  • A Stock Market Index is a weighted average of a number of stocks, from a section of a Stock Market

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

  • Sector Indices e.g. Banking

How are indices calculated?

There are two main ways of calculating a stock index

  • Price-Weighted
  • Capitalized-Weighted


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
