Required documents: ID, proof of address (less than 3 months), bank statement, and MIF questionnaire evaluating your financial skills.

Avoid These Mistakes at All Costs
⚠️ Warning: Buying stocks on the stock market involves risks. Here are the most common mistakes that can cost novice investors dearly.
1. Following Trends and "Tips"
Social media is full of unverified advice. Meme stocks, volatile cryptocurrencies, and other viral phenomena may seem attractive but are often traps. Always prefer rigorous analysis based on factual data.
2. Neglecting Risk Management
Never invest more than 5% of your capital in a single stock, even with the greatest conviction. Automatic stop-loss orders are your friends for limiting potential losses.
3. Market Timing
Trying to buy at the lowest point and sell at the highest is illusory. Even professionals do not always succeed systematically. Regular investment and patience remain the best strategies.
Tax Aspects and Optimization
Taxation of Capital Gains
Understanding taxation is crucial when you want to buy stocks on the stock market. In France:
- Stock Account: Flat tax of 30% (17.2% social security contributions + 12.8% income tax)
- PEA: Exemption from tax after 5 years of holding (only 17.2% social security contributions)
- Deduction for Holding Period: Possible in certain specific cases
Legal Tax Optimization
Several strategies allow you to optimize the taxation of your investments:
- Prefer the PEA for eligible European stocks
- Spread sales over several civil years
- Offset gains and losses in the same year
- Use life insurance as a complement for diversification

Investor Psychology
Buying stocks on the stock market is not just a technical issue, it is primarily a psychological challenge. Cognitive biases are the first enemies of performance:
- Confirmation Bias: Seeking only information that confirms our beliefs
- Herd Effect: Following the crowd rather than one's own analysis
- Aversion to Losses: Holding onto losing positions too long
- Overconfidence: Overestimating one's abilities after a few wins
💡 Solution: AI tools eliminate emotion from the equation. By relying on objective algorithms and quantifiable data, you make rational decisions rather than emotional ones.
