Margin trading and short selling are financial derivatives that allow traders to buy or sell securities by using borrowed funds or selling securities they do not own. Margin trading allows traders to use a small amount of their own funds to execute large transactions, while short selling allows them to profit from the decline in the price of securities. However, margin trading and short selling come with greater risks. Margin trading refers to the purchase of securities using funds borrowed from a brokerage firm, while the seller of a short position profits from a decline in the price of securities they have sold but do not own.
