What the margin means

The limit to the amount you can borrow on your margin loan is set by the value of your securities. As the market fluctuates, the value of your securities may go up or down. This in turn changes the upper limit to the amount you can borrow. Because of this, the margin between your balance and your loan limit can be a powerful tool as there is no set loan limit.

How a loan margin rises or falls
This fictional example shows how a loan margin changes with an increase or decrease of 10% in the value of the portfolio. Chris's initial investment is a diverse share portfolio with a total market value of $40,000. For the purpose of the example, the loan limit for each share investment is set to an average of 75%. Chris borrowed half the value of the investment, $20,000, so the loan is geared to 50%. He has $10,000 in available funds.

In Scenario 2 when the investment value of Chris's portfolio drops, he has $7,000 in available funds.

In Scenario 1 when the investment value of Chris's portfolio rises, he has $13,000 in available funds. In this scenario, Chris can borrow more using the multiplier effect.
