In 1909, the Supreme Court of the United States ruled in Strong v. Repide[20] that a director who expects to act in a way that affects the value of shares cannot use that knowledge to acquire shares from those who do not know of the expected action. Even though in general, ordinary relations between directors and shareholders in a business corporation are not of such a fiduciary nature as to make it the duty of a director to disclose to a shareholder the general knowledge which he may possess regarding the value of the shares of the company before he purchases any from a shareholder, yet there are cases where, by reason of the special facts, such duty exists.
