What is Financial Modelling?




Financial modelling is the process of building a forecast of an organizations future financial performance. A financial model considers the organizations past results, as well as current earnings and expenses, to predict the impact of their future decisions, the performance of particular assets and the overall financial health of the organization.


Financial models are used for various purposes, such as:



  • Valuation: To estimate the value of a business or an asset based on its expected cash flows.



  • Investment analysis: To evaluate the profitability and risk of an investment project or opportunity.



  • Budgeting and planning: To set goals and allocate resources for a business or a project.



  • Scenario analysis: To test how different assumptions or events affect the outcome of a model.



  • Decision making: To support and justify strategic or operational decisions.



Financial models can be built using different methods and techniques, depending on the purpose and complexity of the model. Some of the common methods and techniques are:



  • Discounted cash flow (DCF) analysis: To calculate the present value of future cash flows using a discount rate.



  • Sensitivity analysis: To measure how the output of a model changes with respect to changes in one or more input variables.



  • Monte Carlo simulation: To generate random scenarios based on probability distributions and statistical methods.



  • Regression analysis: To estimate the relationship between a dependent variable and one or more independent variables.



  • Machine learning: To use algorithms and data to learn from patterns and make predictions.

What are Some Examples of Financial Modelling with MATLAB?




To give you some ideas of what you can do with MATLAB for financial modelling, here are some examples of financial modelling applications that are covered in the book and in the MATLAB source.zip file. These examples are not exhaustive, but they illustrate some of the topics and techniques that you can learn and apply using MATLAB.


Pricing and Hedging Derivatives




Derivatives are financial instruments that derive their value from an underlying asset, such as a stock, a bond, a commodity, a currency, or an index. Derivatives can be used for various purposes, such as hedging, speculation, arbitrage, or portfolio diversification. Some of the common types of derivatives are options, futures, swaps, forwards, etc.


Pricing and hedging derivatives involves determining their fair value and their sensitivity to changes in market factors, such as interest rates, volatility, exchange rates, etc. Pricing and hedging derivatives can be challenging because they often depend on complex models and assumptions that may not reflect reality accurately. Therefore, it is important to use appropriate methods and tools to price and hedge derivatives correctly and efficiently.


MATLAB can help you with pricing and hedging derivatives in several ways, such as:



  • Implementing various models for pricing derivatives, such as Black-Scholes model, binomial model, trinomial model, Monte Carlo simulation model, etc.



  • Calculating various measures for hedging derivatives, such as delta, gamma, vega, theta, rho, etc.



  • Performing sensitivity analysis and scenario analysis for pricing and hedging derivatives.



  • Comparing different models and methods for pricing and hedging derivatives.



For example, in Chapter 4 of the book (and in folder 04_Basics_and_Derivatives), you can find MATLAB code that shows how to price European call and put options using different methods (analytic formula, Monte Carlo simulation , binomial tree, trinomial tree, etc.). You can also find MATLAB code that shows how to hedge European call and put options using delta hedging and gamma hedging strategies.


Portfolio Optimization and Risk Management




Portfolio optimization and risk management are two related aspects of financial modelling that deal with the selection and allocation of assets in a portfolio, and the measurement and mitigation of the risks associated with the portfolio. Portfolio optimization and risk management can help investors achieve their financial goals, such as maximizing returns, minimizing risks, diversifying exposure, or meeting constraints.


MATLAB can help you with portfolio optimization and risk management in several ways, such as:



  • Creating and managing portfolio objects using functions and classes, such as Portfolio , PortfolioCVaR , PortfolioMAD , etc.



  • Estimating the expected returns and risks of different assets and portfolios using functions and tools, such as mean , std , cov , corr , sharpe , portstats , etc.



  • Optimizing the portfolio weights using various criteria and constraints, such as mean-variance, mean-CVaR, mean-MAD, turnover, cardinality, etc.



  • Performing backtesting and performance analysis using functions and tools, such as backtest , backtestEngine , backtestStrategy , backtestPlot , etc.



  • Calculating and managing various risk measures and indicators, such as value at risk (VaR), conditional value at risk (CVaR), expected shortfall (ES), beta, alpha, tracking error, etc.



For example, in Chapter 9 of the book (and in folder 09_Portfolio_Optimization), you can find MATLAB code that shows how to create a portfolio object, estimate the expected returns and risks of different assets, optimize the portfolio weights using mean-variance criterion with various constraints, and perform backtesting and performance analysis of the optimized portfolio.


Credit Risk Modelling and Analysis




Credit risk modelling and analysis is a branch of financial modelling that focuses on the assessment and management of the risk of default or loss due to the failure of a borrower or counterparty to meet their contractual obligations. Credit risk modelling and analysis can help lenders, investors, regulators, and other stakeholders to measure, monitor, price, hedge, or mitigate credit risk exposures.


MATLAB can help you with credit risk modelling and analysis in several ways, such as:



  • Modelling the default probability and intensity using various models and methods, such as structural models (e.g., Merton model), reduced-form models (e.g., Cox-Ingersoll-Ross model), copula models (e.g., Gaussian copula model), etc.



  • Pricing and valuing different credit instruments and derivatives using functions and tools, such as bndprice , bndyield , bndspread , bnddury , cdsprice , cdsbootstrap , cdsoptprice , etc.



  • Simulating credit events and scenarios using functions and tools, such as simByEuler , simBySolution , simByTransitionMatrix , simDefaultTime , simDefaultCorrelated , etc.



  • Analyzing the credit risk exposure and performance using functions and tools, such as portconsolidate , portrisk , portalpha , portbeta , portrand , portstats , etc.



For example, in Chapter 11 of the book (and in folder 11_Credit_Risk), you can find MATLAB code that shows how to model the default probability of a corporate bond using the Merton model, how to price a credit default swap (CDS) using bootstrapping technique , and how to value a credit-linked note (CLN) using Monte Carlo simulation.

FAQs




Here are some frequently asked questions about financial modelling with MATLAB:



  • What is the difference between American and European options?



An American option is an option that can be exercised at any time before or on its expiration date. A European option is an option that can only be exercised on its expiration date. American options are more flexible and valuable than European options, but they are also more expensive and complex to price.


  • What is the difference between value at risk (VaR) and conditional value at risk (CVaR)?



Value at risk (VaR) is a measure of the maximum potential loss of a portfolio over a given time period and confidence level. Conditional value at risk (CVaR) is a measure of the average potential loss of a portfolio over a given time period and confidence level, conditional on exceeding the VaR. CVaR is also known as expected shortfall (ES) or tail risk. CVaR is more conservative and robust than VaR, as it captures the extreme losses in the tail of the distribution.


  • What is the difference between structural models and reduced-form models for credit risk modelling?



Structural models are models that assume that default occurs when the value of the firm's assets falls below the value of its liabilities. Structural models are based on the economic theory of corporate finance and capital structure. Reduced-form models are models that assume that default occurs as a result of a random event or shock. Reduced-form models are based on the statistical analysis of default probabilities and intensities.


  • What is the difference between mean-variance optimization and mean-CVaR optimization for portfolio optimization?



Mean-variance optimization is an optimization technique that maximizes the expected return of a portfolio for a given level of risk or minimizes the risk of a portfolio for a given level of return. The risk is measured by the variance or standard deviation of the portfolio returns. Mean-CVaR optimization is an optimization technique that maximizes the expected return of a portfolio for a given level of CVaR or minimizes the CVaR of a portfolio for a given level of return. The CVaR is measured by the conditional value at risk or expected shortfall of the portfolio returns.


  • What is the difference between machine learning and artificial intelligence for financial modelling?



Machine learning is a branch of artificial intelligence that focuses on creating systems that can learn from data and make predictions or decisions. Artificial intelligence is a broader term that encompasses machine learning as well as other aspects of creating systems that can perform tasks that normally require human intelligence, such as reasoning, planning, natural language processing, computer vision, etc.
