Opening a first securities account or a PEA on a Friday evening, placing an order on a stock whose name was read on a forum, then watching the price drop on Monday morning: this is the classic scenario of a beginner in the stock market who acts before structuring their approach. Getting started in the stock market requires settling a few concrete parameters even before investing a euro in the financial markets.
Choosing your tax envelope before selecting a broker
People often start by comparing brokers, while the first decision concerns the envelope. In France, three supports coexist: the PEA, the ordinary securities account, and life insurance in units of account. Each imposes different rules on the taxation of gains, the investment universe accessible, and the withdrawal conditions.
The PEA remains the most advantageous framework for a beginner investor aiming for the long term. After five years of holding, capital gains and dividends are no longer subject to income tax. Opening a PEA as early as possible starts the tax clock, even with a symbolic deposit. The securities account, on the other hand, provides access to all global markets without a deposit ceiling, but every gain is subject to flat-rate withholding tax.
For those exploring different investment approaches, the stock market portal of Libre Finance gathers useful resources on envelopes, ETFs, and strategies suited for beginner profiles.
ETFs and scheduled investment: the combination that simplifies starting out
Recent data from the AMF shows a clear shift: ETFs have become the dominant entry point for new investors in France since 2023. The share of first-time investors going directly through ETFs (rather than individual stocks) has significantly increased.
An ETF replicates an entire index. Buying a global ETF means holding a fraction of several thousand companies in a single line. Diversification is achieved in a single order instead of twenty. Annual management fees hover around a few tenths of a percent, compared to often more than one percent for an actively managed fund.
Scheduled investment (sometimes called DCA, for Dollar Cost Averaging) involves depositing a fixed amount each month. You buy more shares when prices are low, less when they are high. Over the long term, this regularity smooths the entry price and neutralizes the reflex to want to buy at the best moment, an exercise that even professionals fail to achieve consistently.
What it looks like in practice on a PEA
- You open a PEA with an online broker offering reduced fees on ETFs (some brokers offer commission-free orders on a selection of ETFs eligible for the PEA).
- You set up an automatic monthly transfer from your current account to the PEA, even for a few dozen euros.
- You select one or two broad ETFs (global or European index) and place the order on the day of the transfer, without consulting market forecasts.
- You do not touch anything for at least five years, except for occasional rebalancing if you have multiple positions.
The hidden fees that eat into a beginner’s portfolio performance
Fees are the only investment parameter that you can fully control. A traditional broker charges brokerage fees, custody fees, and sometimes inactivity fees. An online broker often eliminates custody fees but applies currency conversion fees on securities listed outside the eurozone.
Comparing actual fees over a year for a typical beginner profile (a few orders per month, small amounts) reveals differences of several dozen euros. Over five or ten years, these compounded differences significantly reduce the final capital.
Returns vary on this point, but most retail investors also underestimate the impact of the spread (the difference between the buying price and the displayed selling price). On a very liquid ETF listed on Euronext, the spread is negligible. On an exotic ETF or a little-traded security, it can represent an implicit cost greater than the brokerage fees themselves.
Financial scams: the risk that guides often overlook
The AMF has issued multiple alerts in 2025 and 2026 about a rapidly growing phenomenon: scams disguised as press articles or investment advice. Fake emails mimicking the visual identity of the AMF, fictitious platforms presented as licensed brokers, advertisements on social media promising fixed returns.
The influx of young new investors amplifies the problem. In 2025, France had about 3.8 million unique retail investors, including 780,000 new entrants. This population, often informed via social media, is a prime target for scams.
Three checks to make before any deposit
- Consult the AMF’s blacklist (regularly updated) to verify that the platform or broker is not listed there.
- Check that the intermediary has an ACPR approval or a European passport registered with the AMF, via the REGAFI register.
- Beware of any promise of guaranteed returns: no investment in stocks or ETFs guarantees a fixed return.
The AMF notably warned against the platform Bit Kel Trade in August 2026, describing its methods as a mass scam. The scheme is always similar: a reassuring first contact, fictitious gains displayed on an online dashboard, then the inability to withdraw funds.
A beginner investor who masters their tax envelope, automates their contributions to diversified ETFs, controls their fees, and verifies the legitimacy of each intermediary covers the vast majority of costly mistakes. The rest, the fine selection of indices, the arbitration between geographical areas, the addition of bonds, comes naturally with months of practice and the first portfolio statements.
