An accurate and stable numerical method for option hedge parameters

作者:

Highlights:

• The Feynman-Kac formula reduces truncation error in time direction.

• Piecewise quadratic approximation gives the third-order convergence in asset direction.

• Unconditional stability is achieved by analytic integration over the lognormal distribution.

• Local volatility surface and interest rate term structure can be used as input data.

• We use vectorized code to reduce time complexity compared to the Crank-Nicolson.
