which company has announced highest dividend for its sharholders?

Answer 1

Often a dividend-paying company will get into trouble, and its stock will drop quite a bit. Then the data sources such as Yahoo list the dividend rate and it looks huge, although the company may never actually pay that dividend.

I don't know who has the highest rate at the moment.

For large, relatively safe dividends, consider the Canadian Royalty Trusts, such as for oil and gas production. Also, look into oil shipping companies such as Frontline.

Best of success.
