SEC Rule 10b5-1 information links
The SEC released Rule 10b5-1 in October 2000, in part to deter insiders from trading while in possession of material nonpublic information. The rule specifically makes trading while in possession of material nonpublic information illegal. The rule also provides an affirmative defense against litigation to insiders who preplan trades when they do not possess material nonpublic information.
