Introduction to Buying Stocks in 2025

Before diving into buying stocks, it is essential to understand the basics of the stock exchange and the financial market.

Investing in stocks allows participation in economic growth but also involves inherent risks associated with the markets.

What is a Stock?

A stock is a property title issued by a publicly traded company. By purchasing a stock, you become a partial owner of the company and can, according to the share held, influence its governance (right to vote at general meetings) and receive a portion of the profits in the form of dividends. Stocks are traded on specific markets with strict transparency rules.

Stocks generally reflect the health of the company but are also influenced by the economic context, industry trends, and supply and demand levels on the markets.

The Stock Exchanges

Stock exchanges are the venues where financial securities are traded: stocks, bonds, ETFs, etc. The largest global stock exchanges are the New York Stock Exchange (NYSE), the NASDAQ (specialized in technology), the London Stock Exchange, and the Euronext Paris for France and Europe.

Paris Stock Exchange (Euronext Paris): main stock market in France
NASDAQ: US market focused on technology
NYSE: largest global market capitalization
London Stock Exchange: leading European market
Other regional or specialized markets: Frankfurt, Milan, Madrid...

Diversification Through ETFs and Index Funds

Exchange Traded Funds (ETFs) are diversified baskets of stocks or other assets, traded in real-time and replicating the performance of an index or sector. They represent an ideal tool for diversifying investments and reducing the risk associated with a single company.
