It depends on what you want to achieve. If you arb skew, then of course you would want to hedge with the option on the other side of spot (you sold a otm call so you want to buy an OTM put) and hedge delta with shares.Thanks Mr, I also appreciate your clear contribution. It's getting me to think. I will the read Passarelli book.
I have a question on maintaining neutrality in practice.
If I sell premium and want to stay as neutral as possible, what would be a valid method of adjustment? An X deviation of delta or gamma to be adjusted with shares or option depending on what's needed, or a time (daily, weekly, monthly) adjustment toward neutral? Or both?
OTM vs ATM you oviously also want to hedge with options.
IV vs. stat vol you buy nuke protection and use shares.
When it comes to risk, you want to establish min/max for each greek and try to stay within that greek regardless of time.
