The Nikkei Stock Average Dividend Point Index is an index that accumulates dividends received from the companies when investors are supposed to hold the constituents of the Nikkei Stock Average (Nikkei 225) on a calendar year basis, i.e. January to December in a year. The index is calculated by substituting each actual dividend per share into the formula of the Nikkei 225 every time the each dividend value is fixed. Its final index value of the year is published at the beginning of April in the subsequent year after the all dividend payments of the constituents are fixed. The index is expressed with a year such as the Nikkei Stock Average Dividend Point Index (2011) since the index is calculated by accumulating the dividends every calendar year basis. The index value of the previous year is displayed until 1st business day of April, and the index of the current year is displayed from the 2nd business date of April on this page.
