Remember this first
First, 3 things to remember
- 1It is not illegal for executives to trade their own company's stock.
- 2Trading based on the unfair use of material non-public information can be problematic.
- 3Do not assume the trader's intentions or illegality based solely on public reports.
The same term is used in two contexts.
Insider buying in the news may refer to public transaction information where company-related individuals, such as executives or directors, purchased shares. It does not mean that all insider stock trading is prohibited.
Illegal insider trading involves trades that use material non-public information in violation of fiduciary duties. It can also be an issue if a person who is not a company employee receives and uses such information.
First, distinguish whether the information is known.
There is a difference between earnings publicly announced by a company and secrets regarding major contracts not yet disclosed. Non-public information means information that is not yet available to the general public.
Specific illegality must be determined by examining the facts and rules. Do not label someone an illegal trader just because the price rose or the timing of the trade is noticeable.
We read the facts from public data first.
Check Form 4, a report on stock transactions by executives, to see who, when, and what type of transaction occurred. Distinguish between shares received as compensation and shares purchased with their own money.
Executive buying does not guarantee future price increases, and selling does not mean the company is about to fail. Distinguish between the fact of the trade and speculation about the reason for it.
You should not make such assumptions
“Since an executive sold their own company's stock, is it illegal?”
You cannot judge based solely on the fact of a sale. Actual facts such as the use of information, obligations, and transaction conditions are important.
Check what you have read.
- Did you distinguish between disclosed trade facts and the use of non-public information?
- Have you checked the transaction date and reason?
- Have you made assumptions about intentions or illegality without confirmation?
