I understand, my question was the importance of $6.50 stock price in relation to those Derivatives. I don’t believe there is a link, if there is, I have missed it.
Derivatives fail when a party cannot cover the loss, then the bank is liable. 0.001% doesn't come close to covering that risk.
A few months back, when we were worrying about an Italy default, that’s exactly what could have happened. Italy, for now is in better shape. Brexit / new EU elections could destabilise the EURO all over again. We will see.
