Introduction to the Black-Scholes formula (BSM)

Показать описание
Black-Scholes option pricing model (its Merton’s extension that accounts for dividends), there are six parameters which affect option prices:

So = underlying price ($$$ per share)
X = strike price ($$$ per share)
σ = volatility (% p.a.)
r = continuously compounded risk-free interest rate (% p.a.)
q = continuously compounded dividend yield (% p.a.)
t = time to expiration (% of year)

Value of call option = So * ND1 - K *e^-rt * ND2
Value of put option = K * e^-rt* ND2 - So* ND1

Calculation of ND1 & ND2 in case of call option

D1 = [ ln(So/K) + (r + ∂ ^ 2 / 2) * t ] / [ ∂ * sqrt (t) ]
D2 = [ ln(So/K) + (r - ∂ ^ 2 / 2) * t ] / [ ∂ * sqrt (t) ]

Normal Distribution formal in spreadsheet = normsdist(d1), normsdist(d2)

For put option use "-" in normsdist(-d1) or normsdist(-d2)

Thank you for taking this topic for clear understanding. i would like to make certain correction . The formula for ND1 is in fact formula for D1. D2 IS D1- SD * SQRT(TIME). ND1 AND ND2 can be calculated with NORMSDIST() FUNCTION OF EXCEL.
