Futures and options pricing theory?
Option pricing is based on the unknown future outcome for the underlying asset. If we knew where the market would be at expiration, we could perfectly price every option today. No one knows where the price will be, but we can draw some conclusions using pricing models.
Option pricing theory is a probabilistic approach to assigning a value to an options contract. The primary goal of option pricing theory is to calculate the probability that an option will be exercised, or be in-the-money (ITM), at expiration.
A future is a contract to buy or sell an underlying stock or other assets at a pre-determined price on a specific date. On the other hand, options contract gives an opportunity to the investor the right but not the obligation to buy or sell the assets at a specific price on a specific date, known as the expiry date.
Definition: Black-Scholes is a pricing model used to determine the fair price or theoretical value for a call or a put option based on six variables such as volatility, type of option, underlying stock price, time, strike price, and risk-free rate.
The Black-Scholes-Merton (BSM) model is a pricing model for financial instruments. It is used for the valuation of stock options. The BSM model is used to determine the fair prices of stock options based on six variables: volatility, type, underlying stock price, strike price, time, and risk-free rate.
Options are priced using various mathematical models, with the most widely used being the Black-Scholes model. This model, and others like it, take into account key market data and/or assumptions to determine the price of an option.
The Black-Scholes model is perhaps the best-known options pricing method. The model's formula is derived by multiplying the stock price by the cumulative standard normal probability distribution function.
The Expectancy Model of futures pricing states that the futures price of an asset is basically what the spot price of the asset is expected to be in the future. This means, if the overall market sentiment leans towards a higher price for an asset in the future, the futures price of the asset will be positive.
Futures and options are the major types of stock derivatives trading in a share market. These are contracts signed by two parties for trading a stock asset at a predetermined price on a later date. Such contracts try to hedge market risks involved in stock market trading by locking in the price beforehand.
This is because futures contract holders are required to buy the underlying asset regardless of market price. So, if the asset is worth less than the cost of physically taking control of it, you'd have to pay someone to take the contract off your hands. Oil futures briefly went negative in 2020.
What is Black-Scholes simple formula?
Black and Scholes [1] use an arbitrage argument to derive a formula for option pricing. The risk-free asset has the constant return rdt. s = (r+µ) dt +σ dz. The stock pays no dividend, so this expression is the return on the stock.
So, N(d1) is the factor by which the discounted expected value of contingent receipt of the stock exceeds the current value of the stock. By putting together the values of the two components of the option payoff, we get the Black-Scholes formula: C = SN(d1) − e−rτ XN(d2).
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. and N(.) is the cumulative normal distribution function.
The Binomial Model and the Black Scholes Model are the popular methods that are used to solve the option pricing problems. Binomial Model is a simple statistical method and Black Scholes model requires a solution of a stochastic differential equation.

Consider an at-the-money call option that is one week to maturity on a stock with a local standard deviation of 35%/year. If the stock is selling for $50 and the continuously-compounded riskfree rate is 1%/year, then the Black- Scholes call option price is $0.9727852.
What are the best options trading strategies? The 3 best options trading strategies are selling covered calls, buying DITM LEAPS, and selling cash-secured puts.
The most common valuation models are Black-Scholes, binomial model, and Monte Carlo simulation. The Black-Scholes model utilizes differential equations, the binomial model uses binomial tree concept and assumption of two possible outcomes, and the Monte Carlo method uses random samples.
Monte Carlo is used for option pricing where numerous random paths for the price of an underlying asset are generated, each having an associated payoff. These payoffs are then discounted back to the present and averaged to get the option price.
Long Call & Put Options
A long call is considered to be the most basic options strategy. It's a contract that gives the owner the right to buy an underlying asset, e.g. 100 shares of a stock, by a certain expiration date, at a predetermined price (called the strike price).
What is the two option pricing model?
These two option pricing models (BSM and Binomial pricing model) are mathematical models to calculate the theoretical value of an option. They provide us with a fair value estimate of an option. This in turn helps investors to adjust their portfolios and strategies accordingly.
A Bull Call Spread is made by purchasing one call option and concurrently selling another call option with a lower cost and a higher strike price, both of which have the same expiration date. Furthermore, this is considered the best option selling strategy.
The 80% Rule is a Market Profile concept and strategy. If the market opens (or moves outside of the value area ) and then moves back into the value area for two consecutive 30-min-bars, then the 80% rule states that there is a high probability of completely filling the value area.
Futures are valued to eliminate arbitrage so that neither buyer nor seller can be certain of a riskless profit. We learned that this is achieved when: Futures price = (Spot price * (1 + r)^t) + (net cost of carry)
A futures price is determined by the cost of its underlying asset and moves in sync with it. The cost of futures will rise if the cost of its underlying increases and will fall as it falls. But it is not always equal to the value of its underlying asset.
