The format used on this page calculates theta as change in option price if time to expiration decreases by one day. Therefore, negative theta means the option will lose value as time passes, which is the case with most though not all options.

The format used on this page appears to be the more popular one, although the other is still quite common. Vega is the first derivative of option price with respect to volatility σ. Note: Divide by to get the resulting vega as option price change for one percentage point change in volatility if you don't, it is for percentage points change in volatility; same logic applies to rho below. Rho is the first derivative of option price with respect to interest rate r.

It is different for calls and puts. Call options are generally more valuable when interest rates are high because a call option can be considered an alternative to owning the underlying, or a way of funding. Conversely, put options are generally more valuable when interest rates are low.

That said, if the underlying pays dividends, it is mainly the interest rate net of dividend yield r — q rather than interest rate itself r that drives option prices. All these formulas for option prices and Greeks are relatively easy to implement in Excel the most advanced functions you will need are NORM.

DIST, EXP and LN. You can continue to the Black-Scholes Excel Tutorial , where I have demonstrated the Excel calculations step-by-step first part is for option prices, second part for Greeks.

Write the appropriate boundary conditions. the payoff. is correct, but you should derive it using appropriate logic, not just guessing the answer. Ie the drift of discounted stock should be 0.

This can help you find the correct mu. In this case the pde is the same as the black scholes pde using your risk neutral process. Can you think of why this is? Does the type of call option change how the underlying changes? Take a look at dirichlet also known as zero gamma condition and other types of boundary conditions.

That is the right start, but what is the expectation? Plug this into your formula. The problem is that this expectation is in real probability space and you want it in your risk neutral space.

This is the standard normal probability density function: Delta Delta is the first derivative of option price with respect to underlying price S. In this case, closed-form solutions are available if the dividend is a known proportion of the stock price.
