What is Material Non-Public Information (MNPI)?

Material non-public information, or MNPI, refers to important information about a publicly-traded company that has not been released to the general public. Trading stocks or securities based on MNPI is illegal and considered insider trading. For information to be considered "material," it must be the type of information that an investor would reasonably want to know before deciding whether to buy, sell or hold a company's securities. If the information could potentially affect the price of the stock, it is likely material.

Some examples of material information include:

  • Upcoming earnings reports or financial results

  • Anticipated mergers, acquisitions or divestitures

  • New major contracts, products or discoveries

  • Changes in senior management

  • Cybersecurity incidents or data breaches

  • Government investigations or regulatory actions

The "non-public" part of MNPI refers to information that has not been widely disseminated to investors through authorized means like company press releases, filings with regulators or news media reports. Essentially, MNPI gives certain investors an informational advantage over others in the market.

Why MNPI Matters for Investors

Having early access to MNPI allows investors to profit unfairly by trading a stock before the broader market becomes aware of price-sensitive news. This undermines market integrity and fairness. Insider trading based on MNPI is illegal under U.S. securities laws and can result in substantial criminal and civil penalties including fines and potential jail time. Even passing along MNPI to others who then trade on it, known as "tipping," is prohibited.

Examples of MNPI Situations

To illustrate what constitutes MNPI, here are some example scenarios:

  • You work at a major retailer and hear from an executive that the company expects a much lower profit in the upcoming quarter due to softening sales. This would qualify as material and non-public information.

  • Your neighbor mentions she is serving on the board of a biotech company that just had a new drug approved by the FDA before any public announcement. This too is MNPI you cannot trade on.

  • At a family dinner, your uncle who is the CFO at a public manufacturing company accidentally lets slip that the company is planning a large acquisition soon. You cannot act on this inside information.

The smartest approach for investors is to avoid trading at all if you have any reason to believe you may be in possession of MNPI. If you inadvertently receive MNPI, do not pass it along and wait until the information has been properly disclosed publicly before trading.

Identifying MNPI Isn't Always Clear

While the examples above illustrate clear-cut cases of MNPI, in the real world determining what constitutes material non-public information isn't always black and white. There can be gray areas that require careful analysis. For instance, does overhearing a vague rumor about potential bad news at a company constitute MNPI if those rumors haven't been verified? What if an employee shares general thoughts about how business seems to be going based on their limited vantage point - is that material? The materiality of information depends on the specific facts and circumstances. Information that seems vague or immaterial on its own could become material when combined with other data points or analyzed in context. To avoid any appearance of impropriety, many investors choose to simply avoid trading at all when they have any reason to question whether they may be acting on information not broadly available to the public.

Establishing Ethical Walls at Investment Firms

To prevent the misuse of MNPI, professional investment managers and stock analysts often establish "ethical wall" policies and procedures at their firms. These include:

  • Limiting data flows between public and private side operations

  • Physically separating teams that may have access to MNPI

  • Requiring disclosures of outside business activities

  • Conducting employee training on insider trading laws

  • Pre-clearing employee trades in certain securities

  • Monitoring employee computer and trading activities

Even with robust compliance programs, leaks of MNPI can still occur within organizations whether intentionally or inadvertently. This is why enforcement of insider trading laws continues to be a major focus area for regulators.

Consequences of Trading on MNPI

The consequences for insider trading can be extremely severe for both individuals and companies. Potential penalties include:

Criminal Charges:

  • Up to $5 million in fines for individuals

  • Up to 20 years in federal prison

Civil Cases:

  • Disgorgement of any ill-gotten profits

  • Up to three times the profit gained or loss avoided

  • Potential lawsuits by defrauded parties

Other Potential Consequences:

  • Bars from working in the securities industry

  • Reputational damage and loss of business

  • Loss of professional licenses or memberships

Given the serious downside risks, it's simply never worth chasing that "can't miss" stock tip or trying to game the system with confidential corporate information. Investors should stick to conducting thorough public research and letting the merits of their analysis guide investment decisions.

Investors should always be wary of soliciting or receiving stock tips from corporate insiders or those who may have access to confidential company information. While the tips may seem enticing, trading on MNPI simply isn't worth the major legal risks involved.
