Describe the process of buying a stock on margin, compute the rate of return on a margin transaction, define maintenance margin, and determine the stock price at which the investor would receive a margin call.
Determine the stock price at which the investor receives a margin call by solving for the critical stock price, P, as:
[(#of shares x p) – margin loan] / (# of shares x P) = % of Maintenance Margin
