As I previously posted, I'm expecting a market correction at the best and a crash at the worst. So when/if you come up with a margin call there are two alternatives: come up with the cash to cover ... sell marginable stocks .. and third, but not least, sell cash stocks (u get full  cash value)  Unfortunately penny stocks fall into the third category.  so my advice is take a deep breath and ride it out.  We're in good shape. M money is parked here.
