Margin trading means buying shares with partly borrowed money. You pay a portion of the purchase price, called the margin, and your broker lends you the rest, charging interest. This lets you buy more shares than your own money alone would allow, but it also magnifies losses.
What margin trading is
Borrowing to invest creates leverage. If you buy ₹1,00,000 of shares with ₹40,000 of your own money and ₹60,000 borrowed, a 10% rise in the shares gives you a ₹10,000 gain on your ₹40,000, which is 25%. But a 10% fall causes a ₹10,000 loss, also 25% of your money, plus interest on the loan. Leverage works in both directions.
How it works in India
For holding positions beyond a day, brokers offer a Margin Trading Facility (MTF), regulated by SEBI. Only approved, generally liquid shares are eligible. You pay the required margin, the broker funds the rest, and the purchased shares are pledged to the broker as collateral. Interest is charged daily on the borrowed amount, so the cost rises the longer you hold.
SEBI has also tightened rules on leverage for intraday trading, requiring brokers to collect specified margins upfront, which has reduced the very high leverage that was once common.
Margin calls
If the value of your shares falls, your margin, your own money in the position, shrinks. When it falls below the required level, the broker issues a margin call, asking you to add money or securities quickly. If you cannot, the broker can sell your shares, often at a bad time, to recover the loan. This forced selling can turn a temporary fall into a permanent loss.
A simple example
You use MTF to buy shares worth ₹2,00,000, paying ₹80,000 yourself. The broker lends ₹1,20,000 at an annual interest rate charged daily. The share falls 25%, so your holding is worth ₹1,50,000. After repaying the ₹1,20,000 loan, only ₹30,000 of your ₹80,000 remains: a 62.5% loss on your own money, before interest. The broker would likely have issued a margin call well before this point.
The real cost
Margin interest can add up to a meaningful amount over months. For a margin trade to make sense, the expected gain must exceed both the interest and the extra risk. Over long periods, few investors earn enough to justify the cost and the danger of forced selling.
Why it matters for investors
Margin trading can magnify gains, but it also magnifies losses, adds interest costs and creates the risk of forced selling. It is generally considered unsuitable for beginners and for long-term investing.
Margin trading versus pledging your holdings
Some investors pledge shares they already own to get margin for trading other securities. This can feel like "free" money, but the same risks apply: if markets fall, the value of the pledged shares drops and the broker may sell them. Treat any borrowing against investments with the same caution as a loan.
Common misconceptions
"Margin is free extra buying power." It is a loan with interest.
"I can wait out any fall." Margin calls may force a sale before prices recover.
"Only my margin is at risk." Losses can exceed what you put in, in extreme cases.

Summary
Margin trading means buying shares partly with money borrowed from your broker. In India, the SEBI-regulated MTF requires a margin, pledges the shares as collateral and charges daily interest. Leverage magnifies both gains and losses, margin calls can force sales at bad times, and the interest adds cost, which makes it risky, especially for beginners.
