It is important that all investors make informed investment decisions based on thorough research, which includes evaluating a company's disclosure and material news, as well as the price and market for the company's security.Many OTC securities can be relatively illiquid, or 'thinly traded,' which can increase price volatility. Illiquid securities are often difficult for investors to buy or sell without affecting the quoted price. In some cases, the liquidation of a position in an off-exchange traded security may not be possible within a reasonable period of time.Many equities are Penny Stocks. Penny stocks can be very risky, and investors should be aware of what type of security they are trading before making any investment decision. Due to the high level of risk involved in investing in penny stocks, a broker-dealer cannot sell them to a client unless it has approved that client's account for penny stock transactions, and the broker-dealer has received an agreement to the transaction in writing from the client. See: Penny Stock Definition, Schedule 15g. Penny Stocks are not permitted to join the OTCQX market.
