mafipy.replication.make_pdf_fprime_black_scholes(underlying, rate, maturity, vol)[source]

make_pdf_fprime_black_scholes_model return first derivative of p.d.f. of black scholes. See make_pdf_black_scholes().

\[\Phi_{S}^{\prime}(k) := \frac{\partial}{\partial K^{2}} c(0, S; T, K)\]

where \(S\) is underlying, \(T\) is maturity, \(K\) is strike, \(\Phi_{S}(k)\) is p.d.f. of \(S\), \(c(0, S; T, K)\) is value of call option with strike \(K\) and \(T\) maturity at time 0.

Parameters:
  • underlying (float) –
  • rate (float) –
  • maturity (float) – non-negative.
  • vol (float) – volatility. non-negative.
Returns:

first derivative of p.d.f. of call price under black scholes model as a function of strike.

Return type:
