## Various Topics or Fundamentals Covered in Two-Step Binomial Tree Assignment

The two-step binomial tree is a fundamental concept in financial mathematics and is commonly used to model the behavior of options, derivatives, and other financial instruments. It is a discrete-time model that represents the evolution of an underlying asset’s price over a fixed time period, typically divided into two steps. In this assignment, we will cover several important topics and fundamentals related to the two-step binomial tree.

Binomial Tree Structure: The binomial tree is constructed by starting with an initial price of the underlying asset and then branching out at each step into two possible future prices, representing an upward movement and a downward movement. This forms a binary tree-like structure, with each node representing a possible price of the asset at a particular point in time.

Risk-Neutral Probability: One of the key concepts in the binomial tree model is the risk-neutral probability. This is the probability assigned to the upward movement and downward movement of the asset’s price, such that the expected value of the asset’s price at each step is equal to the risk-free rate. The risk-neutral probability is used to calculate the option prices at each node of the binomial tree.

Option Pricing: The two-step binomial tree is commonly used to price options, which are financial contracts that give the holder the right, but not the obligation, to buy or sell an underlying asset at a specified price (the strike price) before a certain expiration date. The binomial tree is used to calculate the option prices at each node of the tree, starting from the final nodes (at expiration) and working backward to the initial node (at the present time).

Delta, Gamma, and Theta: The binomial tree can also be used to calculate various option Greeks, which are measures of sensitivity of the option price to changes in different parameters. Delta measures the sensitivity of the option price to changes in the underlying asset’s price, gamma measures the sensitivity of delta to changes in the underlying asset’s price, and theta measures the sensitivity of the option price to changes in time.

American vs. European Options: The binomial tree can be used to price both American and European options. American options can be exercised at any time before expiration, while European options can only be exercised at expiration. The binomial tree can be used to determine the optimal exercise strategy for American options, as well as to compare the prices of American and European options.

Convergence and Accuracy: The accuracy of the binomial tree model depends on the number of steps in the tree. As the number of steps increases, the binomial tree converges to the continuous Black-Scholes model, which is a widely used option pricing model in continuous time. The assignment may cover the concept of convergence and the accuracy of the binomial tree model, as well as the trade-off between accuracy and computational complexity.

Applications: The binomial tree model has wide-ranging applications in finance, including option pricing, hedging, risk management, and portfolio optimization. The assignment may cover real-world examples of how the binomial tree model is used in practice, such as pricing options on stocks, currencies, and commodities, as well as hedging strategies using options.

In conclusion, the two-step binomial tree is a fundamental concept in financial mathematics with various applications in option pricing and risk management. Understanding the binomial tree structure, risk-neutral probability, option pricing, option Greeks, American vs. European options, convergence and accuracy, and real-world applications is essential to mastering this topic. A thorough understanding of these fundamentals will provide a solid foundation for further exploration of more complex topics in financial mathematics and quantitative finance.

## Explanation of Two-Step Binomial Tree Assignment with the help of Unilever by showing all formulas

The Two-Step Binomial Tree is a mathematical model used to estimate the value of options or other financial derivatives over time, assuming discrete time steps. It is commonly used in option pricing theory and involves calculating the probabilities of different possible outcomes at each time step, and then discounting those outcomes back to the present value to estimate the option’s current value.

Let’s consider an example using Unilever, a multinational consumer goods company, to illustrate the Two-Step Binomial Tree method. Suppose we have an option to buy Unilever stock at \$150 per share, with a maturity of 2 time steps (e.g., months) and a risk-free interest rate of 5% per time step. The current stock price of Unilever is \$145, and we assume that the stock price can either increase by 10% or decrease by 5% at each time step.

Step 1: Building the Binomial Tree

We start by building a binomial tree representing the possible stock price movements over the 2 time steps. At time step 0, the stock price is \$145, and at time step 1, it can either go up to \$159.50 (10% increase) or down to \$137.75 (5% decrease). At time step 2, the stock price can either go up to \$175.45 (10% increase from \$159.50) or down to \$144.64 (5% decrease from \$137.75).

Step 2: Calculating Probabilities

Next, we calculate the probabilities of each possible outcome at each time step. Since the stock price can either go up or down at each time step, there are two possible outcomes at each node of the binomial tree. We can use the risk-neutral probability formula to calculate the probabilities, assuming that the expected return on the stock is equal to the risk-free interest rate.

At time step 1, the up probability (denoted as p) can be calculated as:

p = (e^(r * delta t) – d) / (u – d)

Where:

r = risk-free interest rate per time step (0.05 in our example)

delta t = time step (1 in our example)

u = factor by which the stock price goes up (1 + 0.10 = 1.10 in our example)

d = factor by which the stock price goes down (1 – 0.05 = 0.95 in our example)

Plugging in the values, we get:

p = (e^(0.05 * 1) – 0.95) / (1.10 – 0.95)

p = 0.555

The down probability (denoted as 1 – p) is then:

1 – p = 1 – 0.555 = 0.445

Similarly, we can calculate the probabilities at time step 2 using the same formula.

Step 3: Calculating Option Values

With the probabilities calculated, we can now estimate the option values at each node of the binomial tree by discounting the possible outcomes back to the present value. At the final time step (time step 2), the option value is simply the maximum of either the stock price minus the strike price (\$150 – stock price) or zero, depending on whether the option is in-the-money or out-of-the-money.

At time step 1, the option value at the up node is:

Max(159.50 – 150, 0) = 9.50

And at the down node:

Max(137.75 – 150, 0) = 0

We can now discount these option values back to the present value using the risk-free interest rate of 5% per time step. The present value (PV) of an option value at time step 1 is given by:

PV = Option Value / (1 + r)^t

Where:

r = risk-free interest rate per time step (0.05 in our example)

t = number of time steps from the present (1 in our example)

Plugging in the values, we get:

PV at up node = 9.50 / (1 + 0.05)^1 = 9.50 / 1.05 = 9.05

PV at down node = 0 / (1 + 0.05)^1 = 0

We repeat the same process for time step 0, discounting the PV at each node back to the present value. The option value at the present node (time step 0) is then the expected value of the discounted PVs at the up and down nodes, weighted by their respective probabilities.

Expected Option Value at time step 0 = (PV at up node * p) + (PV at down node * (1 – p))

Plugging in the values, we get:

Expected Option Value at time step 0 = (9.05 * 0.555) + (0 * 0.445) = 5.03

So, the estimated value of the option to buy Unilever stock at \$150 per share, using the Two-Step Binomial Tree method, is \$5.03 at time step 0. This represents the estimated present value of the potential future payoffs from exercising the option.

It’s important to note that the Two-Step Binomial Tree is a simplified model and may not always accurately reflect the actual market prices or behavior of financial assets. It’s just one of many methods used in option pricing theory, and there are more complex models, such as Black-Scholes-Merton, that are commonly used in practice. However, the Two-Step Binomial Tree can provide a basic understanding of how options can be priced and can be a useful tool in certain situations.

In conclusion, the Two-Step Binomial Tree is a discrete-time model used to estimate the value of options or other financial derivatives. It involves building a binomial tree to represent possible price movements, calculating probabilities of different outcomes, discounting future payoffs back to the present value, and estimating the option value. Using Unilever as an example, we illustrated the step-by-step process of the Two-Step Binomial Tree method, including all the formulas involved.
