Hypothetically, would being the 8th largest individual shareholder of MSFT be large enough compensation to make a fiduciary suit an acceptable cost of doing business?
In some places breach of fiduciary duty is a criminal offense. So you may very well end up in jail.
I'm not sure there is adequate compensation for a risk like that. Being the 8th largest shareholder of MSFT might do the trick for some individuals but that's just another version of 'every man has his price'. For me I hope I'll never learn mine.
