Sure so insider trading is almost exclusively a creature of the executive branch, with the general antifraud provision under “Section 10b-5” used to prosecute it most of the time, a provision only the securities regulatory can pursue (in conjunction with DOJ for the criminal prong)
The legislature fails to have consensus on this topic and hasn’t weighed in since the 1980s (where it was only to add statutory damages if a conviction was achieved, but no clarity regarding how and when it could be achieved)
And courts strip or uphold nuances various of the agency’s sentiment leaving this to be largely unsettled territory, all while the people that staff these agencies have the same unclear and misguided (when courts later disagree) view on what kind of trading is or isnt prohibited
Other markets are completely exempt: Futures, currencies, metals, nike shoes, non-securities digital assets. I think this aberration for the securities market should be re-evaluated, as it is an expensive dragnet.
