The Complete Guide to Mutual Funds: Types, Operation and Advantages

Published on April 14th, 2025

Against a backdrop of increasingly sophisticated financial markets, investment funds have become an essential vehicle for investors seeking diversification, risk-adjusted performance and professional management. Rather than gaining direct exposure to financial assets, these collective instruments give investors access to delegated management based on rigorous strategic allocation.

This guide provides an in-depth analysis of fund types, how they work and the levers they offer to structure a portfolio that is resilient, efficient and in line with your investment objectives.

Definition of an investment fund

A mutual fund is a collective investment vehicle that pools the capital of several investors to acquire a selection of diversified assets: equities, bonds, money market instruments, real estate assets, or even unlisted investments. These funds are managed by financial market professionals, whose mission is to optimize performance by taking into account the risk/return trade-off.

The strength of these instruments lies in their ability to spread risk through sectoral, geographic and typological diversification. As a result, even an investor with modest capital can gain access to professional, structured financial exposure that can potentially outperform isolated individual investments.

Major mutual fund families

Mutual Funds (FCP)

FCPs combine investments in a wide variety of assets and are designed to offer instant diversification. They are governed by strict regulatory rules, and are a tool of choice for investors wishing to benefit from rigorous management while accessing a multi-asset allocation.

Specialized Investment Funds (SIF)

SIFs provide targeted exposure to forward-looking themes such as sustainable infrastructure, healthcare, artificial intelligence and green mobility. Their sector-based approach makes for a dynamic portfolio with a strong thematic focus.

Private equity funds

These funds invest in unlisted companies, often with high growth potential. They play an active role in the transformation of the companies they finance, while offering investors the prospect of higher returns, in return for a long holding period and reduced liquidity. Eurazeo Wealth Solutions offers a range of private equity funds accessible from €10,000.

Index funds (ETFs)

ETFs replicate the performance of an index (such as the CAC 40 or MSCI World), providing low-cost exposure to a broad universe of assets. They are an efficient solution for diversifying portfolios while optimizing management costs.

Why invest via an investment fund?

Access to professional management

Entrusting your capital to an experienced management team allows you to benefit from a dynamic allocation adapted to the economic environment.

Immediate diversification

The funds enable immediate allocation to different assets, thus limiting idiosyncratic risks.

Access to strategic opportunities

Some funds allow you to invest in asset classes that are inaccessible directly, such as unlisted assets, emerging markets or high-growth sectors.

Tax optimization

Depending on the investment vehicle chosen (PEA, life insurance, FCPI, FIP, etc.), certain funds offer significant tax advantages, enabling you to improve the net performance of your investments.

Choosing the right fund: Key criteria

Matching your investor profile

Each fund carries a different level of risk. It's crucial to ensure that the fund you choose matches your risk tolerance, investment horizon and asset objectives.

Performance history and transparency

Analysis of past performance (within the limits of its relevance) enables you to assess the consistency of the fund's strategy over different market cycles. Clear reporting and fee transparency are also essential criteria.

Regular monitoring

A successful fund must be rigorously managed, with periodic strategic adjustments to take account of market trends and opportunities.
