Implied volatility newton raphson

WitrynaThe most widely used technique for the estimation of the implied volatility is the Newton-Raphson iterative algorithm. It involves making an initial guess as to the implied volatility of the option. It then uses the Greek derivative of the option price relative to changes in volatility (the vega) to make a new guess if the initial guess is … Witryna18 lut 2013 · Analysts compare implied and historical volatility to judge whether the option is fairly priced. Quantitative analysts use several numerical methods to calculate implied volatility, including Newton-Raphson iteration and numerical bisection. The latter is easy to implement, and, unlike the Newton-Raphson approach, does not …
