New rules will affect your ability to buy and sell “Pink No Information” securities, including at E*TRADE
On September 28, 2021, new requirements take effect that will impact the market for—and value of—certain “over-the-counter (OTC) securities” you currently hold or have held in the past. The new rules apply to “Pink No Information” OTC securities of companies that fail to publicly report and keep current financial and other company information and will restrict the ability of U.S. brokers, like E*TRADE from making these products generally available.
