No. Once it’s public it’s public. It’s actually incredibly difficult to get charged and convicted of insider trading. It has to be really blatant.
If I remember correctly, 2 things need to be proven: 1) someone shared non-public information they shouldn’t have, 2) there was some consideration (money, etc) given for such information.
So there are cases where #2 becomes the issue because no money changed hands. Then the argument can get weird where the argument is “he offered the insider information in exchange for friendship”.
