Overview

Stock Margin is a very vital concept which makes it possible for eligible investors to buy or trade stocks with money borrowed from their brokers. Even though margin trading will enable one to increase purchasing power, the levels of risks become higher because both losses and gains can get amplified. Understanding the concept of margin, the types and precautionary measures is helpful for the traders for them to have effective management of their capital. Whether a beginner or experienced trader, it is necessary for the trader to know about stock margins.

What is Stock Margin?

Stock margin is defined as the amount of money or securities that the trader must have for him to execute his trades through margin services from a broker. Instead of paying the total cost of a trade, the eligible trader can borrow money to increase his buying power.

The concept of stock margin is applied in equity and derivatives trading whereby traders can execute bigger trades within the stipulated margin requirements.

Unlike cash trading, margin trading requires the traders to borrow money; hence, it becomes important to understand both the benefits and risks associated with this process.

Some common risks include:

Margin Calls
