Interesting that according my BS model that NCPWMN is showing the sell at around fair price. Based imp'vol of 64.9 yet NCPWGD should be around 9.5c same modeling imp'vol 57.3 but selling for nearly a cent less than fair value.
I am using Parity for imp'vol numbers and seeing as they are so far behind with turnover during trading perhaps they are also out of sorts with implied volatility, but why with one and not the other.
And yes...it is the latter that I bought.
