What is a Stock Market Index?
- A Stock Market Index is a weighted average of a number of stocks, from a section of a Stock Market
- A Stock Market Index is calculated from the price of the selected stocks, usually a weighted average
- A Stock Market Index is supposed to reflect an entire Stock Market and track the entire market over time
What are the types of indices?
The index may reflect anything from a global overview of stocks or a country specific sector.
- Global and World Indices e.g. MSCI World
- Regional Indices e.g. S&P Asia 50
- National Indices e.g. FTSE 100 (for the UK)
- Sector Indices e.g. Banking
How are indices calculated?
There are two main ways of calculating a stock index
The Price of a Stock is the determinant of the Weighting in the Index e.g. Dow Jones Industrial Average
Factors in the Size of the Company, that is the Capitalization of the Stock e.g. S&P 500, FTSE 100
