Opening a first securities account or a PEA without knowing where to invest your money is the situation faced by several hundred thousand French people each year. In 2025, France had 3.8 million individual investors, including 780,000 new entrants, representing a 51% increase compared to the previous year. Starting in the stock market in this context requires laying solid foundations before placing any orders.
Choosing your tax wrapper before selecting your stocks
We often see beginners rushing to a mobile app to buy their first stocks without considering the tax framework. The choice between PEA, ordinary securities account, life insurance, or PER determines the taxation applied to gains for years.
The PEA remains the logical starting point for a French tax resident. After five years of holding, capital gains and dividends are exempt from income tax (social contributions remain due). The contribution limit is set at 150,000 euros, which provides ample room to build a long-term portfolio.
The ordinary securities account offers access to all global markets, without geographical restrictions, but each gain is subject to a flat tax rate. It is reserved for American stocks or products not eligible for the PEA. Life insurance, on the other hand, combines management flexibility with decreasing taxation after eight years. To delve deeper into each wrapper and compare strategies suitable for beginners, the stock market section on Aujourd’hui J’investis details these mechanisms with concrete cases.
The 2025 report from the AMF mediator also notes a record increase in disputes related to PEA transfers between institutions. Before opening a PEA with a broker, one should check the outgoing transfer times and associated fees, as a blocked PEA during a transfer prevents any operations for several weeks.
ETFs and systematic investment: the strategy that works for a first portfolio
Buying individual stocks when starting out is betting on one’s ability to analyze financial statements without training. ETFs (exchange-traded funds) solve this problem by replicating an entire index, such as the CAC 40 or the MSCI World, for very low management fees.
One single global ETF diversifies a portfolio across hundreds of companies spread over several geographical areas. This reduces the specific risk associated with a single company while capturing the overall performance of the markets.
The most suitable method for beginners remains systematic investment: an automatic monthly transfer to their PEA or life insurance, with regular purchases of the same ETF. This regularity smooths the purchase price over time and neutralizes the urge to “buy at the right time,” a trap that can be costly even for professionals.
- Define a monthly amount compatible with one’s budget, without touching emergency savings (a few months of regular expenses in a savings account)
- Select one or two physically replicating ETFs, eligible for the PEA, with sufficient assets to ensure liquidity
- Automate the purchase to eliminate hesitation and market timing
- Avoid checking the portfolio every day; a quarterly review is sufficient
Social media and neo-brokers: the biases that trap beginners in the stock market
The AMF 2025 barometer highlights a recurring pattern: investors under 35 make more decisions based on content seen on social media than on the analysis of a company’s fundamentals. Neo-brokers, with their gamified interfaces and push notifications, amplify this bias.
This is not a theoretical risk. The AMF warned in 2026 against fraudulent platforms using mass scam methods, specifically targeting new investors attracted by promises of quick returns.
Three reflexes protect a beginner’s capital:
- Always check that the broker or platform has an AMF approval or a valid European passport
- Ignore any promise of guaranteed returns; investing in stocks always carries a risk of capital loss
- Distinguish sourced financial information (annual reports, regulatory documents) from opinions posted on TikTok or Instagram by unregulated creators
Feedback varies on this point, but several testimonies relayed by the AMF mediator show that beginners have lost their entire investment on unapproved platforms discovered through social media advertising.
Risk management and investment horizon: what distinguishes an investment from a bet
Money invested in the stock market should not be used to pay next month’s rent. This simple rule separates investment from betting. One should only invest money that is not needed in the short term, ideally over a minimum horizon of five years.
Market volatility is normal. A diversified ETF portfolio can significantly lose value over a few months, then recover over one or two years. Selling in a panic crystallizes the loss. Staying invested allows one to benefit from rebounds and, in the long term, from the historical upward trend of stock markets.
In practice, one adjusts the allocation between stocks and bonds according to their profile. A 25-year-old investor with a long investment horizon can tolerate a high exposure to stocks. At 55, with a retirement project approaching, gradually reducing the equity portion protects the accumulated capital.
The PER (retirement savings plan) makes sense in this second case: contributions are deductible from taxable income, and the capital remains locked until retirement, enforcing long-term investment discipline.
Starting in the stock market does not require a significant starting capital or expertise in financial analysis. A PEA, a diversified ETF, an automatic monthly transfer, and the patience not to touch one’s portfolio for several years provide a stronger foundation than any tip found on a news feed.
