The SEC issued an Investor Bulletin about investing in companies that enter U.S. markets through so-called “reverse mergers.” 

Reverse Mergers ... permit private companies, including those located outside the U.S., to access U.S. investors and markets by merging with an existing public shell company. 

The SEC and U.S. exchanges recently suspended trading in a more than a dozen reverse merger companies, citing a lack of current, accurate information about these firms and their finances.

“Given the potential risks, investors should be especially careful when considering investing in the stock of reverse merger companies,” said Lori J. Schock, Director of the SEC’s Office of Investor Education and Advocacy. “As with any investment, investors should thoroughly research the company – including ensuring there is accurate and up-to-date information – before making a decision to invest.”
