Covestor
Covestor is an online investment management platform that allows you to mirror the real trades of successful individual or Professional Investors. Launched in June 2007, it provides everyday investors access to a managed account service, previously only available to those with millions of dollars invested with a wealth management firm.
Over 500 million US dollars in securities are shared through the service, and the site has replicated 100 million US dollars' worth in trades. Its members are located in more than 100 countries and hold positions in over 10,000 different securities. All securities in mirroring accounts are purchased in the client's name and held in custody at an independent broker-dealer.
