Calculating Financial Indices

There are three main methods of calculation:

1. Price Weighting
2. Market Capitalization Weighting
3. Equal Weighting

Price Weighting

This method involves calculating the index value based on the price of each component. The DJIA is an example of an index that uses this method. (The value of each holding is related to the price you pay for it)

Market Capitalization Weighting

Here, the index value is calculated based on the market capitalization of each component. The S&P 500 uses this methodology. (The value of each holding is related to the overall holding it occupies in the index)

Equal Weighting

This method gives all components equal weight regardless of their price or market capitalization. (Every holding is equal to 1% if the index tracked 100 stocks)

Financial Indices Around the World

Besides the United States, indexes are critical in global markets. Here are a few notable international indices:

• FTSE 100 (UK)
• DAX (Germany)
• CAC 40 (France)
