What are Stock Indexes?

Stock indexes are groups of stocks that represent the performance of a market, sector or economy in general. They function as financial thermometers, showing whether the market is rising or falling.

Each index is made up of a set of companies and is calculated based on market capitalization, stock price, or a combination of both.

Simple example:

📈 If the S&P 500 is up, it means that most of the 500 largest U.S. companies have risen in value.

World's most important indexes

🔹 S&P 500 (U.S.): Includes 500 of the largest companies, such as Apple, Microsoft and Tesla.

🔹 Dow Jones (USA): Measures the performance of 30 industrial giants such as Coca-Cola and Goldman Sachs.

🔹 NASDAQ 100 (U.S.): Represents technology companies such as Google, Amazon and Meta.

🔹 FTSE 100 (UK): Encompasses the top 100 British companies.

🔹 DAX 40 (Germany): The 40 largest companies in the German economy.

🔹 Nikkei 225 (Japan): Represents the Tokyo stock exchange with giants such as Sony and Toyota.

Each index reflects the state of the market in its country or sector, making them key tools for investors.

Why invest in Stock Indices?

Less risk, more stability - Instead of buying one stock, you invest in an entire market.

✅ Automatic diversification - Protect your capital by including several companies in a single investment.

✅ Long-term strategy - Indexes tend to rise over time, reflecting economic growth.

✅ Low maintenance - You don't need to analyze each stock, just follow the trend of the index.

📊 Example:

If you had invested in the S&P 500 in 2000, your investment would have tripled in 20 years. 🚀
