Adjustment factors can be used for many purposes including –
Adjusting historical prices for display as a chart. Looking at the picture below, the adjusted chart is much clearer than the unadjusted chart. The unadjusted chart has a large jump in the prices on the effective date.

Another reason for using adjusted prices is that they include the value of the event that caused the adjustment. For example -
Comparing the unadjusted prices implies that no money has been made from the investment, however comparing the adjusted purchase price implies that a 20% return has already been realised from the investment (i.e. the dividend has been “factored” into the purchase price).
Previously it has been difficult to know when to apply adjustment factors and what the factor should be.
The Adjustment Factor service solves both the above two problems ~ you will be advised when to apply and what to apply. The feed is available either via FTP or via our website.
You can subscribe to this service on an exchange-by-exchange basis or as an overall package for all exchanges.
