Volatility of volatility is not new in town
•
Every option book has exposure to vol of vol (i.e. gamma of gamma or 4th moment)
•
Vol of vol is the sensitivity of out-of-money options in relation to those at-the-money
•
Why we increasingly hear about it: •
Because vol of vol is directly related to “convexity”
•
Because vol of vol is directly related to “tails” (post-crisis everyone cares about “tails”)
•
Because VIX options are now being used by a wide range of market participants, and vol of vol matters in pricing and trading them 3
How to get exposure to vol of vol (pre-VIX options or other underlyings) Ratio back spreads: trade ATM options vs. multiple OTM options •
Sell 1 ATM call Buy 2 x OTM call delta hedged
•
Not as “clean” as trading vol of vol products (lower moments can take over)

Vol of vol in practice: Similarities to commodities and fixed income •
Each maturity represents a different underlying •
•
•
VIX futures are “forwards”: curve dynamics similar to forward rates
VIX and commodities exhibit higher uncertainty in the shorter maturities •
For commodities, the reason is supply/demand disruptions and implication of storage
•
VIX is similar: supply demand of gamma (the shorter expiry S&P option prices are – all else being equal – more sensitive to market movements, hence buying or selling gamma)
While the curves of the underlyings have many degrees of freedom, they are held by various relationships •
Fixed income: bootstrapping
•
Commodity: cost of carry 14

Vol of vol in practice: Similarities to commodities and fixed income What kind of practical implications? •
If one has fundamental views on the underlying:
•
Calendar spread trades
•
Conditional curve trades
•
Roll down (carry) trades
•
Options on spread (i.e curve options in fixed income or CSO)
•
Midcurve options (ex: an option on June VIX expiring in April)

Vol of vol in practice: Examples of carry and hedge
Volatility (%)
Roll down (carry trade)
Buy a short dated put
Sell a long dated put
•
Put calendars
•
Starts by having a view on the VIX term structure
•
Takes into account concavity, vol of vol level to estimate positive carry
VIX future maturity

Risk-off hedge

Vol of vol and VIX options: Some practical considerations Volatility of VIX options is high enough for usual “intuition” and “common sense” to be misleading •
Delta of a month ATM call with a 120 vol and 2 month to expiry is 60%
Delta hedging (for those who want to pick up the risk premium) •
Can we (should we) use a different model than B&S? •
•
CEV, local volatility, SABR, etc.
If we use B&S to price, what approach should we have: “sticky delta” or “sticky strike”? •
Let’s look at the real option prices and see how they have behaved to get a clue

Volatility products and the vol of vol
We have witnessed tremendous evolution (increase) in VIX ETNs •
1 Month constant maturity ETN launched in 2010
•
Increase in levered ETNs AUM (and vega) since 2012
•
Addition of dynamic ETNs
•
And many OTC products offered by dealers (systematic and dynamic/rule based)
Has this proliferation of volatility products had any effect on the behavior of volatility? •
We have observed increased vol of vol in recent past

Volatility of volatility: Final thoughts •
A direct way to hedge or get exposure to “convexity”
•
The advent of volatility products has made vol of vol accessible to many participants and is efficiently tradable
•
The liquidity in the VIX complex has made many previously theoretical strategies a possibility
•
Trading instruments with vol of vol exposure requires some preparation: understand pricing and sensitives
•
More products will (hopefully) emerge and complete the market •
Mid-curves, spread options, etc.
