Adaptive Gradient Descent Methods for Computing Implied Volatility

Yixiao Lu, Yihong Wang, Tinggan Yang

摘要:

本文提出了一种基于自适应梯度下降优化算法的计算Black-Scholes(B-S)期权定价模型的隐含波动率的数值方法。结果表明,新方法比封闭形式近似更精确。与Newton-Raphson方法相比,新方法具有收敛速度快、对初始点不敏感等优点。

英文摘要:

In this paper, a new numerical method based on adaptive gradient descent optimizers is provided for computing the implied volatility from the Black-Scholes (B-S) option pricing model. It is shown that the new method is more accurate than the close form approximation. Compared with the Newton-Raphson method, the new method obtains a reliable rate of convergence and tends to be less sensitive to the beginning point.
