As per the discussion paper of SEBI on margin trading and securities lending, this form of trading is executed in view of the foreseen market outlook, wherein investors are facilitated to trade in certain securities with borrowed resources (funds and securities), without entirely self-owned funds. However, in the process, traders are required to maintain a minimum margin amount for the proposed transaction with the depository as good-faith deposits. Further, the margin amount is usually a percentage of the total transaction amount which is generally 15-20%, however it differs from scrip to scrip.

For instance: If an investor wishes to buy 100 shares of an X scrip trading at Rs 200, he can opt for the margin trading route, wherein the transaction would be partly funded by the trader (margin money) and partly by the broker (borrowed funds).

Margin trading proves to be a leverage mechanism for investors as they are allowed to perform trading with margin money. From the investor's stance, margin trading provides comparably larger exposure with a relatively smaller margin amount. In this way, chances of realizing higher profits or losses is increased.
