As above, the PDE is expressed in a discretized form, using finite differences, and the evolution in the option price is then modelled using a lattice with corresponding dimensions: time runs from 0 to maturity; and price runs from 0 to a "high" value, such that the option is deeply in or out of the money. The option is then valued as follows: [5]
Here the price of the option is its discounted expected value; see risk neutrality and rational pricing. The technique applied then, is (1) to generate a large number of possible, but random, price paths for the underlying (or underlyings) via simulation, and (2) to then calculate the associated exercise value (i.e. "payoff") of the option for ...
The following calculation assumes the sold call option and the purchased put option are both out-of-the-money and the price of the stock at expiration is the same as at entry: %If Unchanged Potential Return = (call option price - put option price) / [stock price - (call option price - put option price)]
Futures vs. options: Key differences. Both futures and options give traders the power of leverage, allowing them to put up a little money to profit on the move of a much larger quantity of the ...

Forward prices of equity indices are calculated by computing the cost of carry of holding a long position in the constituent parts of the index. This will typically be the risk-free interest rate, since the cost of investing in the equity market is the loss of interest minus the estimated dividend yield on the index, since an equity investor receives the sum of the dividends on the component ...
The Black formula is similar to the Black–Scholes formula for valuing stock options except that the spot price of the underlying is replaced by a discounted futures price F. Suppose there is constant risk-free interest rate r and the futures price F(t) of a particular underlying is log-normal with constant volatility σ.
Options trades generally take place while the markets are open, with only a few exceptions extending after hours. However, those trades only allow you to trade until 4:15 p.m. in most cases.
