Additional - what is the meaning of Homemade Dividend?
For example if a stockholder owns 1000 shares, he can sell 10 shares to receive money equal to 1% dividend. After the sale the value of his stocks will be 1% less, but that would have been the same if the company had declared 1% dividend, because that also reduces the stock price.
