating internal and external data sources that are all joined together into a single warehouse, it's possible to enable quick organization and consolidation of necessary data sources and build upon those to iterate on deployable, actionable models of the market.

Performance Management and Reporting

Performance management is a crucial aspect of a hedge fund's operational cadence. The old adage, "You can't manage what you don't measure," rings especially true for funds with multiple branches, portfolio managers, and strategies. Operations and investment teams want to implement performance tracking across their datasets or specific performance metrics (Portfolio mangager performance, category performance, risk tolerance, etc.).

Investment Forecasting and Modeling

Forecasting the future based on various assumptions is challenging in existing applications and tools available to asset managers. Providing a unique way of forecasting and modeling virtually any underlying dataset with tools like input tables and charting/analysis workbook capabilities allows funds to model a variety of assumptions or scenarios without building customizable code-driven models.

As the hedge fund industry continues to evolve in the data era, the importance of data will only continue to grow. Tools like Sigma have proven invaluable in this context, offering innovative solutions across these critical areas and facilitating more efficient and effective use of data in the dynamic world of hedge funds.

Summarizing the past and projecting the future

Global financial markets have always depended on high-quality data sources and "modern" data tools to make more efficient market decisions. From traditional paper filings and the emergence of the first quantitative analysis models, the evolutions of hedge funds in the data era is marked by an ever-growing demand to have live access to ultra-high-quality datasets, proprietary analysis, and market models, and decision-making frameworks that give funds the ability to accurately place bets on market conditions. Tools like Snowflake, dbt, Bloomberg, and Sigma are actively helping funds develop a competitive advantage to ride the changes in the market.

While in theory, there is no way to "beat the market," in practice, we've found that the firms leveraging data and with the most robust data practices in place, are the one that have the best shot of doing so.
