Government regulators want to ensure that stock trading is fair. When people have material non public information, that may give them a trading advantage to buy or sell and consequently, that isn't allowed. As a result, employees, officers, or directors of public corporations or people with access to this type of information is not allowed to directly own stock in that company.
When you onboard, we will ask you if there are any stocks you may not hold and exclude that from our trading algorithm.
