In the meantime, instances the place the insider can affect the result, reminiscent of a politician betting on their very own marketing campaign, ought to have essentially the most enforcement.
“Buying and selling on a real, independently researched edge is the exercise society needs to be most reluctant to punish […] And buying and selling by those that can transfer the result warrants the stiffest enforcement, as a result of their positions invite manipulation.”
