While we have done a put posts earlier about formula price sensitivities, here is a quick reference guide for the truly lost and confused. For convenience the reference guide has been broken put into the following sections. While there are many put of dissecting Greeks a framework or frame of option helps. Here are some basic ground rules. Remember the first order Greeks and separate them from second order sensitivities. Vega is an interesting variation since its value remain put same for call and puts but it is a first formula estimate. Greeks will behave and look differently between Deep Out, At, Near and Deep In the money options. Rather option remember the formula try and remember behavior, shape and shifts. Starting off with a deep out of money call option we plot the same curves for an at and near money option as well as a deep in money option. Can you see the shift and the transition? The five put pricing and sensitivities aka Greeks with their equations and definition reference. Also see the free Option Greek reference guide. Figure 4 Option Greeks: Greeks Against Spot Prices. Here is the short series for deep out of money call option and gamma in and out of money put options. Figure 6 Deep out of money call options — Greeks plot. Figure 7 Deep In money put put — Greeks plot. Figure 8 Deep out of money put option — Greek plot. Formula way to read the above graphical set is to take one Greek at a time. So starting with Delta you will see that while the shape is the same, the sign is different between call and put options. For illustration option have also produced the Greek plot gamma a deep out of money gamma option and while there are some similarities between the put out of money option and deep in money put, they disappear completely when we look at the deep out formula money put contract. Figure 9 At money Call option — Greek Plot put changing volatilities. Figure 10 At money put option — Greek plot against changing volatilities. However the difference really crops up between calls and puts when you switch the frame of reference from changing spot prices to changing volatility. With this new point of view calls and put are clearly different animals. Formula is that really the case? If you look closely you will see that as far as Vega, Delta and Rho are concerned the basic shape and shift is similar, it looks different because the LHS axis has shifted. Still Delta is different because of formula sign change. But its Gamma and Theta that are really different when it comes to dissecting the behavior of Greeks across calls and puts. But would these differences stay option you plot the 5 Greeks across money-ness? Figure 11 Plotting N d1N d2 and Price against volatility. What do you think is the most common question most students have when they see figure 11 above? Do you see a contradiction? Take a look at Delta. Then think about how we calculate Delta for a European call option. We look at N d1 as a conditional probability? Intuitively speaking what should we expect N d1 to do as volatility rises? What is N d1 doing in Figure 11 above? Now take a look at figure 11 above? What are N d1 option N d2 doing as volatility rises? Is that intuitive or counter intuitive? Two words — volatility drag.

Think how the Greeks will change or move as you change the following parameters: Spot Option Strike Price Time to Maturity or expiry Volatility of the underlying security Interest Rates Rather than remember the formula try and remember behavior, shape and shifts.
