The margin call was not on SRSR and possibly because of the gains that SRSR has made lately, they were able to pay of the margin call more easily. Personally,if it was my margin call,I would have sold my other stocks and kept SRSR. The problem with holding only SRSR is that it is a non-marginal stock as are all pink sheet stocks. You can own $500,000 worth of SRSR and still not be able to buy on margin.
