How Does It Work?

There are numerous approaches to calculate an index. An index based solely on stock prices is called a \price weighted index.\ This sort of index ignores the significance of any particular stock or the company size.

A \market value weighted\ index, on-the other hand, takes into account the size of-the organizations concerned. Like that, price shifts of small companies have less influence than those of larger companies.

Another type of index may be the \market share weighted\ index. This type of list is based on the number of shares, in place of their full value.
