Defining a Market Value Weighted Index
In the investment world, a market value weighted index is a type of index that represents the performance of a group of stocks, bonds, or other assets. The weight of each asset in the index is based on its market value, which is the price of the asset multiplied by the number of outstanding shares or units. The result is an index that is heavily influenced by the performance of the largest assets in the group.

History and Significance
Market value weighted indices have been used for decades to track the performance of stock markets around the world. The first such index was the Dow Jones Industrial Average, which was created in 1896. Other well-known market value weighted indices include the S&P 500, the Nasdaq Composite, and the FTSE 100.
These indices are important because they provide investors with a benchmark against which to compare their own investment performance. They also serve as a barometer of the overall health of the economy and can be used to make investment decisions.
Calculating a Market Value Weighted Index
Calculating a market value weighted index is a relatively straightforward process. The first step is to determine the market value of each asset in the group. This is done by multiplying the price of the asset by the number of outstanding shares or units.
Once the market values of all the assets have been determined, the next step is to calculate the total market value of the group. This is simply the sum of the market values of all the assets.
The final step is to calculate the weight of each asset in the index. This is done by dividing the market value of the asset by the total market value of the group.
The weights of the assets in the index will sum to 1.0. The weight of an asset represents its importance in the index. The larger the weight of an asset, the greater its influence on the index’s performance.
