Investor's Equity

The balance of money or securities an investor keeps in a margin account in order to be able to borrow from a brokerage for short sales or other purposes. Investor's equity is kept as collateral until the brokerage calls the margin and the client pays back what is owed. FINRA requires that investor's equity must be at least 25% of the amount borrowed at all times, while some brokerages require equity of up to 50%. See also: Maintenance.
