Jan option holders
You've got NO recourse. There are specific rules about when information must be disclosed. Three business days. IDCC met that requirement. Unless there is evidence that they delayed the announcement to benefit themselves because they sold options (no way), there is nothing to pursue.
IDCC did nothing illegal. They did nothing unethical or improper. Enjoy the gains on your stock holdings. If you don't have any, you're just a gambler, not an investor. Sometimes the breaks go your way and sometimes they don't. Nobody likes to listen to bad beat stories, and don't blame the dealer for turning up the winning card after you folded.
