Why is Most Insider Trading Against the Law?

Most insider trading is illegal because it gives an unfair advantage to the person or people with inside information. If everyone had access to the same information, then trading would be based on who could make the best investment decisions, rather than who had access to information that others didn’t have.

In the United States, federal and state securities laws prohibit insider trading. Insider trading is generally defined as trading in a company’s stock by individuals with access to material, nonpublic information about the company.

Federal insider trading law is contained in Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder. These provisions make it unlawful to use or communicate material, nonpublic information in connection with the purchase or sale of a security.

State laws prohibiting insider trading are patterned after federal law. In addition, a number of states have adopted their own insider trading statutes. These state statutes are generally broader than federal law in that they may apply to persons who are not insiders of the company and they may prohibit the use or communication of nonpublic information even if there is no intent to defraud.

There are a number of defenses to insider trading charges, including the following:

– The information was not material.
– The information was not nonpublic.
– The individual did not trade on the basis of the information (that is, he or she traded before learning of the information).
– The individual did not communicate the information to anyone else (that is, he or she did not tell anyone else about the information before trading).

What is insider trading?

Insider trading is generally defined as trading in a security while in possession of material, nonpublic information about the security. It can also include tipping others off to insider information so they can trade on it before it becomes public. Both insider trading and tipping are illegal.

There are a few legal exceptions to the rule against insider trading, such as when an insider trades on information that is considered general market information or when the insider has no material, nonpublic information but trades based on a strong hunch. These legal exceptions are very narrowly defined, however, and most insider trading activities fall outside of them.

The U.S. Securities and Exchange Commission (SEC) is the government agency responsible for enforcing laws against insider trading. The SEC investigates possible cases of illegal insider trading and can bring civil or criminal charges against violators.

Why is most insider trading illegal?

Most insider trading is illegal because it violates the fiduciary duty that corporate insiders — officers, directors, and significant shareholders — owe to their corporation’s shareholders. These corporate insiders have access to material, nonpublic information (“inside information”) that, if used for personal gain, can distort the marketplace and, as a result, harm ordinary shareholders who do not have access to such information.

What are the exceptions to the rule?

First, it’s important to understand what is considered insider trading. Generally speaking, insider trading is any kind of trading that uses insider information to make a profit. This information can be material, non-public information about a company that gives the trader an advantage over other investors who don’t have this information.

Now, there are some exceptions to this rule. For example, if you are an employee of a company and you purchase stocks in that company through your employer’s stock plan, that is not considered insider trading. Another exception is if you purchase shares in a company that is about to go public (an “IPO”). In these cases, the inside information is considered to be publicly available and not giving the trader an unfair advantage.

So, why is most insider trading against the law? The simple answer is that it’s unfair. Imagine if you had material, non-public information about a company and you used it to make a profit while everyone else was left in the dark. That would not be fair to the other investors and it would give you an undue advantage in the market.

Insider trading can also harm the markets overall. If people believe that insider trading is rampant, they may be less likely to invest in the stock market because they don’t feel like it’s a level playing field. This can lead to less liquidity and stability in the markets, which is why regulators take insider trading so seriously.


In conclusion, most insider trading is illegal because it violates the fiduciary duty that corporate insiders owe to their shareholders. Corporate insiders are not allowed to use their non-public information to gain an unfair advantage in the stock market. If they do, they can be subject to civil and criminal penalties.
