Jessie bought a share of stock for $100. She borrowed $50 from her broker.
There is a 25 percent maintenance margin requirement established by the brokerage firm she does business with. The price of the stock falls to $80.
Will her broker put in a margin call to her, asking her to put up more funds?
If so, how much more? What if the price falls to $50? In each case, if so, how much more?
