Training Session: Data Science Applications in Quantitative Finance


In this training session I will give an introduction to quantitative finance applications for data scientists [with no prior knowledge in the field]. I will start by discussing a few fundamental ideas such as the efficient market hypothesis and the capital asset pricing model. I will also introduce some concepts on investment strategies including portfolio theory and smart beta investing. Many such strategies are based on fundamental factors revealed by academic research, such as value or profitability, which can yield excess returns when suitably applied. There is currently a lot of interest to use alternative data sets and machine learning tools to uncover further factors, making the field exciting for data scientists.

Throughout the training session we will work on some simplified hands-on examples to illustrate the main ideas.

We will discuss the setup and subtleties of backtesting for investment strategies and define relevant metrics. Typically, a major challenge is to avoid overfitting, which we will address as well.

Although the focus of the session is investment strategies, I will also illustrate a few other machine learning applications in finance from my experience.

Participants don’t need to have prior experience in finance. However, familiarity with python and the numpy, pandas, scikit-learn ecosystem would be very beneficial.
