Volatility | σ | 29.0% |
Risk-free Interest Rate | r | 7.50% |
Continuously compounded Dividend Yield | δ | 2.50% |

Black-Scholes vega will be calculated in the following steps:
Step-1:- Call Option price calculation
Step-2:- Vega Calculation
Step-1:- Call Option price calculation
The formula for Call Option price (d1) as per Black-Scholes option pricing model is
Putting value in the above formula we get the following
= $ 0.4050
So the Call Option price (d1) = $ 0.4050
Step-2:- Vega Calculation
The formula for Call option Vega as per Black-Scholes Formulas for Vega is
Putting value in the above formula we get the following
= 0.1041
So, the Black Scholes Vega of a $55 - strike European call option with 3 months until expiration is 0.1041.

Problem 1: - Using the Black/Scholes formula and put/call parity, value a European put option on the equity in Amgen, which has the following characteristics. Expiration: Current stock price of Amgen: Strike Price: Volatility of Amgen Stock price: Risk-free rate (continuously compounded): Dividends: 3 months (i.e., 60 trade days) $53.00 $50.00 26% per year 2% None If the market price of the Amgen put is actually $2.00 per share, is the above estimate of volatility higher or lower than the...
14. Note that the Black-Scholes formula gives the price of European call c given the time to expiration T, the strike price K, the stock’s spot price S0, the stock’s volatility σ, and the risk-free rate of return r : c = c(T, K, S0, σ, r). All the variables but one are “observable,” because an investor can quickly observe T, K, S0, r. The stock volatility, however, is not observable. Rather it relies on the choice of models the...
