bad:
my comment to Biffer was only light-hearted banter, as you probably realised .
I am not knowledgeable enough to give you good guidance on Shell , so better shut up till inspiration comes to me .
I have used the guts technique myself to safeguard a sold Av. 500p position which would have worked if the shares had stayed range-bound. But the shares changed direction and the sold calls came into play , so I closed out the whole position . Recently all my sold calls posed danger and I closed out most of them while the sold puts have all been great. It won't last and a severe correction is on the cards somewhere. So listen to Mr Only. His plays are pretty good for guarding against such market correction .
