Greekslive recently launched the Pro Risk Analytics feature, an institutional-grade tool for options portfolio management that makes positions reflect market risk more accurately under the SABR model. In the past, we used the BSM model to calculate Greeks, but there has always been an issue in the options market: implied volatility (IV) is a surface rather than a fixed value. The SABR model is specifically designed to describe the dynamics of the volatility surface, calculating the “total risk exposure of the entire options portfolio.” In our Pro Risk Analytics system, we can calculate numerous second-order exposures and complex parameters for your current positions, providing a risk profile under the SABR model that more closely mirrors real-market conditions. This is why we’ve been actively promoting SABR recently—to provide you with a true institutional-grade tool. If you’re a market maker, you’ll be able to determine exactly where today’s P&L comes from: Delta, Gamma, Vega, Theta, Skew, or other factors. We’ve already added 38 features for you to use. If you have any questions or want to share your experiences, feel free to send me a private message or tag me in a post—let’s learn together how to use SABR. Our first question: Is the profit from selling options really just Theta?(Greeks.live)
