Risk Margin Overview
What is risk based margining?
A risk based margin system evaluates your portfolio to set your margin requirements. The risk valuations of your positions are created using simulated market movements that anticipate possible outcomes. As a result, a more accurate margin model is created, allowing the investor to increase their leverage.
How are correlated risks offset?
Within a group of positions with the same underlying, 100% of the gain at any one valuation point is allowed to offset another positions loss at the same valuation point.
Example: An account holds a long stock position in stock ABC and a long put option contract in ABC. If a theoretical worst case scenario causes the underlying asset to drop 15%, then the loss that on the long stock position would be offset by the gain on the long put position.
What are my eligibility requirements?
Eligibility requirements vary according to the investor's personal information, region, and exchange.
