SEBI has mandated that listed companies declare the dividend in terms of rupee per share.
When the dividend received by an investor is compared to the market price of the share, it is called the dividend yield of the share.
Buyback of shares refers to repurchase of shares by the company from its existing shareholders.
A company may issue additional shares to existing shareholders without any capital contribution from the shareholders based on the number of shares an investor holds.
A company may decide to change the face value of its shares. This is done through stock split or consolidation methods. These methods change the number of outstanding shares. However, in both the cases, the value of the shares held by a shareholder remains unchanged.
