When shares are sold or issued, they increase the stockholders equity as people buy these shares. They also increase assets because cash comes into the company when the shares are sold. This is why the Issuing of preference and common stock as well as the sale of Treasury shares had the same effects.
When cash dividends are declared, they become a liability that is owed to equity holders.
When these dividends are then paid, they remove the liability but reduce assets as cash is used to pay the dividends.
100% stock dividend reduces retained earnings but increases equity so stockholders equity does not change.
