Unites de compte (UC) are investment vehicles within your assurance vie contract that allow you to invest in financial markets, real estate, and other asset classes beyond the capital-guaranteed fonds euros. Unlike the fonds euros, which guarantees your capital, unites de compte carry a risk of capital loss but offer significantly higher long-term return potential. In 2024, the best equity UCs delivered returns exceeding 20%, while fonds euros averaged 2.50%. Over 10 to 20 years, the performance gap between a well-constructed UC portfolio and a fonds euros-only approach can amount to tens of thousands of euros.

Understanding how to select the right UCs for your situation is therefore crucial. This guide provides a practical methodology adapted to all experience levels, from first-time investors to seasoned self-managers.

Understanding the Different Types of Unites de Compte

Equity Funds (OPCVM Actions)

Equity funds invest primarily in stocks of publicly listed companies. They are the primary growth engine of an assurance vie portfolio.

By geographic zone:

  • Global funds: MSCI World ETF, MSCI ACWI -- broadest diversification, over 1,500 companies across 23 developed countries
  • US-focused funds: S&P 500 ETF, Nasdaq-100 ETF -- access to the world's largest and most innovative economy
  • European funds: Euro Stoxx 50 ETF, MSCI Europe -- exposure to European blue chips
  • Emerging markets funds: MSCI Emerging Markets ETF -- higher risk/reward profile, exposure to China, India, Brazil

By style:

  • Growth funds: focused on companies with high revenue growth (technology, biotech)
  • Value funds: focused on undervalued companies with solid fundamentals (energy, finance, industrials)
  • Dividend funds: focused on companies paying regular and growing dividends

Expected returns: 7-10% annualized over 20 years for global diversified equity, with annual volatility of 15-20%.

Bond Funds (OPCVM Obligataires)

Bond funds invest in government and corporate debt securities. They serve as a stabilizer and income generator in a portfolio.

  • Government bond funds: sovereign debt from France (OAT), Germany (Bunds), or US Treasuries. Lower risk, lower returns.
  • Investment grade corporate bonds: debt from solid companies (rating BBB or above). Moderate risk, moderate returns.
  • High yield bonds: debt from lower-rated companies. Higher risk, higher returns (5-7% historically).
  • Dated bond funds (fonds dates): bond funds with a fixed maturity date, offering visibility on returns if held to maturity. Particularly attractive in the current rate environment.

Expected returns: 3-5% annualized for investment grade, 5-7% for high yield.

Real Estate Funds (SCPI, SCI, OPCI)

Real estate UCs provide exposure to property markets without direct ownership:

  • SCPIs (Societes Civiles de Placement Immobilier): invest in commercial and residential property, distributing rental income. Returns of 4-7% per year. Available on Linxea Spirit 2 (30+ SCPIs), Lucya Cardif, Placement-direct Vie.
  • SCIs (Societes Civiles Immobilieres): pooled real estate vehicles, often more liquid than SCPIs.
  • OPCIs: semi-liquid real estate funds combining property, listed securities, and cash.

ETFs (Tracker Funds)

ETFs (Exchange-Traded Funds) replicate an index passively at very low cost. They are the most cost-efficient way to invest in UCs:

  • Fees: 0.07% to 0.40% per year (vs 1.50-2.50% for actively managed OPCVM)
  • Transparency: exact composition known at all times
  • Performance: 85% of active managers fail to beat their benchmark index over 10 years
  • Availability: Linxea Spirit 2 offers 40+ ETFs; Lucya Cardif offers 50+ ETFs

Other Specialized UCs

  • Private equity funds: invest in unlisted companies. Higher risk, higher expected returns (10-15%). Available on Ramify and some Linxea contracts.
  • Structured products (fonds structures): capital protection combined with conditional upside. Complex instruments that require careful analysis.
  • Monetary funds: very low risk, currently yielding 3-3.5% thanks to the rate environment.

Building Your UC Portfolio: Step-by-Step Methodology

Step 1: Define Your Risk Profile

Your risk profile determines the split between fonds euros (safe) and UCs (growth):

ProfileFonds EurosUCsTypical Investor
Cautious70-80%20-30%Near retirement, short horizon
Balanced40-60%40-60%Mid-career, 10-15 year horizon
Dynamic20-30%70-80%Young investor, 15-25 year horizon
Aggressive0-15%85-100%Very long horizon, high risk tolerance

Step 2: Choose Your Core Allocation (60-80% of UCs)

The core should be broadly diversified and low-cost. The MSCI World ETF is the gold standard:

  • Amundi MSCI World ETF (CW8): 0.18% TER, 1,500+ companies across 23 countries, available on Linxea Spirit 2, Lucya Cardif
  • iShares Core MSCI World: 0.20% TER, physically replicated, available on multiple contracts

For more granular control, you can split the global allocation:

  • 60% US (S&P 500 ETF, 0.07% TER)
  • 25% Europe (MSCI Europe ETF, 0.12% TER)
  • 10% Emerging Markets (MSCI EM ETF, 0.18% TER)
  • 5% Japan/Pacific (MSCI Pacific ETF)

Step 3: Add Satellite Positions (20-40% of UCs)

Satellites complement the core with specific convictions or diversification:

  • SCPI (10-20%): Remake Live (7.79% in 2024), Iroko Zen (7.12%), Corum Origin (6.06%) -- available on Linxea Spirit 2
  • Bond funds (10-15%): for income and stability -- dated bond fund or investment grade ETF
  • Thematic funds (5-10%): technology, healthcare, clean energy -- for specific convictions
  • Small caps (5-10%): higher growth potential, higher volatility

Step 4: Set the Allocation and Automate

Once your allocation is defined:

  1. Execute the initial allocation on your contract
  2. Set up scheduled deposits with the same allocation percentages
  3. Activate annual automatic rebalancing (free on Linxea Spirit 2, Lucya Cardif)
  4. Review annually and adjust if your situation changes

Example portfolio: Camille, 33, product manager in Lyon

Camille has 25,000 euros to invest on Linxea Spirit 2, plus monthly deposits of 300 euros. Her horizon is 25+ years (retirement). She chooses a dynamic allocation:

  • 25% Fonds euros Spirica Nouvelle Generation (3.13% in 2024)
  • 45% Amundi MSCI World ETF (0.18% TER)
  • 10% iShares Core S&P 500 ETF (0.07% TER)
  • 10% SCPI Remake Live (in UC, 7.79% in 2024)
  • 10% Amundi MSCI Emerging Markets ETF (0.20% TER)

Total annual fees: approximately 0.75% (0.50% contract + 0.18% average ETF TER + 0.07% blended). Over 25 years with a hypothetical 6.5% net return, Camille's 25,000 euros initial + 300 euros/month could grow to approximately 310,000 euros.

Common Mistakes When Selecting Unites de Compte

Mistake 1: Chasing Last Year's Top Performer

The fund that gained 30% last year will not necessarily repeat. Academic studies show that performance persistence is weak among active funds: a top-quartile fund has only a 25-30% chance of staying in the top quartile the following year, barely better than random.

Mistake 2: Ignoring Fees

An OPCVM charging 2.5% per year must beat its index by 2.5 points just to match a low-cost ETF. Over 20 years, the fee difference between a 2% OPCVM and a 0.20% ETF on a 50,000 euro investment can exceed 45,000 euros.

Mistake 3: Concentrating on a Single Sector or Country

Investing everything in French equities (CAC 40) or technology stocks creates excessive concentration risk. The CAC 40 gained only 3.2% in 2024 while the S&P 500 surged 23%. Diversify across geographies, sectors, and asset classes.

Mistake 4: Having Too Many Funds Without a Strategy

Holding 15 different OPCVMs does not guarantee diversification if they all invest in the same large-cap global stocks. A simple portfolio of 3-5 well-chosen ETFs can provide better diversification than 15 overlapping active funds.

Mistake 5: Never Rebalancing

A portfolio left unattended drifts: equities that outperform take an ever-larger share, increasing risk without conscious decision. Rebalance at least annually, or activate the automatic rebalancing option on your contract.

Mistake 6: Panic Selling During Market Downturns

Selling UCs during a crash locks in losses that were until then only theoretical. Historically, markets have always recovered from their crises. The March 2020 Covid crash was followed by a full recovery within 5 months. The 2022 correction was followed by a 20%+ rally in 2023.

Selecting UCs Based on Your Contract

Not all contracts offer the same range of UCs. Here is what to expect on the main online contracts:

Unit-linked fund availability on major online assurance vie contracts
ContractTotal UCsETFs AvailableSCPIs AvailableStandout Features
Lucya Cardif2,300+50+25+Broadest selection on market
Linxea Spirit 2700+40+30+Best for SCPI investing (100% income pass-through)
Placement-direct Vie1,000+50+20+Good all-around selection
Boursorama Vie450+30+10+Easy-to-use interface
Linxea Avenir 2600+30+15+Low minimum (100 EUR)
Fortuneo Vie200+15+5+Simple, accessible

Key Takeaways

  • UCs are the growth engine of your assurance vie; the fonds euros alone rarely beats inflation over the long term
  • ETFs should form the core of your UC portfolio: low cost (0.07-0.40%), transparent, and they beat 85% of active managers over 10 years
  • A simple portfolio of 3-5 ETFs plus fonds euros can outperform complex multi-fund strategies
  • Diversify across geographies (global or US+Europe+Emerging), asset classes (equities, bonds, real estate), and investment styles
  • Total fees (contract + funds) should ideally stay below 1% per year; exceeding 2% will significantly erode long-term returns
  • Automate everything you can: scheduled deposits, allocation percentages, annual rebalancing
  • Review your allocation annually, but resist the urge to change your strategy based on short-term market movements
