M1 supports most common stocks, ETFs, and CEFs listed on the supported exchanges. However, due to the nature of the trading algorithm, M1 can only support actively traded securities. M1 has volume requirements for all of its supported securities. If a supported security falls below M1's required threshold, that security will be removed from the list of securities that M1 supports. If you own this security in your portfolio, you will be contacted by our support team to request you to remove that security from your target allocation. No trading on your account will occur until the security is removed. After the security is removed, automatic trading will resume and that position will be liquidated during the next trading window.
