While AI technology has only just been thrust into the mainstream, fund managers have been utilizing the benefits of machine learning and advanced computing for many years. The vast improvements in this technology have created a remarkable surge in the popularity of quantitative investing, an investment approach that relies on mathematical models and data-driven strategies.

This growth has spawned an entire sub-sector of quantitative managed funds, which utilize quant strategies either exclusively, or very heavily.

The research indicates that one in five hedge funds now apply quant investment processes, and about 86% of hedge fund managers expect institutional investors to boost their investments in quant strategies within the next five years.

The article provides an overview of the main quantitative fund strategies, offers a list of the largest quantitative hedge funds, and explains the advantages and disadvantages of quantitative analysis. 

What is a quant?

Quant is short for a quantitative analyst, a professional who specializes in developing and implementing mathematical models and statistical techniques to analyze and solve complex financial problems for investment management.

A quant will spend far more time looking at code and raw data than delving through company statements, basing their day-to-day investment decisions on algorithmic patterns and predictions, rather than focusing purely on investment fundamentals.

By analyzing large sets of financial data, quant analysts can identify patterns, trends, and anomalies and generate insights and predictions. This information is useful for data-driven decision-making.

More specifically, this is valuable for:

  • Algorithmic trading
  • Portfolio management
  • Derivatives pricing
  • Risk assessment    
  • Developing trading strategies

Quants are typically employed by hedge funds, asset management firms, investment bankers, and other financial institutions for conducting quantitative analysis. These days, almost every financial institution will utilize quants in one form or another, even if quantitative investing isn’t their core investment philosophy.

Pros and cons of quantitative analysis

Learn the advantages and disadvantages of quantitative analysis.


  • Objectivity

It reduces the influence of biases, emotions, and human judgment and relies on data and mathematical models, providing an objective approach to decision-making.

  • Risk management

It allows for the development of risk models and strategies that can help mitigate potential losses and improve risk-adjusted returns.

  • Systematic approach

It provides a systematic and disciplined framework for decision-making, helping maintain consistency in trading strategies and reducing the impact of emotional and impulsive decisions.

  • Cost-effectiveness

Quant funds are generally more cost-effective than actively managed funds due to their passive and consistent strategy, which allows them to charge lower fees compared to other investment options.


  • Data quality

Quantitative analysis relies on historical data for predicting future events. However, it’s impossible to predict the future with complete accuracy consistently.

  • Complexity

Models used by quants can be incredibly complex and often lack transparency, even for those who create them. This can make it difficult to assess where a model is underperforming.

  • Market volatility and uncertainty

Quantitative models are based on historical data and assumptions, which don’t take into account sudden shifts in financial markets.

  • Competitiveness

The increased popularity of quantitative analysis has led to more participants using similar models and algorithms, which makes quant strategies less effective.

What is a quant fund?

A quant fund or a quantitative fund is an investment fund that applies mathematical and statistical analyses and software algorithms to make investment decisions. 

Furthermore, a quant fund is considered a combination of passive index funds and actively managed funds as it has shared features of both. In active funds, the fund manager is responsible for determining the asset selection and the timing of investment entry and exit through active trading. Passive funds are based on a set strategy and a set universe, with no discretion on the assets being bought and sold.

In contrast, quant funds have a set strategy and a set universe, but active trading is undertaken by the financial model and software. This strategy and investment universe can also be changed by the quant as they refine and improve their model.

The mechanism of quantitative funds

Typically, there are four main steps in the quantitative investment process:

  • Investment universe selection

The first step in the quantitative investment process is to decide which assets the investment strategy is going to target. Some examples could be Japanese equities, US small cap stocks, agricultural commodities, real estate investment trusts or any other market segment.

  • Data collection and processing

The next step is to select and gather the datasets that the model will be based off. It’s important that the source of this data is vetted, consistently available and as clean as possible, though some manual processing to remove outliers and irrelevant information is likely to be needed.

  • Model creation and backtesting

Once the data is ready to go, the quant will create statistical models which aim to predict the performance of the assets within the universe. Back testing is a vital part of the process, providing the ability to see how a model would have performed through various market cycles.

  • Portfolio implementation

With the model back tested and ready to be implemented, the quant can ‘go live’ and begin to review the performance and volatility of the fund in real market conditions.

A quantitative hedge funds list

Here’s a list of  5 of the top quant funds worldwide:

  • Renaissance Technologies

The company is one of the most successful quant hedge funds today. According to Zuckerman’s book, The Man Who Solved the Market, the Renaissance’s flagship Medallion fund has returned 66% annually, before fees, since 1998.

  • D.E. Shaw

 D.E. Shaw, founded in 1988, has been successful in achieving consistent returns and has grown to become one of the largest quant funds in the world. The firm employs a diverse team of mathematicians, scientists, engineers, and researchers.

  • Quantitative Management Associates (QMA)

 The QMA quant hedge fund is known for its expertise in factor investing, which involves targeting specific factors such as value, momentum, and quality to enhance portfolio performance. They apply quantitative techniques to identify and capitalize on these factors in a systematic manner.

  • Two Sigma

This quantitative hedge fund is known for its data-driven decision-making process, leveraging both traditional and alternative data sources to gain insights into market trends and make informed investment decisions.

  • Man AHL

 AHL is a prominent quantitative investment firm that specializes in systematic strategies. The fund benefits from the resources and global network of a larger financial organization—Man Group, while maintaining its quantitative expertise and autonomy.

Quantitative hedge fund strategies

The following are the most common quant strategies:

  • Value

This strategy seeks to invest in assets trading at a discount to their intrinsic value based on factors such as price-to-earnings (P/E) ratio, book value, and dividend yield

  • Event-driven arbitrage

This strategy aims to profit from corporate events such as M&A or spin-offs. Quantitative models are used to assess the potential impact of these events on stock prices and identify mispricings

  • Statistical arbitrage

It involves exploiting short-term pricing anomalies and mispricings in related securities. It uses quantitative models and statistical analysis to identify relationships and historical patterns between different assets

  • Risk parity

This strategy involves allocating portfolio weights based on risk rather than traditional asset allocation methods. It may not beat the returns generated by equity funds, but it provides a better risk-adjusted return

  • Factor-investing

This strategy involves selecting securities based on those which exhibit the characteristics of the factors that are predicted to provide the best risk-adjusted performance. Examples of these factors include momentum, value and growth

  • Systematic global macro strategies

These quantitative investment strategies aim to profit from macroeconomic events and trends across multiple asset classes, including equities, bonds, currencies, and commodities.

How to invest in quant funds?

Quant investing typically involves the following steps:

  • Research

Begin by researching different quant funds and understanding their investment strategies, historical performance, and risk profile. Evaluate factors such as the fund’s track record, investment team expertise, investment philosophy and strategy, risk management practices, and fees.

  • Identify investment goals

Choose funds that align with financial goals and risk appetite, as quant funds can vary in their investment styles.

  • Consult with a financial advisor

Consider consulting with an investment professional who has experience working with hedge fund investors and can help assess investment needs and recommend suitable quant funds.

  • Fund selection

Choose specific quant funds in which to invest based on research and recommendations. Consider diversifying the portfolio by allocating investments across multiple funds to spread risk.

  •  Track performance

Monitor the quant funds’ performance regularly. Review their performance reports, updates, and any changes in investment strategy or portfolio holdings.

Key takeaways

Here are the most essential points to consider:

  • A quant fund is an investment fund that utilizes mathematical models, statistical analysis, and computer-based algorithms and removes or limits human intervention to predict investment opportunities and make investment decisions 
  • The quantitative investment process includes the selection of an investment universe, data collection and processing, model creation and back testings and finally, implementation
  • Some of the largest quant hedge funds include Renaissance Technologies, D.E Shaw, Quantitative Management Associates (QMA), Two Sigma, and Man AHL
  • The most common quant fund strategies are value, event-driven arbitrage, statistical arbitrage, risk parity, factor-investing, systematic global macro, and multi-asset strategies.

Investing in quant funds requires a deep understanding of strategies, potential benefits, risks, peculiarities of asset allocation, and fund selection. Consider consulting a financial advisor for help identifying the best investment strategy.
