Investment funds and mutual funds: essential definitions

What is an investment fund?

An investment fund is a collective investment vehicle that pools the capital of several investors in order to manage it according to a predefined strategy. This strategy is formalized in the fund's regulatory documentation, including the prospectus and the regulations.

The concept of investment funds is broad. It encompasses both funds invested in liquid financial markets and funds exposed to unlisted or illiquid assets, such as direct real estate or private equity.

An investment fund does not pursue a guaranteed return objective. It constitutes an organized framework for collective management, subject to operating and control rules, but exposed to risks related to the markets and underlying assets.

What is an investment fund?

The term investment fund refers more specifically to collective investment vehicles governed by specific prudential rules and intended for categories of investors defined by regulation.

In the European environment, investment funds most often take the form of UCITS or alternative investment funds. They are subject to strict requirements in terms of diversification, liquidity, transparency, and investor information.

The investment fund therefore operates within a standardized regulatory framework, without eliminating the financial or asset risks associated with the investment.

How does an investment fund work?

Capital raising and pooling

An investment fund raises capital from several investors. This capital is pooled within a single vehicle. Each investor holds units or shares representing a fraction of the fund.

Depending on the nature of the fund, subscriptions and redemptions may be frequent or, conversely, limited in time. Some funds provide for commitments that are called in progressively. These mechanisms may result in liquidity constraints.

Implementation of the management strategy

The management company implements the strategy defined in the regulatory documentation. It selects assets, makes arbitrage decisions, and adjusts the allocation in line with market developments and the fund's constraints.

This management is based on formalized processes, including investment committees, risk limits, and internal controls. It does not eliminate market, credit, or liquidity risks.

Governance and regulatory framework

The operation of a fund relies on several parties. The custodian is responsible for safekeeping the assets and monitoring certain transactions. Auditors certify the accounts. Supervisory authorities ensure compliance with regulations.

These measures are intended to enhance transparency and investor protection, but do not constitute a guarantee against losses or volatility.

Investment funds and mutual funds: what are the differences?

Scope and use of terms

An investment fund is a generic term. It refers to all collective investment vehicles, whether open-ended or closed-ended, liquid or illiquid, accessible to the general public or reserved for professional investors.

The investment fund refers more specifically to regulated structures designed to be distributed to identified categories of investors, with specific requirements in terms of information and operation.

Legal structure

Investment funds are generally structured as UCITS or alternative investment funds. Investment funds, in the broad sense, also include private or specialized structures, sometimes reserved for a limited number of investors.

Assets, risk, and liquidity

Investment funds may be exposed to a wide variety of assets, including illiquid assets. Investment funds are often subject to additional diversification or liquidity constraints.

The level of risk depends primarily on the strategy and assets held, not on the terminology used.

The main types of funds in 2026

Equity and bond funds

These funds invest primarily in listed securities. Their value may fluctuate significantly depending on financial markets, interest rates, and economic conditions.

Diversified funds

Diversified funds combine several asset classes within a single portfolio. This approach aims to spread exposure, without eliminating the risk of capital loss.

Real estate funds

Real estate funds offer indirect exposure to real estate, most often commercial real estate. They present specific risks related to asset valuation, liquidity, and real estate market conditions.

Private equity fund

Private equity funds invest in unlisted companies. They have a long-term focus and limited liquidity. The risk of capital loss is high.

Impact and sustainable funds

These funds incorporate environmental, social, or governance criteria into their investment process. Approaches vary depending on the fund and do not guarantee results or measurable impact.

Key elements analyzed

Investors generally examine the fund's strategy, the management company's organization, liquidity constraints, fee structure, governance, and the quality of available information.

This analysis does not replace the assessment carried out by a qualified professional.

Horizon liquidity

The investment horizon must be consistent with the nature of the underlying assets. Some funds involve a prolonged lock-up of capital, with no possibility of early redemption.

Diversification

Diversification across different types of assets or strategies can help limit certain risk concentrations. It does not eliminate the possibility of losses.

What is the difference between an investment fund and a mutual fund?

An investment fund is a generic term that refers to any collective investment vehicle, regardless of its legal structure, level of liquidity, or target audience.

The investment fund refers more specifically to regulated vehicles, such as UCITS or alternative investment funds, designed to be distributed to identified categories of investors.

Why are these two terms often confused?

In everyday language, the terms investment fund and mutual fund are often used interchangeably. This confusion stems from the fact that many mutual funds are also, legally and economically, investment funds in the broad sense.

Is an investment fund a financial product?

An investment fund is not a product in the commercial sense of the term, but rather a collective investment vehicle. It is a legal and financial structure that allows for the holding of a portfolio of assets managed according to rules defined in its regulatory documentation.

How is a fund regulated?

A fund is governed by a set of rules covering its governance, asset preservation, investor information, and internal controls.

Several parties are involved, including the management company, the custodian, the auditors, and the supervisory authorities.

Do all funds operate in the same manner?

No. How a fund operates depends on its strategy, the nature of the assets it holds, its level of liquidity, and its regulatory framework. A fund that invests in listed markets does not operate in the same way as a fund that invests in unlisted assets.

Why do some funds impose a long investment horizon?

Some funds invest in assets that cannot be sold quickly, such as private equity or certain real estate assets.

The investment horizon is therefore linked to the time needed to invest, manage, and dispose of these assets under conditions compatible with the fund's strategy.

Where can I find detailed information about a fund?

Detailed information can be found in the fund's regulatory documentation, including the prospectus, key information document, and periodic reports. These documents describe how the fund operates, its strategy, risks, and practical arrangements.
