In actuality, who knows? But the rational for it isn’t fairness, but rather theft. If I work at WalMart and I trade on insider information (let’s say I work on a deal team negotiating to buy a company for WalMart), I’m stealing from my employer, which arguably creates bad incentives. In my opinion insider trading should be a civil issue, but the big corps have successfully convinced the government to take up arms on their behalf under the populist guise of fairness.
