Insider trading consists of an individual who is an insider to a company that is publicly traded, trading stock in that company on information they obtained as an insider.
> When Warren Buffett decides that he wants to buy stock in a company, he knows that if this became public, the target company's stock would go up.
Warren Buffett is not a publicly traded company, and in this hypothetical he is buying stock in another company, which (by assumption) he has no insider information about.
> Insider trading law in the US is about breaching fiduciary duty.
This is false. It's about protecting traders. This is why it applies specifically to publicly traded companies. If it was about protecting shareholders (from what?) then it would apply to all companies.

No, that's not true in US law. It doesn't have to be the stock of the company you work for to get you into insider trading trouble.

Well, that's why your definition is wrong.

Huh, what? You don't have a fiduciary duty to people you don't work for.

> The rationale for this prohibition of insider trading differs between countries and regions. Some view it as unfair to other investors in the market who do not have access to the information, as the investor with inside information can potentially make larger profits than an investor without such information.[2] However, insider trading is also prohibited to prevent the directors of a company (the insiders) from abusing a company's confidential information for the directors' personal gain.
Well, there you go. Any more questions?
