Well just to be complete there are enumerated duties to shareholders (the fiduciary ones):

1. Duty of Care

2. Duty of Loyalty

3. Duty of Disclosure

4. Duty of Confidentiality

5. Duty of Prudence

6. Duty of Good Faith

P.S. Just a (fly-by)comment; not advice of any short or kind -- either investment or legal. P.S.2 Oh it does happen that share/stake holders seek enforcement for breach of fiduciary duties. I would say it is quite common.
