Complexity is neither good nor bad. It is a reality of life. It is a condition that must be addressed whether you want to model financial systems or understand the world around you. So, how can we, as financial professionals, improve our ability to deal with complex challenges and perform increasingly complex tasks? In this presentation, MathWorks Fellow Jim Tung discusses how financial companies are creating and adopting new ways to master the development of complex systems and the analysis of complex phenomena, using MATLAB.

The traditional paradigm of applying nonlinear machine learning techniques to algorithmic trading strategies typically suffers massive data snooping bias. On the other hand, linear techniques, inspired and constrained by in-depth domain knowledge, have proven to be valuable. This presentation describes the application of the Kalman filter, a quintessentially linear technique, in two different ways to algorithmic trading.

This presentation focuses on elements of PnL volatility arising from dynamically hedging VA (GMxB) contracts with a particular focus on risk-managed subaccounts. Historically, variable annuity contracts have been criticized as being underpriced in the marketplace given that the benefits and guarantees they offer are very rich. In this presentation, we show that the cost of hedging can be controlled if variable annuity contracts are written on risk-managed subaccounts.

Taking MATLAB algorithms directly into a risk analytics environment, when done well, offers significant value for a financial organization while mitigating operational and model risks incurred from recoding. In this presentation, Joan demonstrates how you can rapidly and directly embed MATLAB components into the OpenGamma Platform. He shows how you can incorporate a MATLAB function into a MATLAB Production Server™ application, declare the Java interface, create the metadata to express input requirements, register the function in the function repository, and visualize the results in OpenGamma’s risk viewer. While easy to demonstrate and extremely agile on paper, this approach could disrupt a firm’s development process. The presentation concludes with some thoughts, based on Joan’s experiences as development manager at a European bank, about mitigating risk through incorporating into automated testing frameworks and ensuring resilient performance.

The key to developing successful investment strategies is ongoing research, and this depends on the pace of investigating and understanding new ideas. Two variables can influence this speed of research progress: the organization of the research team and the tools they have available. In this presentation, Ben demonstrates how Fischer Francis Trees & Watts, the global fixed-income investment manager within BNP Paribas, used MATLAB to build such tools. They were built using standard functionality from MATLAB products, user-written toolboxes, community content from MATLAB Central File Exchange, and more advanced integration with native Java™. These tools have allowed greater team collaboration and increased research bandwidth, to enable faster research progress.

Most valuation and risk management models for derivatives are minor tweaks of Black-Scholes. Black-Scholes is a great model, whereas some of the tweaks are a step in the wrong direction. However, there are a few models based on Black-Scholes that are closer to how derivatives are used in practice and that capture essential features previously ignored. These are great models, better than all the more classical tweaks. So far so good. The main problem stopping these models from becoming more popular is that they are just too difficult to solve numerically when you have a typical portfolio consisting of many underlyings and many different types of derivatives. Can this number-crunching problem be solved?

In the aftermath of the global financial crisis, many central banks and financial regulators are considering new macroprudential policies to deal with so-called tail-risk events, the unlikely episodes of high financial distress with devastating impact on the economy. Such events have traditionally been outside the domain of mainstream macroeconomic research. To support the new policies, an entirely different family of models and modeling techniques need to be developed. In this presentation, we discuss some of the progress made in the International Monetary Fund and design simulation experiments that use MATLAB to illustrate the main issues.

MATLAB has traditionally been used for analyzing data offline, presenting analytic recommendations that were then acted upon manually. However, MATLAB supports a direct interface with data feeds and online brokers, as well as the ability to present sophisticated graphics and user interfaces—all in real time.
This presentation demonstrates an end-to-end demo trading system in MATLAB, highlighting its potential as a platform of choice. Interactive Brokers is used to demonstrate live market data feed and account/portfolio input, as well as for sending trading orders to the market. The system’s user interface showcases the hidden visualization and interactivity potential of MATLAB for tracking order executions and charting financial time-series in real time. Some best practices for improving real-time performance are also discussed.

Most of us have multiple cores as well as a graphics processing unit (GPU) in our desktop computer, with grids and clouds readily available at arm’s length. While popular hype purports that it’s easy to use such resources to facilitate massive speed-up of numerical computing at practically no cost and effort, the reality is of course somewhat different. In this presentation, Aly and Michael use MATLAB valuation and backtesting examples to look at the sorts of calculations that can be sped up by CPUs, GPUs, and server-based solutions, and they suggest a common-sense framework to help answer the questions:
Las autoridades monetarias buscan anticiparse a eventos que afecten el correcto desempeño de la economía. Así, los ejercicios de proyección de las principales variables macroeconómicas son fundamentales. Consecuentemente, los bancos centrales vienen desarrollando modelos con el objetivo de anticipar la evolución de algunas variables de interés, los cuales suelen requerir cierta sofisticación analítica. Además, es también de interés de un banco central que los distintos agentes tengan una lectura similar respecto de su percepción del entorno económico. De esta forma se fomenta la estabilidad macroeconómica y se facilita la administración monetaria.
No obstante, con frecuencia los modelos desarrollados por los bancos centrales no son fáciles de replicar por el público, por lo tanto se requiere de modelos que busquen cubrir esta dificultad. Por este motivo, en esta presentación se discutirán algunos modelos estadísticos de vectores autoregresivos de fácil implementación, cuya capacidad de pronóstico se puede mejorar significativamente con técnicas bayesianas.
Será evidente en esta sesión que MATLAB constituye una herramienta bastante versátil en la implementación y evaluación de modelos con estas características. Más aún, además de facilitar este tipo de ejercicios, MATLAB es sumamente útil para reportar resultados. Debido a la facilidad con la que MATLAB interactúa con plataformas para edición de texto como LaTeX y archivos PostScripts encapsulados para gráficos.
