option price v heads

One thing I've found interesting of late is the price gap between the heads and the options has opened a little, for example before the TPA was released and the heads were around the 2c mark the B's were about half the price so 1c and the A's were 1.2-1.3, at the moment the heads are around the 2c mark again and the B's are .7c-.8c and the A's are anywhere from 1.0-1.2c something I'm interested to see play out once the share price starts to climb, my thoughts are the oppies can't stray too far from their strike prices .9c and 1.5c respectively so if the heads where 3.5c I cant see the B's being worth any less than 2c and the A's any less than 2.6c as if they where to "fall behind" as such it would be better value to buy the oppies and convert than to buy the heads outright. but at the same time I wouldn't think they will close the gap like they have in the past, interesting times ahead Bring on the MPA
