Quote from wafaul:
Yes,they are cash secured,but they pay no interest on the cash,I guess what I mean is the cash is restricted,that is you cannot put it into an an interest bearing instrument of any type.
So in this case the synthetic equivalent (covered call) is a better use of funds,I think.
Maybe funds are not restricted on long option positions,I very rarely go long so I am not sure.
