Frequently Asked Questions
What is a margin call?
A margin call occurs when the equity in a margin account falls below the maintenance margin requirement. The broker demands the investor deposit additional funds or sell securities to bring the account back to the required level.
How is margin call price calculated?
Margin Call Price = Loan Amount / (Shares x (1 - Maintenance Margin %)). This is the price at which your equity ratio drops to exactly the maintenance margin level.
What is the typical maintenance margin?
The standard maintenance margin is 25% set by FINRA regulations, though brokers may require higher margins (30-40%) for volatile stocks or concentrated positions.
