Quote from atticus:
We are sorta attempting to talk about delta. Let's say, as a purely hypothetical exercise (recall the academic vacuum), that vola did rise to 70%. Can you approximate the 5-strike delta with shares also at 5? (Shhh, let's dream it's determinate-able).
Is this beyond your vast capabilities as a Master qu(a)nt?
I only make directional bets, as you know, atticus.
The stock would have to move many orders of magnitude greater before volatility would double, and unless you actually know what the implied volatility is after that change, it is still indeterminable, and depends on the options prices after and only after the change in volatility.
