A penny stock typically refers to a stock that trades for less than $5 per share. This type of stock normally has high price fluctuation, low liquidity, and a higher chance of delisting. Normally we do not suggest public investors trade penny stocks.
Penny stock is a type of stock, and its trading process, trading hours, and order types are the same as those of common stock.
Warm reminder: Because of the high risk, if it is your first time to trade penny stocks, you need to confirm the risk disclosure before you can trade them.
When the price of US stocks falls below $5, they are considered penny stocks. If you open new positions in these US stocks, you need to confirm the risk, but there are no restrictions on closing positions.
Generally, short selling of penny stocks is not restricted. Please note that, from the perspective of risk management, Moomoo Financial Inc.may adjust the short-selling limits and short margin rates of some penny stocks from time to time.
Since there is no daily price limit on US stocks, prices of penny stocks may fluctuate greatly within a day.
Penny stocks lack a liquid market with low trading volume, and thus have high liquidity risk.
The delisting risk of penny stocks is greater than that of common stocks.
