Unless it's the principals of either business it can be difficult to identify insider trading.

I have read that if the SEC deems the insider trading to be serious they will investigate immediate family members, relatives, friends,indirect business associates, and even neighbors of those who possessed privy information. But mostly, as in Martha Stewart's conviction, it needs to be sizeable and include a witness who can be compelled to testify. Stewart was convicted because a person was in the car with her when she received a call from an executive advising her to sell. The fellow passenger testified against her.
