Option Greeks. Dissecting Delta, Gamma, Vega, Theta & Rho
It doesn’t matter if you took the FRM, CFA, PRMIA, CERA, SOA, CAS or the FIA investment / risk management exam this November/December. There was one section in the curriculum that gave you pause, occasionally a headache, but more frequently became the leading indicator for a panic attack. As a graduate business school student, despite a full term of instructional seminars behind you, an interview or modeling question on Greeks could unseat the most sure footed Quants amongst us.
Option price sensitivities or Greeks have that impact on ordinary mortals reviewing derivative risk management sections of their text books. This weekend we declare war on Greeks with the full force and might of our Excel spreadsheet and a handy online instructional guide. If you have had enough of being cowed by delta, gamma, vega, theta and rho, pick up your Spartan shield and spear, charge your laptop, load Excel and follow us on what promises to be an exciting and interesting ride.
For best results, follow the session and try and build your own Excel spreadsheet using the information and sequence provided below. If you get lost or confused, drop us a note. Use the weekend wisely to finally overcome your fear of modeling option Greeks.
War on Option Greeks – Introduction – Preliminary skirmishes
Our game plan is simple. Build an Excel model and get the formula out of the way. Extend the model to simulate delta hedging and cash PnL. Use the model to build intuition.
The first phase of our war requires us to get comfortable with our primary weapons. An Excel spreadsheet that plots Greek behavior across multiple dimensions and a Monte Carlo Simulation that simulates hedge performance and accuracy. Go forth and build.
One word of warning. We assume that you are comfortable with derivative pricing & Monte Carlo Simulation. If that is not true, please see the Option pricing 5 night free crash course.

You have a great website, and looks of it, a cool training program. I wish I could understand all these Acturial terms.
Best wishes Jawad.
