&lt;br /&gt;
J&#39;ai repris l&#39;article de Global Hedge qui s&#39;intitutle &quot;On Delta Symmetry, Gamma-Vega Parity : Ultimate Symmetry&quot; écrit par &lt;a href=&quot;http://www.global-hedge.fr/presentation.php&quot; target=&quot;_blank&quot;&gt;Morgane TRAMASAYGUES&lt;/a&gt; .&lt;br /&gt;
Voici l&#39;article, en anglais dans le texte :&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
After « Call Put Parity », « Call Put Symmetry », « SuperSymmetry »....now..... « Ultimate Symmetry ».&lt;br /&gt;
Here we are !&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Ultimate Symmetry is a particular relationship for options with the same maturity that is really interesting from a trader’s point of view. Despite being derived in a world where&amp;nbsp; implied volatility remains the same for every strike on a given expiry, it helps traders to find options that would naturally match their greeks in the real world.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;u&gt;&lt;i&gt;&lt;b&gt;I - A « Flat Vol’ » World&lt;/b&gt;&lt;/i&gt;&lt;/u&gt;&lt;br /&gt;
&lt;br /&gt;
Assume that all strikes for a maturity T have the same implied volatility – a « Flat Vol’ World » ( It doesn’t mean that every maturity needs to have the same implied volatility, but every strike for each maturity has the same one).&lt;br /&gt;
&lt;br /&gt;
If one set for that maturity T the Delta Neutral Straddle Strike as&lt;br /&gt;
&lt;br /&gt;
K&lt;sub&gt;Delta Neutral Straddle&lt;/sub&gt; = S . exp(( r - q + 0.5.σ²).T)&lt;br /&gt;
&lt;br /&gt;
Where&lt;br /&gt;
S underlying spot&lt;br /&gt;
K strike price&lt;br /&gt;
r continuously compounded interest rate&lt;br /&gt;
q continuously compounded dividend rate&lt;br /&gt;
T expiry (in year(s))&lt;br /&gt;
σ implied volatility&lt;br /&gt;
&lt;br /&gt;
(Which is the strike where Call and Put have deltas that exhibit the same absolute value, it’s also the strike where vega is maximum and then volga is nil (∂Vega /∂σ = 0 )).&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Then, &lt;br /&gt;
&lt;br /&gt;
For every Call struck at KCall with the same maturity T it exists a Put struck at KPut with maturity T that matches simultaneously the absolute values of delta, gamma and vega, and,&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
K&lt;sub&gt;Put&lt;/sub&gt; = (K&lt;sub&gt;Delta Neutral Straddle&lt;/sub&gt; )² / K&lt;sub&gt;Call&lt;/sub&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
For that Strike We have,&lt;br /&gt;
&lt;br /&gt;
Delta Symmetry :&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; Δ Put = - Δ Call&lt;br /&gt;
The delta of a Call struck at K has the opposite value as the delta of a Put struck at (K&lt;sub&gt;Delta Neutral Straddle&lt;/sub&gt;)²/K .&lt;br /&gt;
ΔC( S, K, r, q, σ, T ) = - ΔP( S, ( K&lt;sub&gt;Delta Neutral Straddle&lt;/sub&gt;)²/K, r, q, σ, T )&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Gamma Parity :&amp;nbsp; Γ Put = Γ Call&lt;br /&gt;
The gamma of a Call struck at K has the same value as the gamma of a Put struck at (K&lt;sub&gt;Delta Neutral Straddle&lt;/sub&gt;)²/K .&lt;br /&gt;
Γ C( S, K, r, q, σ, T ) = Γ P( S, ( K&lt;sub&gt;Delta Neutral Straddle&lt;/sub&gt;)²/K, r, q, σ, T )&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Vega Parity : νega Put = vega Call&lt;br /&gt;
The vega of a Call struck at K has the same value as the vega of a Put struck at (K&lt;sub&gt;Delta Neutral Straddle&lt;/sub&gt;)²/K .&lt;br /&gt;
Vega C( S, K, r, q, σ, T ) = Vega P( S, ( K&lt;sub&gt;Delta Neutral Straddle&lt;/sub&gt;)²/K, r, q, σ, T )&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
In a Black-Scholes world, if you’ve found for a given asset which is worth XXX USD,&amp;nbsp; K&lt;sub&gt;Delta Neutral Straddle&lt;/sub&gt; = 110 for a given maturity T,&lt;br /&gt;
→ You already know how to hedge the delta of a long position of 500 Calls struck at 179 with the same maturity by buying 500 Puts struck at KPut = (110)² / 179 = 67.59&lt;br /&gt;
The 67.59 Put and de 179 Call with the same maturity will have opposite deltas, the same gamma and the same vega.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;u&gt;Risk Reversal.&lt;/u&gt;&lt;br /&gt;
As far as you know that KDelta Neutral Straddle = 110 , you know how to build a Risk Reversal that is gamma neutral and vega neutral using for example a long 120 Call with the same maturity T, by selling a Put struck at KPut= (110)² / 120 = 100.83 with maturity T. &lt;br /&gt;
&lt;br /&gt;
&lt;u&gt;Vega Weighted Butterfly&lt;/u&gt;&lt;br /&gt;
If K&lt;sub&gt;Delta Neutral Straddle&lt;/sub&gt; = 110 , you know how to build a Vega Weighted Butterfly using the 120 call with the same maturity T, and the Put struck at&amp;nbsp; (110²)/120 = 100.83 with maturity T by selling 1 Straddle struck at K&lt;sub&gt;Delta Neutral Straddle&lt;/sub&gt; = 110 and buying (Vega Call &lt;sub&gt;Delta Neutral Straddle&lt;/sub&gt; / Vega Call 120 ) . Strangle (120 Call + 100.83 Put )&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;u&gt;&lt;i&gt;&lt;b&gt;II - A Real World&lt;/b&gt;&lt;/i&gt;&lt;/u&gt;&lt;br /&gt;
&lt;br /&gt;
In a flat vol’world, that would match (-)delta, gamma and vega. You won’t even have to care about ΔCall&amp;nbsp; ΓCall and νega Call values, you already know that they will naturally match. There would be no need to price them.&lt;br /&gt;
&lt;br /&gt;
Our world is not a flat BS Implied Volatility World, that’s a fact, but the relationship remains valid as an approximation. It provides a simple way to approximate the real solution. It may even provide tools to price for a given delta how far from the BS strike the market strike is, as a pricing tool for the skew. It provides also a different way to replicate knock out / knock in options using a risk reversal.&lt;br /&gt;

For&amp;nbsp; KPut = (KDelta Neutral Straddle )² / KCall&lt;br /&gt;

&lt;br /&gt;

d1= (ln(S/KPut) + (r-q + 0.5. σ²)T) / σ√T = (ln(S. KCall /( S . exp(( r-q + 0.5.σ²).T)²) + (r-q + 0.5. σ²)T) / σ√T&lt;br /&gt;
d1= (ln(S/KPut) + (r-q + 0.5. σ²)T) / σ√T = (ln(KCall /(S.(exp(( r-q + 0.5.σ²).T)²) + (r-q + 0.5. σ²)T) / σ√T&lt;br /&gt;
d1= (ln(S/KPut) + (r-q + 0.5. σ²)T) / σ√T = (ln(KCall /(S) -ln(exp(( r-q + 0.5.σ²).T)²) + (r-q + 0.5. σ²)T) / σ√T&lt;br /&gt;
d1= (ln(S/KPut) + (r-q + 0.5. σ²)T) / σ√T = (ln(KCall /(S) -2ln(exp(( r-q + 0.5.σ²).T)) + (r-q + 0.5. σ²)T) / σ√T&lt;br /&gt;
d1= (ln(S/KPut) + (r-q + 0.5. σ²)T) / σ√T = (ln(KCall /(S) -2( r-q + 0.5.σ²).T + (r-q + 0.5. σ²)T) / σ√T&lt;br /&gt;
d1= (ln(S/KPut) + (r-q + 0.5. σ²)T) / σ√T = (ln(KCall /(S) -( r-q + 0.5.σ²).T) / σ√T&lt;br /&gt;
&lt;br /&gt;
d1Put= (ln(S/KPut) + (r-q + 0.5. σ²)T) / σ√T = - (ln(S / KCall) +( r-q + 0.5.σ²).T / σ√T) = -d1Call&lt;br /&gt;
d1Put= -d1Call&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; hence&amp;nbsp;&amp;nbsp; -d1Put=&amp;nbsp; d1Call&lt;br /&gt;
&lt;br /&gt;
N(-d1Put) =N (d1Call )&lt;br /&gt;
Exp(- qT).N(-d1Put) = Exp(- qT).N (d1Call )&lt;br /&gt;
&lt;br /&gt;
Then,&amp;nbsp; &lt;b&gt;-Δ Put =&amp;nbsp; Δ Call&lt;/b&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;i&gt;&lt;b&gt;Gamma Parity &lt;/b&gt;&lt;/i&gt;:&amp;nbsp; Γ Put = Γ Call&lt;br /&gt;
&lt;br /&gt;
If&amp;nbsp;d1Put= -d1Call&lt;br /&gt;
&lt;br /&gt;
Then,&lt;br /&gt;
&lt;br /&gt;
Since n(x) = 1/(√2π)exp(-x²) is an even function&lt;br /&gt;
n(-d1Put) = n (d1Call )&lt;br /&gt;
Exp(- qT). n(-d1Put) / ( S σ√T ) = Exp(- qT). n (d1Call )&amp;nbsp; / ( S σ√T )&lt;br /&gt;
&lt;br /&gt;
And&amp;nbsp;&lt;b&gt; Γ Put = Γ Call&lt;/b&gt;&lt;br /&gt;

&lt;br /&gt;
&lt;i&gt;&lt;b&gt;Vega Parity&lt;/b&gt;&lt;/i&gt; : νega Put = vega Call&lt;br /&gt;
&lt;br /&gt;
Since vega = Γ . σ . S² . T&lt;br /&gt;
&lt;br /&gt;
&amp;nbsp;if Γ Put = Γ Call&lt;br /&gt;
&lt;br /&gt;
&amp;nbsp;Then, (σ . S² . T). Γ Put = (σ . S² . T). Γ Call&lt;br /&gt;
&lt;br /&gt;
&amp;nbsp;And ,&amp;nbsp; &lt;b&gt;νega Put&amp;nbsp;&amp;nbsp; =&amp;nbsp; vega Call&lt;/b&gt;&lt;br /&gt;

&lt;br /&gt;
Petit Quizz de décrassage de cerveau :&amp;nbsp; Question Delta Symmetry - si on imagine qu&#39;on est dans un monde version Black &amp;amp; Scholes, comment connaissant le strike d&#39;une option je peux trouver immédiatement le strike d&#39;une autre qui matche le delta ? Posée différemment, si on vous donne le prix d&#39;un call strike X, comment vous faites pour trouver le strike du put Y tel que le portefeuille call X + put Y est delta neutre ?&lt;br /&gt;

D&#39;un autre côté, on a le marché. Et lui, les commentaires, il les aime bien mais il s&#39;en fout.&lt;br /&gt;
Alors quand on regarde un peu ce qu&#39;il valorise ce marché, voilà ce qu&#39;on a avec un future DEC 12 à 2655 :&lt;br /&gt;

En un mois ( 20 Nov - 20 Dec ) (=&amp;gt; le dernier post &lt;a href=&quot;http://les-options.blogspot.fr/2012_11_01_archive.html&quot; target=&quot;_blank&quot;&gt;ici&lt;/a&gt; ) la volatilité ATMF a baissé de 4%, faut attendre mars et juin pour avoir une baisse de 3% et 2%.&lt;br /&gt;
Le calme est là, c&#39;est clair. Donc si fin du monde et/ou fin de la zone Euro etc... et bien on le prend plutôt bien !&lt;br /&gt;

&lt;br /&gt;
En reprenant les volatilité par strike (prix d&#39;exercice) et par maturité cela donne pour les échéances jusqu&#39;à Juin 2013 : &lt;br /&gt;
&lt;br /&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;

&lt;br /&gt;
On remarque bien les volatilités qui sont croissantes pour un strike donné en fonction de la maturité. Plus la maturité augmente, plus la volatilité implicite augmente.&lt;br /&gt;
Ce type de représentation est intéressant une fois qu&#39;on connait les caractéristiques de chaque strike, mais pas avant. C&#39;est pour cette raison que je les représentais en fonction de la moneyness et pas en fonction du strike. Les contrats futures sur lesquels sont &quot;écrites&quot; les options ne sont pas les mêmes pour toutes les maturités.&lt;br /&gt;
&lt;br /&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh_rPxPUCQrqN7_nJmu4ppZnr9505GUjG-iyo2Cs1rf8zdd4QkykXQjRJGyG6V57eueUND9b9P6RhJ8gZOQBzwiu9au3YT0bCnV_hJQEt7MwQigtXbL0y9aRuTQR1E4d2Ssa13g3SWp5T5B/s1600/DJEuroStoxx50-ATMF-Implied-Volatility-20121104.jpg&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;156&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh_rPxPUCQrqN7_nJmu4ppZnr9505GUjG-iyo2Cs1rf8zdd4QkykXQjRJGyG6V57eueUND9b9P6RhJ8gZOQBzwiu9au3YT0bCnV_hJQEt7MwQigtXbL0y9aRuTQR1E4d2Ssa13g3SWp5T5B/s640/DJEuroStoxx50-ATMF-Implied-Volatility-20121104.jpg&quot; width=&quot;640&quot; /&gt;&lt;/a&gt;&lt;/div&gt;
Si on recalcule comme au dessus la volatilité implicite ATMF (Strike = Forward), et le strike par maturité tel que le delta soit 50%, on voit bien qu&#39;il peut y avoir des différences très importantes en fonction de l&#39;échéance choisie. Entre Dec 12 et Jun 13, 50 points environ soit 2%.&lt;br /&gt;

Après les vagues de baisse et les mises en garde sur les perspectives de la zone euro (et des entreprises de la zone euro), le calme transpire des volatilités des options sur l&#39;indice européen de référence.&lt;br /&gt;

Si on enlève l&#39;échéance la plus courte, on voit que sur Aout c&#39;est la plage et les cocotiers.&lt;br /&gt;
Septembre ouvre un œil et c&#39;est Décembre qui revient sur des niveaux de volatilité qui correspondent plus à ce que l&#39;on a rencontré sur le premier semestre 2012.&lt;br /&gt;

Fait plutôt sympa avec les options et qui ne peut pas être observé par les variations de l&#39;indice lui même, c&#39;est que la &lt;a href=&quot;https://sites.google.com/site/lexiquefinance/home/v&quot; target=&quot;_blank&quot;&gt;volatilité implicite&lt;/a&gt; des options ne s&#39;est pas effondrée, elle.&lt;br /&gt;

On n&#39;a pas été surpris.&lt;br /&gt;
En regardant les volatilité avec une matrice, par échéance et par &quot;moneyness&quot; on peut avoir une vue bien plus précise sur la manière dont les sentiments de marché se retranscrivent au travers des cours des options.&lt;br /&gt;
Les marchés étant tous corrélés, les sentiments (euphorie, peur, ....) exprimés dans les prix des options et représentés en volatilités implicites conditionnent forcément les marchés des sous-jacents, ne serait ce qu&#39;à cause de leurs couvertures.&lt;br /&gt;

&lt;br /&gt;
La volatilité implicite exprimée par spot / strike (moneyness) montre une certaine linéarité sur les échéances longues, et devient plus abrupte au fur et à mesure que l&#39;échéance diminue.&lt;br /&gt;
&lt;br /&gt;
Les niveaux relatifs des volatilités implicites entre échéances montrent une certaine anticipation que font les opérateurs sur les mouvements de l&#39;Eurostoxx 50 au cours de l&#39;année.&lt;br /&gt;
&lt;br /&gt;
Les mouvements sont venus du court terme, avec une volatilité &lt;a href=&quot;http://www.strategies-options.com/fic/164-at-the-money-forward-relationships-1.html&quot; target=&quot;_blank&quot;&gt;ATMF&lt;/a&gt; sur l&#39;échéance Avril qui passe de &lt;a href=&quot;http://les-options.blogspot.fr/2012/04/une-volatilite-implicite-qui-reste.html&quot; target=&quot;_blank&quot;&gt;19%&lt;/a&gt; à 25%. Sur décembre, le mouvement est plus léger, avec une hausse de &lt;a href=&quot;http://les-options.blogspot.fr/2012/04/une-volatilite-implicite-qui-reste.html&quot; target=&quot;_blank&quot;&gt;23.21%&lt;/a&gt; à 24.94%.&lt;br /&gt;

On reste très calme sur le prix des options, personne ne s&#39;emporte.&lt;br /&gt;
Avec ces prix, on est à un peu plus de 7% de spread en points de &lt;a href=&quot;http://www.strategies-options.com/fic/326-volatilite-implicite.html&quot; target=&quot;_blank&quot;&gt;volatilité implicite&lt;/a&gt; sur le risk reversal -10% / +10% sur DEC12.
