What are the benefits?
Because you are making a bigger investment, if your shares increase in value, you will realise higher profits. There are also tax incentives associated with using a margin lending loan to fund your investments.
Conversely, a drop in your share values will potentially see you making larger losses.
If this occurs to the point where the value of your investment falls below the amount you borrowed, you will experience negative equity, and may need to repay more money than you borrowed. Share market investments are also generally risky because of the uncertainty of price movements.
