Saturday night mid level derivatives trader interview question.
Let& #39;s compare two trades:
1) Vega-neutral equity index dispersion trade (long component names on their index weights; short index; same vega) in volatility swap format
Let& #39;s compare two trades:
1) Vega-neutral equity index dispersion trade (long component names on their index weights; short index; same vega) in volatility swap format
2) Vega-neutral equity index dispersion trade in fixed strike options; Black-Scholes delta neutral in index and all names; assume you dynamically manage it to keep vega/gamma on the index weights.
Question: which of these trades will exhibit a higher beta with respect to the direction of the underlying equity index? What factors does this depend on? Can you write down precisely a mathematical expression for the difference in the beta?
