OTC stocks
OTC stocks are not listed on the major exchanges, they are instead traded directly between two parties in a decentralised market.
For example, if a company stock gets delisted, it may begin trading OTC. To learn more about stock delisting, visit this FAQ.
Stocks that trade via OTC are commonly smaller companies that don't meet the exchange listing requirements of formal exchanges.
OTC stocks can be riskier, more volatile, and illiquid (harder to convert into cash). The price displayed in-app is indicative only, and market orders may execute at a different price.
Trading OTC may be one of the reasons a stock can be restricted to selling only. To learn more about 'sell only' stocks, visit this FAQ.
