To use these models, traders input information such as the stock price, strike price, time to expiration, interest rate and volatility to calculate an option’s theoretical price. To find implied ...
Net volatility refers to the volatility implied by the price of an option spread trade involving two or more options. Essentially, it is the volatility at which the theoretical value of the spread trade matches the price quoted in the market, or, in other words, the implied volatility of the spread.
The intrinsic value is the difference between the underlying spot price and the strike price, to the extent that this is in favor of the option holder. For a call option, the option is in-the-money if the underlying spot price is higher than the strike price; then the intrinsic value is the underlying price minus the strike price.
All other things being equal, an option's theoretical value is a monotonic increasing function of implied volatility. By computing the implied volatility for traded options with different strikes and maturities, the Black–Scholes model can be tested.
However, in general, the value of an option depends on an estimate of the future realized price volatility, σ, of the underlying. Or, mathematically: = (,) where C is the theoretical value of an option, and f is a pricing model that depends on σ, along with other inputs.
Time value is, as above, the difference between option value and intrinsic value, i.e. Time Value = Option Value − Intrinsic Value. More specifically, TV reflects the probability that the option will gain in IV — become (more) profitable to exercise before it expires. [6] An important factor is the underlying instrument's volatility ...
In finance, the binomial options pricing model (BOPM) provides a generalizable numerical method for the valuation of options.Essentially, the model uses a "discrete-time" (lattice based) model of the varying price over time of the underlying financial instrument, addressing cases where the closed-form Black–Scholes formula is wanting, which in general does not exist for the BOPM [1].
The options trader makes a profit of $200, or the $400 option value (100 shares * 1 contract * $4 value at expiration) minus the $200 premium paid for the call.
