Since the Covid period, the number of individual investors in France has increased significantly. Reports from the AMF document a specific phenomenon: a significant portion of these new entrants engages in very sporadic activity, with a tendency to buy during market rises and to exit during stressful phases. Their average performance is thus degraded compared to a passive strategy on index ETFs held over the long term.
Understanding the stock market before investing money remains the condition to avoid joining this statistic.

Behavioral biases of new investors: the real barrier to performance
Most guides for starting in the stock market focus on choosing the investment wrapper or broker. The main problem lies elsewhere. Data from the AMF (Savings Observatory, reports 2023 and 2024) show that the buying-selling behavior of beginners destroys part of their returns. Buying when markets rise sharply, selling when they fall: this reflex, documented under the name of market timing, produces results inferior to those of regular and automated investing.
This observation has concrete consequences. Since 2024, several French and European neo-brokers have integrated programmed investing (automated monthly purchases of ETFs) by default when opening an account. Regulators present this option as a means to limit impulsive decisions and promote savings discipline. To delve deeper into market mechanisms and strategies suitable for beginners, the stock market guide from Objectif Finance details these concepts in a structured manner.

The trap is not limited to timing. Confirmation biases (only reading analyses that support one’s position) and overconfidence after some initial gains lead to concentrating a portfolio on too few stocks or sectors. Diversification, often cited as a basic principle, is practically abandoned as soon as the investor believes they have identified “the right stock.”

PEA, life insurance, securities account: choosing your investment wrapper in the stock market
The choice of tax wrapper determines both the tax treatment, the universe of accessible securities, and management flexibility. Three wrappers dominate the French landscape.
- The PEA (Plan d’Épargne en Actions) offers a tax exemption on capital gains after five years of holding, but limits investment to European stocks and certain eligible ETFs. It is the reference wrapper for long-term stock investment.
- Multi-support life insurance allows access to equity funds, ETFs, and bonds, with a favorable tax framework after eight years. It also facilitates the transfer of capital.
- The ordinary securities account (CTO) imposes no geographical or product restrictions, but taxation applies from the first euro of gain. It is suitable for those who want to invest outside Europe or in products not eligible for the PEA.
For a beginner, opening a PEA first allows one to “take date” for tax purposes. Even with a modest deposit, the five-year countdown begins. Life insurance can complement this strategy for the bond portion or for inheritance.
Visible fees and hidden fees
The brokerage fees displayed by platforms represent only part of the actual cost. The annual management fees of funds or ETFs weigh more heavily over the long term than one-time transaction fees. An index ETF generally has management fees that are much lower than those of an actively managed fund. Over a long investment period, this fee gap can represent a significant difference in the final capital.
Index ETFs and direct stocks: what strategy to start in the stock market
Two approaches coexist. Investing in individual stocks requires time, skills in financial analysis, and the ability to withstand the volatility of a single stock. Investing through index ETFs replicates the performance of an entire market (or sector) with a single product, ensuring immediate diversification.
A broadly diversified index ETF remains the most suitable entry point for a beginner. It does not require following the quarterly results of each company, nor deciding when to buy or sell a particular stock. Management boils down to regularly funding one’s investment plan.
However, this passive approach does not protect against general market declines. An ETF replicating a broad index will drop as much as that index during a correction. The risk of capital loss exists over any duration, even long. Available data do not guarantee that a bull market over past decades will replicate itself identically.

Regulation and protection of beginner investors in 2024-2025
The regulatory framework has evolved. The European Securities and Markets Authority (ESMA) issued warnings in 2023-2024 after noticing that several major European brokerage platforms were aggressively promoting speculative products (CFDs, complex options) to beginners. Fines and warnings have been issued.
This regulatory pressure has led to two concrete changes:
- Brokers must now apply stricter suitability tests before allowing access to complex products. A beginner declaring little experience will be denied access to CFDs or options on certain platforms.
- Standardized warnings about the risks of rapid loss must be prominently displayed when opening an account and on product pages.
- Programmed investing in ETFs, offered by default by several neo-brokers, fits into this protection logic, guiding beginners towards less risky products than active trading.
What regulation does not cover
These protections only apply to regulated platforms. Offers disseminated via social media, paid training promising quick returns, and platforms not registered with the AMF or ESMA fall outside this framework. Checking the broker’s authorization with the regulator remains a preliminary reflex before opening any account.
Starting in the stock market with a programmed investment plan on an index ETF, housed in a PEA, while checking fees and the broker’s authorization, constitutes a solid foundation. The rest, the selection of stocks, sector analysis, active management, requires a level of skill and time that the majority of individual investors do not have, and which AMF data confirm as counterproductive for most of them.
