for clarity or added confusion depending on how you look at it...
Margin calls are a product of a somewhat complicated formula that is based on Initial Margin and Maintenance Margin that varies from investor to investor based on thier agreements with thier brokers.
The 25-40% range would contain most margin call triggers but may not contain all
hope I haven't caused extra confusion. If anyone feels I have poorly explained margin calls...please clarify for the benefit of the board.
Thanks
