38 Facts About Indices

What Are Indices?

Indices, or indexes, are statistical measures that track changes in the economy or financial markets. They help investors understand market trends and make informed decisions. Here are some fascinating facts about indices.

1. The Dow Jones Industrial Average (DJIA) is one of the oldest and most well-known indices, established in 1896.

2. Indices can be broad or specific. For example, the S&P 500 tracks 500 large companies, while the Nasdaq-100 focuses on 100 of the largest non-financial companies listed on the Nasdaq stock exchange.

3. Indices are used as benchmarks. Investors compare their portfolio performance against indices to gauge success.

4. Indices can be price-weighted or market-cap weighted. The DJIA is price-weighted, meaning companies with higher stock prices have more influence. The S&P 500 is market-cap weighted, where larger companies have more impact.

5. Global indices exist. The MSCI World Index includes companies from 23 developed countries, providing a global market snapshot.

How Indices Are Calculated

Understanding how indices are calculated helps in grasping their significance. Different methods can lead to varying results.

6. Price-weighted indices add the prices of all stocks and divide by a divisor. This method is simple but can be skewed by high-priced stocks.

7. Market-cap weighted indices multiply the stock price by the number of shares outstanding. This method reflects the company's overall market value.

8. Equal-weighted indices give each stock the same importance, regardless of size. This approach can highlight smaller companies' performance.

9. Fundamental-weighted indices use financial metrics like earnings or dividends to determine weight. This method focuses on company fundamentals rather than stock price.

10. Float-adjusted indices consider only shares available for public trading, excluding insider holdings. This approach aims to reflect the actual market more accurately.

Popular Indices Around the World

Different regions have their own key indices, each reflecting their unique markets and economies.

11. The FTSE 100 represents the 100 largest companies on the London Stock Exchange.

12. The Nikkei 225 tracks 225 large companies on the Tokyo Stock Exchange.

13. The DAX 30 includes 30 major companies on the Frankfurt Stock Exchange.

14. The CAC 40 covers 40 significant companies on the Euronext Paris.

15. The Hang Seng Index follows 50 large companies on the Hong Kong Stock Exchange.
