## What is a weighted index number

Similarly, weighted index number can be constructed either by (i) weighted aggregative method, or by (ii) weighted average of price relative’s method. The choice of method depends upon the availability of data, degree of accuracy required and the purpose of the study. A price-weighted index is a stock market Index in which companies’ stocks are weighted according to their share price. A price-weighted index is mostly influenced by stock which has a higher price and such stock receives greater weight in the index regardless of companies issuing size or number of outstanding Shares. Index number for 1995 = 87.00/69.00 * 100 = 126.1. Difference between base-weighted and current-weighted indices. Neither is perfect. Base-weighted indices are simple to calculate but they tend to overstate changes over time. Current-weighted indices are more complex to produce and they understate long-term changes.

In this index number the current (given) year quantities are used as weights, so it is also called the current year weighted index. Fisher’s Ideal Index Number. The geometric mean of Laspeyre’s and Paasche’s index numbers is known as Fisher’s ideal index number. Unlike simple index numbers, weighted index numbers, as the name suggests, weigh items according to their importance with respect to the concerned variable. For example, when calculating the price index number if the price of a unit of rice is twice the price of a unit sugar then the rice will be weighed in as ‘2’ whereas sugar will be weighed in as ‘1’. A capitalization-weighted index is a type of market index with individual components, or securities, weighted according to their total market capitalization. Market capitalization uses the total market value of a firm's outstanding shares. The calculation multiples outstand shares by the current price of a single share. The index number that is computed after assigning due weightage to different items under study is called weighted index number. In such a case, weights are assigned in an explicit manner either on the basis of the quantities, or on the basis of the values of the items consumed, or on any other rational basis. A value-weighted index assigns a weight to each company in the index based on its value or market capitalization. Follow the example and you will learn how a value weighted index number is In the case of a value-weighted index, the amount of outstanding shares comes into play. To determine the weight of each stock in a value-weighted index, the basic formula (without getting too complex for demonstrative purposes) is to multiply the price of the stock by the number of outstanding shares.

A price-weighted index is a stock market index where each stock makes up a fraction of the index that is proportional to its price per share.
